Suffolk County Tuesday plans to spray pesticides in two Fire Island neighborhoods to reduce adult and larval mosquito populations, and will use helicopters to spray numerous marshes in Southold, Riverhead, Islip, Southampton, East Hampton, Brookhaven and Babylon.
The county will carry out low-altitude spraying of large-droplet methoprene from 5 to 8 p.m. to control mosquito larva.
"No precautions are recommended to prepare for this spraying," the department said, because the helicopter will "fly at a very low level over marsh areas." Other precautions will be taken to control drift, the county said in a statement. "Human exposure from this operation is unlikely and the products involved have no significant human toxicity."
Helicopters will spray methoprene in the following communities:
Babylon Town, in Sore Thumb, Oak Beach, Gilgo, West Gilgo, Cedar Beach, and Oak Island.
Southampton Town, in North Sea and Meadow Lane.
Riverhead Town, in Indian Island, Crescent Duck Farm, Aquebogue Farm and Millar Farm.
Southold Town, in New Suffolk, Great Hog Neck, Kerwin Boulevard, Pipes Neck Creek and Pipes Cove.
