FRAMINGHAM – The East Middlesex Mosquito Control Project will use a truck-mounted aerosol sprayer to apply Sumithrin in Framingham on Thursday, September 12, 2019, between dusk and 11:30 p.m.
Spraying is scheduled for areas of Framingham that are located south of Waverly St., near Fay Road, Bethany Road, Winthrop Street, Hollis Street, Irving Street and Jodie Road.
If spraying is postponed, the area will be rescheduled for the week of September 16, 2019.
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.
The Massachusetts Department of Public Health raised the risk level for EEE in Framingham from HIGH to CRITICAL Friday, September 6.
The virus that causes EEE is spread through the bite of an infected mosquito. In Massachusetts, the virus is most often identified in mosquitoes found in and around freshwater swamps. EEE is a rare but serious and potentially fatal disease that can affect people of all ages.
