Suffolk County Vector Control is scheduled to start spraying salt marshes Tuesday to control mosquito larvae -- the first aerial treatment of the season, officials said.
Low-altitude, helicopter droplet pesticides will be sprayed throughout coastal communities. Spraying could be rescheduled due to rainy conditions.
County officials said residents don't need to take any precautions and any human exposure is unlikely. Helicopters are flying at low levels and pesticides are nontoxic to humans, officials said.
The first phase of spraying is scheduled Tuesday from 5 a.m. to 8 p.m. in Babylon: Gilgo, West Gilgo, Cedar Beach and Oak Island.
In Islip: Gardiner County Park, Heckscher State Park and Seatuck National Wildlife Reserve, pending Fish and Wildlife approval.
In Southampton: Stokes Poges, West Hampton Dunes, Meadow Lane, Iron Point, North Sea and Accabonac Harbor in East Hampton.
In Riverhead: Indian Island, Aquebogue Farm and Overlook, Crescent Duck Farm, Millar Farm, Beaverdam Creek and Pier Avenue.
In Southold: New Suffolk, Kerwin Boulevard, Pipes Neck Creek and Pipes Cove.
