The East Middlesex Mosquito Control Project is planning to use a truck mounted aerosol sprayer to control mosquitoes in Sudbury. Spraying will be done between sunset and 11:30 PM.

On Tuesday, August 18, 2020, spraying will be done in areas of Sudbury that are located in the vicinity of Powder Mill Rd., Powers Rd., Dakin Rd., North Rd., Ford Rd., Mossman Rd., Haynes Rd., Pantry Rd., Morse Rd. and Thompson Dr.

If postponed, spraying will be rescheduled for the week beginning August 24, 2020.

The Project uses a spray formulation that contains the pesticide product, Anvil, to control mosquitoes. Anvil contains the pesticide, sumithrin, which is a pyrethroid that is classified as slightly toxic by the EPA. Mosquito control applications of sumithrin do not pose a significant risk to people or their pets due to the low toxicity of sumithrin and the small amount used to control mosquitoes. As with any pesticide, people should minimize their exposure. If residents see a spray truck approaching, they are advised to go indoors for a few minutes while the spray dissipates. Residents are also advised to close windows. Beekeepers do not need to take any special precautions since spraying begins after sunset.
