Subterranean termites are the most destructive pest in GTA homes, causing more property damage per year than fire and floods combined in Canada. In the GTA, where older housing stock and clay soil create ideal termite conditions, the risk is real and ongoing. The City of Toronto and surrounding municipalities have documented termite activity in all major neighbourhoods.
Termites eat wood from the inside out, leaving only a thin outer shell. By the time homeowners notice damage — warped floors, buckling paint, or hollow-sounding wood — the colony has been active for months or years. The characteristic sign of subterranean termites is mud tubes: thin tunnels of soil and saliva that termites build along foundation walls to maintain moisture while travelling between their colony in the soil and the wood they feed on.
DIY termite sprays treat the surface, not the colony. Termites live in the soil. Only professional liquid termiticides applied to the soil create a continuous chemical barrier that eliminates the colony and prevents reinfestation. Annual monitoring inspections catch new termite activity before it causes significant damage.
How It Works
What to expect when you work with licensed termite treatment professionals.
Inspection
The technician inspects the foundation, basement, crawl spaces, and any wood-to-ground contact for signs of termite activity: mud tubes, wood damage, and live termites. Subterranean termites build mud tubes along foundation walls to maintain moisture while travelling between their colony in the soil and the wood they feed on.
Treatment
If active termites are found, a treatment plan is developed based on the extent of the infestation and the construction type. Options include soil treatment with liquid termiticide applied around the foundation perimeter, or wood injection treatment for localized infestations. Liquid termiticide creates a continuous chemical barrier in the soil.
Prevention
Annual monitoring inspections are the most important part of long-term protection. Most professional treatments include a multi-year warranty with annual inspections that catch new activity before it causes significant damage. Liquid termiticide barriers typically last 5–10 years.
Signs You May Need Termite Treatment
-
Mud tubes built along foundation walls, basement floors, or support piers — 6–12mm wide trails of dried mud
-
Wood that sounds hollow when tapped — termites eat wood from the inside out, leaving only a thin outer shell
-
Small piles of termite droppings (frass) near baseboards, windowsills, or basement walls — looks like fine sawdust or coffee grounds
-
Wooden structures that warp, buckle, or show damage without any obvious water leak
-
Swarmers (winged termites) emerging from wall voids or around the foundation in spring — often mistaken for flying ants
-
Paint that bubbles, peels, or shows water damage that does not match any known leak
Why Hire a Professional
-
Termites cause more property damage in Canada than fires and floods combined. In the GTA, where older housing stock and clay soil create ideal termite conditions, the risk is real and ongoing.
-
DIY termite sprays treat the surface, not the colony. Termites live in the soil. Only professional liquid termiticides applied to the soil create a barrier that eliminates the colony and prevents reinfestation.
-
Correctly identifying termites versus flying ants is essential — the treatments are completely different. A professional inspection eliminates the guesswork.
-
Termite warranties require annual monitoring. Most professional treatments include a multi-year warranty with annual inspections.
-
Subterranean termites require soil moisture to survive, which is why they enter homes through foundation cracks and wood-to-ground contact points.
