North Fork Mosquito Abatement District 2015

Board of Directors of NFMAD

Board Meetings, Agendas, Minutes, Financials by Month 2015

Mapping the North Fork District

The North Fork Mosquito Abatement District covers a vast territory of different types of terrain, from Bowie to Leroux Creek canyon, with changes in elevation, an amazing variety of micro-climates, and outstanding surface rivers, lakes, creeks, and ponds, in addition to an intricate system of irrigation canals.

Within the District, there are many types of agricultural enterprises, from large ranching and farming operations to biodynamic vineyards and organic farms. The North Fork valley offers quite of variety of recreational activities including fishing, rafting, hiking, seasonal hunting, winery tours, farm tours, cottage industries producing artisanal products from vinegar to cheese, as well as seasonal community events with art, music, and food.

However, this amazing diversity is very challenging when it comes to mosquito control! Mapping the variety of terrains and the preferred breeding habitat for specific mosquito species, then matching the correct product application for the location, is essential for success in mosquito control.

Adulticide Spraying and Fogging

The NFMAD board is committed to protecting the health and safety of our residents, as well as the economic and environmental health of this valley, and will continue to use a full phase program of physical mitigation, with larval, pupal, and barrier products, before using targeted, focal adulticide spraying.  Blanket, comprehensive fogging from the air, or on the ground, has proven to be ineffective in adult mosquito control, as well as causing many issues for District residents.  Major fogging of entire towns and areas will only occur if there is a clear and present danger of epidemic West Nile, or other mosquito-borne illness in the proposed treatment area, and ALL other methods of control, including targeted, focal spraying, have failed.

August, September, End of Season operations report
The month of August began as a continuation of the operations as seen in July, with most sites throughout the District showing the presence of larvae in various instars. High winds brought different mosquito species into the District, and other districts around western Colorado had similar issues, as confirmed by the Colorado Department of Public Health and Environment.
This season in the town of Hotchkiss and the immediate areas, numbers of trapped and observed mosquitoes have been higher than last year. Heavy rainstorms right before the trapping hours also frequently contributed to the higher numbers of adults observed in traps, along with many non-mosquito insects such as midges.
While visual and trap surveillance, larval and pupal treatments, and barrier spraying continued throughout the 50 square miles of the District, Hotchkiss was again where we spent the most of our field treatment time.

This included discovering a large new source in South Westerly Hotchkiss close to the river corridor that required vast amounts of product and crew time. Larvacide treatment in the Hotchkiss area has been our main focus, however it was observed that after field treatments, with both dry and/or wet product, numbers of adults trapped dropped, only to rebound shortly after. A combination of both treatments was observed to have the longest lasting effect. Perhaps the wide fluctuation of numbers, from high to low after treatment, then returning to high, is still the result of mosquitoes entering the District, being blown in from the West, specifically along the river corridor. The river corridor, where the most consistent and highest numbers of mosquitoes are found, is also the area that is the source of the majority of the town of Hotchkiss’ mosquitoes.
The Westerly end of the District, and to a lesser degree North and South Midway, have been the target for most of our treatment activity. The mosquito sources in North and South Midway did not seem to be any more or less productive relative to last season. However one property owner in Pumpkin Hollow, who is an organic farmer, has vastly improved the irrigation throughout his property and the hatching area adjacent to his home has been eliminated. We now are able to focus on other areas of the property, and will be able to spend less money on payroll and use less product. Throughout the District more and more people are taking the personal time and responsibility to do their own physical mitigation projects, whether it is improving drainage in ditches or fields, or breaking up beaver dams. These people are decreasing mosquito habitat significantly, therefore we can make a greater impact where there is no option but treatment in other areas of the District. The added effect of stretching our mosquito-sized budget cannot be underestimated!
The East end, the Bowie area, was remarkably “quiet”. Visits were much fewer than last year and often did not result in significant treatment. The Town of Paonia also was less active than
last year, mostly due to the success of physical mitigation projects, as well as cooler weather through June. In the middle of August a street conversation and message to the NFMAD call line led to a house visit and the discovery of a Minnesota Creek area with a previously unknown pond. This pond turned out to be the cause of higher than usual mosquito numbers in an area which had not been of concern before this year. This once again underlines the importance of active community participation and communication with the District manager!
New techniques of treating with larval products in sequential steps have been very successful and efficient for the majority of “hotspot” sites in the District. Each product available for environmentally-sound mosquito-control has been studied for appropriate terrain and longevity of action. Early, middle, and late season considerations have been recorded for each site, with product application details, and trap data. This has significantly revolutionized NFMAD’s operations plan and approach, continuing evidence-based, scientific mosquito abatement.
In this way, we have reduced overall product usage, were more efficient with our man hours, while also protecting the health and comfort of our residents, as well as organic and biodynamic agricultural enterprises. The North Fork District remains one of the only districts in the state of Colorado that did not have rampant and widespread WNV positive trap pools, or high rates of human illness.
Our targeted spraying program this year has also been modified upon evaluation of effectivity to produce a greater depth of treatment, with the least amount of product and environmental impact. The majority of targeted adulticide spraying occurred in areas surrounding the town of Hotchkiss. The western and southern boundaries of the District continue to be a battleground for the crew, attempting to hold off the influx of adult mosquitoes from the areas of Delta County without any mosquito control whatsoever. This is an enormous issue for the county, and both NFMAD and Delta District #1. More than one third of Delta County does not have mosquito control unless provided personally.
In the center of Hotchkiss, the railroad remains a tremendous problem with drainage, irrigation water, and other issues…a veritable Gordian knot requiring an Alexander the Great!
Hidden Valley was treated with adulticide once, only after a large hatch of adults occurred while Chris was working with the subdivision manager, and the president of the homeowner’s association. A plan to resolve many of the drainage issues has been put in place, with a corresponding drop in mosquito-related complaints and issues.
The Midway areas, both north and south were targeted with adulticide during the season in response to trap data, and threshold variables, in addition to extensive larval and pupal treatments. Large scale physical mitigation projects continue to alter this area, with many more issues to be addressed as money allows. Unfortunately, the river corridor requires the cooperation and funding of the federal and state governments to effect significant change, hence, we must continue to apply a full array of mosquito-control products while petitioning the government for support.
Adulticiding in the areas surrounding Hotchkiss, once almost entirely the job of the diligent and much-thanked Zach Hotchkiss on his 4 by 4 Gator, has been augmented by a spray technician in a truck. Some areas are larger and harder to penetrate with adulticide fog. A combined 4 by 4 and truck spraying team can be focused based upon the type and size of the area and terrain thus is more effective and conserves product in the long run, requiring fewer treatments.
As in June and July, weather in August has again hindered our treatment and trapping programs. Wind and rain have halted and delayed both larval product application, trapping and spraying . High humidity will bring out higher numbers of mosquitoes thus spraying after rain has been observed to be more effective. But high wind and/or rain will stop us from spraying during the crucial time at dusk. Many planned spray nights were canceled and delayed during the month of August. How overall high moisture influences trap numbers is still a question, while high local winds are known to decrease the numbers of mosquitoes in traps.
Thus, we are interpreting trap data in context rather than blindly reacting with treatment.

For example:
**Late season evidence from one trap on Lund road, usually evidencing high numbers during the whole season, suddenly exhibited a dramatic decline in trapped mosquitoes for several weeks. Interference/sabotage was suspected, and it was decided to move the trap for a more realistic portrait of the resident population numbers since treatment in the area had been necessary and ongoing all season. But, when the area of the trap was explored for a more suitable location, one less likely to be interfered with, it was discovered that a resident had done physical mitigation in the current trap location, which had reduced the trapped numbers down to practically zero.
If the low trap count had been taken as a mark of success, many mosquitoes would have lived to lay eggs another day.
Personnel during this time has been the cause of difficulty, and a detriment to smooth operations. One young crew member’s job attendance became sporadic and at times non-existant. The issue was resolved eventually through management.
At the end of August, as the rains reduced both day and night time temperatures, our trap numbers decreased, mosquito hatching and larval growth slowed, so did our need for a full dry product treatment team. This crew member was released for the season at this point.
The remaining crew members continued treating the District but also reduced the territory covered as trap counts and observed issues dropped to zero. We first all but eliminated the East end of the District, and returned to Paonia with less frequency.

The larger ranches, and more sparsely populated locales to the North and South of the main river corridor were also less of a
concern. We focused our larvacide treatments mostly upon the Westerly and Midway problem areas, and responding to residents calls to the NFMAD call line. It was at this point with late-season cutting and irrigation issues arising that the Hanson Mesa area and areas “downstream” became an issue.
With two seasons under our belt we are able to recognize that although there will be variations on a theme, year to year we can expect certain weather and problem patterns to arise. There is a sequence to our approach, and to the technique with which we attack and treat the rising population of mosquitoes.
Analysis of site treatment cards from this year has yielded much valuable information. Large sites requiring costly dry product and crew hours are being evaluated for any possible physical mitigation to be completed now, and or at the beginning of next year. A list of ponds has been compiled for long-term treatment early next year, with additional ponds added as determined. Ponds that require a combined approach have been identified. In this way the scope of field treatments has been narrowed to determine the way to best and most effectively treat that site.
In Hotchkiss, and other areas of the District for private residents, door-to-door canvassing took place in September for barrier and Terminix treatments of outbuildings, sheds, eaves, under buildings, etc., to avoid hibernation of adult mosquitoes.
In September, a targeted adulticide spray occurred mid and late in the month, due to high temperatures causing multiple mosquito hatches. Trapping ceased by mid-September, mainly due to low nightly temps and subsequent inaccuracy of information gathered. Spraying was indicated by landing rates during continued surveillance by the crew, resident calls, and diligence of Zach Hotchkiss.
As the 2014 season comes to a close, NFMAD wants to thank the residents of the North fork District for the cooperation and participation shown this season. With a huge District and a tiny budget, it is essential to pull together to solve the problems of mosquito-borne illness and discomfort. We so appreciate our beautiful valley and homes!

There will be targeted spraying and barrier spraying Wednesday to Friday, weather-permitting, 9/24-9/26.  All affected residents are being notified.  Please clear the public areas by 7pm in Hotchkiss:
Zack’s BBQ
County Fairgrounds
Old and New Water Tx Plants
Certain areas of:
High School and K-8 parking lots
Coal Rd area
Lorah Ln area
Hansen Mesa Rd area
Willow Hts. Rd. area

The September 8, 2014 Board of Directors meeting has been changed to September 29, 2014 at 7pm, at the NFMAD Hive Building office.


What’s that smell??! Recently NFMAD received a few calls wondering if we had done any spraying in Paonia. The answers are; no, yes, and the explanation is below.
The source of “That Chemical Smell” wasn’t NFMAD! The town of Paonia, is using a herbacide to knock down weeds and undergrowth around town.
The mosquitoes in the area have yet to make their presence known, outside of a few areas, mostly on the fringe of town. So targeted adulticide spraying has NOT been needed.
However, we have been field testing a new organic garlic adulticide spray. It attracts, and then kills mosquitoes. Yet it’s so safe that the EPA does not require certification. It’s just microcrystalized garlic in fruit juice; Terminex can be used around and on organic farms without decertification!! We have used this product in various places where mosquitoes hatch near areas such as parks and public venues.

AND now…NFMAD protects you from both mosquitoes AND vampires!

So, if you smell garlic yes, it’s us. Keeping you safe from all sorts of blood suckers
As always please report mosquitoes, or vampire, issues to the NFMAD call line at (970) 527-6681. And remember to be responsible and cover up at dawn and dusk. Remember to empty standing water sources regularly, as mosquitoes can hatch in 4 to 5 days at this time of year!



The next NFMAD Board of Directors Meeting will be on August 11, 2014 at the Hive Building office conference room, beginning at 3pm.

Agenda available on the Meetings Page.


We have made it another week in the North Fork District with all trap pools testing negative for WNV on the RAMP reader!!!  This is a tremendous accomplishment, and a true testament to the hard work of Chris Tschinkel and the crew.

The weather has continued to be very challenging for mosquito control, with thunderstorms and wind, as well as hot days.  At this time of year, mosquitoes can breed in as little as two inches of water, in less that 5 day cycles from egg to flying and biting adult.

Given that other Districts and places in Delta County have been having positive trap pools for WNV, and a few human cases have been reported, it is essential to continue to protect yourself and your family from mosquito bites!  Please be particularly careful at dusk, and just after rainstorms in the evening.  If you are traveling in the town of Delta, or Grand Junction area, take care to avoid areas by the rivers, again especially at dusk.

Trap counts in the Hotchkiss area continue to rise and fall depending on the rain storms and the night of trapping.  We are now in the early days of the Delta County Fair, and the crew has continued to keep the Fairgrounds, and all parks and recreational areas under tight control, using the full array of products available for safe mosquito control.

The BMW rally in Paonia Town Park was very successful from a mosquito control point of view, and the first Picking in the Park event on 8/7/14 was widely attended and received high marks for comfort and safety from mosquito bites.

As we head into the new school year, all District schools have been kept under control, with particular emphasis on playing fields and surrounding areas with culverts, drainage, or irrigation tail waters.

As always, if you are seeing adult mosquitoes, or breeding habitat, please call Chris Tschinkel at the main NFMAD number, 527-6681.  With a 50 square mile District, and a mosquito-sized budget, we rely on the support and diligence of the District’s residents.  Thank you!


July 30, 2014
As of today, ALL NFMAD trap pools have continued to test negative for West Nile Virus, despite Delta District #1, and other counties with all trap pools testing positive!!!

Chris Tschinkel and the crew are fighting hard, particularly on the southern and western boundaries of the District, by the town of Hotchkiss.

As the Delta County Fair approaches, the weather has been extremely hot, with a lot of rain in the last week or two, causing mosquito breeding/hatching in less time than the usual cycle, in as little as 4-6 days from egg to flying adult.

Please continue to police your property, your irrigation, and to practice personal protection, particularly in Hotchkiss.  Given that a large area surrounding Hotchkiss is not within either District, if you are working or live in these areas, it is imperative to do whatever is possible to protect yourself and your family.

RED ALERT!!!!!!!!!

NFMAD was informed by Ken Nordstrom, Director of Public Health for Delta County today that ALL trap pools from Delta District #1 for the week of July 8th have tested positive for West Nile Virus.

Mesa county has also had multiple trap pools test positive for WNV presence in the last 3 weeks.

NFMAD trap pools have continued to test negative on RAMP through the week of July 8th, and trapping for this week has just begun.

Please, please be very cautious!!!! Use repellants, and clothing, avoid outdoor activities at dusk, and police your property. If Delta District #1 has all traps testing positive, mosquitoes carrying WNV are moving in our direction. The crew is out working hard to control breeding and using all phases of treatment to kill adults, however you must protect yourself and your family, particularly if you live in an area of the southern and western borders of the District.


The next Board of Directors meeting will be on July 21, 2014, at 2pm in the Hive Building NFMAD office.

