Mice Problems in Toronto? Here's How We End Them.
Toronto is one of Canada's busiest cities for mice — century homes in the East End with stone foundations, row houses with shared walls, restaurants on every corner, and constant construction that displaces rodents into the surrounding blocks. Whether it's a Leaside semi, a Scarborough bungalow or a downtown condo, Sani IQ treats the cause: we locate the entry points and nesting sites, eliminate the activity, and seal the building so it doesn't repeat.
Signs You Have Mice in Your Toronto Home
- Droppings in kitchen drawers, under sinks, or along baseboards
- Scratching in walls and ceilings after dark
- Chewed food packaging in pantries and cupboards
- Greasy rub marks along baseboards and pipe runs
- Neighbours renovating — displaced mice move next door
Mice already inside? The Sani IQ Rodent Program removes them and keeps them out: $445 at the first visit, then $150 a quarter (homes up to 2,000 sq ft) — inside and outside stations, seal-up at week 3, quarterly inspections, 12-month warranty.

Our Process
How Sani IQ Handles Mice in Toronto
Full inspection + entry-point map
Exterior foundation, garage seals, utility lines, weepers, attic and kitchen kick-plates — we document every gap a mouse can use (a dime-width, about 6 mm, is enough). Most homes have 8–15 the owner has never noticed.
Treat first — exit routes stay open
Interior treatment plus tamper-resistant exterior bait stations, placed on the evidence (droppings, rub marks, gnaw patterns). We deliberately do NOT seal on day one, so mice leave the structure and die outside — not in your walls.
Return visit (~3 weeks): verify, then seal
Once activity has stopped we come back, confirm the knockdown, and seal the entry points with galvanized steel mesh, steel-wool-backed sealant and weatherstripping. Sealing at the right time is the step most companies get wrong.
Keep them out + 12-month warranty
Stations stay in and are serviced every quarter; freeze-thaw and settling open new gaps, so we re-inspect and reseal on every visit. Mice return inside the warranty? So do we — at no charge.
Where They Get In
The 8 Ways Mice Get Into Toronto Homes
Our inspections in Toronto find 8–15 entry points on a typical house. These are the ones that show up again and again — and the ones we seal at the ~3-week return visit, once the mice are out.
- 1 Garage door bottom seal — Worn weatherstrip = open door
- 2 Weepers & foundation cracks — 6 mm is enough
- 3 Utility & A/C line penetrations — Gas, hydro, cable, condensate
- 4 Dryer & bathroom vents — Missing or stuck flaps
- 5 Soffit & fascia gaps — Climb via downspouts and vines
- 6 Roofline & attic vents — Then straight down the wall voids
- 7 Window wells & sill gaps — Basement windows left ajar
- 8 Cantilevers & deck ledgers — Open-bottom overhangs

Mice Control in Toronto — FAQs
How much does a mice exterminator cost in Toronto?＋
Mice inside in Toronto? The Sani IQ Rodent Program is $445 at the first visit, then $150 a quarter for homes up to 2,000 sq ft: removal in three weeks, every entry point sealed, stations kept in all year with quarterly inspections and a 12-month warranty. Bills after each visit — no monthly fees. Prefer one visit pair? One-Time Mice is $495 with a 60-day warranty.
I live in a condo — can you treat mice?＋
Yes. Condo and apartment mice jobs are a Toronto specialty: we treat your unit, identify how mice are travelling (pipe chases, kick-plates, shared voids), and document findings you can give your property manager so the building-level source gets fixed too.
Why do I have mice if my home is clean?＋
Cleanliness has little to do with it — Toronto mice need warmth and access, not mess. Old foundations, gaps around utility entries and shared walls are the real causes, which is why our jobs always include exclusion, not just bait.
Do you offer same-day mice service in Toronto?＋
Yes, subject to availability — call (705) 302-1887 and we'll give you a window, usually same-day or next-day anywhere in Toronto.
Why don't you seal the entry points on the first visit?＋
Because sealing first traps mice inside — they die in wall voids and you get the smell for weeks. Our exit-first protocol treats on day one with exit routes open so mice leave and die outside, then we return in about three weeks to verify the knockdown and seal. Sealing is included; it's the sequence that matters.
Will the mice leave on their own once it gets cold or warms up again?＋
No. Mice move in for warmth and food in October–November and, once established, a house is better than outdoors in every season. A population that has nested inside grows through winter — a female can have 5–10 litters a year. Waiting makes it a bigger job, not a smaller one.
How will I know they're actually gone?＋
You'll see it in the evidence: no fresh droppings, no new gnawing, no night-time scratching. We confirm it at the ~3-week return visit before sealing, and the quarterly station checks catch any new exterior pressure before it becomes an indoor problem again.
How should I prepare for a mice treatment visit?＋
Very little — clear access to the kitchen kick-plates, under-sink cabinets, furnace room and garage walls, and keep pets away from the areas we're working in. Our Help Centre has a short checklist: how to prepare for a mice treatment (saniiq.com/helpcentre/prepare-for-mice-treatment/).
