MOSQUITO CONTROL

Mosquito banner.jpg
Mosquito-borne illnesses are spread to people by the bite of an infected mosquito. Examples include West Nile virus (WNV) or Eastern equine encephalitis (EEE) virus. Typically, the season for West Nile virus or other mosquito-borne illnesses in Boston is summer through early fall. The current risk for WNV in Boston is high.

The Boston Public Health Commission (BPHC) partners with the Suffolk County Mosquito Control Project (SCMCP) to protect Boston residents from mosquito-borne disease transmission. The SCMCP collects mosquito samples (mosquito collections) in traps every week during the summer and early fall. These traps are located throughout the city. The samples are tested at the Hinton State Laboratory to determine if WNV or EEE virus is present.

Information from mosquito collections, including the number of mosquitoes present, helps to determine where extra precautions are needed to keep Boston residents safe. This may include truck mounted aerosol spraying to control adult mosquito populations.

If mosquito spraying is required, it will be completed between dusk and 11:30 PM on scheduled days in targeted areas of the City (see below). Mosquito spraying is subject to weather and may need to be rescheduled. SCMCP advises that if people see a spray truck approaching, they should go indoors for a few minutes. Residents are also advised to close any windows that face the street during scheduled spraying. Information on the larvicide is available at EPA.gov.

Process to Exclude Property from Mosquito Control and other Public Area Wide Pesticide Application
Residents can file to have their property excluded from spraying at any time of the year.  Filing to exclude a person's property can be done electronically through the Massachusetts Department of Agricultural Resources (MDAR) or by sending an exclusion form through the mail to MDAR.  Questions regarding the exclusion process can be answered by calling Juan Carlos Gutierrez at the MDAR at 617-626-1723 or by emailing Juan.Gutierrez@state.ma.us
