In accordance with state law, an aerial application is targeting mosquito larvae over certain areas of the Norfolk County Mosquito Control District.

In addition to Milton, the district will be conducting helicopter applications of the biorational larvicide Bti (Bacillus thuringiensis israelensis) over specific large wetlands in the towns of Avon, Bellingham, Braintree, Canton, Dedham, Dover, Foxboro, Franklin, Holbrook, Medfield, Medway, Millis, Needham, Norfolk, Norwood, Plainville, Quincy, Randolph, Sharon, Stoughton, Walpole, Westwood, Weymouth, and Wrentham.

These applications will be conducted for two to four days at any time between April 16 and April 26. As always, the weather in the spring is unpredictable, so for this reason, the district cannot pin down actual application dates with more accuracy.

The trade name of the granular formulations of Bti to be used is VectoBac GR (EPA Reg. #73049-486).
