Those Aren't Mosquitoes

blackfly

Field Crews have begun to report that blackflies are now active. Although bothersome and they do bite, they do not transmit disease in Massachusetts, and we do not offer any control options for them. Repellents with DEET have been shown to be effective. Their lifespan is limited, only a few weeks in springtime.
