Summary

Property owners across San Bernardino County must keep premises free of rodent harborage, and Public Health may abate severe infestations on private land at the owner cost.

Full Breakdown

Under the SBC Code and California Health and Safety Code, owners and tenants must maintain buildings and yards in conditions that do not harbor rats, mice, or disease-carrying vectors. Stored materials, woodpiles, and trash must sit off the ground. After complaints, the Mosquito and Vector Control Program inspects, posts notice, and may enter and abate. Plague surveillance is active in the San Bernardino Mountains and high desert near Big Bear and Lake Arrowhead, where ground squirrels and chipmunks pose elevated risks.

Violations & Fines

Failure to abate after written notice can lead to county abatement, lien on the property, and administrative fines up to 500 dollars per violation.

Frequently Asked Questions

What attracts rodents in the desert?

Open compost, pet food left outside, leaky irrigation, dense oleander hedges, and stored lumber. Sealing gaps larger than a quarter inch around the home foundation is the most effective control.

Who handles ground squirrels at cabins?

Owners are responsible. Vector Control will inspect free of charge if plague is suspected and may apply flea treatments to burrows during active surveillance seasons.
