Ajax Pest Control

Pest Control in Ajax

Sterex provides residential and commercial pest control across Ajax. Ajax's lakeside location and the Duffins and Carruthers Creek corridors create steady rodent, ant, and wildlife pressure across the town's neighbourhoods. Our licensed technicians serve homes, townhomes, condos, and businesses throughout Ajax and Durham Region.

What matters in Ajax

Ajax is almost two-thirds detached housing and largely built since the 1990s, so most pest work here is exterior-first — sealing rodent entry points at garages and grade rather than treating unit-to-unit spread.

Ajax is dominated by subdivision housing built from the 1990s onward, with older neighbourhoods near the lake and the Harwood corridor. Newer builds are not as sealed against rodents as owners expect: garage door seals wear at the corners and utility penetrations at grade are often left open. Pavement ants along interlock and driveways and wasp nests in fresh soffit and stone-veneer gaps are the other recurring calls.

64.7% of Ajax's 39,490 occupied private dwellings are single-detached, and much of that stock was built from the 1990s onward. Newer detached housing shifts the work toward garage and grade-level rodent entry rather than unit-to-unit spread.

Common pests in Ajax

What we treat here

Ajax's proximity to Lake Ontario and the Duffins and Carruthers Creek corridors drives rodent and wildlife pressure — mice move indoors in fall and winter, and raccoons and squirrels are active near the creeks and ravines. Ants (pavement and carpenter) peak in late spring and summer. Wasps are a summer issue. Bed bugs and cockroaches occur in rentals and multi-unit buildings across Central Ajax.

Local rules and programs

What applies specifically in Ajax

Durham Region's rodent guidance

Durham Region Public Health notes that a mouse can squeeze through a hole about the size of a dime, and that good sanitation comes first — keeping areas clear of food and debris, and clearing brush and rubbish from around buildings to remove hiding places. For a tenant dealing with bed bugs, the Region directs you to the landlord or building manager before a pest control professional.

Commercial work in Ajax

Ajax's commercial pest work runs to retail plazas, restaurants, and industrial and distribution sites near Highway 401 and Salem Road. Programs are built around dock doors, exterior bait station lines, and documented service records.

Commercial pest control

Wildlife pressure in Ajax

Duffins Creek, the Lake Ontario waterfront, and Ajax's maturing tree canopy bring raccoons and squirrels to rooflines. Roof vents and the junction where a garage roof meets the main wall are the usual entry points on this housing stock.

Frequently asked questions

Pest control questions for Ajax

Because newer construction is not sealed against rodents as thoroughly as most owners assume. Durham Region Public Health notes a mouse can pass through a hole about the size of a dime. In Ajax the recurring routes are worn garage door seals, the unsealed gap where utilities run from the garage into the house, and cable or hose-bib penetrations at grade. Mice treatment starts at $200 + HST for a townhome and includes sealing accessible gaps.

Yes. With 64.7% of Ajax dwellings single-detached, most nests turn up on exterior surfaces — soffits, stone-veneer gaps, shutters, decks, and sheds. An accessible exterior nest under 9 ft starts at $175 + HST, and above 9 ft usually starts at $250 + HST. A nest inside a soffit or wall void needs a custom quote, because the opening you can see is often not where the nest actually sits.
