Truck Mounted Aerosol Mosquito Spray Schedule

For the week beginning September 10, 2018 the East Middlesex Mosquito Control Project is planning to use truck mounted aerosol sprayers to apply Sumithrin in Framingham between dusk and 11:30.

On Monday, September 10th, 2018, spraying is scheduled for areas of Framingham including roads north of Edmonds Rd. and west of Callahan State Park.

On Tuesday, September 11th, 2018, spraying is planned for neighborhoods of Framingham located in the vicinity of Hemenway Rd., Eaton Rd., Mayflower Rd., Joseph Rd. and Elm St.   

If spraying is postponed on either date, it will be re-scheduled for Wednesday, September 12th.   

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 dusk.

If residents have any questions related to mosquitoes or mosquito control, contact the East Middlesex Mosquito Control Project at 781-899-5730. Information on the spray schedule is available at the Project website at

Earlier this month, the Massachusetts Department of Public Health elevated the West Nile Virus risk level to moderate statewide. There have been human cases of WNV but NONE in Framingham. The expanding and intensifying positive mosquito findings are consistent with statewide levels. The majority of WNV human cases occur during August and September. The Health Department urges residents to take personal protective activities to avoid mosquito bites including: 

  • Schedule outdoor events to avoid the hours between dusk and dawn, when mosquitoes are most active.
  • When you are outdoors, wear long pants, a long-sleeved shirt and socks.
  • Use a repellent with DEET (but should NOT be used on infants under two months of age and should be used in concentrations of 30% or less on older children.
  • Keep mosquitoes out of your house by repairing any holes in your screens and making sure they are tightly attached to all your doors and windows.
  • Remove areas of standing water around your home.
