As the temperature drops in Calgary, pests like mice, rats, spiders, and cockroaches start seeking warmth — often inside your home.
What feels cozy to you is also cozy for them.
Winter pest infestations are one of the most common issues homeowners face, especially in older houses or those with small foundation cracks.
If you’ve ever noticed scratching noises in your walls or droppings near your pantry during winter, it’s a sign you need to pest-proof your home before the cold sets in.
Here are 10 proven tips from Xpeller Pest Control Calgary to help you keep pests outside where they belong.
Seal All Cracks, Gaps, and Openings
Even the tiniest gap can be an open invitation for pests.
Mice can squeeze through holes as small as a dime, and insects can crawl through wall or floor cracks.
What to do:
- Inspect your foundation, windows, and doors.
- Seal gaps with silicone-based caulk or steel wool for rodent-sized openings.
- Don’t forget utility lines, vents, and pipe entry points.
Xpeller’s technicians perform a detailed home inspection to identify and seal all possible pest entry areas.
Install Door Sweeps and Weather Stripping
Your doors and garage openings are common pest entry points, especially for mice and spiders.
What to do:
- Install door sweeps on all exterior doors.
- Replace worn-out weather stripping.
- Check garage doors for small gaps at the bottom.
This not only blocks pests but also saves on heating bills — a double win for Calgary homeowners.
Store Firewood Away From Your House
Firewood piles are a pest paradise — full of spiders, beetles, and even mice.
What to do:
- Keep firewood at least 20 feet away from your home.
- Store it off the ground on a raised platform.
- Only bring in wood when you’re ready to burn it.
Pro tip: Check firewood for insects before bringing it indoors.
Keep Your Kitchen Clean and Food Sealed
Pests need two things to survive: warmth and food.
The kitchen offers both — making it the #1 attraction for mice, ants, and cockroaches.
What to do:
- Store dry goods in airtight containers.
- Wipe counters, vacuum crumbs, and take out the trash daily.
- Don’t leave pet food overnight.
A clean kitchen is your first defense against infestation.
Declutter Your Basement and Attic
Rodents and spiders love dark, quiet spaces like basements, attics, and storage rooms.
What to do:
- Declutter old boxes, newspapers, and unused furniture.
- Use plastic bins instead of cardboard (pests love nesting in cardboard).
- Keep items off the floor.
Decluttering not only reduces hiding spots but also helps you spot early pest activity.
Trim Trees and Shrubs Near Your House
Overgrown branches touching your roof or walls act as bridges for pests like ants, rodents, and squirrels.
What to do:
- Trim all branches 2–3 feet away from your house.
- Clear leaves and debris near the foundation.
- Maintain your lawn to reduce nesting areas for outdoor pests.
Xpeller’s pest prevention service includes yard and perimeter inspection to keep outdoor pests from sneaking inside.
Inspect and Clean Gutters
Clogged gutters collect leaves and moisture — a perfect nesting site for insects and rodents.
What to do:
- Clean gutters regularly before heavy snow.
- Ensure downspouts direct water away from your foundation.
- Repair leaks to prevent damp areas that attract pests.
Check for Moisture and Fix Leaks
Pests need water as much as food. Leaky faucets, pipes, or damp basements attract silverfish, cockroaches, and rodents.
What to do:
- Fix leaky taps and pipes.
- Use a dehumidifier in damp areas.
- Improve ventilation in bathrooms and basements.
By keeping your home dry, you make it much less attractive to pests.
Schedule a Pre-Winter Pest Inspection
Even with DIY prevention, pests can hide in unseen areas — attics, crawlspaces, vents, and wall voids.
A professional inspection from Xpeller Pest Control in Calgary identifies potential threats before they become infestations.
Our experts use thermal imaging, bait stations, and safe eco-treatments to ensure your home stays pest-free all winter long.
