Where do most pests enter GTA homes?

Most pest entry points are at the foundation and roofline. Mice and rats enter through gaps in foundations, around utility lines, and where pipes enter the building. Ants enter through foundation cracks and around windows. Squirrels and raccoons enter through roofline gaps and soffit vents.

How do I pest-proof my foundation?

Walk your foundation perimeter in spring and fall. Seal any cracks with caulk or concrete patch. Seal gaps around gas lines, water pipes, and electrical conduit where they enter the foundation. Cover window wells with screens. Fill gaps wider than one-quarter inch.

What should I check on my roofline?

Inspect soffit vents for gaps and damage. Check roof penetrations around plumbing vents, chimneys, and HVAC units. Look for missing or damaged fascia boards. Seal any gaps between the roof and exterior walls. Trim tree branches back from the roof so squirrels cannot jump onto it.

How do I pest-proof my garage?

Install a door sweep on the garage door. Check and replace weatherstripping around the garage door frame. Install a fine mesh screen on any garage windows or vents. Keep the interior of the garage clean and free of food sources.

Q: What landscaping helps prevent pest problems?

Keep firewood stored at least 20 feet from your home and elevated off the ground. Trim tree branches so they do not touch or hang over the roof. Clean eavestroughs regularly so water does not pool near the foundation. Remove ground-level compost bins or keep them sealed.

By PestRecord Editorial Team

Most pest problems in GTA homes start at the boundary between your house and the outdoors. A gap in your foundation, a torn window screen, or a missing vent cover gives pests a direct entry point. Here is a complete checklist for pest-proofing your home from foundation to roofline.

Foundation

Walk the perimeter of your home twice a year, in spring and before winter. Look for:

Cracks in the foundation wall, no matter how small
Gaps around gas lines, water pipes, and electrical conduit where they enter the foundation
Damaged window well covers
Gaps wider than one-quarter inch at any point

Seal foundation cracks with concrete patch or epoxy. Seal pipe and conduit penetrations with caulk or expanding foam.

Roofline and Attic

Your roofline is the most common entry point for squirrels and raccoons. Inspect every spring:

Soffit vents: check for gaps, damage, and loose panels
Roof penetrations: seal gaps around plumbing vents, chimneys, and HVAC units
Fascia boards: repair any damage that creates gaps
Roof-to-wall junctions: seal any gaps
Tree branches: trim back so squirrels cannot use them to reach the roof

Doors and Windows

Install door sweeps on all exterior doors. Replace torn window screens. Check weatherstripping on all exterior doors and windows. Install fine mesh vent covers on any crawlspace vents.

Kitchen and Interior

Store dry food in sealed containers, not original packaging. Clean up crumbs and food spills immediately. Do not leave pet food bowls out overnight. Wipe down counters and sweep floors regularly. Empty the kitchen garbage daily.

Garage

Install a door sweep on the garage door. Check weatherstripping around the garage door frame. Screen any garage windows or vents with fine mesh. Keep the garage floor clean and free of food debris.

Landscaping

Store firewood at least 20 feet from your home and elevate it off the ground. Trim tree branches so they do not touch or hang over the roof. Clean eavestroughs in spring and fall to prevent water pooling near the foundation. Consider moving garbage bins away from exterior walls.
