Licensed home exterminators for bats in the attic, soffits, and roofline. Free bat inspection. Same-day appointments across the Greater Toronto Area.
GTA Pest Solutions provides humane bat removal in Toronto and across the Greater Toronto Area. Our process starts with a professional inspection to identify bat entry points, determine whether a roost is active, and assess the condition of the attic or roofline.
When exclusion is appropriate, we use one-way bat doors and seal accessible entry points so bats can leave without being trapped inside. Because bats and their maternity roosts are protected in Ontario, exclusion work must be planned around the applicable seasonal restrictions and the species involved.
Our bat removal service covers Toronto, Mississauga, Brampton, Vaughan, Markham, Scarborough, North York, and Etobicoke.
Two bat species commonly associated with buildings in Ontario include the Big Brown Bat and Little Brown Myotis. Correct identification matters because species can have different conservation and protection considerations.
If you are unsure which bat is entering your attic or roofline, a technician can inspect the entry point and determine the appropriate exclusion approach.
| Comparison | Big Brown Bat | Little Brown Bat (Myotis lucifugus) |
|---|---|---|
| Build | Approximately 11–13 cm long; a bulkier species and the one most frequently encountered in GTA buildings. | Approximately 6–9 cm long with a 22–27 cm wingspan; noticeably smaller and lighter. |
| Legal Status | No special protection; the species most commonly removed from buildings. | Listed as Endangered under Ontario’s Endangered Species Act following severe declines caused by White-nose Syndrome. |
| Typical Roost | Chimneys, shutters, and small attic openings, usually in relatively small numbers. | Larger maternity colonies in attics and roof voids, sometimes with dozens of bats. |
| Habit | Typically emerges about 20 minutes after sunset to feed on flying insects. | Highly loyal to its roost, often returning to the same entry point year after year unless it is professionally sealed. |

Bats are quiet by day and active at dusk, so most homeowners smell or hear a problem before they ever see a bat. Watch for:
Hearing activity at dusk? Don’t try to seal the gap yourself; book an inspection instead.
Bats can create both health and property concerns when they enter an occupied building. A bat bite or scratch may be small or unnoticed, so suspected contact should be taken seriously and discussed with a healthcare provider or public health authority. The City of Toronto also advises avoiding direct contact with bats.
Accumulated bat guano can also contaminate attic spaces and create odour and sanitation problems. Professional inspection and appropriate cleanup can help reduce these risks.
Effective bat control Toronto homeowners can rely on is a system built around a narrow legal calendar, not a single visit. Every job follows the same Integrated Pest Management (IPM) sequence used by licensed operators across Ontario:
We check the roofline, soffits, fascia, chimney, and attic interior for active entry points, droppings, and colony size.
We determine whether exclusion can be carried out safely and lawfully based on the bat species, whether young are present, and the applicable Ontario wildlife protections. Exclusion is planned to avoid trapping flightless young inside an active maternity roost.
We install one-way bat valves at every active entry point. Bats can leave to feed but cannot re-enter, and no poisons or lethal traps are used.
Once the roost is confirmed empty, we permanently repair and seal soffits, fascia, chimney caps, and roof vents with durable, chew-resistant materials.
Contaminated insulation and droppings are removed and the space sanitized; full attic restoration is available where damage is extensive.
We follow up to confirm the exclusion holds, and every completed job is backed by a written guarantee.
This is why our results last where a trap-and-spray visit doesn’t. We work around the bats’ biology and Ontario’s legal calendar, not against them.

Bat activity across the Greater Toronto Area follows the region’s housing stock and green corridors:
Across Toronto, Scarborough, and Etobicoke, century and post-war homes often have wood soffits, loose fascia boards, and aging chimney caps that are easier for bats to squeeze through than newer aluminium-clad builds.
Properties near the Don Valley and similar green corridors sit close to insect-rich foraging grounds, which can draw bat colonies toward nearby rooflines and potential entry points.
In downtown high-rises and buildings with shared roof structures, one bat entry point behind a parapet or vent can become a building-wide problem if it is not sealed at the right time of year.
Older commercial and institutional buildings can contain large, undisturbed attic or belfry spaces that are suitable little brown bat maternity colony sites across the GTA.
During the summer maternity season, colonies gather to raise flightless pups through June, July, and into August. This can make activity around established entry points especially noticeable.
Do not seal an active bat entry point without first confirming whether bats are inside and whether young are present. Incorrectly timed exclusion can trap bats inside a wall or attic space.
A professional inspection helps identify active entry points, determine the appropriate exclusion approach, and identify areas that need permanent sealing or sanitation.
We provide bat exclusion for residential and commercial properties across the GTA.
For homes, our service focuses on identifying attic and roofline entry points, humane exclusion, permanent sealing, and cleanup where required.
For commercial buildings, condos, warehouses, and managed properties, we can assess multiple entry points and develop a documented exclusion plan based on the building’s structure and bat activity.

Bats are active at dusk, and you’ll usually hear a high-pitched squeak or fluttering rather than the running and scratching typical of squirrels or raccoons. An ammonia-like odour near the roost is another strong clue. If you’re unsure, send us a photo or a short recording before booking.
Cost depends on colony size, the number of entry points, and whether guano cleanup or attic restoration is needed. We quote a firm price after a free inspection, not over the phone.
Yes. We use one-way doors that let the colony leave to feed but never re-enter, and every job is timed outside the maternity season, so pups are never trapped inside.
Exclusion generally happens from mid-August through October, once the summer’s pups can fly and before bats settle in for winter hibernation. Work outside this window risks harming young bats and is not permitted.
Yes. Bats are protected wildlife in Ontario, and the little brown bat carries additional protection as an endangered species. We use humane exclusion and timed sealing instead of lethal methods.
Not if the entry point is sealed correctly. Bats are loyal to a roost site and will keep trying to get back in through any gap that’s left open, which is why permanent sealing is part of every job.
They can be. Disturbed guano dust has been linked to a rare lung infection called histoplasmosis, so we treat cleanup as a health step, not just a cosmetic one. See a doctor if you develop symptoms after exposure.
Confine it to the room if it’s safe to do so, keep people and pets away, and contact us or your local public health unit, especially if there’s any chance of a bite or scratch. Do not try to catch it barehanded.
Yes. Our commercial programs include scheduled roofline inspections, mapped exclusion work timed to the legal window, and written reports for building-wide compliance.
Yes. Bats can use small openings around soffits, fascia, rooflines, chimneys, vents, and other exterior features to access attic or roof spaces. A professional inspection can identify the active entry point and determine whether exclusion and sealing are appropriate.
The time required depends on the number of entry points, the location of the roost, the bat species, and whether cleanup or repairs are required. The first step is an inspection to determine the scope of work and the appropriate exclusion method.
We are a trusted pest control service provider offering safe, effective, and solutions homes and businesses.
