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, and any other new subscribing

community if requested. Applications will be conducted as necessary during daylight hours from April 1, 2026,

through October 31, 2026.

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. For further information contact Barry Noone, District Director of the

Northeast Massachusetts Mosquito Control and Wetlands Management District at (978) 352-2800.
