WALTHAM, MA — The East Middlesex Mosquito Control Project will be controlling mosquitoes using an Ultra Low Volume truck mounted aerosol sprayer in neighborhoods of Waltham on Monday from dusk until 11:30 p.m. city officials announced.

The folks who will be affected are those who live in the neighborhood east of Porter Road and Arcadia Avenue to the Waltham border. Shirley Road, Warwick Avenue, Doty Street, Ledge Road, Harrington Road, Lakeview Terrace, Amherst Avenue. and Sachem Street will all also be targeted by the truck. Officials are asking folks to go inside if you see the truck spraying.

The Project sprays for mosquitoes using the pesticide, sumithrin, in a product called Anvil. Sumithrin 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. But with any pesticide, people should minimize exposure, experts say If residents see a spray truck approaching, officials ask you to go indoors, and keep the window closed for a few minutes while the spray dissipates.

Officials say if you keep bees, you do not need to take any special precautions since spraying begins after dusk. If you have any questions about the spraying schedule on mosquitoes, contact the East Middlesex Mosquito Control Project at 781-899-5730.
