Ground squirrels and tree squirrels are a common wildlife pest problem across BC properties. They damage gardens, chew through wiring, nest in attics and crawl spaces, and burrow under foundations. Here’s what works for dealing with the squirrel problem on your BC property.
Identifying Your Squirrel Problem
BC properties deal with two main squirrel types. Tree squirrels (including the grey squirrel and red squirrel) nest in trees and access buildings through gaps in the roofline, soffits, and fascia boards. They store food in attic insulation, chew through wiring, and cause significant damage before they’re noticed. Ground squirrels burrow under patios, foundations, and garden beds, destabilising surfaces and damaging plant roots.
Best Methods for Squirrel Control in BC
Exclusion first: The most effective long-term squirrel control method is preventing access. Inspect the roofline for gaps at soffits, fascia, and where roof sections meet. Install heavy-gauge wire mesh over vents and openings. Trim tree branches that overhang the roof by at least 3 metres — squirrels use these as access points.
One-way exclusion devices: For squirrels already inside the attic, one-way exclusion devices allow them to leave but prevent re-entry. This is the humane and most effective approach for established attic squirrels.
Live trapping: Live cage traps baited with peanut butter or sunflower seeds are effective for ground squirrels in the garden. Check traps twice daily and relocate captured squirrels at least 5km away.
Habitat modification: Remove bird feeders (a major squirrel food source), secure compost bins, and clear brush piles near the building. Reducing food availability is a key component of long-term squirrel management.
When to Call a Professional
If squirrels are inside your attic or walls, professional removal is the safest approach. Professionals have the equipment to locate all entry points, install exclusion devices correctly, and seal the building envelope after removal to prevent future entry.
