Rodent Inspection & Control

Sewer Baiting Dead Rat Rodent Burrow Rat by Plant Neighborhood Survey

The Vector Control Program enforces rodent control under Berkeley Municipal Code (Chapter 11.32) by investigating all requests for service concerning rodents and rodent harborage and rendering appropriate services in response.

Property Inspection and Consultation

Requests for service from the public include not only complaints, but also requests from tenants or property owners for assistance in removing rodents or insects from their property. In response to the requests, the Vector Control staffs can conduct in-depth inspections, issue inspection reports, and provide consultation and recommendation to exclude, control, and prevent rodents.

In addition, the staffs provide identification services  and educate people on a one-to-one basis or in groups of tenants, neighborhood associations, or property owners via phone consulations, literatures, and outreach events. For on-line educational information on rodents, see Control & Prevention of Rodents.

Overgrown Vegetation & Rodent Harborage Issues

The Vector Control staffs also respond to requests for service concerning overgrown vegetation, trash, garbage and debris accumulations, which contribute to rodent harborage issues. See Waste Management for details regarding enforcement. 

Sewer Inspection & Baiting

The Vector Control staffs make a special effort to control Norway rats by monitoring sanitary sewers throughout the city. The staffs conduct periodic, regular inspection of sewer access covers and perform appropriate follow up treatment if rodent presence or activity detected.  Each year, a team of two or more Vector Control staffs inspect and bait over 1700 sewer manholes, as necessary. Vector Control Technicians are certified by the state and trained in safe handling of bait. 

In addition, the Vector Control staffs work closely in conjunction with the city Public Works Department to investigate, dye test, and repair broken sewer lines or laterals which may allow rats into neighborhood. The city Public Works staff routinely inspects sewers and reports evidence of rodent infestations to the Vector Control staff.

General Surveillance

The Vector Control staffs regularly conduct surveys and inspections throughout the city as a measure of surveillance for rodents and other vectors. The areas that are routinely surveyed and inspected include:

  • Neighborhood/Block
  • Waterfront/Shoreline
  • Parks
  • Vacant Lots

During the suvey, the staffs check for active signs of rodents, as well as sources of food, water, and harborage of rodents. If the staffs find evidences of rodent infestation or conclude that the area is at risk of potential rodent or other vector infestation, they will take necessary control measures.
