Bats enter GTA homes through gaps in rooflines, soffits, and chimney chases, and roost in attics and wall voids. Big brown bats and little brown bats are the two species found in GTA homes — they are not aggressive and will not attack unless handled. The health concern is histoplasmosis from bat guano, not the bats themselves.
Ontario law protects all bat species in the province. Trapping and relocating bats is illegal without a wildlife license. Sealing a building while bats are inside is also illegal — it traps them to die in the structure, creating a severe odour and contamination problem. The legal and effective method is one-way exclusion doors: the bat exits to forage at night and cannot return.
Bat exclusion timing matters critically. In May, June, and July, most female bats are in maternity colonies with flightless pups. Installing exclusion doors while pups are inside traps them to die in the attic. A professional schedules exclusion for when the pups are flying — typically late July or August in the GTA.
How It Works
What to expect when you work with licensed bat removal professionals.
Inspection
The technician locates bat entry points by inspecting the roofline, soffits, roof vents, and chimney chases during daylight when bats are out foraging. Guano accumulation and staining below entry points identifies active roosting sites.
Treatment
One-way exclusion doors are installed over active entry points. The bat exits to forage at night but cannot return. Exclusion timing is planned around the maternity season — late July or August in the GTA when pups are flying.
Prevention
Once bats are confirmed out, all entry points are sealed with steel mesh and caulking. Guano accumulation in the attic or wall void is cleaned and decontaminated. Bat guano contains histoplasmosis spores — cleanup requires proper PPE and commercial-grade disinfectant.
Signs You May Need Bat Removal
-
Bats flying out of the roofline, soffit, or chimney at dusk — most visible between July and September
-
Guano accumulation below roofline gaps, on the ground below roof vents, or in gutters
-
A strong ammonia smell in the attic during warm months — bat guano generates heat as it decomposes
-
Squeaking or chittering sounds from the attic at dusk when bats are becoming active
-
Bat entry points visible as small gaps in soffit junctions or roof vent perimeters
-
Guano staining on the exterior wall below roofline entry points
Why Hire a Professional
-
Ontario law protects all bat species. Trapping and relocating bats is illegal. One-way exclusion doors are the legal standard — a licensed professional knows the rules.
-
Bat guano contains histoplasmosis spores. Cleaning an attic contaminated with bat guano requires respirators, disposable suits, and commercial-grade disinfectants.
-
Bats enter through gaps as small as 15mm. Finding every entry point requires a professional roofline inspection.
-
Bat exclusion timing matters. Installing doors while maternity colonies are present traps flightless pups inside. A professional schedules exclusion for when pups are flying.
-
Guano continues generating histoplasmosis risk and ammonia odour even after the bats are gone. Professional decontamination is required.
