The East Middlesex Mosquito Control Project will be controlling mosquitoes in neighborhoods of Sudbury using truck mounted aerosol sprayers on Wednesday, June 20th and Thursday, June 21st.  All spraying is done between dusk and 11:30 PM. 


On Wednesday, spraying is scheduled for neighborhoods that are located near Landham Rd., Woodside Rd., Raymond Rd., Dudley Rd., Goodman’s Hill Rd. and Indian Ridge Rd.


On Thursday spraying is scheduled for streets that are located near Dakin Rd., Powers Rd., Powder Mill Rd., Pantry Rd., Haynes Rd., Mossman Rd., Willis Rd., Ford Rd., Maynard Rd., Fairbanks Rd., Moore Rd. and the Pine Lakes neighborhood.


The Project uses a spray formulation containing the pesticide, sumithrin, to control mosquitoes.  Sumithrin is a synthetic pyrethroid that is classified as slightly toxic by the EPA.  Mosquito control applications of sumithrin do not pose a significant risk to people or their pets due to the low toxicity of sumithrin and the small amount used to control mosquitoes.  As with any pesticide, people should minimize exposure.  If residents see a spray truck approaching, they are advised to go indoors for a couple of minutes while the spray dissipates.  Residents are also advised to close windows facing the street.


Information regarding the schedule and areas to be sprayed is available via a recorded message at 781-893-5759 and at the Project’s website at   If residents have any questions related to the spraying or any questions on mosquitoes, call the East Middlesex Mosquito Control Project at 781-899-5730.
