Can Rats and Mice Chew Through Walls?
Short answer
Yes. Rats and mice can chew through wood, drywall, plastic, foam, wiring insulation and thin aluminum. They cannot chew through steel mesh, hardware cloth, sheet metal or cement patch.
What they can chew
- Wood and drywall
- Plastic pipes and wire coverings
- Expanding foam and caulk
- Weather stripping and thin vents
What stops them
- Quarter inch galvanized hardware cloth
- Stainless steel wool packed with sealant
- Sheet metal flashing
- Cement based patch for cracks
Why it matters
Chewed wiring is a fire risk, and chewed insulation and pipes cause damage and energy loss.
