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 Mice Removal Process in Markham
Inspection
The technician walks the entire foundation perimeter, checks every utility penetration (gas, water, electrical, cable), inspects the garage door seal, and examines where brick meets window and door frames. Inside, they check behind the stove, under the kitchen sink, and around basement utility stacks.
Treatment
Every gap 6mm or larger gets sealed. Steel wool packed into pipe gaps, metal flashing over larger holes, concrete patching for foundation cracks. The goal is to cut off entry before trapping begins — otherwise you are just catching new mice forever. Snap traps and tamper-resistant bait stations go along runways along walls and baseboards.
Prevention
Follow-up visits 2–4 weeks later confirm the population is eliminated. Any new activity triggers additional trapping and a re-inspection of the exclusion work. Most companies include 2–3 follow-up visits in the initial price. Exterior bait stations can remain as ongoing prevention.
Signs You Need Mice Removal in Markham
-
Rice-shaped droppings (3–6mm) along baseboards, in kitchen drawers, or under the sink — fresh droppings are dark and soft
-
Scratching or scurrying sounds in walls and ceilings between midnight and 4 AM
-
Gnaw marks on food packaging, electrical wires, or the corners of wooden baseboards
-
Grease marks along walls where mice run the same path night after night
-
Shredded paper, insulation, or fabric tucked into a hidden corner — nesting material
Why Hire a Professional in Markham
-
Mice can fit through a 6mm gap. A professional knows every common entry point on GTA housing types — semis, detached, towns, condos — and seals them all in one visit.
-
Poison bait inside living areas is dangerous for kids and pets, and a mouse that dies inside a wall cavity smells for weeks. Professionals use exterior bait stations and interior snap traps.
-
Trapping without sealing entry points is pointless. New mice move in from outside within days. Exclusion first, trapping second.
-
Most professional mouse jobs include 2–3 follow-up visits over 4–6 weeks. If activity continues, they come back at no extra charge.
-
Rats require different trap sizes, different bait, and heavier exclusion materials than mice. A pro correctly identifies whether you have mice or rats before choosing a treatment.
