To effectively remove mice from walls, consider:
- Sealing entry points with caulk, steel wool, or expanding foam.
- Removing food sources by storing pet food and birdseed in airtight containers.
- Eliminating water sources by fixing leaks and removing standing water.
- Reducing shelter by removing clutter, cardboard boxes, and excess insulation.
- Trapping mice using snap traps or live traps baited with peanut butter or cheese.
