Effective immediately, to ensure the public’s heath, all Town owned outdoor properties REMAIN closed between the hours of 6:00pm and 6:00am.  These closures will remain in effect until the Town issues an official notification that the health risk has subsided.

For all non-public spaces, SEMA strongly recommends that residents take precautions when outdoors and limit outside activities during common times and environments with mosquito activity, especially at dusk, dawn and in swampy and wooded areas.

Massachusetts Department of Public Health/Massachusetts Department of Agricultural Resources announced aerial spraying for mosquitos will take place in portions of Middlesex, Norfolk and Worcester counties, beginning Tuesday September 10, 2019 after dark and will continue over several evenings.  Spraying is weather dependent and will cover all of Southborough.   Link below provides updated information on when an area has been sprayed, as well as other FAQ's and pertinent fact sheets.

  • Use mosquito nets on baby carriages;
  • Make sure that all your screens are in good repair and that all openings to the outside are equipped with screens or kept closed;
