FYI - Spraying for mosquitoes will take place in various areas of Waltham on Tuesday, September 14th

On Tuesday, September 14, 2021, spraying is scheduled for areas of Waltham located in the vicinity of Woodchester Road, Tracer Lane, Copeland Street, Brewster Road, Hibiscus Avenue, Miriam Road, Greer Street, Addison Road, Juniper Hill Road, Marlborough Road and Shirley Road. The East Middlesex Mosquito Control Project is planning to use a truck mounted aerosol sprayer to reduce mosquito populations. Spraying will be done between sunset and 11:30 PM.

The mosquito control product being used is Zenivex E4 (EPA Reg No. 2724.807), and it’s being applied at 1 oz per acre. Zenivex E4 is a non-ester pyrethroid and is classified by the EPA as a reduced risk pesticide. Mosquito control applications of Zenivex E4 do not pose a significant risk to people or their pets due to the low toxicity and the small amount used to control mosquitoes. As with any pesticide, people should minimize their exposure.  If residents see a spray truck approaching, they are advised to go indoors for a few minutes while the spray dissipates. Residents are also advised to close windows. Beekeepers do not need to take any special precautions since spraying begins after dusk. Zenivex E4 biodegrades rapidly and therefore doesn’t build up in the environment.

If residents have any questions related to mosquitoes or mosquito control, contact the East Middlesex Mosquito Control Project at 781-899-5730. The spray schedule can be found at the Project website at http://sudbury.ma.us/emmcp/

As a reminder, West Nile virus has been detected in mosquitoes in Middlesex & Barnstable County, including Waltham. This is higher than average. All residents are urged to take necessary safety precautions, including avoiding peak mosquito activity times: https://bit.ly/3BbKwzZ
