Typical Cost in Markham
$150–$900
Final cost depends on severity, property size, and treatment method.
Markham's eclectic housing stock creates varied pest landscapes. Carpenter ants target moisture-damaged wood in Unionville heritage homes near the Rouge River. Pavement ants colonize foundations in Cornell and Box Grove new builds. Centipedes thrive in damp basements across Berczy and Cathedraltown. Spiders congregate in garages and garden sheds throughout Angus Glen. Licensed professionals in Markham delivers targeted pest management for every housing type.
Our General Pest Control Process in Markham
Pest Identification
Correct ID is the whole game. Carpenter ants require bait and nest location. Pavement ants need perimeter spray. Centipedes need moisture control. The technician identifies exactly what you have and where it is coming from before reaching for any product.
Targeted Treatment
Treatment goes where the pest lives, not everywhere. Ant bait at trail entry points. Residual spray along baseboards for crawling insects. Dust in wall voids and weep holes for hidden harborage. Targeted application uses less product and works better than broadcast spraying.
Entry Point & Condition Fixes
Gaps around doors, windows, pipes, and foundation cracks get sealed. Moisture issues that attract centipedes and silverfish get flagged. The technician cannot fix your plumbing, but they will tell you exactly where the moisture source is.
Follow-Up & Seasonal Prevention
A check-in 2–4 weeks later confirms the treatment worked. For homes with recurring issues — older homes with damp basements, houses near ravines — a quarterly treatment program keeps things controlled year-round.
Signs You Need General Pest Control in Markham
-
A line of small ants trailing across the kitchen counter or along a baseboard — follow the trail to find where they are entering
-
Large black ants (10–15mm) appearing inside during spring — these are carpenter ants, and their nest is in your walls
-
Sawdust-like frass piling up below a window frame, baseboard, or door casing — carpenter ant excavation debris
-
Centipedes or silverfish in the basement, bathroom, or laundry room — both are moisture indicators
-
Spiders concentrated in one area of the house — they build webs where other insects are present, so spiders mean a food source exists
Why Hire a Professional in Markham
-
Carpenter ants cause structural damage over time. A pro locates the actual nest — often inside a wall void near a moisture source — and eliminates the colony, not just the ants you see on the counter.
-
Over-the-counter ant sprays kill the ants on contact but never reach the colony. Professional baits are carried back to the nest and shared with the queen. That is how you eliminate the source.
-
Centipedes are a symptom, not the disease. A technician identifies the moisture source and the prey insects sustaining them, then addresses both.
-
Licensed technicians use products that are not available at retail — professional-grade residual sprays and baits with longer-lasting active ingredients and better targeting.
-
A quarterly prevention program costs less per year than dealing with one major infestation. It is the right move for older GTA homes that see the same pests every season.
