Where are larvicides used to kill mosquitoes?
The New York City Department of Health and Mental Hygiene applies larvicides to standing water where mosquitoes can breed. DOHMH generally uses the briquet and granule forms of larvicides in catch basins (storm drains). The products will be placed into the storm drains by hand. For other types of standing water, granules or liquid products may be applied by hand, or sprayed from backpacks or trucks. For wetlands, swamps and marshes, where access may be difficult, larvicide may be applied from a helicopter.
