Mosquito Spraying Coming To Sudbury As West Nile Samples Rise

SUDBURY, MA — The East Middlesex Mosquito Control Project will soon begin August pesticide spraying in residential areas to control the bloodsuckers as samples of West Nile virus have been confirmed across the state.

This week's truck-mounted spraying in Sudbury will take place Wednesday between sunset and 11:30 p.m. The spraying will take place along Landham Road, Woodside Road, Raymond Road, Nobscot Road, Goodman’s Hill Road, Old Lancaster Road, Rice Road, Horse Pond Road, Codjer Lane and Tall Pine Drive.

In recent weeks, state health officials have confirmed 21 positive samples of West Nile in mosquitos collected in traps across the state, including in Waltham, Boston, Brookline and Worcester, where two sample have been found.

The risk of humans contracting West Nile is "low" across the state except in Suffolk County and Waltham, Belmont, Watertown and Brookline, where the risk is "moderate."

The EMMCP uses a product called Zenivex E4 to kill adult mosquitoes. Officials say the pesticides used to control mosquitoes pose a low risk of harming humans and pets. But the mosquito control project still advises people to remain indoors, close windows and doors turn off window air conditioners and fans when trucks are present. Residents should allow between 15 and 20 minutes to pass after the spraying truck leaves before going back outside

Spraying is weather-dependent, and will be rescheduled next week if it's raining.
