The Massachusetts Department of Agricultural of Resources (“MDAR”), acting through its State Reclamation and Mosquito Control Board (“SRB”), along with the mosquito control districts/projects (“Projects”) located throughout the Commonwealth, work closely with the Department of Public Health (“DPH”) to ensure an early detection, warning, and response system is in place to manage mosquito populations and mosquito-borne illness in the Commonwealth.  Surveillance has become the cornerstone of much of our control efforts. During each mosquito season, Projects, along with DPH, monitor for mosquito-borne viruses in order to be able to respond quickly, before the onset of human illnesses. The scope and method of mosquito control differs from each Project, due to differences in geographic location, habitat, topography, mosquito species present, and preferences of the residents in that region. While some Projects are restricted to surveillance, others employ control methods including larviciding, wide area pesticide applications to control adult mosquitoes, catch basin management, and ditch management or other mechanical methods to reduce mosquito habitat.

Under 333 CMR 13.03 links to PDF file, an exclusion request may be made to opt out of pesticide applications performed by a Project, or any other individual making a wide-area application as defined in 333 CMR 13.01 Requests must be submitted to MDAR either via first class mail or through an online form (currently under development). Exclusion requests may be submitted at any time during the year, and will go into effect 14 days from the date the request is made. All requests will expire December 31st in the calendar year in which they are received.

Once a request is received by MDAR, it will then be transferred to the Project that covers the region in which the property is located, if applicable. Properties to be exempted will be entered into a database designed to track excluded properties, which will be used by Projects during wide-area applications. A list of requests may also be made available to city and town clerks upon request.

Please be aware that this exclusion request process replaces the previous process by which requests were submitted to a city or town clerk by certified mail. If you have made a request in previous years and would like to continue to have your request recognized by a Project, please make sure to submit your request directly to MDAR using the methods identified here.

Approved Exclusion Marking Methods:
White plastic or aluminum pie plates, a minimum of 9 inches in diameter, with the words "No Spray" clearly written in permanent marker. Plates must be placed on trees, stakes, or poles easily visible from the street, at least every 50 feet along the property boundary adjacent to the road and no more than 5 feet from the road.
