Rodent-Proofing Your Home Before Winter

By Raymond T. JacksonJuly 5, 2026

As temperatures drop, rodents seek warm shelter—often in your home. Mice can squeeze through openings as small as a dime, and rats can fit through a quarter-sized hole. Here's how to keep them out:


Seal All Entry Points

Inspect your home's exterior thoroughly:

- Foundation cracks

- Gaps around pipes and utility lines

- Damaged soffits and fascia

- Gaps under doors

- Holes in siding

- Chimney openings


Use the right materials:

- Steel wool (mice can't chew through it)

- Copper mesh

- Hardware cloth (1/4 inch)

- Caulk and expanding foam (with steel wool inside)


Remove Food Sources

- Store pet food in metal or glass containers

- Keep birdseed in sealed containers

- Clean up fallen fruit

- Store garbage in sealed bins

- Don't leave pet food out overnight


Eliminate Harborage

- Trim tree branches 10+ feet from roof

- Move firewood 20 feet from home

- Clear brush and debris from foundation

- Keep grass and weeds trimmed

- Remove clutter in garage and basement


Inspect for Signs

Look for:

- Droppings (rice-sized for mice, larger for rats)

- Gnaw marks on wood or wires

- Grease marks along walls

- Scratching sounds in walls at night

- Nests of shredded material


Professional Help

If you see one mouse, there are likely more. A professional can:

- Identify entry points you missed

- Set traps strategically

- Safely remove infestations

- Provide long-term exclusion solutions


Don't wait until rodents are inside—prevention now saves headaches later!
