Rodent Prevention and Control

Think you have a rodent problem?

The District CANNOT conduct trapping or baiting on residential properties, but we CAN:

Inspect homes and businesses for evidence of rodent infestation
Provide an impartial written report on evidence of rodent infestation and any needed actions
Provide education and advice on controlling and excluding commensal rodents
Provide presentations and training for groups and organizations

The information our trained technicians provide is free and can help reduce costs relating to rodent control. If you wish additional assistance with baiting and trapping, please contact a licensed pest control company.

In some cities, the District may already be conducting rodent control in creeks and public areas. For more information about this, please contact the District office by calling 650-344-8592 or emailing info@smcmvcd.org.

Rodent Prevention

Rodents are very clever about entering your home, but there are some common entry points that you can keep an eye out for. Be aware that any gap greater than ¼ inch could potentially admit a rodent, so look closely when you do an inspection!

Rodent Trapping and Chemical Control

Trapping and chemical control (also called baiting or rodenticiding) will only temporarily control rodents if no rodent proofing is done. Trapping and chemical control of rodents should be done after rodent proofing is completed.

The mite has 8 legs - two pairs are on the front end of its body and two pairs are on the back end.

Rat Mites
