As the chill of winter settles over Scarborough, many homeowners focus on cozying up their interiors—but few realize they’re not the only ones looking for warmth. Raccoons, squirrels, skunks, and mice are all on the move, searching for safe, sheltered spaces to escape the cold. Unfortunately, your attic, garage, or basement may be the perfect winter hideout.
Wildlife intrusions spike in late fall and early winter across Ontario, and Scarborough homes—especially older ones—are highly vulnerable to these silent invaders. A single gap in the siding or an uncapped chimney can become an open invitation for nesting and destruction.
Seal Entry Points Around Your Home
Wildlife may seem clever, but they almost always use predictable access points to enter homes—and most of those are surprisingly small. In Scarborough’s colder months, raccoons, squirrels, and rats actively search for tiny cracks, gaps, and structural weaknesses to squeeze through and nest inside warm attics, basements, or crawlspaces.
Start your inspection by checking these common trouble spots:
- Rooflines & Soffits – Look for loose shingles, warped panels, or damaged fascia boards.
- Attic Vents & Eaves – Ensure screens are intact and tightly fastened with no signs of chewing or bending.
- Basement Windows & Foundation Cracks – Seal even the smallest gaps with caulking or expanding foam.
- Garage Doors & Utility Openings – Install rubber weather-stripping and cover pipe holes with steel mesh.
Pro Tip: Wildlife, like raccoons, can tear through wood or plastic. To prevent this for long periods, reinforce vulnerable spots with galvanized steel mesh or metal flashing.
Secure Outdoor Trash and Compost Bins
To wildlife, your trash is a treasure trove—especially in winter when natural food sources are scarce. Raccoons, skunks, and even rats are notorious for rummaging through unsecured bins, often making nightly visits that lead them closer and closer to your home.
If your garbage area isn’t well managed, it can become a long-term invitation for pests. Here’s how to tighten up your outdoor waste management:
- Use Wildlife-Proof Bins: Invest in bins with locking lids or snap-tight mechanisms to prevent animals from prying them open.
- Keep Bins Off the Ground: Elevate them on sturdy racks or platforms to reduce ground-level access.
- Store Indoors if Possible: Keep bins in a garage or enclosed shed, especially overnight.
- Neutralize Odours: Clean bins regularly with vinegar or baking soda and double-bag food scraps in colder months.
- Secure Compost Heaps: Use enclosed composters rather than open piles, and avoid adding meat, dairy, or greasy food.
Local Insight: In urban parts of Scarborough, raccoons have adapted to city life and can easily topple light plastic bins. Switching to heavier, lockable models can drastically reduce nighttime visits.
Trim Trees and Remove Overhanging Branches
If there’s a direct “bridge” from a tree to your roof, you might be handing squirrels and raccoons a first-class ticket into your attic. In many Scarborough neighbourhoods, mature trees and overgrown yards create the perfect access routes for agile climbers looking to nest before winter.
Here’s how to cut off their rooftop highway:
- Trim Back Branches: Keep tree limbs at least 6 to 8 feet away from your roof to prevent easy jumps.
- Remove Ivy and climbing Vines: These give rodents and wildlife a natural ladder to windows, vents, and gutters.
- Clear Roof Debris: Accumulated leaves or broken branches can hide chew damage or openings that wildlife exploit.
- Inspect Roofline After Storms: Wind damage can create gaps—wildlife often strikes when you’re unaware.
Fun Fact: Squirrels can leap over 10 feet horizontally. Even small overhangs can serve as launchpads—so don’t underestimate distance when pruning.
Inspect & Cap Chimneys and Exterior Vents
Chimneys and exterior vents are some of the most overlooked wildlife entry points, yet they’re often the easiest for animals to exploit. In Scarborough, raccoons, squirrels, birds, and even bats frequently enter homes through uncapped chimneys or uncovered vents, especially in late fall as they search for warm, hidden places to nest.
Here’s how to secure these access points:
- Install Chimney Caps: Use professionally fitted, stainless steel chimney caps with mesh screens that prevent nesting while allowing proper ventilation.
- Cover Dryer and Bathroom Vents: Add animal-proof vent guards that block wildlife but allow air to flow freely.
- Check Exhaust Outlets: Ensure kitchen and furnace exhausts are not cracked or loosely installed.
- Look for Nesting Material: Twigs, insulation, or droppings near your fireplace or vents could signal a current intrusion.
Warning Sign: If you hear rustling sounds in your chimney or see nesting material falling into the fireplace, don’t light a fire—wildlife may occupy it.

Why Wildlife Prevention Matters in Scarborough
Scarborough’s mix of suburban housing, mature trees, and nearby ravines creates the perfect habitat for raccoons, squirrels, and other nuisance wildlife. But when temperatures drop, these animals look for warmth—your home becomes their ideal shelter.
Here’s why prevention is critical:
Structural Damage
Raccoons can rip apart shingles and vents, squirrels can chew through wiring and wood, and rodents often burrow through insulation. These intrusions lead to costly repairs, and delaying professional raccoon removal in Scarborough can escalate the damage significantly.
Health Risks
Small pests can carry parasites, viruses, and bacteria. Droppings and urine from rodents or raccoons can spread disease and contaminate indoor air, so effective rat control in Scarborough is crucial for protecting your family’s health.
Fire Hazards
Chewed electrical wires (especially by squirrels or rats) are a serious fire risk. Most homeowners don’t discover the damage until something sparks. If you hear scampering in the walls or attic, searching for a service that provides squirrel removal near you can prevent a potential disaster.
Re-infestation
Once a raccoon or squirrel has nested inside, it often returns every season unless the entry point is properly sealed and deodorized.
Prevention Saves Money
Preventative action in the fall is far more affordable than emergency wildlife removal or home restoration in the middle of winter.
Conclusion
Winter in Scarborough brings icy winds and snowfall, as well as a surge of wildlife looking for shelter. By sealing entry points, securing trash, trimming branches, capping chimneys, and scheduling our professional inspection, you can safeguard your home from costly damage and unwanted stress.