Operations and News around the District


July 11, 2014

The July 4th celebrations in the North Fork District were successful from the viewpoint of mosquito control, with many residents commenting favorably.  The trap counts in Paonia are staying very low, an excellent result of physical mitigation projects and judicious use of barrier and attractant bait spraying.  The Paonia Town Park Cherry Days event was almost virtually mosquito-free.  A huge thank you to Chris Tschinkel and the crew!

NFMAD is keeping a tight watch on all the District parks and recreation areas as summer events continue to draw crowds, however it is always a good idea to keep up with personal protection, using clothes and repellants,etc., when attending events at dusk in the summer, particularly at parks with large grassy areas and shrubs…the favorite daytime “resting” areas for mosquitoes.

The District is still experiencing adult mosquitoes blown in from the south and west boundaries in Hotchkiss, from other areas in Delta and adjoining counties, and Chris Tschinkel and the crew are fighting hard to prevent adult mosquito breeding in these areas.  There has been targeted adulticide spraying in south and west Hotchkiss, mostly on public land such as the Delta County Fairgrounds, to support this effort and keep the town of Hotchkiss under control. The Midway areas of Bell Creek Rd., Coburn Rd., and Lund Rd., have also been target sprayed to keep populations of adult mosquitoes down.   Please give Chris a call at 527-6681 if you are seeing adult mosquitoes, and thank you for the continued efforts on your own property eliminating standing water, changing bird baths, and generally keeping an eye out for issues, as we are now in peak mosquito season.

All trap pools have been tested for the presence of West Nile virus using the RAMP reader purchased last year, and have tested negative in all sentinel traps, as well as additional traps set coming up to the holiday weekend.  Sadly, Delta District #1 and Mesa counties have now had multiple trap pools testing positive for WNV, so please, please use extra caution in those areas, especially at dawn and dusk.  The North Fork District is one of the few areas in Colorado still testing negative, of the Districts that had issues in previous years.


June 30, 2014

In preparation for the coming July 4th holiday celebrations, there will be a lot of mosquito control activity this week, particularly in our Parks and Recreational areas.

Barrier and Attractant Bait spraying will be happening after dark Monday-Thursday throughout the District, dictated by weather.  The windy and stormy conditions of last week have now become windy and dry, also challenging, so the crew has been prepped and ready to go for many nights, only to be derailed by winds stronger than optimal.

Please vacate the parks by 9:00pm this week to support the crew!  Here’s to a safe and enjoyable celebration of our nation’s independence!!!

June 25, 2014

Wednesday, June 25/14 News
Over the last week high winds have brought adult mosquitoes into the southern and western edges of the District and the crew has been hard at work preventing “interlopers” from laying eggs, using the organic Terminix product and hardcore surveillance through trapping and site checks. Across western Colorado, high winds, rains, and escalating temperatures are causing adult mosquitoes to appear in areas where no breeding sites have been found, causing havoc for mosquito control districts! Please call the NFMAD main line, 527-6681, if you are seeing adults from your deck or property in general, and thank you so much to the residents calling in information to Chris Tschinkel. The District is stretched financially given the early start back in April with the appearance of larvae in various locations of Hotchkiss, and the prediction that September will again be full-on mosquito season this year. The crew has successfully prevented the majority of breeding areas found from hatching into flying adults using larvicides and pupacides, but again, the amount of larval products and the payroll costs are higher for April, May, and June, as a result. As we are now less than 2 weeks from the July 4th celebrations, barrier, attractant bait, and adulticide targeted spraying has commenced where indicated. Trap counts are being kept under strict controls, and all RAMP testing has come out negative for the presence of West Nile Virus in the North Fork District, while Delta District #1 and Mesa County have both had WNV positive trap pools of adult mosquitoes. Please continue to protect yourself and your family from mosquito bites, especially if you are working or traveling through Delta, Grand Junction, or other areas in the Front Range of Colorado where multiple WNV positive trap pools have been reported. Dawn and dusk are the most significant times for culex mosquitoes, however there is now evidence that aedes species may be carrying both WNV and W. Encephalitis, in addition to heartworm for dogs and cats. As you are planning your July 4th celebrations, please include a good mosquito repellant, and continue to police your own property.

Spraying Notices


Notification of adulticide spraying will occur when the routing comes within 200 feet of a residence or boundary of organic farms/agriculture.  All efforts are being made to map organic/biodynamic agriculture and bee hives, and laminated signs are available for posting on gates, fences, etc., for pesticide-sensitive residents and organic agriculture so that there is a consistent, easily recognizable sign for crew in the event of truck-mounted fogging. Please call 527-6681 to receive a free laminated sign.

Notification of targeted and focal adulticide spraying will be made whenever possible on the Website News/homepage, the Facebook page for NFMAD, for public areas, and to the affected residents in town if the targeted area is within 200 feet of a residence.

NFMAD is currently the only mosquito control district that gives notification for adulticide applications in the state of Colorado, and the field manager will continue to make every effort to inform the public when possible.

If adulticide is applied using the truck mounted sprayer rather than the smaller backpack handheld or ATV units, notification extends to every property in the immediate area, by door hanger, telephone, and/or a crew member going door to door, again whenever possible.

July 30, 2014

Due to trap evidence and other threshold factors, the following areas will have targeted adulticide spraying. Please clear the public areas by 9pm. Any residents within 200 feet of a targeted zone have been or will be notified:

Between Wednesday and Sunday evenings, depending on weather (wind and rain):

Train Bridge Rd. area

Hotchkiss Old Water Treatment Plant

Delta County Fairgrounds

Carsten’s/TriCounty Gravel

Coal Rd area

Zack’s BBQ area


July 14, 2014
The recent soaring temperatures with thunder storms and showers has caused an increase in female mosquitoes looking for blood meals to lay eggs. Please be very cautious at dusk in particular!

Due to trap evidence and other threshold factors, the following areas will have targeted adulticide spraying. Please clear the public areas by 9pm. Any residents within 200 feet of a targeted zone have been or will be notified:

Monday or Tuesday nights, weather dependent:
Areas behind the Redwood Arms motel, extending to Farnsworth Gravel and the Storage Bins in Paonia.

The lower gulch at the Hotchkiss Willow Heights Park with handheld low flow sprayers.

Tuesday or Wednesday nights, again weather permitting:
The Lund, Coburn, Bell Creek, and Corky roads areas

Wednesday, Thursday nights, weather permitting:
Hotchkiss Old Water treatment plant, Delta county Fairgrounds, Zack’s BBQ, areas of Lorah Lane possibly.

July 8, 2014

Due to trap evidence, and threshold factors, there will be targeted spraying, depending on weather, in the following areas:

Tuesday, Wednesday, or Thursday 7/8 through 7/10:

The Hidden Valley area, Bell Creek Rd. area, Coburn Rd. area, and Lund Rd. area.

Wednesday, or Thursday 7/9 through 710:

Hotchkiss Old Water Treatment plant, Delta County Fairgrounds, Zach’s BBQ, a few private property areas more than 200 feet from neighbors or public areas.

June 30, 2014

Due to trap evidence, threshold factors, and the upcoming July 4th holiday celebrations, there will be targeted spraying in the following areas:

Monday or Tuesday 6/30 or 7/1, depending on weather:

Rodeo Grounds, Bell Creek Rd. area, Coburn Rd. area, and Lund Rd. area.

Tuesday, 7/1, or Wednesday, 7/2:

Hotchkiss Old Water Treatment plant, Delta County Fairgrounds, Zach’s BBQ, a few private property areas more than 200 feet from neighbors or public areas.

All parks and recreation areas will be barrier and attractant bait sprayed after dark between Monday and Thursday evenings….please vacate by 9pm to support the crew.  These areas will  include:  Delta County Fairgrounds, Willow Heights Park, Zach’s BBQ, Rodeo Grounds, Paonia Town Park, Apple Valley Park, Volunteer Park, and several large unincorporated areas.


June 25, 2014

Due to trap counts, resident reports, historical evidence, and upcoming July 4th events, southern and eastern Hotchkiss areas will be adulticide sprayed on Thursday night, June 26, 2014, weather permitting.
These areas will include:
The Old Water treatment plant, the Delta County Fairgrounds, private properties on the eastern borders in areas that are more than 200 feet from property lines, Zack’s BBQ, and several private property areas in southern Midway, east of Pumpkin Hollow Rd.

Barrier spraying and attractant baits will also be applied to Willow Hts. Park, areas of the Fairgrounds, and other event areas in Hotchkiss, the Rodeo grounds in Midway, and Paonia Town Park, Volunteer Park, and Apple Valley parks in Paonia.   Areas of the River Park in Paonia are being closely monitored since these are designated conservation wetlands.

Please clear these areas before dusk!  All affected residents have been personally contacted.  We so appreciate your cooperation and continued support as we work hard to break the epidemic cycles of WNV in our valley!!!


Due to trap evidence, resident reports, and upcoming events, ZacK’s BBQ will be target sprayed with adulticide tonight, weather permitting. In addition, the old water treatment plant, and the Delta County fairgrounds will be treated, again depending on temperatures and weather. Please clear these areas by 9:30pm, and thank you for your cooperation!

Mosquitoes carrying West Nile Virus were found in tests in Adams, Boulder, Weld, Delta and Mesa counties, specifically in Delta District #1 area, based on PCR testing through Public Health. The weather has been unusually cool at night, but that is all changing as of tonight, 6/19/14, with predictions for the Hotchkiss area to have a night low in the 50’s. Paonia area is still reading at the high 40’s in the evening, which is keeping traps counts flat, and in most of the sentinel traps, non-existent, however, by Saturday night the predictions are again for higher nightly temps. Please, please, protect yourself and your family during dawn and dusk since warmer nights mean adults could hatch in breeding areas the crew has not discovered or can’t access.



The June 9th Board Meeting at 2pm in the Hive Building Office has been cancelled due to illness/family illness amongst the board of directors. Stay tuned for an updated meeting time.


Join the Mosquito Swat Team



Mosquitoes are not only a nuisance but can impose certain health risks.  When outside, especially at dawn or dusk, it is important to protect yourself with long sleeves and long pants to prevent becoming a victim of these pesky critter’s bites!

Mosquitoes are attracted to the sweet, flowery scent of hair and body products, as well as scented candles and other garden ornaments.  Avoid using perfumes or fragrances of any kind when planning to be outdoors.

Natural mosquito controls can help tremendously to rid sites of mosquito breeding and adults.  Take a walk around your property to police for any signs of mosquito larvae, pupae, or adults that are flying.  If you see areas of stagnant water, or signs of mosquito breeding, please call NFMAD Swat Team leader, Chris Tschinkel at 527-6681.

Collections of water, such as ponds, irrigation tail water, puddles, tires, birdbaths, pet bowls, annual flower pot bottoms, discarded cans and jars, and other available shallow, standing water spots, are all prime breeding sources for adult mosquitoes.  Mosquitoes only require 2 inches of water!

Roof gutters and ditches that accumulate water must be cleaned on a regular basis, as these are also prime breeding areas for adult mosquitoes.  Water standing for only 4 days, above 50 degrees, can hatch thousands of mosquitoes!

Mosquito fish, the common name of Gambusia Affinis, will eat mosquito larvae at a phenomenal rate of more than 100/day.  For more information, call Chris at 527-6681 if you are interested in hosting mosquito fish in your pond.

Nature does provide us with a few natural mosquito controls that aid in getting rid of mosquitoes…creatures such as bats, toads, hummingbirds and dragon flies are all mosquito-eaters.  Hummingbirds actually eat mosquitoes as 65% of their diet!

In addition, because weeds and other forms of vegetation can be a harbor for adult mosquitoes, grass should be cut and weeds managed on a regular basis to decrease mosquito “resting” spots.  Additionally, bacteria that are safe for everyone except mosquitoes, black flies, and midges, are used in commercial control products, such as mosquito dunks, bits, and donuts, available at your local Paonia Farm and Home store.

So!  As a new member of the Mosquito Swat Team, we want you to know we appreciate all the help in controlling  mosquitoes in our beloved North Fork valley…even killing ONE little mosquito makes a big difference, and helps us to help you! Put the Swat on your backyard mosquitoes, and fight the bite!!!







The next Board of Directors meeting for NFMAD will be on Monday, May 19, 2014 at the Hotchkiss Chambers Room, starting at 5:30pm.



NFMAD in partnership with Delta County Libraries and Paonia Farm and Home, is collecting clean, used plastic 1.5 and 2 liter plastic bottles to make into mosquito traps.

On June 4th, at the Paonia Town Park, the Summer Reading program launch event will take place. Mosquito traps will be made out of the collected plastic bottles for each child to take home.

Instructions for making these simple, effective traps will be provided for those not able to attend the 6/4/14 event, and will be available at the Libraries in Hotchkiss and Paonia, both town halls, Paonia Farm and Home, and Ace Hardware stores.

Additionally, the instructions will be available at (

Call Chris Tschinkel at 527-6681 or email ( with questions, or if you have a stash of bottles we can pick up.

May 1, 2014

A huge thank you to Tom Wills for serving on the Board of Directors of the Mosquito District for the last 18 months!  Thank you for all your input and support, helping to make the 2013 season a success, and the early 2014 season off to a great start. We so appreciate all your hard work!

Tom Wills is now serving once again on the Hotchkiss Town Council, and will continue to volunteer efforts towards strategic planning for the District’s future.
A vacancy on the Board will be declared as of the May 19 meeting. Any adult resident of the District or property owner within the District is eligible to apply for the appointment.  Please send a letter of interest to any current Board member or call 970-527-6681.




NFMAD is seeking full and part time Field Crew for the 2014 season.
Applicants must be 18 years old or older, have a valid Colorado Driver’s license, be mature, honest, self-motivated and in good physical condition.
$12/hour. NFMAD is an equal opportunity employer. Call 527-6681, email (  or write to PO BOX 1822 Paonia, CO 81428 for an application



Happy Easter to all!

The next meeting of the NFMAD board of directors will be on Monday, April 21, 2014  at the Paonia Library community room, from 5:30-6:30pm.  The Agenda for the meeting is on the “Meetings” page.






NOTE:  This is an excellent time to clean out your irrigation ditches, ponds, etc., while doing general Spring Clean Up.  Mosquitoes will lay their eggs in as little as 2 inches of standing water, so please pay close attention to areas of poor drainage or pooling of irrigation tail water, particularly if you have experienced issues with adult mosquitoes in the past.

Chris Tschinkel, NFMAD Operations and Field Manager, is available for site evaluation and crew support with physical mitigation of breeding areas.  Call 527-6681  or email ( for an appointment.

Chris and two crew members have been hard at work over the last month on physical mitigation of potential and known breeding areas of mosquitoes, improving drainage, and coordinating with District agencies and leaders to make the North Fork District far less appealing to mosquito breeding.

As always, if the breeding sites can be altered or destroyed, a dramatic decrease in the need for product application and crew hours occurs, allowing the District to provide more service with our limited budget.


Earlier in April, the NFMAD field manager, Chris Tschinkel, set up a controlled burn on private property on Woods Rd. in Hotchkiss. This area was a troubled spot for mosquito breeding in previous seasons.  Hotchkiss Fire Chief, Doug Fritz, (pictured below)  and several firefighters, worked closely with Chris to maintain absolute safety during the burn.  A foam that is soap-based was sprayed around the area to contain the flames.

