The Central Massachusetts Mosquito Control Project will conduct mosquito spraying in the designated areas shown on the attached maps and street lists on Thursday, August 6, 2026.

The Central Massachusetts Mosquito Control Project sprays after sunset, generally from dusk until midnight.

Residents in the treatment area should:

Residents who wish to exclude their property from spraying should submit a request as soon as possible through the state’s pesticide exclusion process or call 508-281-6786.
