Mosquito Spraying Planned for Tuesday evening, July 14th

The East Middlesex Mosquito Control Project (EMMCP) is planning to conduct mosquito control activities in specific areas of Bedford on Tuesday, July 14, 2020. All spraying is done between dusk and 11:30 PM.

EMMCP will use a truck mounted aerosol sprayer to apply Sumithrin in areas of Bedford that are located in the vicinity of Concord Rd., Davis Rd., Carlisle Rd., North Rd., Wildwood Dr. and Pine Hill Rd.

If postponed, the truck mounted spraying will be rescheduled for the week beginning July 20, 2020.

In the truck mounted sprayers, EMMCP 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 dusk.

Additionally on the evening of July 14th, EMMCP will spray the treelined areas surrounding the fields at Bedford High School to control for mosquitoes. A product called Mavrik Perimeter will be applied by EMMCP staff using backpack sprayers. The spray is applied to the perimeter and not on fields so they can be used for activities with no interruption.

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