Final cost depends on severity, property size, and treatment method.
Scarborough has the widest range of pest problems in the GTA, and it comes down to the housing mix. The apartment towers along Lawrence and McCowan have chronic cockroach and bed bug issues — these buildings share plumbing risers, garbage chutes, and wall voids between units, and pests travel through all of them. Drive ten minutes east to Agincourt or Woburn and it is a different story: mice in the foundation walls of 1960s bungalows, raccoons ripping through aluminum soffits, carpenter ants in the older split-levels with water damage around the bathroom windows. Highland Creek runs through the middle of the district like a wildlife highway, and the Rouge Valley on the eastern edge brings everything from raccoons and skunks to coyotes right up to the backyards in Malvern and West Hill.
Our Ant Control Process in Scarborough
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.

Why Hire a Professional in Scarborough
-
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.
