A homeowner in North York heard scratching in the ceiling for three nights before she finally called someone. By the time we got there, a raccoon had been living in the attic for close to two weeks, and the entry point turned out to be a gap where a soffit panel had pulled away from the roofline. It wasn’t a new problem. It had been there for over a year. The raccoon just found it first.
This is how almost every wildlife intrusion starts. Homes don’t get invaded through the front door. They get entered through a small, overlooked gap that’s been sitting there long enough for something to notice.
Wildlife entry points Toronto homes have in common tend to fall into the same five categories, year after year. Knowing where to look is the difference between catching a gap before spring and finding a nest in your attic by summer.
Why Toronto Homes Are an Easy Target for Wildlife
Toronto’s mix of mature tree cover, older housing stock, and dense residential neighborhoods creates ideal conditions for raccoons, squirrels, skunks, and even the occasional opossum to move close to homes. Mature trees provide direct access to rooflines, and older homes often have wear points around the roof, foundation, and siding that newer builds don’t.
Add in a harsh winter every year, and wildlife has a strong reason to look for a warm, dry space to nest in. Attics and crawl spaces offer exactly that, provided there’s a way in.
Roof and Soffit Gaps
The roofline is the most common access point we find on service calls. Soffit panels, the material running along the underside of the roof edge, are often just nailed or clipped into place, and they weaken over time from weather exposure and age.
Raccoons are strong enough to pry a loose soffit panel open, and once there’s a gap, they’ll often widen it to fit through comfortably. Squirrels don’t even need much force. A gap of two inches is enough for a squirrel to squeeze through, and they’ll gnaw wood or vinyl trim to widen a smaller opening.
Roof vents, especially turbine and box vents, are another weak point. The mesh screening inside them corrodes or gets knocked loose, leaving a direct path into the attic.
Chimneys and Vents
An uncapped chimney is basically an open invitation. Raccoons use chimneys as den sites, particularly in spring when females are looking for a safe spot to raise young. Once inside the flue, they can drop into the fireplace or get stuck between the damper and the cap.
Dryer vents, bathroom exhaust vents, and gable vents all present the same risk if they don’t have proper screening. A vent flap that’s stuck open or missing its cover gives smaller animals, particularly squirrels and mice, a direct route inside.
Foundation and Crawl Space Openings
Skunks and groundhogs tend to target the base of the home rather than the roof. Gaps under decks, porches, and along foundation walls give them a low, sheltered spot to dig into.
Foundation vents that have lost their screening, cracks in the foundation itself, and gaps around where utility lines enter the home are all common access points at ground level. These are easy to miss because homeowners rarely walk the full perimeter of their foundation looking for damage.
Damaged Siding and Fascia Boards
Wood siding and fascia boards that have started to rot from moisture exposure are soft enough for raccoons and squirrels to tear through with minimal effort. Once an animal finds a weak spot, it usually doesn’t take long to turn a small crack into a hole big enough to climb through.
This is especially common on the shaded side of a house, where moisture sits longer and wood breaks down faster than the sun-exposed sides.
Decks, Sheds, and Porches
Gaps underneath decks and porches are prime real estate for skunks and groundhogs looking for a den site close to the house but out of direct view. These spaces are often left completely unscreened, since most homeowners don’t think of the underside of a deck as part of their home’s perimeter.
Sheds face a similar issue. A gap where the shed floor meets the ground, or a loose panel on the exterior wall, gives smaller animals shelter that’s rarely checked more than once or twice a year.
How to Check Your Home for Entry Points
A full check doesn’t require special tools, just a walk around the exterior with a clear view of the roofline, foundation, and any structure attached to the house. Look for:
- Soffit or fascia panels that look loose, warped, or pulled away from the roof
- Gaps around vents, chimneys, and where utility lines enter the home
- Cracks or holes at the foundation, particularly near corners
- Chew marks on wood trim, siding, or vent covers
- Openings under decks, sheds, and porches wide enough to fit a fist through
Spring and fall are the two best times to do this, since spring nesting season and fall’s search for winter shelter are when wildlife is actively looking for a way in.
If an animal is already inside, sealing these gaps before it’s removed traps it in the attic or wall void, which usually leads to more damage and, eventually, an odor problem that’s far harder to deal with. Our Wildlife Removal service handles the animal first, then seals every entry point so nothing gets back in behind it.
FAQ
What’s the most common way wildlife gets into Toronto homes?
Roof and soffit gaps are the most frequent entry point we see, particularly where soffit panels have loosened from age or weather damage. Chimneys and foundation gaps come in close behind, depending on the type of animal.
How big does a gap need to be for an animal to get in?
It depends on the species. A squirrel can fit through a gap around two inches wide, while a raccoon typically needs closer to four inches, though a determined raccoon will often widen a smaller opening rather than look elsewhere.
Can I seal entry points myself?
You can seal points where you’re certain nothing is currently inside, using materials like heavy-gauge mesh or metal flashing rather than wood or foam, which animals can chew through again. If you hear noise in the attic or walls, get it inspected before sealing anything, since trapping an animal inside creates a bigger problem.
How often should I check my home for wildlife entry points?
Twice a year is a reasonable baseline, ideally once in spring and once in fall, since these line up with when wildlife is most actively searching for shelter. Homes near mature trees or ravines may need more frequent checks.
Does wildlife control in Toronto include repairing the damage after removal?
Most professional services combine removal with exclusion work, which means sealing the entry point and repairing the immediate damage so the same spot doesn’t get used again. Larger structural repairs, like replacing damaged insulation, are sometimes handled separately depending on the extent of the damage.
Seal the Gaps Before Wildlife Finds Them
Every entry point on this list starts small and gets found eventually. The gap doesn’t need to be obvious to you. It just needs to be there long enough for a raccoon or squirrel testing the perimeter of your home to notice it.
If you’ve heard noise in your attic, spotted damage along the roofline, or just want a full exterior check before nesting season, our team at The BS Pest handles wildlife control Toronto homeowners trust for both removal and exclusion. Contact us for a free inspection.
