Pest Control in Toronto
Sterex is a licensed pest control and exterminator company serving Toronto. From cockroach infestations in condo kitchens to mice in semi-detached homes, our licensed technicians know the seasonal patterns and building types that drive pest pressure in the city.
What matters in Toronto
Toronto has a large share of apartments, condos, semis, and row houses. In multi-unit properties, the key inspection question is whether activity is confined to one unit or can move through shared walls, plumbing chases, and hallways, because that affects whether coordinated service is needed.
Toronto's housing runs from pre-war semis and rooming houses through post-war walk-ups to new condo towers. In older low-rise buildings, inspections should include damp framing, soffits, roof edges, and rodent entry gaps. In towers and walk-ups, shared kitchen, plumbing, and furniture pathways matter for cockroach and bed bug assessment.
Toronto housing mix
23.3%
of 1,160,895 occupied private dwellings are single-detached
Only 23.3% of Toronto's occupied private dwellings are single-detached — the lowest share of any city Sterex covers. The remaining mix includes apartments, condos, semis, and row houses, where bed bugs and German cockroaches can move between units through shared structure.

Common pests in Toronto
What we treat here
Toronto sees high cockroach pressure in condo towers and older apartments — German cockroaches in kitchens near appliances and plumbing chases. Mice move indoors in fall and early winter in semi-detached and detached homes. Bed bugs spread through multi-unit buildings, used furniture, and travel. Ants (carpenter and pavement) peak in late spring and summer. Raccoons are active in early spring and fall near ravines and mature tree canopies.

When each problem shows up in Toronto
Spring (March-May)
Raccoon and squirrel entry into attics and soffits during denning season, and the first carpenter ant swarmers appearing indoors — which usually means a nest is already inside, not outside.
Summer (June-August)
Wasp and hornet nests on balconies, soffits, and rear stairwells. Pavement ants along walkways and porches. Cockroach activity rises with kitchen heat and humidity in unairconditioned units.
Fall (September-November)
Mice move indoors as temperatures drop. Fall is an important time to inspect and seal entry points in low-rise housing instead of relying on baiting alone.
Winter (December-February)
Bed bug and cockroach work continues year-round because it is driven by heated interiors, not weather. Rodent activity stays high anywhere entry points were not sealed in the fall.
Local rules and programs
What applies specifically in Toronto
RentSafeTO sets the bar for apartment buildings
Toronto requires apartment building owners to keep units pest-free, inspect common areas at least every 30 days, inspect within 72 hours of being told about pests, use licensed operators where required, and post pest control records and schedules on the tenant notification board. Units with an active pest problem cannot be rented to new tenants. If you manage a building here, the documentation matters as much as the treatment.
City of Toronto — RentSafeTO building owner requirementsTermites have been established here since 1938
The City of Toronto records that the eastern subterranean termite was introduced to Toronto in 1938 and has since become established in homes throughout the city. Because these termites nest in soil rather than in the wood they feed on, treatment is a soil-and-structure job, not a spot treatment — and unlike carpenter ants, they attack only dead wood.
City of Toronto — Threats to trees: insectsCommercial work in Toronto
Toronto has the densest restaurant, retail, and managed-residential concentration in the GTA. Buildings under RentSafeTO need documented pest management, and food premises need records that survive a health inspection. Sterex issues a timestamped GorillaDesk PDF after every visit, which is the paper trail property managers and operators are usually asked to produce.
Commercial pest controlWildlife pressure in Toronto
Toronto's ravine system and mature street canopy put raccoons and squirrels against rooflines across the older parts of the city. Entry is usually at a soffit corner, a roof vent, or the gap where an addition meets the original roofline. Removal without sealing those openings tends to be temporary.
