Westerly residents may be awakened to the sounds of helicopters overhead Thursday morning. Continuing a practice begun in 1997, the town of Westerly is conducting aerial spraying against mosquitos.
The targeted areas are portions of Chapman Swamp and the swamp area adjacent to Hespar Drive.
The town uses Bti, a naturally occurring bacterium which prevents larval mosquitoes from developing into adults. The state Department of Environmental Management says it safe to humans and the environment.
Spraying begins Thursday at 7:00am and continues through 2:00pm.
