As the temperatures drop and snow begins to fall, pests in Alberta start looking for warmth and shelter—often in your home. Winter may seem like a break from pest problems, but several insects remain active and can cause significant issues indoors. Knowing which pests to watch for and how to prevent them can save time, money, and stress. Use these winter pest prevention tips to protect your home from uninvited guests year-round.
Common Winter Pests in Alberta
While rodents are often the first concern during winter, several insects seek refuge indoors. Here are the key ones to watch for in Alberta:
Cockroaches thrive in warm, damp environments like kitchens, basements, and bathrooms. Once inside, they can spread bacteria, trigger allergies, and be notoriously difficult to eliminate.
Carpenter ants may appear less active in winter, but if they’ve built a nest in your home, they’ll continue tunneling through wood, potentially causing costly structural damage.
Cluster flies hibernate inside walls and attics during winter. While they’re more of a nuisance than a threat, their presence can be frustrating, especially if they emerge on sunny days.
Spiders often move indoors during winter. Though most are harmless, their webs can create an unsightly mess around your home.
Silverfish are moisture-loving pests that damage paper, fabrics, and food packaging. These insects are often found in damp areas like basements and bathrooms during winter.
Boxelder bugs seek warmth indoors when the weather cools. They typically cluster near windows and light sources. Although they don’t bite or damage structures, their presence can be bothersome.
Earwigs may enter your home in search of warmth and moisture. While primarily outdoor pests, they can become a nuisance in basements and bathrooms.
Pantry pests, such as grain beetles and flour moths, can infest stored food products. If they find a consistent food source inside your home, these pests remain active year-round.
How Pests Enter Your Home
Insects and other pests gain entry through small cracks, gaps, and openings. Common entry points are poorly sealed doors and windows, foundation cracks, and gaps around utility pipes. Once inside, they’re drawn to warmth, moisture, and food sources.
Practical Steps for Winter Pest Prevention
To protect your home, take proactive measures. Inspect the exterior of your home for cracks or holes and seal them with caulk. Pay close attention to areas around windows, doors, and pipes. Inside, keep living spaces clean and dry. Wipe counters regularly, store food in airtight containers, and promptly fix leaks. Use a dehumidifier in damp areas like basements to discourage moisture-loving pests.
If you store firewood, keep it at least 20 feet from your home and elevated off the ground. This reduces the risk of pests hitching a ride indoors. For homes with fireplaces, consider installing a chimney cap to block entry.
What to Do if You Spot Pests
If you notice signs of pests, act quickly. For isolated issues, traps, and natural remedies may suffice. However, for larger infestations, professional pest control services are often necessary. Regular home inspections can also help identify vulnerabilities and catch infestations early, saving you from bigger problems.
The Importance of Winter Pest Prevention
Preventing pests during winter is about more than comfort. Some pests, like carpenter ants, can cause structural damage, while others, like cockroaches, pose health risks by spreading bacteria and allergens. Taking preventive steps protects your home and contributes to a healthier living environment.
With a little preparation and vigilance, you can keep your home pest-free this winter and enjoy the season comfortably.
