Targeting the Source, Not Just the Symptoms

Common Pest Problems in Toronto
Cockroach Extermination
German cockroaches are the most common species found in Toronto's multi-unit residential buildings, restaurants, and older homes. They reproduce rapidly and move freely between units through shared plumbing chases, wall cavities, and electrical conduits — making an infestation a building-wide problem, not just a single-unit issue. Over-the-counter spray products are not effective against established cockroach populations; they scatter rather than eliminate. Our cockroach control program uses professional gel baiting, residual application, and crack-and-crevice treatment to eliminate the entire population, including harborage populations not visible on the surface.
Mice and Rodent Control
Mice and rats are a persistent problem in Toronto, particularly in older neighbourhoods and properties near ravines or construction sites. Toronto's aging housing stock — especially in areas like the Annex, East York, Leslieville, and Danforth — provides abundant entry points through foundation cracks, utility penetrations, and gaps around aging pipe runs. Rodents contaminate food, damage wiring, and create structural problems. Our mice control and rat control programs combine interior trapping, exterior bait stations, and complete structural exclusion to eliminate the infestation and prevent re-entry.
Ant Control
Pavement ants and carpenter ants are common across Toronto's residential neighbourhoods. Carpenter ants are particularly destructive in homes with mature trees or any history of moisture intrusion — both widespread in Toronto's older residential areas. They excavate wood for nesting galleries, causing structural damage that can go undetected for an entire season. Our carpenter ant control and ant control services locate the colony and apply targeted treatments that eliminate it at the source.
Wasp Nest Removal
Wasps nest in eaves, soffits, wall voids, and attic spaces on Toronto homes throughout the summer. A single nest can house thousands of highly aggressive insects by late August. Nests in wall voids are particularly dangerous — homeowners encounter them without warning. We provide safe, complete wasp nest removal for residential and commercial properties across Toronto, with same-day service available during peak season.
Wildlife Removal
Raccoons are Toronto's most well-known urban wildlife pest. They access attics, chimneys, and soffits, causing significant insulation and structural damage, and return year after year to the same entry points until they are permanently sealed. Squirrels also move into attics and wall cavities in large numbers. Our wildlife removal team provides humane one-way removal, baby animal assessment, and permanent heavy-gauge steel mesh exclusion at all entry points. See dedicated pages for raccoon removal and squirrel removal.

Seasonal Pest Control in Toronto
Spring (March–May)
Raccoon denning season peaks in March and April as females seek attic space for spring nesting. Toronto's ravine system sustains a large raccoon population — activity is city-wide. Carpenter ants re-activate in May, particularly in ravine-adjacent neighbourhoods with abundant dead wood. Wasp queens start new nests in late May under soffits, in eaves, and in wall voids of older residential buildings.
Summer (June–August)
Summer is peak season for cockroaches in Toronto's food service businesses, multi-unit buildings, and commercial corridors. Wasp nests grow rapidly and become dangerous by August. Carpenter ant and pavement ant activity peaks throughout the residential areas. Rat activity around Toronto's commercial food waste concentrates highest through the hottest months.
Fall (September–November)
Fall is the highest-risk season for Toronto homeowners. Mouse infiltration from ravine and park areas begins in September — properties directly adjacent to the Don Valley, Humber River, and other ravine corridors see the earliest and most intense entry attempts. October brings peak infiltration across the city. Raccoon movement increases significantly as animals prepare for winter denning.
Winter (December–February)
Cockroaches in Toronto's multi-unit buildings and commercial properties are completely unaffected by cold weather — they continue to spread through shared building infrastructure year-round. Mice established inside Toronto homes in fall remain active throughout winter. Raccoons in attics continue causing damage. Winter is an effective exclusion window for rodents, with concentrated indoor activity confirming treatment results.
