The most effective way to remove ants in the GTA is targeted baiting that eliminates the colony at the source, combined with sealing entry points — surface sprays only kill visible ants and rarely stop the colony from returning.
Carpenter ants and pavement ants are the two species we see most in GTA homes. Carpenter ants hollow out damp or damaged wood to nest — often in rotting fascia boards, deck posts, or leaky window frames — while pavement ants build small mounds along driveways, sidewalks, and foundation cracks and often push indoors through gaps in the slab.
Left alone, a carpenter ant colony can weaken structural wood over time, and any ant activity indoors signals an accessible food or moisture source nearby that’s worth finding regardless of species.
We trace the trail back to the colony rather than treating what’s visible, use targeted baiting to eliminate the nest at the source, and seal the entry points that let ants back in. Every visit starts with a full inspection and a clear explanation of what we find, backed by a satisfaction guarantee and 24/7 emergency response.

Carpenter ants work slowly compared to termites, but an untreated colony can weaken wood framing over several years, especially in already-damp areas like window sills and deck ledgers.
Not always — targeted baiting lets worker ants carry treatment back to the colony, so we don't have to physically locate every nest to eliminate it.
Often yes — ants foraging indoors are usually workers from an outdoor or wall-void colony following a scent trail to a food source.
