The Andover Health Division was notified on Aug. 16 that two mosquito pools in the Abbot Street area tested positive for the EEE virus. The mosquitoes tested were trapped on Aug. 13 and were of a species that is known to bite humans. To address the mosquitoes, the Northeast Massachusetts Mosquito Control and Wetlands Management District will conduct spraying in the area on Tuesday, Aug. 20 between the hours of 8-11 p.m. If there is inclement weather, the spraying will be postponed one day.
The area being treated is bounded by Andover Street from Central to Woburn St., Woburn Street from Andover St. to Spring Grove Road, Spring Grove to Abbot Street, to Eastman Road, and Abbot Bridge Drive, and all streets inside this boundary. Additionally, the town and District are working together to conduct barrier spraying along town-owned athletic fields.To view the map of where mosquito spraying will occur click here.

The District offers the following tips for residents ahead of spraying:
As an initial response to positive tests, the Northeast Massachusetts Mosquito Control and Wetlands Management District is deployed a supplemental mosquito trap to the area this weekend.
The Andover Board of Health will meet Monday evening to discuss the positive test results. It is anticipated that adult mosquito spraying from truck based applicators will occur in a targeted area on Tuesday night or Wednesday if there is rain on Tuesday. A state entomologist will also attend the Board of Health meeting as a resource.
