EEE Spraying Notice

Good morning Northbridge families,

We just received an alert from the state that the Massachusetts Department of Public Health and the Massachusetts Department of Agricultural Resources announced that, due to the risk of EEEv in Worcester County, an aerial pesticide application will be taking place in Northbridge. 

As such, the school district is required to provide families with Standard Written Notification, a Chemical Specific Fact Sheet, and a Consumer Information Bulletin.  These documents are attached to this email and also available on the District website at 

This spraying is aimed at reducing mosquito populations to limit the incidence and spread of EEE infection. You can find and read the press release at:

This application is scheduled to begin on Sunday evening (weather depending), August 25th, in Northbridge and several other towns in Worceter County and be completed by August 26th (tentatively).   

Spraying does not completely eliminate risk, however, and we continue to emphasize that residents use EPA-approved bug spray, wear long sleeves and pants to cover exposed skin, and cancel outdoor activities during the evening hours when mosquitoes are most active.

There are no health risks expected during or after spraying and there is no evidence that aerial spraying will exacerbate certain health conditions such as asthma or chemical sensitivity. No special precautions are recommended; however, residents can reduce exposure by staying indoors during spraying. Aerial spraying is not expected to have any impacts on surface water or drinking water.

Aerial spraying will be conducted in the nighttime hours when fish are less likely to be at the surface feeding and honeybees are most likely to be in their hives. However, owners should cover small ornamental fishponds during the night(s) of spraying. While it is not necessary to bring animals indoors during spraying, keeping pets inside will minimize the risk of exposure.

Although the aerial spray is considered necessary to reduce human risk, it will not eliminate it. Residents must continue to protect themselves from mosquito bites by staying indoors during peak mosquito hours, applying insect repellent when outdoors, draining standing water where mosquitoes breed, and repairing screens in doors and windows. Residents should also take steps to protect their domestic animals from mosquito bites.
