Squirrel Removal in Mississauga

Mississauga’s dense suburban canopy and conservation corridors provide the perfect launchpad for Eastern Grey Squirrels to access your roof. When a squirrel decides the attic of your Mississauga home is warmer and safer than a tree in Erindale Park, they don’t look for an open door. Because their teeth never stop growing, they simply chew their way in. They chew through plastic roof vents, gnaw on wood fascia boards, and push past aluminum soffit panels. Once inside, the real threat isn’t the noise — it’s the fire hazard. Squirrels chew on wooden trusses to file their teeth, but they also chew the plastic casing off electrical wiring. Chewed wires are a leading cause of undetermined attic fires in residential homes. Pestisect provides humane, permanent squirrel removal across Mississauga. We use specialized one-way doors, perform hands-on baby extraction during breeding seasons, and seal entry points with chew-proof 16-gauge steel mesh to guarantee they can’t return.

Where Mississauga Squirrels Break In

Mississauga features a massive mix of housing stock, from the older homes of Port Credit to the modern subdivisions of Churchill Meadows. Squirrels exploit specific weak points on every type of roof.

Plastic Roof Vents: Builder-grade plastic vents or thin aluminum vents are installed to let attic air out, not to keep wildlife out. A squirrel can chew through the plastic louvers or flimsy bug screen in minutes.

The “Soffit Push-Up:” Common in newer homes with complex rooflines. Where a lower roof intersects with a second-story wall, squirrels sit on the shingles, push their heads against the aluminum soffit panels above, pop the track, and slip into the attic void.

Roof Edges (Drip Edge): In older homes with deteriorating roof sheathing (common near the lake or river where moisture is higher), squirrels sit in the eavestrough and chew right through the wood decking at the roof’s edge.

Plumbing Mats: The rubber or lead gasket surrounding the plumbing stack pipe on your roof. Squirrels chew through the rubber and squeeze down alongside the pipe.

The "Double Baby Season" Factor

Squirrels have *two* distinct breeding seasons in Ontario: spring (March to May) and late summer (August to September).

If you hear squirrel activity during these months, you almost certainly have a nest of babies. Squirrel babies are hairless, blind, and immobile for several weeks.

If a pest control company simply puts a one-way door over the hole, the mother will be locked out, and the babies will die in your attic. The mother will also destroy your roof ripping up shingles and chewing through plywood in a frantic attempt to get back to her young.

Our humane approach to baby squirrels:
During baby season, we suit up, physically enter your attic, locate the nest (usually buried deep in the insulation near the eaves), and remove the babies by hand. We place them in a heated “reunion box” on the roof next to the one-way door. When the mother exits, she finds her babies and carries them one-by-one to a secondary den in a nearby tree.

Preventative Roof Vent Screening

Squirrels are highly territorial. When we lock a squirrel out of your attic, she will often run across your roof to the next plastic roof vent and try to chew her way in there. To prevent this “whack-a-mole” scenario, we highly recommend preventative screening. While we are on your roof, we can install heavy-gauge steel mesh covers over all your vulnerable roof vents, plumbing mats, and exhaust vents, completely squirrel-proofing your roofline.

Squirrel Removal

Our Humane Squirrel Removal Process

We follow Ontario’s strict wildlife regulations. We do not trap or poison. Our focus is on getting them out safely and keeping them out permanently.

Inspection

We conduct a full exterior roof inspection to locate the main entry point and assess vulnerability. We also inspect the attic for babies and chewed wiring.

One-Way Door

We install a small, specialized steel one-way door over the main hole. The squirrel pushes its way out to forage but cannot get back in.

Steel Reinforcement

We wrap the area around the door in 16-gauge PVC-coated galvanized steel mesh. Without this, a frustrated squirrel will just chew a new hole right next to the old one.

Removal & Sealing

After 3–5 days, we return, verify the squirrels are gone, remove the one-way door, and permanently seal the hole with steel mesh and roofing sealant.

Squirrel Patterns

Mississauga Neighbourhood Squirrel Patterns

Port Credit, Clarkson, Lakeview: Older homes surrounded by massive mature trees. Branches touching the roof act as highways for squirrels. Trimming branches at least 6 feet back from your roofline is critical. Moisture-softened wood near the lake is also easier for squirrels to chew.

Streetsville, Erindale, Meadowvale: Proximity to the Credit River corridor means constant wildlife pressure. Preventative roof vent screening is highly recommended for homes near the river or conservation lands.

Erin Mills, Churchill Meadows, Lisgar: Newer suburban homes. The primary entry point in these neighbourhoods is usually builder-grade plastic roof vents and loose aluminum soffits at roof intersections.

Frequently Asked Questions

Can I legally trap a squirrel in Mississauga and release it in a park?

No. Under Ontario’s Fish and Wildlife Conservation Act, it is illegal to trap and relocate wildlife more than 1 kilometre from where it was captured. Doing so spreads disease and usually results in the animal’s death, as they don’t know where to find food or shelter in the new territory. Our one-way door system is the legal, humane solution.

How much does squirrel removal cost in Mississauga?

Typical humane removal (inspection, one-way door installation, baby extraction if necessary, and final seal of the primary entry point) ranges from $300 to $450 depending on the height and steepness of the roof. Preventative screening of your other vulnerable roof vents is quoted separately.

Will Mississauga Animal Services remove the squirrel from my attic?

No. Mississauga Animal Services only responds to domestic animals or sick/injured wildlife found on public property. Removing wildlife from a private residence is the homeowner’s responsibility and requires a licensed private wildlife control company.

Does home insurance cover squirrel damage to my roof and wiring?

Standard Ontario home insurance policies typically exclude damage caused by “rodents and vermin.” Because squirrels are classified as rodents, the damage they cause to your roof, insulation, and electrical wiring is usually not covered. This makes prompt removal critical before they cause a fire hazard.

Can I just block the hole myself when the squirrel leaves for the day?

Never block a hole unless you are 100% certain all squirrels (including hidden babies) are out. If you trap a squirrel inside, it will panic and cause massive damage trying to escape, or it will die and cause a severe odour and fly infestation in your home. A professional one-way door guarantees they can leave safely.
