NEWBURYPORT — The Northeast Massachusetts Mosquito Control and Wetlands Management District will conduct a helicopter application of the biological larvicide Bti to control mosquito larvae over coastal salt marshes in Salisbury, Newburyport, Newbury, Ipswich and Rowley during daylight hours through Friday.
Bti, a natural bacterium found in soil and water, will be applied. Bti is a selective larvicide that is non-toxic to people, as well as fish, birds, bees and to virtually all insect species. Bti only affects mosquito larvae and a few closely related aquatic insects in the fly family. The Bti will be applied by helicopter flying low directly over the salt marsh. The product name of the Bti is Vectobac 12AS.
Residents do not need to take any special precautions due to the safety of Bti and because the application will occur directly over the salt marsh and not residential areas.
