Typical Cost in Markham

Final cost depends on severity, property size, and treatment method.
Markham has two pest realities separated by about 30 years of construction. Walk down Main Street Unionville and the heritage homes there have fieldstone foundations with gaps that mice have been using since before the town had a traffic light. Drive 15 minutes north to Cornell or Box Grove and the brand-new detached homes are already getting mice through settling gaps around gas lines and dryer vents — the foundation shifts in the first two winters and opens up entry points the builder never sealed. The Rouge River cuts through eastern Markham and delivers raccoons, skunks, and squirrels right into the backyards along Rouge River Estates. Milliken is rat territory — the dense mix of restaurants and food businesses along Steeles and McCowan feeds Norway rat populations that burrow under adjacent residential foundations. Angus Glen looks pristine, but the golf course is raccoon habitat and they do not stay on the fairways.
Our Bed Bug Treatment Process in Markham
Inspection
The technician checks mattress seams, box springs, headboard joints, baseboards, and electrical outlets. Bed bugs leave dark fecal spots, shed skins, and eggs in their hiding spots. Severity determines whether heat or chemical treatment is the right call.
Treatment
Heat treatment for a one-bedroom unit takes 6–8 hours and kills everything in one shot at 50 degrees. Chemical treatment targets every crack, crevice, baseboard gap, and furniture joint with professional residual products over 2–3 visits. For severe multi-unit infestations, a combination of both gets the best results.
Prevention
Two weeks after treatment, the technician returns to inspect. Interceptor traps go under bed legs to catch any survivors. If even one bug is found, retreatment happens immediately at no extra charge. Mattress encasements and interceptor traps are recommended going forward.
Signs You Need Bed Bug Treatment in Markham
-
Itchy red welts in a line or cluster on arms, shoulders, or neck that appear overnight
-
Tiny rust-coloured smears on your pillowcase or fitted sheet — blood from crushed bugs
-
Small black dots along mattress seams and in the piping — bed bug fecal spots
-
Translucent shed skins tucked into mattress folds and box spring corners
-
A sweet, stale smell in the bedroom — heavy infestations have a distinct musty odour
Why Hire a Professional in Markham
-
Drugstore sprays are repellents, not killers. They scatter bed bugs into walls and adjacent rooms, making the problem worse and harder to treat.
-
Heat treatment at 50 degrees kills every life stage — adults, nymphs, and eggs — in a single visit. No consumer product can do that.
-
Bed bugs hide in places most people never check: inside electrical outlets, behind baseboards, in curtain hems, inside clock radios.
-
In multi-unit buildings, treating one unit without inspecting adjacent ones is a waste of money. Professionals coordinate building-wide strategies.
-
Licensed technicians use products registered with Health Canada that have residual action for weeks. Over-the-counter products have no residual effect.
