Mosquito Spraying Underway In Wayland

WAYLAND, MA — The East Middlesex Mosquito Control Project will conduct aerial spraying of the biological larvicide Bti to control mosquito larvae over large wetland areas in Wayland. Application started by helicopter on April 22 and will continue on Friday the 26.

The spots affected include Pod Meadow and wetlands near Claypit Hill Road, Deer Run, Forty Acre Drive, and Plain Road. If you see helicopters over head, don't panic, residents don't have to take any special precautions.

Bti is a natural bacterium found in soil, according to the East Middlesex Mosquito Control Project. The EPA classifies it as a relatively non-toxic pesticide, and it solely affects mosquito larvae and a few related aquatic insects in the fly family.

Once applied, Bti stays suspended in the water for 1-2 days and biodegrades as it settles to the bottom. For further information, contact the East Middlesex Mosquito Control Project at 781-899-5730.