A huge thank you to the Hotchkiss Fire Department for their support and commitment to mosquito control!

Please, please call for support if attempting a burn on your own property!  The weather conditions have to be perfect, low wind speeds, damp ground that is not wet, etc., and it was amazing to have experienced firefighters in control.

NFMAD March Board Meeting:  Hotchkiss Chambers Room  5:30pm  3/17/14

Agenda posted on the “Meeting” page here and also at the places of announcement.

Exciting News in the mosquito control product department!

NEW IN 2014:  Terminix All Clear

The first completely non-toxic mosquito control product that will kill adult mosquitoes within 4 days at a rate of 92-97%.  This product is finally available, based on extensive research and development by Israeli scientists.  Rain Klepper has been studying the research and threshold trials over the last 18 months, with great excitement at the possibilities for the North Fork District.  Terminix will be available for the first time in May of 2014, manufactured in Israel and limited in supply until 2015, when manufacturing will take place in the United States.

Terminix is basically micro-encapsulated garlic oil, with a sugar attractant and citric acid.  It does not require an EPA registration number, nor any filing of NPDES paperwork due to a rating of 100% non-toxicity.  This means the product may be applied around water, organic agriculture of all types, at schools and parks where there are minor children, etc.  This is tremendously exciting for advanced mosquito control working hand in hand with organic/biodynamic agriculture, as well as areas of denser population.

Terminix will last up to 4 weeks, unless there are heavy rains, and does not break down in sunlight.  It is non-toxic to predator species and bees, as long as it is not applied to a flower, or bud, which is easy for the crew.  The product will attract adult mosquitoes 25 feet in all directions from the point of application, hence acting as both a lure and a defensive wall, depending on point of application.

Chris Tschinkel and the NFMAD board are actively drafting operation plans to put this product into immediate use.



Happy New Year!

The board and field manager have been working on plans for the 2014 season during the winter cold…physical mitigation possibilities are being explored, particularly for locations that are inaccessible once the irrigation canals come on in April.  Controlled burns are also being explored as this method can only be safely used during late winter/early spring.  Please call the 527-6881 NFMAD telephone number if you are aware of locations that may be added to this list.

2014 Proposed Budget notes


Due to previous trap counts and other threshold variables including the avoidance of adult culex hibernation, NFMAD will be doing a targeted adult mosquito knockdown spraying in the some or all of the following locations depending on visual inspection of larval control, in very specific areas tonight, 9/19/13, between dusk at approximately 7:30pm and dark, weather permitting. If the weather doesn’t cooperate (winds and/or rain) then we will reschedule spraying as soon as possible over the next few nights in these areas:

Hotchkiss area:

-parts of the Fairgrounds

-Zack’s BBQ area

-Cedar Rd. North of the RR tracks and above Sheppard’s Lane but below the top of the hill.

-Train Bridge Rd areas

-Old Sewer Lagoon access Rd, beginning from Cedar Rd south of town at the bridge and continuing to Z. Hotchkiss’ fields.

-Behind the Hometown cafe to the trailer park and Carsten’s

-Private property area on Hansen Mesa

-Areas of Riverside Dr., all private properties.

As always any residences within 200 feet of the events have been notified.

Please be aware that there is still evidence of West Nile Virus in the Valley. Mosquitoes season IS winding down, but WNV mosquitoes are most virulent at this time. SO, take appropriate precautions if you are out in the evening hours. Long sleeves and repellent.

PLEASE recheck your yards for standing water, and look around for places culex mosquitoes might choose to hibernate, including under your home, sheds, planter pot bottoms, compost buckets, etc.. As the nightly temperatures drop, more adult mosquitoes will be coming into residential areas seeking warmth and a place to lay eggs before hibernating.  It isn’t over yet! Please be vigilant!










Due to trap counts and other threshold variables including the avoidance of adult culex hibernation, NFMAD will be doing a targeted adult mosquito knockdown spraying in the following locations, in very specific areas tonight, 9/11/13, between dusk at approximately 7:30pm and dark, weather permitting. If the weather doesn’t cooperate (winds and/or rain) then we will reschedule spraying as soon as possible over the next few nights in these areas.


Note:  The previous notification for spraying on 9/5/13 was not accomplished due to winds, stormy weather, and other uncontrollable factors.  Those locations have been added to this list:

There will be targeted spraying in the Delta Cty. Fairgrounds area this evening, weather permitting, in an effort to control large amounts of adult mosquitoes hatching in irrigation tail water that has collected into the low area south of the Fairgrounds.


Red Alert: 

A WNV positive was tested on the RAMP reader on a trap pool from the Lamborn Mesa area.  There is a case of human WNV in the area, what is known as “uncomplicated fever”, although there is nothing uncomplicated about how sick this man is feeling.

Please take extra precautions at dawn and dusk, and police your property. We are coming into the end of the season and trap counts are dropping due to the cooler nighttime temperatures, but please don’t be fooled…older culex mosquitoes carrying WNV can still make you very sick regardless of the date on the calendar.

NFMAD will continue trapping and RAMP testing until September 15th, and/or nighttime temps drop well below 55 degrees, and will continue past 9/15 if indicated in any area that tested positive for WNV on RAMP this season.

Many other districts stopped trapping in late August, however the North Fork area is still experiencing temperatures in the high 80’s-low 90’s.

8/28/13 Notice:

Due to high trap counts and other threshold variables, the following locations will be target sprayed in very specific areas with adulticide tonight between dusk and dark, 8/28/13, weather permitting. If the weather doesn’t cooperate (winds and/or rain) then we will reschedule spraying as soon as possible in the next few days:

Paonia area: Bell Creek Road and Lund Rd. One target area on Lamborn Mesa

As always any residence within 200 feet of the events have been notified.

8/26/13 Notice:

8/29/13: The following comments were copied from the Paonia Message Board:

Lulu Volckhausen:

I have to make a comment here. First of all, lets look at the numbers. On 8/28/13 the Bell Creek trap had 23 Aedes mosquitoes, 9 culex, 11 ochlerotatas, 5 culesita, 2 anopheles for a total of 50. Lund Rd. had 72 aedes, 22 culex, 13 culiseta, 14 ochlerotatas for a total of 121. Lamborn Mesa had two traps set one had a total of 14 with 8 culex, the other total was 36 with a total of 20 culex.

Rain Klepper:

Hi Lulu, Traps counts are not the only factor in the decision to spray an adulticide…the RAMP tests were run this morning on these traps that were counted yesterday, and one of the Lamborn traps with low numbers came out positive. We have consistently seen the RAMP positives for the presence of WNV be totally independent of the number of culex in the trap, with several this season postive with only 3-5 culex present. This is one of the real strong points of the RAMP reader giving direction to operations rather than just relying on trap numbers. Also, there were a number of places in the Bell Creek Rd. and Lund Rd. areas with Instar 3/4 larvae, pupae, and pupal skins, that have been consistently treated with a variety of larvicides without complete mitigation, hence targeted spraying in those areas. Both were over threshold, and the other variables (hotspot from the past, human WNV case in the area, etc) were all present.

Following are the article by Tom Wills for the Merchant Herald newspaper, and Chris Tschinkel and Rain Klepper’s July Operations Report and General Update on the NFMAD:


NFMAD, Despite Severe Challenges, Whups Mosquito Butt

By Thomas Wills (NFMAD Secretary – Treasurer) incorporating reports from Chris Tschinkel and Rain Klepper

As was expected the month of July was the height of mosquito season for the Valley and the North Fork Mosquito Abatement District. The public did a good job in keeping us informed by calling information on voicemail line. Using this information combined with the district’s expanded trapping program NFMAD field manager Chris Tschinkel and his crew responded aggressively with concentrated larvaciding in problem areas but also backed up with adulticide fogging where warranted to knock down the adult mosquito populations and allow the larvaciding program time to catch up.

One of the larger challenges of the period was the appearance of West Nile positive mosquitoes in several areas around Paonia and in Bowie. Quick detection was made possible by the District’s new RAMP testing equipment, which can test trapped mosquito pools in minutes, something which used to take up to two weeks or more when the trapped mosquitoes had to be sent in to State laboratories.

The crew responded to the positives immediately, following our operations plan by hand (backpack) fogging the positive pool areas and then doing ever expanding concentric circle searches of the positive areas to determine where the mosquitos were coming from. Such areas were aggressively treated with larvacide and continually monitored afterwards. This strategy appears to have worked very well since no subsequent positive for WNV were detected in those areas after the initial ones.

As a side note, there have been no West Nile positives detected in the Hotchkiss area this season. Board president Rain Klepper credits board member Zach Hotchkiss’ extensive volunteer work with keeping the situation around the Town manageable.

The next challenge was the sudden rise of general mosquito numbers, particulary in the heavily irrigated areas between the towns as well as in historic problem areas along the river. Much of the issue was related to seasonal high temperatures coupled with over-irrigation issues along with the July monsoon rains that created instant mosquito habit where none had been before. Such sudden hatches of mosquitoes call for use of the district’s big guns and there we ran into a problem. Though the two truck-mounted sprayers had been tested and calibrated earlier in the year, as we attempted to bring them into full service first one and the other experienced problems. Upon inspection it was determined that the units had not been properly maintained over the past few years when they had seen little use.

Thanks to some very skilled work on the units by Hotchkiss Auto and most particularly by Dan Stucker of Hotchkiss Rentals the units were finally brought on line. Field Manager Tschinkel had high praise for Stucker’s work. “He pretty much saved the day,” Tschinkel wrote in his report.

The period also highlighted the district’s need for a wider range of equipment including at least one ATV, and ideally several. Truck mounted units are limited in the areas they can get to and the backpack sprayers require a human back and a pair of legs and a lot of time and walking. While the backpack units purchased at the beginning of the 2013 season are invaluable, many areas could be quickly and more efficiently reached by ATV. This has been proven in the Hotchkiss area where, as mentioned earlier, board member Zach Hotchkiss has taken on the lion’s share of the adulticiding application duties, not only on his family’s extensive properties that lie between the town and the river, but also adjacent areas including the Delta County Fairgrounds and Zack’s BBQ area. Hotchkiss uses his own ATV as a mount for a District-owned spray unit. The ATV mounted unit has been useful in delivering limited product to a specific area with minimal drift. It would be ideal in treating many properties along the river and in the Midway area.

In order to meet the rising mosquito numbers, as well as dealing with festival season with Cherry Days, the BMW rally and the Delta County Fair in succession, during July NFMAD hired two additional crew members. According to Tschinkel his entire crew has shown true dedication to their job of protecting the public’s health.

In August the nighttime temperatures began to drop, which limited nighttime and early morning mosquito activity, although the continuing rain continues creating issues. And there is also the fact that the schools within the District are now back in session and that will mean evening sports events. The District has already began physical mitigation efforts around playing fields and are exploring all option to make sure that the outdoor activities including football games are safe while also making sure that there is no unnecessary pesticide exposure.

One other important issue was revealed during July when it was reported that a local man, possibly a former board member, had been illegally spraying malathion in the Hotchkiss area using a privately owned, truck-mounted unit on public roadways. The truck and operating sprayer were observed by several eyewitnesses on at least one occasion. If a local resident observes such a vehicle in operation, that is not a NFMAD truck (green with a logo on the doors), they are urged to please call 911 emergency so that the driver can be apprehended in the act. Local authorities have been alerted to the serious violation of State and federal law.

Financially the District is working within the available funding but it is certainly a challenge in light of the needed new equipment purchases this year. Also District has found the RAMP reader so valuable as a tool that it has purchased 300 test kits so far, rather than the expected 100. It costs the District $18 (not counting labor) per WNV test done on the RAMP. As a long term goal the District plans to gradually build up enough of a reserve to respond adequately during the bad WNV years.  This may require going to the taxpayers and asking for additional funding within the next two years.

The WNV cycle seem to be on a 4-5 schedule between emergency level years. So far locally 2003, 2007, and 2012 have been the prior high WNV years so the District needs to have a good sized contingency reserve in place before the 2016/2017 seasons.  The cycle appears to be driven by the time it takes for covid bird populations to recover as well as other factors.




July NFMAD Operations Report

By Chris Tschinkel and Rain Klepper
The month of July was similar to June, but with a higher degree of intensity. We were presented with our first cases of traps with WNV positives on RAMP, and large numbers of mosquitoes in the traps.

Although ATV fogging in the area surrounding the Hotchkiss area went very smoothly, in great part thanks to Zach H., truck fogging in Bowie, Paonia, and Midway was delayed and halted off and on over the better part of three weeks due to endless issues with the sprayers. This was incredibly inefficient in both time and product, given the difference in territory covered by hand held units vs. the truck mounted sprayers.


An alternate fogger was brought up to speed, but it also came with issues of its own, due to lack of use for at least one season or more, inadequate over-winter storage, and preseason prep, all creating a cascade of multiple problems. The issues could not be solved by our in-house mechanic. Hotchkiss resident Dan Stucker, of Hotchkiss Rentals, quite literally saved the day, volunteering to work on the fogger mechanism, and doing so quickly and efficiently.
During the time our foggers were non-operational, there were additional issues that occurred as a result including quite a few hours of crew members out attempting to fog, then having yet another problem with some part of the spray unit, increasing the response time to trap counts over the threshold and/or WNV positives.


Since we are setting many more traps this year in perimeters around a positive, the delays were even more annoying, requiring a lot of effort to overcome.

The residential areas along the south side of the North Fork, AKA “Midway” began to show high trap numbers after the July 4th holiday and the residents began to leave voice mail messages on the NFMAD line. When a fogger seemed as if it could be used I (Chris) went door to door talking with people about imminent spraying and discussing any questions or issues they might have. Door hangers were left if no one could be contacted. There were several proposed/promised sprays that were delayed, most often by recurrent mechanical problems issues, but also often by wind and rainy weather that would not allow safe fogging.

Once both foggers were back up and running and computer droplet tested once again, we were finally able to send out the crew in two trucks fogging in two locations in the same night.  Everyone on the crew has stepped up with extra hours and split shifts so that we are not behind the curve knocking down adult populations and prepping for events.

In the days prior to Cherry Days, the crews coordinated larviciding treatments in the Paonia area, concentrating upon the areas north of Town Park east and west along the river, and to the west and north sides of Volunteer Park. Prior to Cherry Days, Volunteer Park was fogged due to exceptionally high trap counts in the park boundary along Kropp’s organic orchard, along several close-by traps, and a one-off trap set along another boundary.

Trap numbers around Town Park were low, so fogging was not even considered.  A barrier spray was done around the perimeter of the park.

For the Paonia BMW rally the area received a similar treatment, though with trap numbers slowly rising in the Paonia town park trap, a thorough barrier spray was done the night before BMW campers arrived.  Subsequent trapping was again below ten total mosquitoes, with very few culex species, and all testing negative on the RAMP reader.

By and large barrier spraying and intensified larviciding prior to any public event, both large and small, has diminished the appearance of mosquitoes, and we have received excellent feedback from residents and visitors.

