The Massachusetts Department of Public Health and Department of Agricultural Resources have announced plans for additional aerial spraying to combat mosquitos carrying the Eastern Equine Encephalitis (EEE) virus.
Communities that are scheduled to be partially or fully sprayed beginning on Sept. 10 and into next week include:
- Norfolk County: Bellingham, Franklin, Medway, Millis, Norfolk, Medfield, Walpole, Wrentham, Foxborough, Sharon, Norwood, Westwood, Dover, Needham, Wellesley
- Middlesex County: Ashland, Hopkinton, Holliston, Sherborn, Framingham, Natick, Wayland, Sudbury, Maynard, Stow, Hudson, Marlborough, Weston
- Worcester County: Berlin, Boylston, Northborough, Westborough, Shrewsbury, Grafton, Upton, Milford, Hopedale, Mendon, Blackstone, Millville, Uxbridge, Douglas, Northbridge, Sutton, Millbury, Auburn, Oxford, Webster, Southborough, Bolton, Clinton, West Boylston, Worcester, Charlton, Dudley, Leicester, Harvard
According to the town:
While the Town of Wellesley remains at a low risk level for EEE, a portion of the Town is located in the defined spray path and will be sprayed at night, between the hours of 7:15 p.m. and 4:30 a.m., sometime within the next five to six days. The specific areas impacted will be in the 02482 zip code and the western edge of the 02481 zip code. Morses Pond and Lake Waban, both open bodies of water, will be excluded from spraying as will Fuller Brook and other tributary streams.
Here’s a map showing which part of Wellesley will be in the spray zone. You can plug an address into this interactive map to get more specific spray coverage info.


The town of Wellesley issued an update on EEE on Monday, saying it had no plans to spray but that things could change based on risk levels. Concerned citizens had been circulating a petition/letter urging town officials to spray sooner than later.
Residents with specific questions and concerns about EEE and aerial spraying should contact the Massachusetts DPH 24-hour hot line at 617-983-6800.
