Ant Control in Toronto & GTA
Ant infestations in Toronto homes peak in summer when carpenter and pavement ants forage indoors. Professional ant control uses targeted bait to eliminate the colony, not just the workers you see.

Final cost depends on severity, property size, and treatment method.
Not all ants are the same. Carpenter ants tunnel through wood and can cause structural damage. Pavement ants nest under slabs and driveways. Odorous house ants colonize near moisture sources. The technician identifies the species from foragers, entry points, and nesting signs before any treatment begins. Over-the-counter ant sprays scatter workers and cause colonies to split, making the problem worse. Professional ant baits are carried back to the colony and shared with the queen — that is the only way to eliminate the source. Each gap around windows, doors, utility penetrations, and foundation cracks gets sealed, and moisture conditions that attract carpenter ants are flagged.
How It Works
What to expect when you work with licensed ant control professionals.
Inspection
The technician identifies the ant species from foragers, entry points, and nesting signs. Carpenter ants tunnel through wood. Pavement ants nest under slabs. Odorous house ants colonize near moisture. Correct ID determines every subsequent step.
Treatment
Professional ant baits are placed along foraging trails and carried back to the colony where they are shared with the queen. This eliminates the source. Surface sprays scatter workers and cause budding — the colony fragments into multiple colonies, making the problem significantly worse.
Prevention
Every gap around windows, doors, utility penetrations, and foundation cracks gets sealed. The technician flags moisture conditions and wood damage that attract carpenter ants, so you can address the root cause and prevent reinfestation.
Signs You May Need Ant Control
-
Lines of small ants trailing across kitchen counters and along baseboards
-
Large black carpenter ants (10–15mm) appearing indoors during May and June
-
Sawdust-like frass piling below window frames, baseboards, or door casings
-
Ant hills appearing in lawn edges, garden beds, or along driveway cracks
-
Live ants visible inside walls, behind baseboards, or near the hot water tank
-
A sweet musty smell near ant trails — aggregation pheromone from a nearby colony
Why Hire a Professional
-
Carpenter ants excavate wood to build nests. A colony inside a wall frame can cause thousands in structural damage before you notice. A pro locates the nest and eliminates it.
-
Over-the-counter sprays kill workers on contact but never reach the queen. Professional baits are carried back to the colony — the only way to eliminate it.
-
Different ant species require different baits and placement strategies. A pro identifies the species correctly before choosing a treatment.
-
Carpenter ants are drawn to moisture-damaged wood. A technician identifies the moisture source and recommends fixes.
-
Ant colonies split when disturbed — called budding. Spraying without baiting fragments the colony into multiple groups, making the problem far worse.
