Suffolk County is planning ground spraying Tuesday, weather permitting, for adult mosquitoes on Fire Island, health officials said.
Streets in the villages of Davis Park and Point O'Woods are to be sprayed from 6 to 10 p.m. with the pesticide Anvil, officials said.
Besides being annoying, some mosquitoes' bites can transmit West Nile virus to people.
The chances of experiencing health effects from the ground spraying are "quite low," the county 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.
