Mice Control in Oshawa
Treated on day one, verified at three weeks, then sealed — 12-month warranty, no monthly fees. November is the peak move-in month in Ontario.
Oshawa gives mice more openings than almost any city in Durham. The GM-era wartime housing through Lakeview and the south end has settled foundations, original service lines and decades of small gaps; the century homes around O'Neill and downtown add aging brick and stone; and up north, Windfields and Kedron subdivisions sit against open farmland that pushes field mice indoors every fall. Sani IQ treats Oshawa mice problems at the source — we map every entry point and seal them, so mice stay out instead of cycling back.
Where we find them getting in around Oshawa
- Droppings along baseboards, under the kitchen sink, or in the garage
- Scratching or scurrying in walls and ceilings after dark
- Gnaw marks on food packaging, wiring or wood trim
- A musky ammonia smell in the basement, pantry or furnace room
- Activity that spikes each fall as nearby fields are harvested
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 Oshawa Homes
Our inspections in Oshawa 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 in Oshawa — common questions
Why do older Oshawa homes get so many mice?
The wartime housing in Lakeview and the south end was built fast in the 1940s-50s — settled foundations, original utility penetrations and gaps a dime-width wide are everywhere. Mice don't need much. Sealing those entry points, not just baiting, is what actually ends the problem, and it's the step we never skip.
Do you treat student rentals near Ontario Tech and Durham College?
Yes — north Oshawa rentals see heavy turnover, and mice move in during quiet months. We work with both tenants and landlords, and our documentation is suitable for property managers.
How do mice get into Oshawa homes?
The entries we find most in Oshawa: gaps where utility and A/C lines enter the foundation, worn garage-door bottom seals, weepers and foundation cracks, dryer and bathroom vents with stuck flaps, and soffit or fascia gaps at the roofline. A house mouse needs about 6 mm — the width of a dime. Mapping and sealing every one of them is part of every Sani IQ mice job in Oshawa.
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.

Oshawa's Rat Surge Is Real — and Its Geography Explains It
Oshawa's south end tells the story: a century of industry, post-war housing on settled foundations, and the Oshawa Creek corridor running straight through it all. Rats that established during the GM era never left — they just moved with the food. The older neighbourhoods below the 401, and the streets around downtown, see the steadiest rodent pressure in Durham.
North Oshawa is a different city: Windfields and Kedron's new construction displaces field mice into finished streets every phase, and the student-rental belt around Ontario Tech and Durham College turns over twice a year — which is exactly how bed bugs and cockroaches travel.
Every technician is employed, licensed under the Ontario Pesticides Act, and background-checked.
What Oshawa Calls Us For
Rats in the south end and along the creek — exclusion-first, then bait and monitor, because in older housing the entry points are the problem. Mice everywhere from first frost. Bed bugs and cockroaches in the student corridors, handled discreetly with landlord documentation when needed. Wasp nests across the older tree-lined wards all summer. And ant surges every June — Oshawa's clay-heavy soils push pavement ants up through every driveway and patio in the city.
Same-day service is available across Oshawa and Durham most weekdays.
What It Costs in Oshawa
Homes in Oshawa are billed after each visit — no monthly fees. Sani IQ Protect is $249 a visit, four visits a year, for homes up to 2,000 sq ft.

Frequently Asked Questions
How much does pest control cost in Oshawa?
Sani IQ bills every visit after it's done — no monthly fees. Mice inside in Oshawa? The Sani IQ Rodent Program is $445 at the first visit, then $150 a quarter, 12-month warranty. Want the whole house covered? Sani IQ Protect is $249 a visit, four visits a year, rodent prevention included. Mice and insects together? Protect Plus is $249 a visit (six visits). Base prices cover homes up to 2,000 sq ft. Bed bugs, German cockroaches, wildlife and rats are quoted after an inspection.
Why is my south Oshawa street seeing more rats?
Established populations plus disturbance. Rats have been part of south Oshawa's infrastructure for a century, and every demolition, sewer job or big dig relocates them. We seal entries first, then bait and monitor — bait boxes alone just feed the block.
I'm a landlord near Ontario Tech — can you treat between tenants?
Yes. Turnover weeks are the right time to treat and document. We handle bed bugs and cockroaches discreetly and provide the documentation you need, with guarantees on treatment.
Why does my new Windfields home have mice already?
New construction displaces the field rodents that lived on that land, and new builds are rarely sealed to pest standard. One exclusion visit now saves years of bait boxes.
Do you serve all of Durham from Oshawa?
Yes — Whitby, Ajax, Pickering, Courtice and Bowmanville are all on the same routes. Same-day is usually available. Call (705) 302-1887.
