Rodent Control & Exclusion in San Anselmo, CA

San Anselmo is one of Marin County’s most cherished towns — tree-lined streets, craftsman bungalows, a walkable downtown full of antique shops and coffee roasters, and a genuine neighborhood spirit. It’s also prime territory for roof rats. The mature oak and redwood canopy that makes San Anselmo so beautiful gives rodents a direct overhead highway into attics, soffits, and wall cavities. Done Right Rodent Proofing works throughout San Anselmo and the wider Ross Valley to permanently close off that access.

Why San Anselmo Homes Are Particularly Vulnerable

The housing stock in San Anselmo skews older — many homes were built before modern construction standards accounted for rodent exclusion. Gaps where plumbing enters the foundation, deteriorating vent screens, aging fascia boards, and open crawlspace vents are common entry points in the area’s character-rich but aging homes. Add the creek corridors along San Anselmo Creek and Sir Francis Drake Boulevard, and the surrounding open space of the Marin Municipal Water District lands, and you have sustained rodent pressure year-round.

Roof rats are the dominant species in this part of Marin. Unlike Norway rats, which burrow, roof rats climb — they move through trees, along fences, and across utility lines before entering homes at roofline level. Identifying and permanently sealing those high-up entry points requires specific expertise and materials. Traps alone will never resolve a roof rat problem if the structure remains open.

Our Process

Every engagement begins with a thorough inspection of the entire structure: roofline, fascia and soffits, foundation vents, plumbing and electrical penetrations, garage door seals, and any attached structures. We document every gap and prioritize by severity. Once the scope is clear, we seal every opening using professional-grade materials — galvanized steel screen, metal flashing, concrete, or lumber depending on what the location calls for. We never use spray foam or steel wool, which rodents can breach in minutes.

After exclusion, mechanical traps are placed and monitored every 3–5 days. We return on a schedule until activity stops and the home is confirmed rodent free. You don’t touch a trap, handle a rodent, or manage any part of the process — we take care of everything start to finish.
