Mosquito Spraying Planned For This Week In Hyde Park

​Tuesday, July 27, 2021 - The Boston Public Health Commission (BPHC) announced there will be an upcoming spraying to help control the mosquito population in the residential neighborhood nearby Fowl Meadow in Hyde Park. The recent rainfall has resulted in very high numbers of mosquitoes being found in surveillance traps. So far this year, mosquito samples have tested positive for West Nile Virus (WNV) in Jamaica Plain and Brighton.

  • Thursday, July 29, 2021: The Suffolk County Mosquito Control Project is planning to use a truck mounted sprayer to spray in the area of the Neponset Valley Parkway between Meadow Road and Prescott Street. All spraying happens between dusk and 11:30pm. If it is postponed, it will be rescheduled for next week.

As with any pesticide, people should minimize their exposure and close windows during this time. If residents see a spray truck approaching, go indoors for a few minutes while the spray dissipates. Beekeepers do not need to take any special precautions since spraying begins after dusk. 

The mosquito control product being used is Zenivex E4 (EPA Reg No. 2724.807). It is 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. Zenivex E4 biodegrades rapidly and doesn’t build up in the environment. If residents have any questions related to the spraying, they should call the Suffolk County Mosquito Control Project (SCMCP) at 781-899-5730. 

BPHC partners with the SCMCP to protect Boston residents from mosquito-borne illnesses and to control the mosquito population in certain areas of Boston. SCMCP collects mosquito samples in traps every week during the summer and fall. Those mosquito samples are tested to see if WNV or Eastern Equine Encephalitis (EEE) are present. Mosquito control measures are also implemented during the summer and fall months. Wetlands, storm drains and other areas around the city are treated to limit the number of mosquitoes by killing mosquito larvae. 

In April of 2021, there were sprayings in Hyde Park and West Roxbury. For more information about the sprayings, reach out to SCMCP at 781-899-5730. For a full list of any upcoming spraying, please visit

Mosquitoes in Boston are most active from dusk to dawn during the months of July to September. However, mosquitoes can spread disease until the first hard frost (as late as November). Mosquito species have different breeding habits, but most want to lay their eggs near water – usually in vegetation or in still water. To help prevent mosquitoes from breeding, BPHC advises residents to limit places around the home where standing water can collect. Residents should turn over unused flowerpots, buckets, wheelbarrows and garbage cans; remove leaves and other debris that can clog gutters and trap water; dispose of or cover old tires; and cover swimming pools when not in use.
