Re: Notice of Aerial Larval Control Application
In accordance with 333 CMR 13.04 (7) (a & b), please consider this as notification of the pending aerial application targeting mosquito larvae in the wetlands in the District.
The Norfolk County Mosquito Control District will be conducting helicopter applications of the biorational larvicide Bti (Bacillus thuringiensis israelensis) to control mosquito larvae. These applications will be conducted over specific large wetlands in the Towns of:
Avon/Bellingham/Braintree/Canton/Dedham/Dover/Foxboro/Franklin/
Holbrook/Medfield/Medway/Millis/Milton/Needham/Norfolk/Norwood/
Plainville/Quincy/Randolph/Sharon/Stoughton/Walpole/Westwood/
Weymouth/Wrentham
These applications will be conducted over a likely 2 to 4-day window, lasting only 2 days, anytime between April 12, 2021, and April 30, 2021. As always, the weather in the spring is unpredictable. For this reason, the District cannot pin down actual application dates with any more accuracy at this time. We will send out further notices as the application date approaches.
The trade name of the granular formulation of Bti to be used is VectoBac GR (EPA Reg. No. 73049-486) and VectoBac GS (EPA Reg. No. 73049-10). This is not a “spray”. For further information contact David A. Lawson, Director at (781) 762-3681 or the Boards of Health in the towns listed above. Information is also available on line at www.norfolkcountymosquito.org
Respectfully submitted
David Lawson
Director