The Paonia library outdoor music series that takes place at dusk was barrier sprayed and there were no complaints. Cherry Days was virtually almost mosquito-free, and so was the BMW Rally, however that could also be attributed to rain on several days.

The rise in trap numbers mid-late July could be seen as the concurrence of late-in-the-day showers, high daytime temperatures, and many farmers and ranchers turning irrigation back onto hay fields after the first harvest, causing a lot of tail water to collect in previously unmapped places.  All of these factors increased the mosquito breeding areas in ditches and fields while the river also began to dry down, creating puddles that were prime breeding sites.

The entire river corridor was surveyed, and larval-treated for any potential or present breeding.  The crew spent many days hauling product in backpacks while assessing the entire N. Fork of the Gunnison river, through the District.  A lot of valuable information has been added to the grid maps for this season, as well as looking to the future.

Fogger malfunctioning did not allow us to knock down adult mosquito populations as rapidly as needed several times in July, and/or that hatched in areas unknown prior to this part of the season.  A lot of time and energy was claimed by the cycle of “repair, clog, break, hose blow up, repair, etc.” of the truck fogger units, which also contributed to the crew not having enough time to search further afield for breeding areas as quickly as possible, as spraying with the hand held units takes far more time.

NFMAD’s equipment must never be left in such a poorly maintained state again.  Without the combined volunteer efforts of many people, this could have turned into a highly expensive equipment replacement bill that would have effectively destroyed the budget.

The maps from last season were not changed or updated since approximately 2008, and were woefully inadequate to plan operations, so in 2013 a lot of site evaluation has been necessary to realistically track down the breeding areas feeding some of the trap sites all over the District, particularly in lower Hotchkiss, Midway, and the completely unmapped grids in the Lamborn Mesa area.  The perimeter trapping around sites with high trap counts and/or RAMP positives, and the crew combing the area in widening concentric circles has added tremendous information to the maps, and will serve the District well into the future.

As trap results climbed and areas to be treated increased, the field

crew roster was augmented by the hiring of two additional personnel. New and seasoned crew have been trained in both trapping, dipping and matching larval products to terrain, and the safe applications of barrier spray and adulticide targeted spraying and truck fogging.

Meticulous records are being kept of all product applications, in full compliance with state and federal mandates.  Many new forms have been created to ease the paperwork burden, and increase communication with residents. These forms include door hangers with information if a resident is not at home during a personal visit, notice of a WNV positive trap pool in the area, and notice of adulticide application. A comprehensive listing of telephone numbers for each street in Midway and parts of Paonia is being created, and the Delta County Mapping software has been instrumental in identifying individual residents by name and property.  This is also on the list for the winter/early spring as eventually, we would like to have every resident’s telephone number for ease of contact.

The additional crew members worked well as our focus became more centered on treating larger areas such as fields of standing irrigation water, and responding en mass to traps with WNV positive RAMP tests.  We have typically been setting up to 6 traps in a perimeter around the positive trap site, and the crew fans out on foot in concentric circles, widening to a half mile initially, then another half to three quarters of a mile in the next week as follow-up.  This plan is working very well to contain and eradicate the adult culex population.  Thankfully, all WNV positive trap pools are now testing consistently negative on RAMP.

The RAMP reader has shifted the operations plan significantly, allowing us to focus more aggressive treatment where needed.  Given the budget, the RAMP has made it possible to have a full crew, an appropriate diversity of control products, and the ability to continue surveillance and treatment well into September, by having the feedback of the testing support product application and search missions.

As in June, the rotation of the crew cycles from the Hotchkiss area, east along south Midway to Paonia, then east up Minnesota Creek and further east to Bowie, then back west along north Midway and returning to Hotchkiss, continuing in the same pattern. At the same time, one or more crew members would respond to a high trap count, a WNV positive or alert, an upcoming event on the calendar, and/or voice mail message and resident request or complaint.

All WNV occurrences were treated ASAP, with all crews converging upon the trap site, then fanning out up to 3/4 of a mile in a widening circle on a search and treat mission.  Every residence within that zone was visited and I (Chris) spent many hours talking with the people and walking their property evaluating possible breeding terrain and answering questions.  The crew made tremendous efforts to larvicide any standing water that might contain mosquitoes contributing to the trap count, or that could become a source in the future.  A lot of product had to be carried long distances to accomplish this type of perimeter treatment, but it has paid off in every area.  To date no positive WNV site has tested positive after intensive post occurrence larviciding and site specific targeted fogging.

As with our response to the initial positive WNV site the other 3 positives were treated similarly when terrain allowed. All sites have become WNV negative in post-positive trapping and continue to be so.

Of concern were a farm the just east of Paonia and a marsh area downhill and below a local organic farm.  Both have certified organic status or organic food/events associated with their livelihood, limiting the product choices and adulticide spraying.

At one, intensive larviciding and physical mitigation on the property did not keep down rising numbers of mosquitoes, particularly Culex. After several episodes of the entire crew combing the area treating every location with aggressive larval products, the trap counts continued to rise.  A knockdown adulticide spray would have been used in a targeted fashion, but as an organic adulticide was not yet available, we watched numbers climb towards the point of no return.

Since the source of the mosquitoes was not on organic farm’s land, an off-site trap was placed in an attempt to locate the source of the  rising population of culex. Despite finding no resident larvae in the marsh/pond, a RAMP reader positive allowed us to fog an area far enough away from the organic farm and not endanger their certification. Due to this treatment, the population of mosquitoes at the farm has markedly declined, literally plummeting and remains low to date. This site and the organicfarm itself continue to be monitored closely.

Another B& B farm was a similar issue; organic produce, and additionally a clientele sensitive to the appearance of NFMAD personnel appearing and using machinery to treat the area with some sort of substances. The owner was contacted and informed of the situation by Glenn Austin and myself.

I discussed the issues involved and options for treatment. The garden was avoided as were any contributing water sources. All outdoor areas were barrier sprayed with an organic product, as were the perimeters of the buildings on the property. Then all possible contributing mosquito sources and habitat were fogged with low drift hand foggers to knock down the adult population, as truck fogging was not possible or desired.

As with any site showing high trap counts, prior larviciding was augmented with a thorough search and treat technique. To date WNV has not reoccurred, however numbers of mosquitoes have not declined as dramatically as has occurred at other sites where truck fogging was done. A different technique of backpack spraying using a dilute adulticide solution will be performed by the time of the August meeting.

The numbers of adult mosquitoes along south Midway continue to alternate between high and low in the traps, despite full phased treatments. Post-spray trapping drops significantly, then rising again within 5-7 days if the weather is hot, particularly with rain showers.

The entire Midway area is an ongoing complex issue that includes large amounts of river frontage, hard to maintain irrigated fields, and poor accessibility. In the future, NFMAD acquiring an ATV is a necessity to make a dent in the mid-late season emergence of large numbers of adults. Hotchkiss and its surrounding areas have largely been kept under control with the same type of full phased larval and adult treatments, with the HUGE addition of the ATV mounted sprayer, graciously run by Zach Hotchkiss on his own side by side John Deere.  Zach has been instrumental for true mosquito control this season, and we have deep gratitude for all his donated time, energy, and equipment.

Without an ATV, Midway properties must be truck fogged, so the mechanical issues that plagued early to mid-July caused a lot of frustration for the area residents as well as the crew.  Once the truck units were reliably fixed, trap counts have dropped all over Midway as the crew has been able to target adult knockdowns.

Although less populated, north Midway has the same issues, and undeniably contributes to south Midway’s problems, and both areas most likely contribute to Paonia and/or Hotchkiss town mosquitoes.

North Midway fields and river frontage do present a much larger area to treat, dramatically eating up crew time and product to achieve full coverage of the territory.  If areas are overlooked, or if treatment is delayed, then a hatch of adults could be huge. It is here that truck and ATV spraying is most effective and needed as an integral part of mosquito control planning. The combination of both types of equipment is the most efficient use of time, money, and product, and does yield the best outcome.

These are areas that would most benefit from aggressive physical mitigation with backhoe or trackhoe equipment, continued owner maintenance through the season, guidance of the crew by the owner to help direct product application, and vigilance in seeking temporary breeding sites that result from rainy weather and/or irrigation.  The rewards of this type of full scale mosquito control for the entire Midway area would give the highest return for the entire District, and must be given additional consideration for budget planning and outside funding.

July was a trial by fire for the members of the field crews, learning the use and value of the various new products and machinery while also dealing with the quirks of poorly maintained old equipment. Add to this the necessity of full scale site mapping/evaluation, learning the evolution of the season with regard to declining and emerging mosquito breeding sites, while continuing to monitor and treat hotspots, and the true nature of dedication can be observed in the field crew!

We have responded to every voice mail call and requests from people stopping us on the streets. We have tried to source out every speck of possible breeding site in areas of high trap numbers and/or WNV positive trap pools. We have searched extensively for areas where adult mosquitoes are coming from, moving far beyond known spots from previous years, and checking well outside the District boundaries.  We have worked many split shifts, far into darkness to apply products effectively reducing impact on predator species and bees.  We have accomplished effective event prep for parks and community meeting places, including the County Fairgrounds.

Overall I feel in July we have done well, perhaps not everywhere, although currently I feel that is somewhat unrealistic. But, as I was told by someone who stopped me on the street to thank me, ” There are still mosquitoes, but know they could have been a lot worse.” Indeed.

August so far seems as if it is off to a slow start, perhaps this season is beginning to taper off. Or it could pick up speed again. Or? Obviously the weather plays a big part in the length of the season, and nightly temps have already cooled down quite a bit.

Full time and full phased mosquito control, including trapping, will continue throughout the month of August, and the Labor Day weekend holidays in early September.  At this point, we do not know how far the actual season will extend into September but the Board planning does include September just in case the season is extended.

The focus of effort is now turning to the District’s schools as the 2013/2014 school year begins in just a couple of weeks.  We are acutely aware of the vulnerability of students participating in sports that start practicing early on in August, wearing shorts, and have already begun coordinating physical mitigation around playing fields.  There are unique issues with targeted spraying from a legal viewpoint for school playing fields and playgrounds, and we are actively considering all the options for safety and protection from mosquito-borne illness and pesticide exposure.

In anticipation of overwintering mosquitoes that come out of hibernation in early spring, hotspot areas will continue to be monitored past the first freezing temperatures, and an adult knockdown may be needed in late September or early October.  The product inventory and budget planning do already include this possibility, particularly because overwintered mosquitoes can still make you sick.




Just a heads-up to people in the Crawford area or if you have friends and family in Crawford Country. I (Tom) was told last night at the Crawford Town Council that a Crawford woman is the second confirmed WNV case in the county and she is certain she contracted it from bites received either at Crawford Reservoir or Gould Reservoir. So avoid the evening hours if you go fishing or wear good covering clothing and use a good repellent.
Due to high trap counts and other threshold variables, the following areas will be target sprayed in very specific areas with adulticide tonight between dusk and dark, 8/8/13, weather permitting. If the weather doesn’t cooperate (winds and/or rain) then we will reschedule for tomorrow :

Paonia area: Bell Creek Road. Also the Campbell Ranch property.

Bowie: A specific area at Bowie will also be treated.

As always any residence within 200 feet of the events have been notified. If you are concerned about exposure in these areas please shut off swamp coolers and close windows and remain inside until a half hour after the truck passes. The fogging truck will make a first pass and honk it’s horn while doing so. During the second pass the truck will be spraying. Please note that the foggers have a radar attachment that regulates the amount of product according to the speed, no matter the speed the output is the same.

Please be aware that West Nile Virus has been found in the Valley and take appropriate precautions if you are out in the evening hours. Long sleeves and repellent. PLEASE recheck your yards for standing water. The season is helping but one mosquito can lay as many as 150 eggs. That’s too many new neighbors!

Finally, be aware that about 95% of what NFMAD does is never “announced” including: mitigation, larvaciding, and of course public education. Adulticiding is a small, but important, part of our program. Thanks for your support!


NFMAD Notice: the following areas will be target sprayed in very specific areas with adulticide tonight between dusk and dark, 8/7/13, weather permitting. If the weather doesn’t cooperate (winds and/or rain) then we will reschedule for tomorrow :

Hotchkiss area: Zack’s BBQ and the field on the east side of the Delta County Fairgrounds.


Due to weather, the Fairgrounds truck fog may be delayed until Sunday night, 8/4/13 if not possible after dusk tonight.

Due to high trap counts and other threshold variables, the following areas will be target sprayed in very specific areas with adulticide tonight between dusk and dark, 7/31/13, weather permitting. If the weather doesn’t cooperate (winds and/or rain) then we will reschedule for tomorrow :

Hotchkiss area: Hanson Mesa Road from the railroad crossing to the top of the hill. Coal Road north to Shifflet addition (Elm) turnoff. Cedar Street from Sheppard’s Lane to the south edge of Willow Heights Park. Also an area along the river including the old sewer ponds will also be sprayed.

The Delta County Fairgrounds will receive a deep-cleaning, truck fog on Saturday night in preparation for the Fair with a touchup before the big events of Thursday – Saturday, 8-10.

Paonia area: Lamborn Mesa Road in the 4100 Road intersection area. Also the Campbell Ranch property to the west.

Bowie: A specific area at Bowie will also be treated.

As always any residence within 200 feet of the events have been notified in person and a door hanger left if no one was home. If you are concerned about exposure in these areas please shut off swamp coolers and close windows and remain inside until a half hour after the truck passes. Please be aware that West Nile Virus has been found in the Valley and take appropriate precautions if you are out in the evening hours. Long sleeves and repellent.

West Nile Positives: An Update

There were several positive trap pools in the last week in the District, including lower Mn. Creek area, and the Lamborn Mesa area.

Two other trap pools tested positive in remote locations, and have been treated with all phases of product control and physical mitigation, including spraying with adulticide using hand held units. These two areas are more than half a mile from any resident of the District, however Chris and crew found swampy, marshy breeding areas that were possibly feeding several farms and residential areas. One of these sites actually required the crew to backpack the product a long distance.

Chris and the crew surround the trap site and fan out for a half mile or more in all directions whenever there is a positive trap pool on the RAMP reader, visiting with or leaving a door hanger warning residents that WNV positive adult mosquitoes have been found in the area, as well as searching and treating with larval products for every last puddle that could possibly be breeding mosquitoes. Target spraying is scheduled if indicated, and a tight trap perimeter is set to help direct the search for the source of the adult mosquitoes.

The Lamborn Mesa site, the first positive in the District in a denser residential area, has now tested negative on RAMP for 2 full cycles of perimeter trapping. Many new areas were mapped and treated, and all affected residents within .75 miles were personally contacted and their properties evaluated and treated. The crew fanned out another half mile and widened the trap perimeter, and found an additional positive trap pool over one mile away, so again, the entire encapsulation process has occurred. Happily, that area is now testing negative on RAMP.

