NFMAD uses a variety of larvicides and pupacides that are target-specific, killing the juvenile mosquito before it emerges as a flying and biting adult. The District uses larval and pupal products that increase in aggressiveness if trap counts do not drop. If thresholds are reached, or there is a W. Nile positive in the trap pool, adulticides will be used in a targeted, focused manner.
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.
The order of preference for treatment is as follows:
1. Larvicides: Bti products:
Aquabac comes in several forms, including: shredded corn cobs, sand granules, briquets, and liquid. Each form has a specific terrain it is appropriate to treat.
Larvicides: Bs products
Or a product that is a combination of both Bti and Bs, soil bacteria on sand granules:
FourStar Sand Granules
2. Altosid: Methoprene
Altosid comes in many forms, and the primary ones NFMAD employs are the briquets and the sand granules. It also comes in a liquid.
Altosid has methoprene as the active ingredient, a growth hormone that holds the juvenile mosquito in the metamorphoses state wherein they cannot feed and starve, hence die.
3. BVA larvicide oil
BVA is a blend of food-grade mineral oils that inhibits surface tension, which juvenile mosquitoes rely on to rest. No rest means death. BVA is also used as a barrier spray, although it will “burn” foliage on contact…excellent for choking weeds that block drainage, not good for hay or other field crops.
4. Adulticide Products:
