Mosquito Spray Notice for Portions of Reading

Spraying planned for July 23, 2020

The East Middlesex Mosquito Control Project is planning to use a truck mounted aerosol sprayer to apply Sumithrin in Reading on Thursday, July 23, 2020.  All spraying is done between sunset and 11:30 PM.

Spraying will be done in areas of Reading that are located in the vicinity of Spruce Rd., Margaret Rd., Prospect St., Randall Rd., Oak St. and Sherwood Rd.

If postponed, spraying will be rescheduled for the week beginning July 27, 2020.

East Middlesex uses a product called 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 exposure.  If residents see a spray truck approaching, they are advised to go indoors for a couple of 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.

If residents have any questions related to mosquitoes or mosquito control, contact the East Middlesex Mosquito Control Project at 781-899-5730. The spray schedule can be found at the Project website at
