Start low, then inspect the full exterior
Door bottoms and foundations matter, but mice can also use utility lines, siding transitions, vents and roof-level gaps.
- Use a bright light and inspect slowly
- Check attached garages first
- Photograph openings for repair planning
Remove easy food and nesting material
Seed, pet food, recycling residue, cardboard and clutter can support activity after mice enter.
- Use durable sealed containers
- Keep storage off the floor
- Clean safely after documenting evidence
Monitor after repairs
A quiet night does not prove the problem is gone. Monitoring helps confirm whether fresh droppings, gnawing or captures continue.
- Date each inspection
- Do not disturb professional devices
- Schedule follow-up when new signs persist
