When winter hits North Texas, rodents begin searching for warm, dry places to take shelter—and your home might be their first stop. Even the most elegant properties can fall victim to infestations if vulnerable areas aren’t properly sealed. Identifying and closing off the most common winter entry points is essential to preventing rodents from turning your home into their winter retreat.
At Jacksons Mosquito & Pest Control, we work with high-end homeowners across the DFW area who want their homes protected from all angles. Whether you live in a gated estate, a lakeside retreat, or a family home in the suburbs, rodent access points can exist in the smallest, most overlooked areas. This guide outlines where rodents sneak in and how to secure these trouble spots before the cold drives them inside.
Why Rodents Target DFW Homes in Winter
Mice and rats don’t hibernate—instead, they actively seek shelter when temperatures drop. DFW winters may be mild compared to other parts of the country, but they’re cold enough to send rodents indoors. The warmth, shelter, and food sources inside a home make it irresistible.
Once inside, rodents can chew wires, nest in insulation, destroy valuables, and contaminate kitchens or attics. Because they reproduce quickly, a small problem can escalate into a full-blown infestation by early spring.
That’s why identifying winter entry points before the season hits is a critical part of winter home maintenance, especially for clients with second homes or limited year-round occupancy.
The Most Common Rodent Entry Points to Watch For
1. Garage Door Gaps
Garages are often overlooked, but they’re a favorite entry zone for mice and rats. Gaps along the bottom seal or side rails offer easy access—especially if the weatherstripping is worn out.
2. Rooflines and Eaves
Rodents, especially roof rats and squirrels, can scale trees and jump onto roofs. They enter through damaged shingles, uncapped vents, soffits, or even open attic louvers.
3. Foundation Cracks and Weep Holes
Small holes in the foundation or gaps in brick weep holes give mice a clear path into crawlspaces and wall cavities. These are among the most common winter entry points and are easily missed without a professional inspection.
4. Plumbing and Utility Penetrations
Wherever wires, pipes, or HVAC lines pass into the house, there’s a risk of gaps or unfinished sealing. These penetrations are ideal for rodents seeking quick access into walls or cabinets.
5. Chimneys and Flues
Uncapped chimneys are an open invitation to rodents, birds, and even raccoons. Always check that fireplace flues close tightly and that chimney caps are installed and secure.
6. Vents and Dryer Outlets
Any vent leading to the outside must be screened or sealed. Dryer vents, attic exhausts, and bathroom fan outlets are all vulnerable to rodent intrusion if left open.
How to Inspect and Seal Rodent Entry Points
Perform a Perimeter Check
Walk around your home’s exterior during daylight and look for small openings or chew marks. Use a flashlight at dusk to spot hidden gaps where light leaks through. Focus on corners, trim joints, and utility areas.
Use the Right Materials
Rodents can chew through foam and some plastics. For long-term exclusion, use rodent-proof materials like:
- Steel wool and caulk for small holes
- Concrete or mortar for foundation gaps
- Hardware cloth (1/4″ mesh) for vents and weep holes
- Heavy-duty weatherstripping for doors

Why Professional Sealing Is Worth the Investment
Rodents are crafty—and they only need an opening the size of a dime to get inside. Store-bought traps and sprays may catch a few pests, but they won’t stop the problem at the source.
