General information on Pesticides MMCD uses for larval control
Bti – larval black flies and mosquitoes
Bacillus thuringiensis var. israelensis (Bti) is a natural soil bacteria that disrupts mosquito digestion. This product is dispensed by hand in small sites and by helicopter in larger sites.
Bacillus sphaericus – larval mosquitoes
Bacillus Sphaericus is a naturally occurring bacterium that is found in the United States and throughout the world. Its active ingredient kills mosquito larvae when the larvae ingest the bacterial spores in moist or wet areas such as lakes, coasts, streams, swamps, and drainage ditches.
Methoprene – larval mosquitoes
Methoprene is an insect growth regulator which specifically mimics the mosquitoes’ juvenile growth hormone, preventing the mosquito from emerging from the pupal stage. This is a time released product dispensed in briquet or pellet form.
Spinosad – larval mosquitoes
Spinosad is a natural substance made by a soil bacterium that can be toxic to insects. It is a mixture of two chemicals called spinosyn A and spinosyn D. It is used to control a wide variety of pests, including mosquitoes.
Pesticides used for adult control
Pyrethroids – i.e., Permethrin, Sumithrin, Etofenprox
Pyrethroid products such as Permethrin, Sumithrin and Etofenprox are similar to a natural botanical insecticide derived from chrysanthemums, and kill mosquitoes on contact. Specificity is determined by method of application. MMCD controls adult mosquitoes in response to complaints about excessive annoyance, and in response to mosquito-borne disease risk.
MMCD Hotline and pesticide impact studies
Adulticide Hotline is on line from Memorial Day to Labor Day. The hotline is updated around 4 p.m. each day during the summer to let people know where and when adult mosquito control treatments are scheduled. Phone: 651-643-8383