Aggressive treatment continues at the lower Mn. Creek area positive trap site, with multiple traps testing negative, and the “search and destroy” mission uncovering many hidden breeding areas. The crew has been amazing…dedicated, willing to crawl, climb, and haul product into places not accessible by vehicle or simple walking. Drainage has been followed for long distances, and treated heavily. This approach is definitely paying off in decreasing the adult mosquito load, while adding to the ongoing maps of the District.

Comprehensive larval treatment is occurring in all areas of the District, with targeted adulticide spraying using the ATV and hand held backpack units or the truck fogger when necessary. We have had multiple issues with the truck foggers over the last 2 weeks, which have hopefully now been resolved with the support of many residents and the crew, Lee Owsley and Chris Tschinkel in particular. Thank you to all!

The immediate responses to trap positives would not be possible without the RAMP reader!

Once again, a huge thank you to all the donors that made purchase of the RAMP reader unit possible.

Recent Colorado W. Nile news listed Larimer county with over 50 positive mosquito pools on PCR testing, Boulder County with 35, and others with high numbers, on down to Delta County with 4 positive pools. Boulder and Longmont have initiated weekly truck fogging as the positive pools are widespread through out the county in highly populated areas. This is the first time in many years that Boulder county has initiated a fogging program, and this is directly as a result of the CDC declaring an epidemic in the US, with Colorado having horrible levels of illness in 2012.

For the NFMAD, having the ability to test and respond rapidly, rather than the PCR testing wait of up to 12 days, is truly revolutionizing the District’s operations plan, while making every budget dollar count. We are continuing to RAMP test every trap pool that has a single culex mosquito present as we strive to eradicate West Nile virus in this District. Two of the positive trap pools that have occurred in the District had a very low count of total culex mosquitoes, and total overall. Despite the cost of running tests on each trap pool, this information is vital to killing off the adults hopefully before infected culex can lay eggs and/or go through an entire cycle of hatching in as little as 5 days in the hot part of the summer. And we are definitely in the hot part of the summer!





Due to high trap counts and other threshold variables, the following areas will be target sprayed with adulticide tonight, 7/30/13, weather permitting:
Areas of Lund Rd., Coburn Rd., and Bell Creek Rd.


Whoa! Wind, thunder, lightning, and 20 feet of flying cottonwood tree derails target spraying until tomorrow night!

Due to high trap counts and other threshold variables, the following areas will be target sprayed with adulticide tonight, 7/29/13, weather permitting:
Areas of Lund Rd., Coburn Rd., and Bell Creek Rd.





Due to high trap counts and other threshold variables, a targeted spray will occur at Zack’s BBQ in Hotchkiss tonight, July 28, 2013, weather permitting.  Please clear the area by 10 pm. Thank you.


July 25, 2013
On July 15, 2013 there was an illegal fogging in the town of Hotchkiss according to two eyewitnesses that contacted the NFMAD board today.

A truck spraying adulticide, probably malathion from the odor, was seen driving on Cedar Drive up past Willow Heights Park, Coal Rd., and possibly elsewhere in the town of Hotchkiss, with the sprayer active. The sound of a truck mounted spray unit is very distinctive, and was heard by more than one resident.

There is some discrepancy on who was seen driving the truck and doing an illegal application of an organophosphate adulticide. NFMAD is investigating further. Please contact a board member if you have any information regarding this incident.

Adulticide fogging MUST be done in a strictly controlled manner, observing wind direction, wind speed, temperature, humidity, and other factors, as well as using appropriate product for the terrain, and observing organic agriculture and pesticide sensitive residents with posted land.

Much of Cedar Drive is posted as “pesticide sensitive”

Rogue fogging is blatantly illegal in the US, as a result of uncontrolled pesticide discharge into the environment, as well as endangering immune suppressed residents, children, and the elderly.

NFMAD is doing targeted applications of adulticide when indicated by trap evidence and other threshold variables is strict compliance with all rules, regulations, and laws, on laser droplet tested/calibrated equipment. This is not the same as driving a truck up and down streets fogging!

If you are experiencing a lot of adult mosquitoes, please, please, call the NFMAD 527-6681 telephone rather than deciding to spray the towns.




Former board member Rosemary Bilchak had some questions and concerns about NFMAD’s 2013 operations, expressed in the letter below.  We have published Rosemary’s letter and the Board’s response here to help dispel some rumors and misunderstandings that seem to be happening in the District.  If you have questions, please either visit the NFMAD Facebook page, or call the District telephone at 527-6681.

Thank you


Rosemary and Gordon,

We have received your email comment letter, and the NFMAD board responses are written below.  It is unfortunate that you feel betrayed by the NFMAD operations plan for 2013, however, in a state of epidemic

W. Nile virus as declared by the federal CDC, the 2012 operations plan would be insufficient to comply with state and federal mandates of mosquito control, as well as establish safety from West Nile viral infection for the residents of the District, as evidenced by the widespread positive PCR testing of mosquito trap pools and the high incidence of W. Nile illness in the District during the 2012 season.   Our current Operations plan is necessary due to the high level of vector abundance and widespread viral saturation that was allowed to develop prior to the 2013 season.


First of all, there have not been claims that all products including larvicides, are “safe and organic” or registered for use on organic farms.  There is a new product coming on the market this week called Essentria All-Purpose, that is registered for organic crops, the first of its kind.  Please refer to the product labels and MSDS posted on the website under Procedure Manual for the product information currently in use by NFMAD.  Mavrik Perimeter barrier spray does not kill bees and other predator species if appropriately applied after dark when foraging is not occurring.


Further, at the June NFMAD board meeting, the following information is in the minutes regarding Mavrik as a barrier spray product:


“A program of offering barrier spray treatments of small area for a fee was presented. A product called Mavrik will be used. The product is applied to foliage and is harmless to bees when dry, despite containing small amounts of permethrin. The product lasts for 3-4 weeks in shaded areas, but will begin to break down in one week if applied to full sun areas. The cost will be $38 for NFMAD District residents and $58 for nearby non-residents. Resident may subscribe to monthly applications at a discounted rate. All applications will be by appointment and must be pre-paid. “


At no time was Mavrik Perimeter presented as an “organic” product.


We have not made a single application of any barrier product or adulticide during daylight hours when predator species, particularly bees are foraging or even present.  Your observations of a decrease in butterflies, dragon and damsel flies, ladybugs, bees, etc., have not been supported by reports throughout the District where adulticide has been target sprayed.  On the contrary, predator species are here in great numbers, and we have received favorable reports from over a dozen organic home and market farmers and businesses of the success of limited spraying and barrier product applications.


The board, field manager and crew are well aware of the differences in the various categories of pyrethroids, and other products.  Thank you for the links, and some of those sources are excellent. We have previously reviewed all the information available on the TedX site, and frankly, our purchase of the ATV mounted sprayer and the two hand held units was directly influenced by the desire to minimize environmental impact and exposure to non-target species, including beneficial predators.


Advance notification of adulticide spraying is occurring on the ( website “News” page, the Facebook page, the Paonia message board, and the Hotchkiss message board, as well as to individual residences within 200 feet of the treatment area, not property lines.

Every effort is being made to respect organic agriculture and bee hive locations, and pesticide sensitive residents that have provided the District with the appropriate state paperwork and a boundary map of their property, while also controlling the adult mosquito population and breaking epidemic West Nile virus.


NFMAD is actively participating with the Colorado Department of Agriculture program, “DriftWatch Pesticide Sensitive Viewer”, which is a new program compiling organic agriculture of greater than one half acre, bee hives, registered wetlands or other sensitive environments.


A quote for DriftWatch:


“Some of the sensitive crop areas, or data layers, that CDA intends to register in Colorado include beehives, certified organic crops, fruits, grapes, nursery crops, pumpkins, melons, tomatoes and vegetables. The Department will review and consider adding additional sensitive sites upon request by growers or applicators.”


Many volunteer hours have been logged mapping Delta county locations that fit the parameters of this program in an effort to protect our farms, ranches, fields, rivers, and other District areas.  DriftWatch does not register private homes, or pesticide sensitive individuals, as that is a separate registry requiring filing of forms and paperwork.


Although your parcel numbers were sent in an email, the copies of the Pesticide Registration paperwork for Gordon were not given to NFMAD by mail, email attachment, drop-off, or fax, despite requests made in person at the June board meeting, by telephone and email, by Rain Klepper and Chris Tschinkel for both the copies and a map clearly labeled with name, address, telephone numbers, email, and the closest intersection to the street address and residence.  This information was also posted on the aforementioned places online for the entire District on June 14, 2013, and repeated last week, in NFMAD’s effort to map organic agriculture and pesticide sensitive residents.  In addition, many organic farms and VOGA members have been contacted by telephone and email to add their agricultural pursuits to the map.


Despite your failure to provide the District with the pertinent information, out of respect for the service in previous years that you have both volunteered to the District, Rain and Chris spent a considerable amount of time researching your property boundaries through the Delta County offices, then posting hot pink laminated “pesticide sensitive” signage on Cedar Drive to assist the crew in recognition of your property line.  The treated area on mid-Cedar Drive were cattails  well off the road, through handheld application.  Your property line was not sprayed, however it would assist the mosquito control efforts if the ditch was cleaned out of trash and cattails that is on your property along the left hand side of the road.


Personal notification has not and will not be made to your residence as there has not been any adulticide product application from the ATV or truck sprayers within 200 feet of your home.  Pesticide registry requirements do not include a buffer zone of 200 feet from property lines, nor are railway or road setbacks included.   Schools are excluded from all pesticide spraying except parking lots, and NFMAD is in full compliance with this requirement.


The following quote is from the State of Colorado Pesticide Registry Information:


“If you don’t want your property included in the spraying, you must contact those people and ask them to exclude your property from the program IF they are able to do that.

Any notification provided to the public during a Public Health Pest Control operation (i.e.: mosquito treatment applications) by municipalities and/or commercial applicators, is done as a courtesy to those requesting, not because it is a state law requirement.”



NFMAD has recently been informed that this is the only District in the state of Colorado that is giving notification of adulticide spraying, including targeted applications.  We have every intention of continuing to notify the residents.


In addition, your civil lawsuit with the Hopper’s precludes pesticide drift from their property onto your property, but does not extend to other neighbors, the town of Hotchkiss, or the NFMAD. On Friday, June 26, 2013, a Mavrik Perimeter barrier spray was applied to the Hopper’s grass 50 feet from your property line.  The equipment used was a small handheld unit, operated by Chris Tschinkel with an effective drift of one half foot, or six inches.  There was no pesticide drift onto your property or approaching your property line. If you are smelling pesticides, it is not the Mavrik Perimeter product which is virtually odorless.


On July 15, 2013, Zach Hotchkiss applied Perm-X to an area on private land of Hummingbird ranch (Mindy Bell), and Johnny Hotchkiss’ south of the Bell property.  Both of these areas of application were more than 200 feet from the individual’s property line with neighbors.  Your lands do not abut, nor is any part of the inner town public area within that zone.  Hence, my email response that spraying was not happening inside the town of Hotchkiss.  Zach was not running the sprayer while putting gas in the ATV. If you were walking by these properties and heard the ATV sprayer, that is impressive.  However, NFMAD cannot state that another resident was not spraying, nor do we have a listing of every privately owned piece of equipment.  Your accusation that Zach Hotchkiss is spraying “his friends” is unfounded, false, and frankly, unfair.



Your assertion that notification is not and was not posted on the website or Facebook page is false.  We have also been advised that given the epidemic status of W. Nile viral infection determined by the CDC, the NFMAD policy of notification as stated on the website is far above and beyond the legal requirements, and is not taking place in other districts due to budget and personnel restrictions. Rosemary and Gordon, of all people in the District, you should understand the limitations the District has to work with.  NFMAD will continue to notify in general terms for private land, and more specific terms for public areas such as the Delta County Fairgrounds.  Personal notification is only occurring if the treatment areas come within 200 feet of residences, and then only to affected residents.  Personal visits and notifications are also occurring within concentric perimeters from any trap pools that test positive on the RAMP reader for presence of WNV.    These positive trap pools are also posted on the aforementioned online pages, and forwarded to KVNF, Ken Nordstrom at the Department of Public Health, County Commissioner Mark Roeber, Delta Mosquito District #1, as well as Tom Wills for dispersal to the newspapers and online media.


Notification has been posted in these places, and then copied to the town message boards, with the general areas to be included on the following dates, with the addition of posting if postponement due to weather or other factors happens, when possible:












In paragraphs 17-21, you once again display a complete lack of understanding of the NFMAD Operations plan and focus. The District in no way has abandoned a larval control program, in actuality all evidence points to our current larval control program as being considerably more effective than in previous years.  The aggressive physical mitigation by both NFMAD and various District entities both public and private using backhoes, trackhoes, shovel crews, and crew hours of combing the terrain, have far exceeded any terrain or larval mitigation efforts previously done in this District.


In addition, doubling the trap sites, the use of trapping perimeters, and RAMP testing has revolutionized the ability to rapidly identify and target breeding habitat and adult resting areas, and has significantly decreased the incidence of positive culex mosquitoes in the trap pools.


Despite all these successes, some adult mosquitoes of all species do hatch.  Despite the enormous amount of larval products applied, adults do hatch.  This may be a site we have not found, or a private residence that has not kept up with policing their own property, or any number of other factors in a 50 square mile District.  Seriously, the data cards had not been updated for over 3 years, by Biz’s own admission.  NFMAD started in March surveying each and every grid, and every red circled identified hotspot for possible physical mitigation, and the type of product that would match the terrain when and if larvae appeared. The current grid maps of the District now look completely different, and will support effective physical mitigation in the coming 2014 late winter/early spring seasons.  These maps have also aided NFMAD’s ability to begin writing for grant and other financial assistance to accomplish physical mitigation projects that are well beyond the capacity of the District budget, with an eye towards the eradication of West Nile virus incidence completely over two years.  This is exactly what the districts in Utah with similar terrain accomplished in two years, using this exact same plan.


When adult numbers of mosquitoes pass CDC mandated thresholds, yes, the plan is to use targeted, specific applications of adulticides, in full compliance with local, state, and federal regulations for a state of epidemic.  We understand that the 2012 NFMAD board’s opinion was that an adulticide should never be used under any circumstances, even in a stated public health crisis of epidemic, as evidenced by the program in 2012 in the District.


As a result of the previous board policy of “no spray ever”, the District is now dealing with governmental oversight because of discrepancies seen between the 2012  reported trap data and that collected by Public Health officials acting independently.  In addition, the high level of positive trap pools for West Nile virus on PCR testing, triggered reporting from the Colorado Department of Public Health and Environment agency to the CDC.


The District is being very closely monitored, verification trapped, and other activities from the state and federal governments that are unknown as to date and location.  If NFMAD allows adult mosquito numbers in traps to rise past mandated thresholds, without action in the form of adulticide application, a report is sent to the state, and then to the federal government. If this happens multiples times, control of the District, including choice of products, equipment, frequency and location of application, etc. will be taken away from the board, and the District will be disbanded.  We are absolutely fighting with everything we’ve got to avoid the total catastrophe of governmental control.  One aerial spray event is all it takes to lose organic certification for our valley.


