By the time the first cold snap hits the Blue Ridge, rodents across Asheville are already scouting houses, garages and cabins for winter quarters. Mountain homes sit close to woods, creeks and open slopes full of mice, voles and squirrels, so the supply of potential intruders never runs out. The result is a pattern of calls that starts around October and runs well into spring.
Who is in the walls
House mice and white-footed mice are the most frequent invaders, small enough to get through gaps about the size of a dime. Norway rats occur in the older core of the city, around dumpsters, restaurant alleys and the creek corridors, and roof rats are less common this far inland. Squirrels and flying squirrels also take up residence in attics and soffits, and are often confused with rats. Bats occasionally roost in eaves, which requires a different kind of professional help and specific legal protections.
Signs to watch for
- Droppings in kitchen drawers, pantry shelves, attic corners or along sill plates.
- Scratching at dusk or dawn in walls or ceilings.
- Chewed food bags, soap, candles or insulation.
- A musky smell in enclosed spaces.
- Gnawed wires, which can create a fire hazard.
Why Asheville structures are easy to enter
Many older homes in Montford, West Asheville and Kenilworth have stone or brick foundations with cracks, ventilation openings, cellar doors and porches built over open crawl spaces. Mountain cabins and rustic additions often have rough sheathing, wide eave gaps and wood stacked against walls. Hillside homes in places like Haw Creek frequently have a basement door at grade level on one side that does not seal well. In the River Arts District and downtown, restaurants and older commercial buildings add food waste and shared walls, which draw rats.
What a rodent professional does
Technicians start by locating droppings, rub marks and openings, then set traps in travel paths and in attic or crawl spaces as needed. Poison is used sparingly and in tamper-resistant stations, especially where pets or wildlife could be harmed. The permanent solution is exclusion: packing gaps with steel wool or copper mesh and sealing with sheet metal or masonry patch, screening foundation vents, and adding door sweeps. When insulation is soiled, a cleanup and replacement may be recommended.
Cabins, outbuildings and second homes
Part-time mountain residences are especially vulnerable because nobody is home to hear the first sounds. If you close up a cabin for the winter, remove all food, store linens in sealed bins, and have a provider check the structure for gaps first. Garages, sheds and detached workshops around Asheville often shelter mice that later move into the main house.
Keeping them out all winter
- Seal gaps larger than a pencil around pipes, wires and vents before October.
- Store firewood off the ground and some distance from walls.
- Keep birdseed, pet food and grass seed in hard containers.
- Prune branches so they do not reach the roof.
- Check crawl space doors and basement windows for gaps.

Why do I hear scratching only at night?
Mice and rats are mostly nocturnal. Daytime noise is more often squirrels.
Is it safe to clean up mouse droppings myself?
Wear gloves and a mask, dampen the area with disinfectant, and wipe rather than sweep. Heavy contamination is better left to professionals.
Why do mice come back each year?
Because the same openings remain. Rodents leave scent trails that attract new animals until entry points are fully closed.
