Ground spraying to control adult mosquito populations in parts of Fire Island is scheduled for Tuesday from 6 to 10 p.m., Suffolk County health officials said.
Spraying will cover all streets in the villages of Davis Park and Point O'Woods, weather permitting, officials said.
The pesticide application is designed to limit the development of mosquitoes, which through bites can spread West Nile virus.
Chances of experiencing medical problems from the applications are low, health officials said, but residents may want to avoid exposure, with children and pregnant women especially advised to stay indoors during the treatment and for 30 minutes after.