You state confusion about the Merchant Herald article and also the statements of support made by Ken Nordstrom.  Ken was trying to quell the protest mounted by NFMAD at the proposal of aerial fogging for Delta District #1, Cedaredge, Olathe, and several other areas close to the town of Delta, and at the same time to clarify an unclear email.  Ken’s actual statement was that the District would never be aerial fogged unless an emergency health crisis justified the action, and would only take place with the “full knowledge and support of the NFMAD board of directors.”  The full quotation is very important in this instance.  The mapping of organic agriculture is supporting our case with the state and federal agencies that NFMAD has the District under close surveillance and a full phased response program.  The local county government is not confused as to the financial devastation of the North Fork that would occur with an aerial event, however the federal and state government agencies trump the county agency, which in turn has control over the NFMAD.  All of these governmental agencies trump individual agendas and ideologies.


If NFMAD did not mount an appropriate and full phased mosquito control operation, the state and federal governments can absolutely overrule county and local entities, hence Rain’s post on the website:


“the June 14 entry on the News page of the website, that there exists a clear and present danger that “the District could be aerial sprayed regardless of our operations plan and local thresholds, and despite all protests”



The State and Federal epidemic crisis plan is blanket/ground twice weekly fogging of the entire District to back up aerial fogging. We are absolutely committed to avoiding control over our health and valley being taken away, particularly given that pesticide sensitive registry and organic certification is not considered in a state of epidemic when declared by the federal government. Yes, NFMAD is spraying adulticide in the most targeted, specific, low exposure methods possible to contain adults below the mandated thresholds, while doing everything possible to mitigate the mosquito threat BEFORE adults hatch and fly.



In paragraph 2, you accuse Rain of lying about the fact that no fogging, as of July 16th, had happened in the towns of Paonia and Hotchkiss, by changing the wording to “within the District”, rather than “within the towns”. Again, the direct quote is significant.



Your request to be personally informed of every application of larval, pupal, barrier, and adulticide product within the entire District is not possible or reasonable during the height of mosquito season. All of these records will be available to the state or a supervised viewing by a resident in the fall.  NFMAD is in full compliance with the Colorado Open Records Act, and public records may be viewed online for trapping, financial transparency, operations updates, etc.   We must protect resident privacy, and the information you are demanding would compromise this.


We understand your anxiety about pesticide exposure, particularly for Gordon or other immune-suppressed residents.  We obviously have a difference of opinion on the relative risks of West Nile epidemic infection, aerial and blanket ground fogging, and the loss of NFMAD control vs.  the judicious use of targeted spraying of adulticides.  Please consider subscribing to the FaceBook page, or the message boards for posts of notification on where and when targeted spraying will occur so that you may avoid unwarranted exposure.

Below is Rosemary Bilchak’s email letter of 7/24/13 sent to Rain Klepper’s private email, with the board response letter above:

Hi Rain,


The primary reason for my resigning from the board was to be able to help my husband to rescue his health. My resignation most certainly was not with the intent to enable the board to return to policies and practices that jeopardize the health of our community, and particularly my husband’s health. I am feeling betrayed.


Rain, I really need your help  in understanding a few things, such as:  Where were the advance notices of adulticide application?  How is the claim in your email that there has been no fogging in the district this season not inconsistent with your July 6th article in the Merchant Herald describing “several instances”, by the time of the article, of late-evening application of adulticide by Zach Hotchkiss at the old sewer plant and the fairgrounds, and adulticide applied in Willow Heights Park and Volunteer Park?  Why is NFMAD claiming its fogging and barrier spray products are “safe” and “organic”?  Meanwhile, does the board not consider the dramatic decrease in natural predators of mosquitoes an “adverse incident” of adulticide application?  How can we reconcile your claims of a threat of aerial spraying, with your Merchant Herald article?  Who was fogging in Hotchkiss on the 15th?


Who was fogging on the night of July 15th?

Let’s start with the easy one.  In reference to your email response below, I am sure you know better than to suggest that I do not know the sound of a fogger.  And unless the district has contracted with outside pesticide applicators, there simply are not that many fogger machines in the district.  If Zach were out getting gas for his ATV, there would have been no reason to turn the fogger ON.  Yet, it was in the spray mode (as opposed to the idle mode) on the night of the 15th.  Hopper’s fogger was parked in his front yard the entire time, so it was not his machine making that noise, and I know of no other foggers of that caliber in this area.  Is it possible that Zach is doing a little “extra” fogging for his friends? If not, then who was fogging that night?


Claims that NFMAD pesticides are “safe” and “organic”

Recently I have heard multiple times that NFMAD is telling the public that the chemicals in use for barrier spraying and fogging are “safe” and “organic”. When Mike Heck was on the board, he confused the synthetic pyrethroids with the organic pyrethrins.  Are there district personnel who are still confused?  Or has the district switched from using the pyrethroid Permethrin to pyrethrum?


From the posted invoice, NFMAD is still using Prem-X 4-4, which contains Permethrin, and the toxic synergist piperonyl butoxide.  Agnique WSP contains POE isooctadecanol, another substance not allowed in organic production.  When asked at the board meeting what was being used as a barrier spray, you responded, “Mavrik,” which is another synthetic pyrethroid, and an adulticide.


If you need to educate some of your personnel as to the toxicity and documented hazards of pyrethroids, you may find these links helpful:


Also, you can explain to them that if any synthetic pyerthroids such as Permethrin, were allowed in organic agriculture, the Organic Food Production Act (OFPA) of 1990, Sec. 2105, states that they would have to be included in the National List of Allowed and Prohibited Substances:

“To be sold or labeled as an organically produced agricultural product under this title an agricultural product shall–
(1)have been produced and handled without the use of synthetic chemicals, except as otherwise provided in the title;”

but, as you can confirm, they are not in that list.
If pyrethroids were allowed in organic production, they would also be included in the searchable database managed by The National Organic Standards Board (NOSB), which is found on the Organic Materials Review Institute’s (OMRI) website.  Not there, either.


While it is understandable that some in the public may be confused by these two groups of pesticides, it is not acceptable that NFMAD personnel are confused, or that they promote that confusion. They need to understand that synthetic pyrethroids are more stable than natural pyrethrin, which is metabolized too readily to be effective on its own; and synthetic pyrethroids are chemically engineered to be more toxic than natural pyrethrins, through the use of a synergist, piperonyl butoxide (PBO), which is a highly toxic pesticide and has documented effects on human neurodevelopment.  Here’s a link you can show them:


Notice of adulticide applications and sensitive areas

We keep hearing from the meetings and website and articles and email, that notice of any adulticide applications will be given.  Yet, we have received no calls for the adulticiding that has occurred in our neighborhood.  Nor has notice been posted on the website.  To date, the only notice I have found on the website or Facebook, appeared there AFTER I called and complained.


I provided our parcel numbers early in the season so that NFMAD would be cognizant of our property boundaries.  Yet, last Thursday, we barely missed being targeted with toxic sprays.  To add insult to injury, the NFMAD NEWS tab stated that fogging would be done the following day, including:


Eastern side of Cedar Drive, (spray will be 150 feet away from the following Cedar Drive westerly right of way/Bilchak property line: from Railroad tracks to 170 feet south of Shepherd’s Lane), then the ATV will continue to North of Shepherd’s Lane to Hotchkiss’ property.


Excuse me, but how did the crew manage to keep the spray 150 feet away from our property when our property line lies to the east of Cedar road, just behind the town hall, and then runs directly under Cedar road?  To be 150 feet beyond that would require climbing a hill that even an ATV could not attempt.


This was not the first time that adulticiding was done close enough to contaminate our property.  The Hopper’s yard was sprayed on Friday, June 26.  If you look at our parcel map, it is obvious that anywhere in his yard is well within 200’ of our property.  Yet we received no notice.  Given that NFMAD is using a synthetic pyrethroid for its barrier application, this is not acceptable.


Threat of aerial fogging?

How is the statement in your Merchant Herald article, that “Ken Nordstrom confirmed that aerial fogging will not take place without the full knowledge and support of the NFMAD board of directors” not inconsistent with the statement in the June 14 entry on the News page of the website, that there exists a clear and present danger that “the District could be aerial sprayed regardless of our operations plan and local thresholds, and despite all protests”?  Besides, how can the alleged threat of imposed aerial fogging be considered legitimate, when the same Merchant Herald article admits that aerial fogging programs are being abandoned in other counties, due in part to “lack of effective adult control and kill rate”?  Then, even if someone truly believes that aerial fogging is justified, what entity has the money in its budget for aerial fogging?


Request for information

With Gordon’s immuno-compromised condition and our sensitivity to exposure to pesticides, I’m sure you can understand our need to know where these pesticides are going to be or have been applied so that we can avoid contact, as best we can.  We live in Hotchkiss, and walk and shop and spend idle time in Hotchkiss and Paonia.  Consequently, we feel that it is not sufficient to receive notice only when an event is happening within 200’ of our property.  It is imperative that we know when any application of pesticides, adulticide or barrier, is occurring anywhere within the District.  This expectation could be met by following through on NFMAD’s stated objective of posting notice on the website; however, we want to be notified personally whenever there is an adulticide or barrier application happening within Hotchkiss.  24-hr notice should be sufficient.


There are some data items which NFMAD’s Pesticide Discharge Management Plan says must be kept for all treatment activities, that would be very helpful to me.  Please tell me how I can get the following information for each application of adulticide this season:  Date, time, location and size of area treated (with map, if available), name and quantity of each pesticide product used, description of pest management measures implemented prior to adulticiding (with map, if available), justification for using adulticide, and before and after trap counts for the treated area.


Please also tell me when and where I may examine the records of the larvicide applications for this season.


The management plan additionally states that there is an assessment of effects of pesticide application on non-targeted organisms.   We have noticed a dearth of butterflies, dragonflies, mayflies, etc., which are normally abundant in our yard.  In fact, I have not seen a single dragonfly since our return from Gordon’s cancer trial at NIH in June.  There is documentation that these beneficial species account for killing a large percentage of mosquito larvae.  I don’t recall the actual number, but it was possibly as high as 80%.  The oil that NFMAD is applying to breeding sites is not mosquito-specific.


I am afraid that all of the adulticide spraying coupled with the application of oils is killing off beneficial non-targeted species that act as mosquito predators.  NFMAD is effectively killing its allies and has set the course for this season:  We can predict with assurance that the mosquito populations are going to increase.


Bottom line

To summarize, we are part of the public that is dismayed that the focus has turned from larval control to adulticiding, that the approach adopted by NFMAD is killing off beneficial species, and that the information coming from NFMAD is misleading and self-contradictory, including claims that the adulticides used are safe and organic.


If the reports of the mitigation projects are true, then I applaud your success in that realm.  That alone should reduce mosquito populations permanently.  I would like to support your efforts in the other areas as well, but I’m afraid that I have not seen the justification for many of the actions taken by this board, which appears to be reverting to policies that create a significant hazard to public health, and particularly to the health of people with compromised immune systems, one of whom is very near and dear to me.


I’m sure you can understand our anxiety about exposure.  I look forward to hearing from you and getting the data I seek.

Hi Rosemary,

There were several barrier applications in the lower South Hotchkiss area, nothing within 200 feet of residences or other property, but no adulticide sprayed by NFMAD.  There hasn’t been an adulticide application within the towns of Paonia or Hotchkiss this season, so if you saw fogging, it was private application by a resident or other person.  If the need arises, of course notification will be given on the website, Facebook page, and door to door to affected residents.  Also, KVNF will do notices of comprehensive fogging in the towns, although at this time there is no scheduled plan to do so.  Zach Hotchkiss was out on his ATV with the sprayer mounted on it getting gas at Master’s, but was not spraying product.

take care,

Rain Klepper

Subject: Fogging in Hotchkiss

There was fogging in Hotchkiss last night. I looked on the website and Facebook and found no notice of this event.  Was this done by NFMAD?  If so, could you please send me the post-spray data you keep for NPDES or tell me where it is posted?  We are quite concerned as we walk through town often and need to know where pesticides have been applied.

Thank you.







NFMAD has discovered in the last 2 weeks that we are the only District in Colorado that gives notification on spraying adulticide!

There are a few notices if aerial fogging will take place, generally only at the beginning of a series.

This is more than a little shocking, yet totally within the legal boundaries of mosquito control, and many Districts simply post a statement that notification is beyond the “personnel and budget capacities while also fighting a viral epidemic that can be fatal”.

Ok, while I can understand the overwhelm on the mosquito-sized budget and hardworking crews, really???? We have every intention of continuing to notify our residents of even small targeted adulticide spray areas to the best of our ability, and truly hope other Districts will follow this example of open communication with their public.

So be warned: if you live outside the NFMAD, don’t depend on your local mosquito control to inform the public of fogging or other product applications.

Even if you are registered as “pesticide sensitive” with the state of Colorado, since the CDC declared an epidemic of West Nile virus, applications of pesticides can still be legally used on your property if you are given notification.

Bottom line: if you live or work outside of the District boundaries, it may take some effort and research to fully protect yourself and your family from pesticide exposure.

A Story of Recovering from West Nile Virus In Texas




NFMAD Board at work. April 2013

NFMAD Board at work.
April 2013







A mosquito trap pool has tested positive for West Nile virus in the area of Minnesota Creek drainage closer to the easterly edge of the town of Paonia on the RAMP reader.

Chris and the entire crew have combed an area up to 3/4 of a mile from the trap site, informing residents while searching and treating any breeding areas found. A trap perimeter is in progress.

The two previous trap pools that tested positive in the Lamborn Mesa Rd. area and Bowie area have been successfully contained with aggressive full-phased treatment up to one mile in perimeter. There have now been 2 subsequent multi-trap checks of the areas that have tested negative on RAMP.

The purchase of the RAMP reader this season has definitely given the District the ability to rapidly respond to W. Nile positive trap pools, rather than waiting for up to 12 days for a grouped test pool to make a round trip to Denver. A huge thank you once again to all the towns and private donors!


Due to mechanical difficulties and weather issues, the notification list of 7/20 was not fully accomplished and areas that were not sprayed have been added to the list for 7/23 or 7/24.


Either tonight, 7/23/13, or tomorrow night, 7/24/13, weather permitting,  the following areas will be target-sprayed due to high trap counts, and/or other threshold variables:

In Hotchkiss/South Midway:

Zack’s BBQ

Old Sewer Treatment

Delta County Fairgrounds

Areas of Riverside Road

Areas of Coal Rd.

Hummingbird Ranch, through the Leroux Creek Draw

Eastern side of Cedar Drive, (spray will be 150 feet away from the following Cedar Drive westerly right of way/Bilchak property line: from Railroad tracks to 170 feet south of Shepherd’s Lane), then the ATV will continue to North of Shepherd’s Lane to Hotchkiss’ property.

In Paonia/North Midway:

Specific areas of Minnesota Creek drainage closer to the easterly edge of town of Paonia (W. Nile positive on RAMP), indicated by failure of larval, pupal, and barrier products to contain adult culex.

Roat Cap Creek area

Volunteer Park






BMW Rally in Paonia Park coming up this weekend! Campers will be setting up Wednesday night for a full slate of events in the Park.

