Heads up - The East Middlesex Mosquito Control Project will be controlling mosquitoes using ULV (Ultra Low Volume) truck mounted aerosol sprayers in neighborhoods of Waltham TONIGHT, June 12th starting after dusk and ending by 11:30pm. 

Areas to be sprayed are located near Bacon St. between Plympton St. and Curve St. Spraying will also be done in areas near Kingston Rd., Sheffield Rd., Hardy Pond Rd., Graymore Rd. and Hibiscus Ave. If spraying is postponed due to weather, it will be rescheduled for Thursday, June 14th.

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. As with any pesticide, people should minimize 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 dusk.

Information on the spray schedule is available via a recorded message at 781-893-5759 and at the Project’s website at https://sudbury.ma.us/emmcp/ . If residents have any questions related to spraying or any questions on mosquitoes, contact the East Middlesex Mosquito Control Project at 781-899-5730.
