THE BRONX - The city's Health Department is taking action to lower the threat of mosquitoes and the West Nile virus in the borough.
Helicopters will be spraying bug-prone areas with larvicide, a pesticide that is not toxic to humans, through Friday.
Marshy land in and around Pelham Bay Park is being targeted, along with parts of Queens and Staten Island.
