Every fall it happens the same way. The nights start cooling off, and mice and rats start shopping for a warm place to spend the winter. In Metro Atlanta that usually means your attic, your crawlspace, or your garage — anywhere with shelter, quiet, and a way in.
Here’s the part most homeowners miss: rodents don’t chew their way in through the wall like in the cartoons. They walk in through gaps that are already there. A mouse fits through a hole the size of a dime. A rat needs one about the size of a quarter. Your house almost certainly has a few.
This checklist is what we’d look at on an inspection. Walk through it one afternoon before the real cold sets in and you’ll make your home a much harder target.
1. Seal gaps around pipes, vents, and utility lines
Walk the outside of your house and look everywhere a pipe, cable, or vent passes through the wall — AC lines, hose bibs, dryer vents, cable entries. If you can see daylight around it, that’s an entry point. Seal small gaps with caulk or copper mesh; use hardware cloth (not chicken wire) over larger openings around vents.
2. Check the garage door seal
Close the garage door and look along the bottom and sides. If you see daylight, a mouse sees a front door. Replace worn weatherstripping and make sure the side seals sit flush against the door.
3. Cap the chimney and screen the roof vents
An uncapped chimney is an open invitation for squirrels and raccoons, not just rodents. A basic chimney cap and intact screens over attic and roof vents close off the two most common wildlife entry points we see in fall.
4. Trim branches back from the roof
Squirrels don’t need a ladder — they need a branch within jumping distance. Trim limbs so nothing hangs within about six feet of the roofline. While you’re at it, cut back bushes and shrubs touching the siding; they give rodents cover right up against the house.
5. Move the firewood pile
Firewood stacked against the house is a rodent hotel with room service. Move it at least 20 feet from the house and keep it stacked off the ground.
6. Lock down the food sources
Trash cans with tight-fitting lids, pet food picked up at night (not left in the bowl on the porch), bird feeders kept away from the house, and fallen fruit cleaned up. Rodents follow the food — remove it and your house drops down their list.
7. Declutter the attic, basement, and crawlspace
You don’t need to throw everything out. But cardboard boxes, old fabric, and stored clutter are nesting material, and a packed storage area hides droppings and gnaw marks until the problem is big. Clear enough space that you can actually see the floor and the corners.
8. Inspect the crawlspace door and foundation vents
Crawlspace access doors warp and foundation vent screens rust out. Push on them — if one moves, bends, or has a gap, it’s not keeping anything out. This is one of the most common entry points we find on fall inspections.
9. Check weatherstripping on every exterior door
Run your hand around each exterior door frame. If you feel air, or the stripping is cracked and brittle, replace it. Doors are the entry point people check last and rodents check first.
10. Flashlight-check the attic
Pop your head into the attic with a good flashlight and look along the edges and corners for droppings, gnaw marks on wood or wiring, and nesting material like shredded insulation or paper. Finding signs now — before nesting season is in full swing — makes the fix faster and simpler.
Already hearing scratching at night?
Then you’re past the prevention stage — something’s already moved in. I wrote up what those sounds usually mean and what to do about them here: Hearing Scratching in Your Attic? What It Means and What to Do. Don’t wait it out; they don’t leave on their own.
