Annex demands something specific from a pest control operator — familiarity with pre-Confederation building structures, experience coordinating treatment across subdivided multi-tenant properties, and the kind of diagnostic depth that distinguishes a specialist from a generalist. Here is why Annex residents and property managers have chosen GTA Toronto Pest Control for over 20 years:
The unique character of The Annex, with its heritage homes and vibrant student population, also creates specific challenges when it comes to pest control.
The main challenge for pest control in Annex’s subdivided heritage homes is that they function as single, connected structures, even with separate tenancies. An infestation in one unit can quickly spread throughout the entire building via internal wall systems and shared plumbing before tenants are even aware of the widespread issue.
Our approach to pest control in Annex focuses on treating the entire building, not just individual units.
Not all Annex properties are rooming houses. Many have been restored to single-family homes, and these older buildings have unique vulnerabilities. Our services of pest control in Annex addresses the specific risks associated with 140-year-old heritage properties.
We bring the same licensed, guaranteed pest control standards to all neighbourhoods in Toronto and the greater GTA. Our service areas also include:

In most cases the answer is structural — the entry points and internal migration pathways that allowed the first infestation were never properly sealed after treatment. In 140-year-old subdivided buildings, these pathways are extensive and not always obvious. Our pest control in Annex residential areas includes permanent exclusion work alongside treatment — sealing confirmed and probable entry points with materials appropriate for heritage masonry structures so that recurrence requires a genuinely new introduction rather than just a re-population of the existing access routes.
Yes — and it happens regularly. The original plaster and lath wall construction in these buildings contains large void spaces that connect floors through gaps around pipework, original timber stud bays, and the openings created by decades of renovation. Treating only the floor or unit where bites were first reported without inspecting above and below almost always produces a temporary rather than permanent result.
Yes. These species require specific treatment approaches — targeting the harborage zones in aged structural materials rather than applying broad surface treatments. We carry products specifically formulated for these species and apply them in the moisture-retaining void spaces and dark undisturbed areas of heritage basements and attics where these insects concentrate.
Under Ontario’s Residential Tenancies Act, landlords are responsible for maintaining rental units in a state fit for habitation, which includes addressing pest infestations. We work regularly with Annex landlords and property managers — providing coordinated multi-unit treatment and full written service documentation that satisfies these legal obligations and protects landlords from tenant complaints and tribunal proceedings.

We are a Toronto-based Pest Control Company focused on delivering top-notch services since 1998.
