Mice Problems in Mississauga? Here's How We End Them.
Mississauga's mix of mature neighbourhoods like Streetsville and Port Credit, newer subdivisions, and high-density condo corridors around Square One gives mice everything they need — older foundations with settled gaps, shared walls, and construction activity that pushes rodents into nearby homes. Sani IQ treats Mississauga mice problems at the source: we don't just put down bait, we find and seal the entry points so they stay out.
Signs You Have Mice in Your Mississauga Home
- Droppings along baseboards, under the kitchen sink, or in the garage
- Scratching sounds in walls or ceilings — especially at night
- Gnaw marks on food packaging, wiring, or wood
- A musky ammonia smell in enclosed areas like pantries and closets
- Pets fixating on one wall, appliance, or cabinet

Our Process
How Sani IQ Handles Mice in Mississauga
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 Mississauga Homes
Our inspections in Mississauga 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 Mississauga — FAQs
How much does mice control cost in Mississauga?＋
Mice inside in Mississauga? 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.
How do mice get into Mississauga homes?＋
The most common entries we find in Mississauga are gaps where utility lines enter the foundation, worn garage door seals, and openings under porches and additions — anything the width of a dime is enough. Sealing these is part of every Sani IQ mice job.
Is the treatment safe for kids and pets?＋
Yes. We use tamper-resistant, locked bait stations and place snap traps only in areas children and pets can't reach. Everything we use is Health Canada–registered and explained to you before we start.
How fast can you get to my Mississauga home?＋
Same-day and next-day appointments are usually available across Mississauga. Call (705) 302-1887 and we'll give you a real arrival window.
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/).
