Pest and Rodent Management

The Environmental Sanitation Division works to proactively prevent rodent infestations in the following ways:

  • Integrated Pest Management (IPM) Reports
  • Distribution of educational material about mosquitos and rodents
  • Construction Plans:
    Permitted construction
    Boston Water and Sewer Commission (BWSC)
    Massachusetts Bay Transportation Authority (MBTA) Construction
  • Seasonal baiting and trapping campaigns

Documenting Rodent Sightings

Upon receiving a complaint, a Health Inspector will conduct a full comprehensive inspection of the property and affected area. During this walkthrough the inspector will attempt to identify the food source and the exact area of infestation and activity.


Rodenticides are baiting mechanisms used to kill rats, mice and any other rodents. These pesticides come in different variations such as:

  • Liquids
  • Pellets
  • Dust
  • Blocks (which can only be purchased by a licensed pest control operator)

Most rodenticides are placed sub surface, covered securely, in locations where particularly heavy activity occurs, such as:

  • Rodent burrows
  • Sewer systems
  • Construction sites
  • Public alleys


Trappings are done all year round particularly during the change of seasons known as “breeding seasons.” Traps are typically placed on public properties such as parks, public streets, and alleys.

Integrated Pest Management (IPM)

An IPM program utilizes all suitable control methods to keep pests populations below the economic injury level. Methods include cultural practices, use of biological, physical and genetic controlled agents and the selective use of pesticides.
