Spring Pest Prevention Checklist for Canadian Homeowners

As winter melts away across Canada, warmer temperatures bring more than blooming flowers. Spring is prime season for pests to emerge from hibernation and seek food and shelter in your home. Taking proactive steps now can save you from costly infestations later. Here is your complete spring pest prevention checklist.

Exterior Inspection

Start by walking around the outside of your home and checking for vulnerabilities:

• Foundation cracks: Mice can squeeze through gaps as small as a dime. Seal any cracks in your foundation with caulk or steel wool.
• Door and window gaps: Check weather stripping and replace worn seals. Install door sweeps on exterior doors.
• Roof and soffits: Inspect for damage from winter ice and snow. Repair any openings that could let in squirrels, raccoons, or bats.
• Vents and chimneys: Ensure all exterior vents have screens. Cap chimneys to prevent wildlife entry.
• Utility entry points: Seal gaps around pipes, wires, and cables entering your home.

Yard Maintenance

Your yard is the first line of defence against pests:

• Clear debris: Remove leaf piles, fallen branches, and old mulch near the foundation. These are hiding spots for insects and rodents.
• Trim vegetation: Keep shrubs and tree branches at least 60 cm away from your home. Overhanging branches are highways for ants and squirrels.
• Fix drainage: Ensure gutters are clean and downspouts direct water away from the foundation. Standing water attracts mosquitoes.
• Woodpile storage: Store firewood at least 6 metres from your home and elevated off the ground. Woodpiles harbour carpenter ants and termites.

Interior Preparation

Inside your home, focus on eliminating what attracts pests:

• Kitchen deep clean: Clean behind appliances, inside cabinets, and under the sink. Crumbs and grease attract cockroaches and ants.
• Food storage: Transfer pantry items to airtight containers. Check for expired products and signs of pest damage.
• Moisture control: Fix leaky faucets and pipes. Use dehumidifiers in basements and crawl spaces. Many pests, including silverfish and centipedes, thrive in damp environments.
• Declutter: Remove cardboard boxes from basements and garages. Replace with plastic storage bins. Cardboard attracts silverfish and provides nesting material for mice.

Pest-Specific Spring Tasks

Target the most common spring invaders in Canada:

• Ants: Watch for scout ants in kitchens and bathrooms. Clean trails with vinegar solution to disrupt scent paths.
• Wasps: Check eaves, decks, and play structures for early nests. Small nests can be removed safely in early spring before colonies grow.
• Mice: Set traps in garages, basements, and utility areas. Spring is breeding season and populations can explode quickly.
• Carpenter ants: Look for sawdust piles near wood structures. These ants become active as temperatures rise above 0°C.
• Cluster flies: These slow-moving flies emerge from wall voids in spring. Seal entry points and vacuum up stragglers.

When to Call a Professional

If you spot signs of an established infestation, such as multiple sightings, droppings, or structural damage, it is time to call a licensed exterminator. Professional spring inspections can also identify problems you might miss.
