As mosquito season approaches, Blackstone and Millville residents can expect targeted mosquito control treatments throughout June.

How Mosquito Spraying Works
CMMCP uses a method called Ultra-Low Volume (ULV) spraying, which allows small amounts of diluted pesticide to be dispersed into the air as a fine mist — sort of like a giant aerosol can on the back of a truck.
These trucks use computer-controlled sprayers and typically move at 10–15 mph, allowing the mist to drift into areas where mosquitoes are most active. Spraying takes place in the evening, when mosquitoes are leaving wooded areas and moving into open spaces to feed.
Because of how the spray drifts, the trucks don’t need to drive into your backyard — the mist will naturally reach those areas. CMMCP does not go off paved or hard-packed roads to avoid private property and liability concerns.
You may start to notice a difference within a few days, but full effectiveness can take up to a week. If mosquitoes are still a problem, you can always submit another request for service.

💧 Notice an abandoned pool? Standing water is a major mosquito breeding ground. If you spot an abandoned or neglected swimming pool, you can report it to the Blackstone Board of Health or contact CMMCP directly to help address the issue.
