Suffolk County is planning to spray for adult mosquitoes Tuesday and Wednesday, weather permitting, with spraying for larvae on Tuesday in parts of area salt marshes, health officials said.
Ground spraying of streets in the villages of Davis Park and Point O'Woods on Fire Island is to be conducted Tuesday from 6 p.m. to 10 p.m. with the pesticide Anvil, officials said.
Also on Tuesday, from 5 a.m. to 8 p.m., areas of salt marshes in the towns of Babylon, Islip, Brookhaven, Southampton, East Hampton, Riverhead and Southold are scheduled to be treated aerially with an eye toward controlling mosquito larvae, the county health department said.
Precautions are not necessary, health officials said, as "the helicopter will be flying at a very low level over marsh areas and taking other precautions to control airborne drift into inhabited areas."
Pesticides being used -- in this case, Vectobac 12AS and Altosid liquid -- "have no significant human toxicity," officials said.
On Wednesday from 6 p.m. to 10 p.m., ground spraying with Anvil is scheduled for all streets in the Fire Island villages of Ocean Bay Park, Seaview and Ocean Beach. And from 7:30 p.m. to 11:30 p.m. Wednesday, aerial spraying with Anvil is planned for adult mosquitoes in Amityville, Copiague, Lindenhurst, North Amityville and North Lindenhurst.
Besides being annoying, some mosquitoes' bites can transmit West Nile virus to people.
The chances of experiencing health effects from the spraying for adult mosquitoes are "quite low," the health department said, but children and pregnant women should avoid exposure if possible by staying clear of the area during spraying and at least 30 minutes after.
Among the "common-sense steps" the department suggests are closing doors, windows and air-conditioning vents during spraying and 30 minutes after.
