Common Nuisance Animals that Damage Walls and Concrete Foundations
Rodents (Rats & Mice)
Rodents are notorious for exploiting small gaps and causing big problems.
- Chew through wooden beams, weakening structural integrity
- Gnaw on foundation insulation, reducing energy efficiency
- Create entry holes that allow other pests to enter
Squirrels
Though often associated with attics, squirrels can be just as destructive in walls and foundations.
- Gnaw through wooden framing, causing structural damage
- Dig into foundation insulation for nesting
- Weaken structural beams by constant chewing
Raccoons
Raccoons are strong, persistent animals that force their way into walls and voids.
- Tear into walls to gain access to nesting areas
- Rip apart insulation, reducing thermal efficiency
- Scratch and chew through wooden supports, weakening the structure
Bats
Bats can quietly roost inside wall cavities and go unnoticed for long periods.
- Roost in wall cavities, leading to hazardous guano buildup
- Leave urine and feces stains that cause structural decay
- Squeeze through small cracks, enlarging openings over time
Opossums
Opossums seek dark, hidden spaces like wall voids and crawlspaces.
- Tear into drywall and insulation to create nests
- Leave droppings that contaminate walls and insulation
- Scratch and claw at wooden structures, causing damage
Skunks
Skunks don’t just smell bad—they can cause serious foundational issues.
- Dig burrows under foundations, leading to cracking and instability
- Release strong odors that absorb into walls and insulation
- Tunnel under concrete slabs, weakening structural integrity
Snakes
Snakes are quiet invaders that often slip into wall voids through foundation gaps.
- Enter through foundation cracks and expand openings
- Shed skins and leave waste inside walls
- Use insulation and voids inside walls as shelter
Carpenter Ants
Small but destructive, carpenter ants hollow out structural wood from the inside.
- Tunnel through damp wood, creating hollowed-out beams
- Weaken wooden wall supports, leading to potential collapse
- Leave behind frass (sawdust), signaling infestation
Woodchucks (Groundhogs)
These burrowers can compromise the very ground your home is built on.
- Dig large burrows under foundations, causing structural weakening
- Gnaw on wooden structures, leading to long-term damage
- Undermine concrete slabs, leading to cracks and shifting