Despite the great success of controlling mosquitoes in the Paonia park area over Cherry Days, NFMAD has continued to closely monitor the park area with extra traps in a perimeter, aggressive larval and pupal product applications, and searching the surrounding neighborhood and beyond for potential breeding sites.

NFMAD crew will be applying barrier spray to the entire park area either Monday or Tuesday nights, 7/22 or 7/23, depending on weather, after dark to avoid bees, or other flying mosquito predators, particularly to the camping areas and bandstand. This will be similar to the successful application of barrier spray before July 4th events.

The trap counts have been exceptionally low right up until two days ago…if you live in the vicinity, please call 527-6681 with any information where mosquitoes may be coming from, and check your own property. This is an enormous help to the crew in our “search and destroy” mission for breeding sites, as well as locating and treating adult hatches.

As always, consider wearing lightweight long sleeves and pants, with closed shoes if you are attending music events that take place at dusk…we are in the middle of mosquito high season and the biting buggers LOVE larger groups of people, with lights, food, and beer! Repellant application to your shoes, ankles, edges of shirt sleeves, ears, back of the neck, etc., is always a good idea if you are out at dusk in July and August.






Due to high trap counts and other threshold variables, weather permitting, there will be a targeted spraying of the following areas tonight, Thursday, July 18th, or tomorrow, Friday, July 19th in Hotchkiss:




Old Sewer Treatment

Delta County Fairgrounds

Riverside Road

Areas of Coal Rd., (not previously sprayed due to weather)

Hummingbird Ranch, through the Leroux Creek Draw

Eastern side of Cedar Drive, (spray will be 150 feet away from the following Cedar Drive westerly right of way/Bilchak property line: from Railroad tracks to 170 feet south of Shepherd’s Lane), then the ATV will continue to North of Shepherd’s Lane to Hotchkiss’ property.





Hello all,
Please email to ( with your organic agriculture information as there seems to be a fatal error in (!

We have laminated hot pink signs for posting your fence line or gate, etc. available at Tom Will’s Bookstore in Hotchkiss, or by calling 527-6681 to arrange for other pickup or mailing.

For Pesticide Sensitive Registry: we must have your registration paperwork on file to give you a hot pink Pesticide Sensitive sign to post. We need a map of your property with closest intersections to effectively post your property line.
Thank you!

Tomorrow night, 7/17 after 10pm, there will be targeted spraying of adulticide at Zack’s BBQ in Hotchkiss due to high trap numbers. Please clear the area by 10pm, thank you. If it rains, spraying will be delayed until 11pm, or until dawn on 7/18.

Notice: Either tonight or tomorrow, weather permitting, areas of Coal Rd. and Cedar Dr. will be target sprayed with adulticide. All appropriate notification has taken place as there are no residents within 200 feet of the proposed treatment zone.

The Bowie Mine area trap that tested positive on RAMP for WNV update:
In the last week, the area has been searched by the entire crew for breeding sites, treated with larval and pupal products in addition to an adulticide knockdown spray, and re-trapped. Unfortunately, the terrain in the area makes perimeter trapping almost impossible, however additional traps were set, and there is an ongoing expanded search for breeding sites. All trap pools for the entire Bowie area are now RAMP negative. NFMAD crew will continue to closely monitor the area.

The Lamborn Mesa Rd. area trap that tested positive on RAMP for WNV Update:
Chris and the entire crew combed an area up to 3/4 of a mile in every direction from the trap site starting at dawn yesterday. All neighbors within that zone were personally contacted, and their properties evaluated, physically mitigated when possible, and treated with larval products. Just after dawn, there was targeted adulticide, and a barrier spray applied in a circle around the property that hosted the trap, with the full participation of the owners and the immediate neighbors. A wider, multiple trap perimeter was set last night and all trap pools that have culex will be RAMP tested.
A huge thank you to Chris and the crew members for aggressive and diligent response! This process took many hours, and a lot of hiking and carrying of heavy bags of product. Many previously unknown sites were discovered, mapped, and treated, and will be added to the list of monitored breeding areas.



Red Alert! First two positive mosquito trap pools on RAMP testing for the North Fork District occurred today.

The positive pools were trapped in the east and south sides of the District. Confirmatory trapping is already taking place, and will be immediately RAMP tested. Chris Tschinkel and the crew are already in action, and all phases of treatment will continue including adulticide spraying where indicated.

More information will be posted as we have details.

Please, please, protect yourself and your family! We are now in mosquito high season. DO NOT go out at dawn and dusk without protective clothing and mosquito repellant as West Nile carriers are flying.

There is no mosquito product that will kill 100% of adult mosquitoes, so personal protection is essential.

As always, please police and check your own property, help your neighbors if they are unable to police their property, and continue to call in any possible breeding areas or sources you see to NFMAD at 527-6681

July 11, 2013

Update:  Due to rainy and windy weather, spraying will be delayed to tomorrow.

Notice: There will be adulticide targeted spraying at the Delta County Fairgrounds, the old Sewer treatment plant, Zack’s BBQ, lower Hansen Mesa Rd., and lower Cedar Dr., tonight after 9:00 pm, weather permitting. All appropriate notification has taken place for residents within 200 feet of the treated area.

July 10, 2013


Three mosquito trap pools in Delta District #1 have tested positive for West Nile virus on PCR testing:  the Oxbow area by the Gunnison river, the Hog farm area, and the G Rd. area.  Please take extra precautions if you live or work in these areas.  The positive trap pools were from the week of July 2nd.

The Delta County resident that contracted WNV in Mesa count 2 weeks ago, has recovered, thank God!

Notice:  in the North Fork District, targeted spraying with adulticide will occur tonight after 9pm weather permitting, in several locations, including a portion of Coburn Rd., Bell Creek Rd., Lund Rd., and Back River Rd.   All appropriate notification has taken place for residents within 200 feet of the treated area.


July 5, 2013

RED ALERT: First confirmed human West Nile Case at Delta Memorial Hospital:

The first person to have lab confirmation of W. Nile viral infection started having symptoms 11 days ago. We are waiting for the information on which part of the County is home for this resident. Depending on the form of WNV, flu-like or nervous system invasion, there could be anywhere from 10-30 residents of Delta County that are infected.


Despite all trap pools in NFMAD and June trap pools in Delta District #1 testing negative for WNV, there is a large portion of Delta Cty. that is NOT in either district, hence not being monitored by trapping. It is essential that every resident police their own property, and call for help if needed. Please, please wear repellant and avoid dawn and dusk outdoor activities whenever possible. If you or your family members must be outside, wear closed shoes and lightweight long sleeve clothing to reduce the amount of skin available to bite.  Avoid perfumes and scented products, such as laundry soap or sunscreen, as the scenting agents are mosquito attractants.

Update:  Ken Nordstrom, the director of Delta Cty. Public Health department has confirmed the first resident West Nile case in Delta County was probably bit by an infected mosquito while in Mesa County.  Mesa County has had 9 positive mosquito pools for W. Nile virus of 37 tested.


This is still a red alert for our District as Mesa County is quite a bit lower in elevation than the terrain in the North Fork District, and may be a sentinel zone.



July 3, 2013

Operations and General News

June 10  to June 29, 2013

Updates from the North Fork Mosquito Abatement District

The last two weeks have been quite busy in the District as mosquito season heated up, literally, with the increase in temperatures.  The crew has been working hard in the entire district, continuing both physical mitigation and treatment of sites with larval, pupal, and adulticide products when necessary.


West Nile Incidence

As of June 29, 2013 all trap pools with culex mosquitoes have been RAMP tested as negative for the presence of West Nile virus.  We are currently testing every trap, even with just one culex mosquito, to immediately catch the first W. Nile positive, if and when it occurs in the District.

Mesa County has had the first positive mosquito tested in the Western Slope area, while Boulder, Longmont, and other Front Range areas have had positive mosquito pools, but no human cases have been reported so far.

The CDC published a map, current as of June 25th, listing 6 human cases in the US, evenly split between the nervous system serious form of the viral infection, and the milder, flu-like version.  There has been one death in these six cases.  Of the 18 states reporting human, bird, and/or mosquito positive tests for West Nile, for the first time in over 10 years, Colorado is not on or at the top of the list.  Obviously, the positive tests from Mesa, Boulder, and Longmont occurred after 6/25.

At this time in 2012, there were already over two thousand W. Nile viral cases in 13 states, and Colorado was fourth on the list for incidence, with Delta County at the top of the list for our state. In the North Fork District last year, positive mosquito pools on PCR testing were already widespread, with many human cases occurring.  We have been blessed with cooler nighttime temperatures far into June this year, resulting in a slower development and appearance of adult mosquitoes.


Event and Recreational Areas and Parks

With the arrival of summer weather and outdoor recreational activities and community events, NFMAD has significantly expanded the surveillance and monitoring program for the 2013 season for all parks and outdoor venues.  We are working closely with Public Works, the towns of Paonia and Hotchkiss, the County Fair board, and various other groups, to provide as safe and comfortable an environment for our residents as possible.

NFMAD has been trapping all sentinel sites since late-May, with the addition of up to 20 sites, to aid the search for breeding areas or other sources of adult mosquitoes.  Despite very low numbers of adult mosquitoes caught, we continued to set traps throughout the District, with extra traps set in perimeters around historical hotspots that had high numbers of adults in previous years.  These hotspots included the County Fairgrounds, Paonia Park, Volunteer Park, and Zack’s BBQ.  The District board added Willow Hts. Park, the Old Sewer treatment plant, the Rodeo grounds, and various school locations.

As a result of this type of trapping, the crew was able to immediately respond to the first large hatch of adult mosquitoes in the Old Sewer plant and Fairgrounds areas of Hotchkiss with aggressive larval and pupal treatments, and then targeted adulticide spraying when indicated.

At the old sewer plant, trap numbers jumped to 530 the week of June 10th, then dropped to 324 after backpack spraying, then down to 11 after ATV targeted spraying.  Thank you to Zach Hotchkiss again, for very late evening ATV applications of adulticide!  There have been several instances where the adults did not come out in force until after 11pm, and Zach has been willing to get the job done despite the late hours.


Additional traps continued to be set in a perimeter to aid in the search for breeding areas, and to monitor treatment response.  There have been a number of breeding sites identified that were not previously recorded on operations maps, and the crew continues to aggressively treat the entire area.

The County Fairgrounds have also been adulticide sprayed due to trap evidence, and unacceptably small drops in adult mosquito presence after aggressive larval, pupal, and barrier treatments had been applied.  The areas under the bleachers, etc., have also been barrier sprayed.  There is a marshy area that despite heavy treatment, has required adulticide spray to keep the trap counts lower than threshold levels.

Willow Heights Park had very low trap counts, yet numerous complaints of adult mosquitoes in the area were coming in, so Chris Tschinkel and the crew surveyed the area in widening circles until the source of mosquitoes was identified.  A tight perimeter of traps was also widened to aid the direction of the search.  Again, aggressive larval and pupal products were applied, monitored, and then targeted adulticide was applied to knock down the adults when insufficient response occurred to the other products.

As the July 4th holidays and events approach, adult mosquitoes seem to be under control in the parks and recreational areas of Hotchkiss.

Paonia Park has had exceptionally low trap counts as a result of early physical mitigation, and barrier treatment of culverts.  A perimeter was set for two weeks, and counts came in from 0-2 adults/trap, with zero presence of culex adult mosquitoes.  Weekly trapping has continued, without as tight of a perimeter.  The area is in great shape coming up to Cherry Days, and will continue to be closely monitored as the BMW rally approaches later in July.

Volunteer Park in Paonia has been extensively trapped in a widening perimeter, treated with larval and pupal products as well as barrier spray, and also targeted with adulticide spray, particularly the baseball fields.  In early June, many complaints were registered about the ball fields having numerous biting adult mosquitoes, however now that the entire area has been treated, calls have dropped to zero.  The Kropp organic orchards on the eastern border of the park have been treated with aggressive larvicides, and no adulticide or barrier spray or drift has come within 200 feet of the boundary line of the orchard.

The Rodeo grounds, across the river from Delicious Orchards, have been extensively treated with a full complement of products including barrier spray, coming up to the July 4th events.



General District News

–Physical mitigation efforts that began in March have made a major impact in low trap counts all over the district, even in historical hotspot areas.  The concentrated residential areas of both Hotchkiss and Paonia have had very, very low trap counts throughout June, and minor upticks directed increased search for breeding areas.

A lot of physical mitigation was accomplished in the Midway area between the towns, but much more remains to be done in the future as money is available, with the possibility of grants for serious shifting of the river corridor.

There are many places along the irrigation canals and ditches throughout the District that required shovel and backhoe work to open the drainage.  With the growth of underbrush advancing rapidly, some of the work has to be postponed until next year in late winter, early spring.

–Mapping of organic farms, vineyards, orchards, dairies, and other cottage industries, as well as bee hive locations, continues in the District. This has been an essential process for the North Fork District to fully communicate the level of economic hardship to local, state, and federal government authorities on what would happen if aerial fogging occurred in the District.

Delta County Map department made amazing, large maps of both towns and the area between with clear details.  These have been very helpful in identifying possible areas of breeding and siting traps as well, and also for creating a comprehensive listing of areas that must not be adulticide sprayed in the event that truck fogging becomes necessary.


–The Delta County Public Health department director, Ken Nordstrom, has made a public statement of support for NFMAD’s operations plan, and confirmed the North Fork valley will not be aerial fogged unless there is a   serious widespread epidemic of W. Nile illness, and all other attempts to manage and mitigate have totally failed.

It is sobering to understand how important it is to manage adult mosquito populations in the District, staying well below mandated thresholds of the CDC and CO. Public Health Departments, in order to avoid treatment choice being taken away from the District board and residents.  Due to widespread West Nile illness in the District last season, and many positive mosquito trap pools on PCR testing, it is imperative that a full phased program be utilized whenever and wherever necessary to control the adult populations of mosquitoes.   This is the only path to maintaining control over mosquito abatement in the District.

Ken Nordstrom confirmed that aerial fogging will not take place without the full knowledge and support of the NFMAD board of directors, and a clear and present danger of epidemic illness, with utter failure of all control measures.   Delta District #1 is considering aerial fogging along the Gunnison River corridor due to access issues along an Oxbow property with a lot of winter tree damage, and possibly a fogging of a large area from Orchard City to Olathe, including the town of Delta.  Other counties, including Gunnison County, have publicly stated that aerial fogging programs are being abandoned, for various reasons including economics, lack of effective adult control and kill rate, environmental impact and compliance with NPDES (National Pesticide Discharge Management Plan that became law on 6/1/13), and public relations issues with residents.


–Thank you to all residents for eliminating breeding sites on your property!  This is an enormous help to the crew in managing adult hatches of mosquitoes.  In the last two weeks there are many examples of private property hosting breeding sites in old flower vase water, pool covers, garden ornaments, old tires in the shade, annual pot bottoms, birdbaths, and other inadvertent hatching stations. One property had a decorative causeway installed by previous owners that created an actual non-draining swamp out of a backyard!  With 50 square miles in the North Fork District, it is so incredibly helpful when residents evaluate their own property.  Thank you again, so much!

