Aerial Mosquito Control on Salt Marshes

AERIAL APPLICATION TO CONTROL MOSQUITO LARVAE ON COASTAL SALT MARSHES AND UPLAND HABITAT.

The Northeast Massachusetts Mosquito Control and Wetlands Management District will conduct helicopter applications of the biological larvicide, VectoBac12AS (EPA reg. 73049-38) to control mosquito larvae over salt marshes in Salisbury, Newburyport, Newbury, Rowley, and Ipswich. Applications will be conducted as necessary during daylight hours from August 10th through August 16, 2025. The material to be applied is a natural bacterium found in soil and water.

VectoBac12AS is a very selective larvicide with little or no effect on humans, pets, wildlife, pollinators, and most other beneficial insects. VectoBac12AS targets mosquito larvae and a few other closely related aquatic insects in the fly family. The VectoBac12AS will be applied by helicopter flying low and directly over the salt marsh and / or upland habitat. Residents need not take any special precautions due to the safety of VectoBac12AS and because the application will occur directly over wetlands.
