ZeroBiteProfessional Termite Treatment in Toronto
While many Toronto homeowners believe termites are only a concern in southern climates, eastern subterranean termites are well established across parts of the GTA. Etobicoke has documented termite activity for decades, with colonies thriving in the sandy, well-drained soils common in the area's post-war neighbourhoods. Parts of Scarborough, particularly areas near the Bluffs and Rouge Valley, have also reported significant termite presence. As climate patterns shift and winters become milder, the termite-active zone in the Toronto area continues to expand, putting more homes at risk than ever before.
ZeroBite Pest Control provides comprehensive termite inspection, treatment, and monitoring for Toronto homeowners. Our licensed technicians use professional-grade moisture meters, borescopes, and thermal imaging to detect termite activity that is invisible to the naked eye. When treatment is needed, we use Termidor liquid barrier treatment, the gold standard in subterranean termite control, to create a continuous chemical barrier around your home's perimeter that termites cannot detect or avoid.
Termite Risk Zones in Toronto
Not all Toronto neighbourhoods face equal termite risk. Etobicoke is the most well-documented termite zone in the GTA, with active colonies confirmed in Alderwood, Long Branch, New Toronto, and Mimico. The sandy, glacial-deposit soils in these areas provide excellent conditions for subterranean termite colonies, which require moisture and direct soil contact with wood to survive. Homes built in the 1940s through 1960s with poured concrete or block foundations and wood-framed construction are most vulnerable.
In Scarborough, termite activity has been documented near the Scarborough Bluffs and in older residential areas of West Hill and Birch Cliff. Parts of North York and even some areas of old Toronto proper have had confirmed sightings in recent years. Homes with wood-to-soil contact, poor drainage around foundations, or untreated lumber in crawl spaces are at elevated risk regardless of neighbourhood. ZeroBite recommends annual termite inspections for all homes in documented risk zones and for any Toronto home older than 40 years.
Liquid Barrier Treatment
ZeroBite's primary termite treatment uses Termidor, a non-repellent liquid termiticide applied to the soil around and beneath your home's foundation. Unlike older repellent products that termites could detect and navigate around, Termidor is undetectable to termites. As they forage through treated soil, they pick up the active ingredient and transfer it to nestmates through grooming and contact, gradually eliminating the entire colony. Treatment involves trenching around the exterior foundation, drilling through concrete slabs where necessary, and injecting the product directly into the soil at the foundation interface.
For Toronto homes with finished basements, which is the vast majority of properties in Etobicoke and Scarborough, we minimize interior disruption by drilling small access holes through the basement slab at the perimeter, injecting treatment, and patching the holes. The entire process is typically completed in a single day, and there is no need to vacate your home. Termidor provides continuous protection for five to ten years, creating a zone of treated soil that eliminates termites before they can reach your home's structural wood.
Bait Monitoring Systems
For homeowners who prefer a less invasive approach or as a complement to liquid treatment, ZeroBite installs in-ground bait monitoring stations around your Toronto property's perimeter. These stations contain wood monitoring cartridges that termites discover during their natural foraging. When our technicians detect termite activity in a station during routine checks, we replace the monitor with a bait cartridge containing a slow-acting insect growth regulator. Foraging termites carry the bait back to the colony, where it disrupts moulting and gradually eliminates the colony over several months.
Toronto Termite Fact
The City of Toronto's building department has documented subterranean termite activity in Etobicoke since at least the 1950s. The Canadian Food Inspection Agency has confirmed expanding termite distribution in the GTA as winter temperatures trend warmer. Annual inspections are the best defence for Toronto homeowners in at-risk areas.

Termite Inspections for Toronto Real Estate
If you are buying or selling a home in a known termite zone in Toronto, a professional termite inspection is essential. ZeroBite provides detailed termite inspection reports that satisfy real estate due diligence requirements. Our inspections cover the full structure including basement, crawl space, exterior foundation, and accessible structural wood. We provide clear documentation of any findings and, when needed, treatment recommendations with firm pricing that can be included in purchase negotiations.
What to Expect During Treatment
Termite treatment begins with a thorough free inspection of your Toronto property. If termite activity or damage is confirmed, we provide a detailed treatment proposal. On treatment day, our crew trenches the soil around the exterior foundation, drills access points where needed, and applies the liquid barrier. The process typically takes four to eight hours for a standard Toronto home. You do not need to leave during treatment. Following treatment, we install monitoring stations and schedule annual inspections to ensure continued protection.
