Northern and Central California's Basement & Crawlspace Wildlife Control Service

Your basement or crawlspace might not get much attention, but these hidden areas are common targets for wildlife and pests. At Critter Bros LLC, we’ve spent more than 50 years protecting homes from North and Central California against destructive intruders that thrive in these dark, enclosed spaces. Whether it’s rodents, raccoons, snakes, or woodchucks, we use humane, eco‑friendly techniques to remove wildlife, repair damage, and secure your property to prevent future problems. Your foundation deserves expert care—and that’s exactly what we provide.

Common Nuisance Animals that Damage Subbasement and Crawl Spaces

Rodents (Rats & Mice)

Rodents are common basement invaders and can multiply quickly if left unchecked.

• Chew on wires, creating a fire hazard

• Destroy insulation by nesting and urinating

• Contaminate surfaces with droppings and urine, spreading diseases

Squirrels

Though more commonly found in attics, squirrels often seek shelter in crawlspaces.

• Gnaw through wood and wiring, causing potential fires

• Tear apart insulation for nesting

• Create loud noises when running and scratching

Raccoons

Raccoons are persistent and powerful pests that exploit weak points in your foundation.

• Tear off shingles or soffits to gain access

• Destroy insulation and ductwork when nesting

• Carry diseases like rabies and roundworms

Bats

Basements and crawlspaces provide cool, quiet areas for bats to roost.

• Roost in crawl spaces, leaving behind hazardous guano

• Create high-pitched noises at night

• Carry diseases like rabies and spread histoplasmosis

Opossums

Opossums are notorious for turning basements into nesting zones.

• Tear apart insulation and wiring when nesting

• Leave droppings that carry bacteria and parasites

• Attract fleas and ticks, creating a secondary infestation

Skunks

Their burrowing and odor make skunks a major concern for homeowners.

• Dig under foundations, causing structural weakening

• Release a strong, lingering odor when threatened

• Carry rabies and other harmful diseases

Woodchucks (Groundhogs)

These large burrowers can compromise your home’s foundation from below.

• Dig large burrows under foundations, leading to cracks

• Gnaw on wood, damaging support beams and trim

• Contribute to soil erosion near structures

Protect your foundation from wildlife damage before it gets worse.

 Trustindex verifies that the original source of the review is Google. I’m currently in chemo and with that it leaves us being away from our home quite often. We discovered 5 skunks in our yard and Critter Bros sent a tech same day to help us! Professional, friendly, and quick responses. It was the last thing we wanted to deal with or had the time for, thanks for making it stress free for us. Highly recommend

 Trustindex verifies that the original source of the review is Google. No more backyard bandits! Apparently, I was running an all-you-can-eat buffet for raccoons — and they loved it. Critter Bros came in  — totally professional, super chill, and they knew exactly how to outsmart these furry burglars. Now my yard is peaceful and my garbage stays in the can. If you’ve got raccoons treating your place like their personal hangout, call these guys ASAP.
