Plymouth County Mosquito Control Project is a state agency overseen by the State Reclamation and Mosquito Control Board of the Commonwealth of Massachusetts.





Aerial spraying for mosquitoes


The Massachusetts Department of Agricultural Resources (MDAR), State Reclamation and Mosquito Control Board (SRMCB), and the Massachusetts Department of Public Health (DPH) announced on Saturday, August 8 that aerial spraying for mosquitoes will take place in specific areas of Plymouth County and a small part of Bristol County. Spraying is expected to begin on Monday, August 10, and continue over several evenings. However, the ability to spray is weather dependent and the schedule may change. So far this year, 12 communities in southeastern Massachusetts have been found by DPH to be at moderate to critical risk for the Eastern Equine Encephalitis (EEE) virus.

The 25 communities in the spray zone are Bridgewater, Carver, Duxbury, East Bridgewater, Halifax, Hanover, Hanson, Kingston, Lakeville, Marion, Mattapoisett, Middleborough, Norwell, Pembroke, Plymouth, Plympton, Rochester, Rockland, Wareham, West Bridgewater, and Whitman in Plymouth County, and Acushnet, Easton, Raynham, and Taunton in Bristol County. The exact locations where spraying will occur are subject to change, and the final spray map for each day of spraying will be available each morning ahead of the spray operations.
