Mice Problems in Markham? Here's How We End Them.
From heritage homes in Unionville to dense townhouse blocks in Cornell and Berczy, Markham gives mice two very different ways in: aged foundations with settled gaps, and shared townhouse walls where one untreated unit re-seeds the whole row. Sani IQ's Markham technician is based in the area, knows both housing types, and treats the cause — entry points and travel routes — not just the symptoms.
Signs You Have Mice in Your Markham Home
- Droppings under the kitchen sink or along garage walls
- Scratching in shared townhouse walls at night
- Chewed pantry packaging or pet food bags
- Musky odour in closets, pantries, or utility rooms
- Recurring activity even after store-bought traps
Complete Mice Protection is $495 (two visits, with entry-point sealing on the second) including inspection, treatment and entry-point review. Year-round Mice Protection plans are $895/yr with quarterly visits and free re-treatments in between. You'll get an exact, no-surprise quote before any work starts.

Our Process
How Sani IQ Handles Mice in Markham
Full-home inspection
We inspect the exterior foundation, garage, utility lines, attic and kitchen kick-plates to map every entry point and nesting area — mice fit through a gap the width of a dime.
Treatment + secured baiting
Tamper-resistant, pet-safe bait stations and snap-trap placements at active runways, sized to the infestation — never a one-spray-fits-all.
Exclusion & sealing
We seal entry points with rodent-proof materials (steel wool, mesh, sealant) so the next generation can't move in. This is the step most companies skip.
Follow-up & guarantee
Activity is monitored and re-treated free within your guarantee window. Mice return? So do we.

Mice Control in Markham — FAQs
How much does mice control cost in Markham?＋
Complete Mice Protection in Markham is $495 — two visits, three weeks apart —, including inspection, treatment and entry-point review. The $895/yr Mice Protection plan adds quarterly visits and free re-treatments — the right call for townhomes where neighbouring units keep pressure on.
My townhouse keeps getting mice — why?＋
In Markham townhouse rows, mice travel between units through shared wall voids and pipe chases. Treating one unit without sealing it just invites the next wave. We treat your unit and seal your envelope, and can document findings for your property manager or neighbours.
Is your team local to Markham?＋
Yes — one of our senior technicians is based in Markham, which is why same-day windows are usually available across Markham, Unionville and Milliken.
Are the treatments pet-safe?＋
Yes. Locked, tamper-resistant stations and Health Canada–registered products only — we'll show you every placement before we leave.
