As Alberta’s winter approaches, rodents begin looking for warm places to spend the season. Your home can be an ideal shelter, offering food, warmth, and protection from the cold. Mice and other small animals are surprisingly good at finding ways inside, often through openings as small as a dime. Once indoors, they can contaminate food, chew through wires, and damage insulation or belongings. That’s why now is the perfect time to rodent-proof your home before the cold weather sets in.
Why Rodents Move Indoors in Winter
Rodents stay active year-round, so they must find shelter to survive Alberta’s freezing temperatures. When food becomes scarce outdoors, they start seeking warmth and easy access to shelter. Attics, garages, basements, and kitchens offer everything they need to stay safe and hidden. These spaces are often quiet and rarely disturbed, making them perfect for nesting. Once rodents find a way in, they tend to stay and multiply quickly.
They commonly enter through:
-
Cracks in the foundation
-
Gaps around doors or windows
-
Openings around utility pipes and dryer vents
-
Loose soffits or damaged rooflines
-
Garage or patio doors left slightly open
Even small structural gaps can be enough to let mice inside. A full perimeter inspection before winter can help prevent future issues.
Signs You May Already Have Rodents
The earlier you detect rodents, the easier they are to control. If you know what to look for, you can often catch the problem before it gets worse. One of the first signs is droppings, often found in kitchens, pantries, basements, or along baseboards. You may also hear scratching or scurrying noises at night in walls or ceilings. These sounds are a strong sign of rodent activity, especially after dark when they are most active.
Other signs include:
-
Chewed wires, wood, or food packaging
-
Small piles of shredded material, such as paper or fabric
-
Greasy smudge marks along walls or baseboards
-
A musty or sour smell in enclosed spaces
If you notice any of these, a professional inspection is a smart next step.
How to Rodent-Proof Your Home
Rodent-proofing doesn’t require a full renovation, but it does take thoroughness and attention to detail. The key is to eliminate access and reduce attractants. Begin by walking around your home and looking for obvious entry points. Seal any gaps, holes, or cracks using materials rodents cannot chew through, such as steel wool, caulking, or mesh.
Effective prevention steps include:
-
Seal entry points: Use caulk or mesh around pipes, vents, and foundation cracks
-
Install door sweeps and weather stripping: Close gaps under doors and around windows
-
Store food in airtight containers: Use glass or heavy plastic to prevent access
-
Keep your yard tidy: Trim shrubs, move firewood 20 feet from the house, and clear debris
-
Declutter basements and attics: Use sealed storage bins and keep items off the floor
These small changes can make your home much less appealing to rodents.
When to Call a Professional
If you see even one rodent, more are likely nearby. Rodents breed quickly, and a small problem can grow into a major issue in just a few weeks. While traps may help temporarily, they rarely solve the root problem. A professional pest control provider can identify where rodents are getting in and safely remove them from your home. They will also offer expert recommendations for long-term prevention.
Benefits of working with a pest control expert include:
-
Thorough inspections and custom prevention plans
