What larvicides will be used to control the larval mosquito population?
DOHMH will use Bacillus sphaericus (Vectolex), and Bacillus thuringiensis israelensis (Aquabac, Mosquito Dunks, Bti Dunks or Vectobac) and/or Methoprene (Altosid). These products have been approved for mosquito control by the U. S. Environmental Protection Agency and the New York State Department of Environmental Conservation (NYSDEC). Altosid mimics an insect growth hormone and prevents the development of adult mosquitoes from pupae. Vectolex, Aquabac, Mosquito Dunks, Bti Dunks are Vectobac are bacterial pesticides that can damage the gut of the mosquito larvae that feed on them, causing the larvae to starve to death. All three have been found to be highly effective in larval mosquito control.
