The Northeast Massachusetts Mosquito Control and Wetlands Management District expects to 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 between July 23 and July 31.
The material to be applied Bti is a natural bacterium found in soil and water. Bti 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, known as Vectobac, will be applied by helicopter flying low directly over the salt marsh.
Residents do not need to take any special precautions as the application will occur directly over the salt marsh and not in residential areas.
