As temperatures start dropping in September and October across northeast Georgia, something predictable happens: pests that spent the summer outdoors start looking for somewhere warm to wait out the winter. Mice, rats, cockroaches, stink bugs, spiders, and even the occasional snake will exploit any opening they can find to get into your home.
The good news is that most of these invasions are preventable. Fall is the best time to do a thorough exclusion check before the real cold sets in.
Walk Your Foundation
Get down low and inspect your entire foundation line. You’re looking for:
- Gaps where utilities enter: Pipes, electrical conduit, cable lines, and AC refrigerant lines all penetrate the foundation or exterior walls. Even a gap the diameter of a pencil is enough for a mouse.
- Cracks in the foundation itself: Hairline cracks can be sealed with concrete caulk. Larger cracks should be evaluated structurally and sealed.
- Gaps under doors: A mouse can squeeze under a door with a ¼-inch gap. Check exterior doors, garage doors, and crawlspace access doors. Replace worn weatherstripping.
- Weep holes in brick: Necessary for drainage, but can be covered with a coarse steel mesh to prevent entry.
Check Your Roofline
Rodents, especially roof rats and squirrels, enter from above more often than from ground level. Walk the perimeter of your home and look up:
- Gaps at the soffits and fascia
- Where the roof meets the chimney or any dormers
- Vent screens (attic vents, gable vents, roof vents), screens should be intact with no tears or gaps
- Tree limbs touching or overhanging the roof, these are bridges. Trim them back at least 6 feet.
Seal and Caulk
Hardware stores carry several products for sealing pest entry points:
- Expanding foam: Good for large voids but rodents can chew through it. Use it as a backer, not a final seal.
- Copper mesh or steel wool: Pack into gaps before sealing with foam or caulk. Rodents can’t chew through it.
- Exterior caulk: For smaller gaps around window frames, door frames, and utility penetrations.
- Sheet metal flashing: For larger gaps at the roofline or around foundations.
Reduce Harborage Around Your Home
Pests don’t appear from nowhere, they move in from adjacent harborage areas. Reducing attractive habitat near your home reduces pest pressure on it:
- Move firewood piles at least 20 feet from the house and elevate them off the ground
- Keep mulch beds thin (2 inches max) near the foundation and pull them away from the siding
- Remove leaf piles, debris, and clutter from around the foundation
- Keep grass trimmed back from the house
Inside the House
- Seal gaps under sinks where pipes enter cabinets
- Check behind the refrigerator and stove, these appliances generate heat and attract roaches
- Store pantry staples in hard-sided airtight containers (bags and cardboard boxes are easy for rodents and roaches to access)
- Fix any leaky faucets or pipes, moisture attracts cockroaches, silverfish, and other pests
When to Call a Professional
DIY exclusion handles a lot, but professional pest control adds two things you can’t replicate on your own: a trained eye that spots entry points you’ll miss, and a perimeter treatment that creates a chemical barrier pests cross at their own risk.
A fall perimeter treatment from Kilz Pest Control targets the insects most likely to overwinter in your walls, cockroaches, spiders, silverfish, and the occasional earwig, before they get established.
