[ARCHIVED] State Aerial Mosquito Spray Update

News Logo

Aerial spraying for mosquitoes has not yet occurred in Wellesley. 

The Health Department is reminding residents to close windows and doors and turn off window air conditioners and fans at night. 

The spray product decomposes in light and air so windows, doors, fans and air conditioners may be re-opened and used during the daytime.

As the spraying is weather dependent, the Massachusetts Department of Agricultural Resources (MDAR) cannot provide exact times and days that communities in the defined area will be sprayed. 

MDAR's interactive spray map is updated each day after spraying takes place. Residents can enter addresses to see areas where spray was applied.  

Wellesley will only be sprayed one night. Spray planes fly at relatively low levels and may make a few passes as they cover the area. 

Detailed information about the spraying is available on the Massachusetts Department of Public Health (MDPH) website

Questions may also be directed to the MDPH 24-hour hotline at 617-983-6800.

Wellesley remains at a low risk level for the mosquito-borne disease Eastern Equine Encephalitis (EEE).
