Sudbury Mosquito Spraying Underway

SUDBURY, 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 Sudbury. The application was originally set for April 22 – 26 but rain delayed the process. Application is now being conducted from April 29 – May 3.

Wetlands currently being evaluated for this application are located near Crescent La., Hayden Cir., Hudson Rd. opposite Craven La., Maynard Rd., Meadowbrook Circle, Old Garrison Rd., Pantry Brook, Powers Rd., Virginia Ridge, Wake Robin Rd., and Willis Pond. The Bti will be applied in a granular formulation by a helicopter flying low directly over the wetlands. Residents do not need to take any special precautions for this application.

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