–Financially, Operations are within the limited District budget as the assumed “midpoint” of mosquito season approaches.  This could change overnight with an outbreak of mosquito-borne illness or the loss of a major piece of equipment, but for this moment we are well within projected budget levels for payroll, product, and other operating expenses.  Fundraising efforts have supported the purchase of the RAMP reader, the first 100 tests, and some of the costs of the new equipment purchased. Thank you to all of our donors for your support.

–The District is in desperate need of an ATV to use in the Paonia area…please let us know if you have a donation, a loaner, a trade-in, or any information that could help us track down an affordable option.  Zach Hotchkiss has graciously allowed NFMAD to mount the ATV sprayer on his personal equipment, so again, thank you to Zach!




Future planning:

–Mapping is underway in Hotchkiss and Paonia of the Union Pacific Railroad tracks, with detailed notes on mosquito habitat issues along the railway.  Several individuals have offered support with communicating with the Railroad Company, which is greatly appreciated.  The District is working on the survey so a meaningful meeting can be planned.

–A list of possible places that can be burned as physical mitigation late winter, early spring is being compiled for the entire district, along with a backhoe and crew of shovels list.  Many areas that require equipment to fully shift breeding habitat and drainage issues will need financial assistance and application to various governmental agencies to coordinate.  This is an ongoing area of strategic planning for the winter of 2014, and future years.

–Tom Wills has been working with the county and both towns’ planning/zoning departments so that NFMAD will be informed of construction and any drainage issues that could be either remedied or created by proposed plans.  Thank you, Tom!

-As a result of meetings Rain had in late June with the Planet Heritage Foundation, NFMAD will be preparing a grant request for the N. Fork of the Gunnison river corridor for 2014.  A comprehensive list detailing irrigation and canals, waste water, storm drainage and public works, as well as the considerations of returning quality water to increase stream flow and health of the river is needed as the basis of a grant request.  Obviously, this will require a lot of time and effort to coordinate this level of surveying, and will also require volunteers with different skill sets.  There are many groups involved including the Nature Conservancy, Trout Unlimited, NRCS Natural Resource Conservation Services, and the local conservation groups, in the effort to create a comprehensive plan for the health of the rivers that feed the Colorado.

For NFMAD, the particular focus of the grant request will center on the North Fork of the Gunnison river corridor, the 100 and 500 year flood plains, irrigation tail waters and returning water to the river, and of course, drainage issues through lower Hotchkiss, Midway, and along particular areas of Paonia.


(Respectfully submitted, 7/2/13 REK)


July 2, 2013

NOTICE: due to high numbers of trapped adult mosquitoes and other threshold factors, the Lund Rd and Rodeo grounds area will be sprayed with adulticide tonight or tomorrow night depending on weather conditions. The rodeo grounds will also be barrier sprayed. Required notification has been given to all affected residents of the area. We ask that the area be clear as of 8:30 p.m., thank you.

June 19, 2013

Notice: Willow Heights Park Update: Through extensive trapping and searching, the breeding sites that are feeding adult mosquitoes into the park have been located and treated. Tonight between the hours of 9 and 11pm, there will be a targeted spray in the area to knockdown the adult population. We need the park area clear and unoccupied prior to spraying. Thank you.

Notice: Volunteer Park in Paonia will be target-sprayed tonight, June 19th, sometime between 9 and 11pm. We need the park clear and unoccupied prior to spraying. Thank you.



June 14, 2013

Have you been registered as pesticide-sensitive in the state of Colorado in the past?

As of June 1, 2013, the Department of Agriculture and the Colorado Pesticide Registry no longer keep information on file past the end of the previous year.


This means NFMAD does not have a comprehensive list for 2013, and cannot access this information through the Denver offices.  We need your help!  Even if  you were registered previously, the pesticide sensitivity must be renewed for the 2013 season.


Please renew as soon as possible and then either call NFMAD at 527-6681 with your registry information or email to ( We are printing and laminating consistent signs for residents that are registered with the CO. Pesticide Registry to post on your fence or gate, etc.

If you have been diagnosed with asthma or other respiratory condition, please consider registering as pesticide sensitive with the state.  NFMAD must comply with federal and state laws and cannot directly register residents, this must be done through the state offices.
Do You have an organic/biodynamic farm or bee hives? 


NFMAD is creating a comprehensive mapping of organic/biodynamic agriculture, as well as the location of bee hives.  Please call 527-6681 or email (  at your earliest convenience with the following information:


Your name, address, telephone number, email, and the closest intersection of roads.
If you are renting your home or farm, please include the name of the owners if known.  This will help us locate the parcel on the county maps.


This is NOT a listing of Pesticide Sensitive residents, please see the information above if you are registered.
Due to West Nile viral infection attaining epidemic classification by the Center for Disease Control (CDC) as of December 11, 2012 the rules and regulations for mosquito abatement have changed drastically.  We have just received news that several surrounding mosquito districts are pooling resources to mount an aerial spray of adulticide in the Delta, Orchard City, and Olathe areas.

We absolutely do not want aerial spraying to occur within the District boundaries! 

Comprehensive mapping of the North Fork District’s organic farms, vineyards, orchards, and bee hives will support NFMAD’s case against aerial spraying of any kind with the county and state governments, as well as avoiding the deleterious effects on our environment and economy.
Controlled, targeted, spraying of adulticide using backpack, ATV, and/or Ultra Low Volume truck mounted spray units, is occurring in the District  according to strict trapping and RAMP testing results while NFMAD crew members are destroying breeding habitat, applying larval and pupal products, and spraying barrier oils to kill the mosquito eggs, larvae, and pupae, before becoming flying adults.  However, if the adult mosquito populations rise past federal threshold levels, due to the epidemic status of W. Nile viral illness, the District could be aerial sprayed regardless of our operations plan and local thresholds, and despite all protests.

When trap numbers hit thresholds,  spraying of adulticide will occur if appropriate,  and spraying of adulticide is controlled, including wind drift, in accordance with the law and common sense.  The  ground search for the breeding sites widens in quarter mile increments, and the larval and pupal products are stepped up in concentration and frequency.

We are committed to protecting our organic agriculture and economy while also eradicating mosquito-borne illness.   Please call or email with the information listed above for your organic agriculture.


Consider booking an appointment for a site evaluation for your property to hopefully eliminate any mosquito breeding issues well before the flying adult phase, so that larval products can be applied safely, even on organic farms.

We are in the process of mapping all the organic farms, orchards, vineyards, and personal gardens in the North fork mosquito district. There is not a comprehensive map in Delta Cty. of bee hives, organic/biodynamic registrations, IPM areas of agriculture, etc., and the current board is committed to identifying all areas of the district that should not be sprayed with adulticides, regardless of “environmentally friendly” labeling.
We need your help!
We are all very over-worked volunteers attempting to comply with federal and state mandates and laws while also protecting our valley and the wealth of organic agriculture here, and any help would be greatly appreciated.


Please call 527-6681, fax to 527-8259, or email (, with the following information:

1. Your name, address/location, telephone number, email/website, the type of agriculture on your land, presence of bee hives, etc.

2. The closest intersection of roads to your land

3. The names of your neighbors, if you know.

With this information, we can locate your parcel on the huge map of the District at the Harvester Building District office.


We are in the process of having “No Spray” signs printed at High Country printers that will be available. Ideally, if VOGA members and other organic concerns would be willing to post fence lines, gates, or other visible areas with a consistent sign the crew can immediately recognize, we believe the district can be successful in protecting agriculture and organic lifestyle while also breaking a West Nile viral epidemic.


If you or a loved one are pesticide-sensitive, please go to the links page for information on the Colorado Pesticide-Sensitive registry.  If you are on the Colorado Pesticide Registry, we need this information as soon as possible. We are also producing a sign that lists “Pesticide Sensitivity”.

Please feel free to call or email with questions or comments. Thank you!





May June Operations Report
For the Towns of Hotchkiss, Paonia and Delta County

June 8, 2013

All trap pools from the week of June 3rd have tested negative for the presence of West Nile virus, by the RAMP reader.


We are so grateful for the financial support of the towns of Hotchkiss and Paonia, the grant from the Planet Heritage Foundation, and the many private contributions that have been received to defray the costs of purchasing the equipment and necessary lab accessories.  Thank you!
June 7, 2013
Mosquito season started late in the North Fork (thank goodness) compared to last year, with the first culex (possible West Nile carrier) larvae noted in early June. Total numbers are still low, particularly in Paonia, as a result of cooler nighttime temperatures in the eastern portion of the district. The massive efforts towards physical mitigation using shovels and backhoe/trackhoe equipment has paid off around the Hotchkiss area with resulting low trap counts and the absence of signs of breeding in historical hotspots.
Trapping commmenced in sentinel areas at the end of April, with zero mosquitoes caught until the 3rd week of May. The counts at the end of May were below 5 per trap. Trapping the week of June 3 in the Hotchkiss area showed an uptick around the Fairgrounds and the old waste-water treatment plant.
In Paonia, trap counts remained at zero. In the Midway area between the towns, an uptick in counts occurred in the Burgess Lane area, as well as Skyhill Rd. However, the efforts to physically drain low areas in Pumpkin Hollow, along the Carsten property, and the Campbell’s, has resulted in flat trap counts. Yes! The Bowie area has not had any mosquito activity thus far this year. Trap numbers otherwise have remained amazingly low, again, in the areas that have been major problems in previous years. After a few initial, technical, equipment-related problems the staff has now hit their stride in conducting the trapping to determine where the problem areas are.
Chris Tschinkel, the field manager, and the crew have been working hard monitoring, dipping, and treating sites with larval and pupal products all around Hotchkiss, in both historical problem sites and newly discovered areas. Many areas received special attention with barrier sprays and larvacidal oil, particularly on the upper-side of the railroad tracks, Lorah Lane by the K-8 School, the trailer park North of City Market, the lower portion of the Fairgrounds, and others. Short Draw swamps still weren’t breeding culex in early June due to the coolness of the water but we continue to monitor.
In the Paonia area, the German creek/Skyhill Rd. site is being closely monitored and treated. Treatment has occurred on Stahl Rd, the Redwood Arms motel, and the corridor along the river to the back of Delicious Orchards, as these are the first sites where breeding activity has been observed.
Board member, Zach Hotchkiss, has been working with a backhoe for the last 2 months, physically mitigating areas that have been breeding problems in the past on his property. The NFMAD crew has contributed shovel power to the efforts on several occasions and recently treated the ranch with long-acting product. NFMAD has also provided Zach with larvacide for the irrigated fields so that he can treat immediately upon seeing any activity as the water dries down. The district purchased an ATV spray unit, currently mounted onto Zach’s John Deere side by side ATV, to treat his own property as well as the Hotchkiss area. The district is looking for an ATV in the Paonia area for a similar arrangement. Zach Hotchkiss is donating his time and equipment to support the efforts of NFMAD, which should make a huge difference in the neighboring parts of town plus make our limited staff hours stretch further. Go, Zach! Thank you!




We have deep gratitude to the Public Works departments of both towns and the county for all the efforts supporting physical mitigation of breeding habitat in the District. Thank you!
Other residents in the district have also been working hard on mitigating possible breeding sites on their property, including Mindy Bell, Bill Carsten, Eddie Clement, DeeDee Durrance, Glenn Austin, Jeff Schwartz, Addie Cranston, Mary DiFranco and Bobby Orlando, among many others. Thank you so much for the coordinated efforts! Please keep in mind that NFMAD welcomes all reports, observations, tips and tricks, and any other help to find and destroy mosquitoes. We offer free site evaluation and possible treatment plans, just call for an appointment.
In addition to a new array of long-acting aggressive larvacides, the District has purchased products that specifically treat culverts, storm drainage, livestock tanks, and irrigated fields that may dry between watering cycles. Altosid briquets can dry down up to 10 times and still exert mosquito control. The district has also received delivery on a variety of new treatment products such as BT treated sandgrains designed to penetrate into swamps where treated corncob BT would just get hung up on vegetation.
NFMAD has also purchased 2 new adulticide products effective in lower volume, for use in the new backpack spray units, which can be specifically calibrated to reduce environmental impact, particularly on non-target species. Targeted, focal spraying will be utilized in areas where thresholds are reached, as well as by monitoring trap numbers or when RAMP testing indicates the presence of WNV. A new adulticide is coming on the market in late-June that is rated for safe use even on agricultural crops that are certified organic, which will be very useful for the North Fork valley.




The entire crew attended a class taught by Gale Jirik in Grand Junction on May 31st, receiving training on the new array of products in NFMAD’s arsenal.
Future planning for Hotchkiss area:
NFMAD would like to work with the Town of Hotchkiss, as well as the Board of County Commissioners, to develop a relationship with the Union Pacific Railroad. NFMAD has confirmed that the water trapped on the upper side of the railroad grade all though the town and related culverts etc. is a major portion of the breeding issues in town. Unfortunately, West
Nile virus carrier species, such as Culex tarsalis, prefer this type of standing water habitat as prime breeding territory, and can literally go from egg to flying adult in 3 days in high temperature, shallow waters.
Ideally a long term plan would include the railroad doing grading and or piping to eliminate the stagnant water pools and keep everything draining and flowing. Most of the water is coming from groundwater seeps so the water itself can’t be eliminated, since it is not simply irrigation tailwater as previously assumed.
This entire railroad corridor is growing massive numbers of mosquitoes in a highly populated area, that also has schools and recreational facilities. Given that there is not one single mosquito control product that has a 100% kill rate, this is the primary, long-term issue for eradicating mosquito-borne illness and issues for the town of Hotchkiss.





Future Planning for Midway:
NFMAD has been in consultation with Delta County mapping, engineers, and the public works department about the river corridor in Midway. The 100 and 500 year flood planes are actually over 50 feet from the bank of the river in some areas due to the land in Pumpkin Hollow being so low. This will require the participation of the Army Corp of Engineers, as well as state and local entities to correct, and will take a substantial financial grant to accomplish the work. This will not be possible for the mosquito district to fully mitigate under these circumstances, hence in the 2013 season, the area will be managed using product (pesticides).
Property owners in the Pumpkin Hollow area need financial and public works support to improve drainage and flow of water. NFMAD is coordinating any possible work that can be accomplished this season, while drafting a plan for the winter and spring of 2014.
Future Planning for Paonia:
The railroad is also an issue in some parts of the Paonia area, however, the river corridor represents a much larger Paonia issue for future financial needs of the District. The Matthews Lane, Stewart Mesa Rd. area has massive drainage issues that are beyond the scope of the individual property owners or the District, and will require financial assistance by the state and/or federal governments.
Public Works for All Areas
And of course we very much appreciate such things as weed control (weeds harbor adult mosquitoes during the day), and particularly encourage controlled burns for high vegetation areas by the Fire Departments. As always, removal or coverage of things such as open containers, junk and barrels. Just one small container can breed hundreds, if not thousands, of adult mosquitoes of various species that ALL carry some form of illness, from West Nile virus to Dengue fever, and heartworm in pets.
