How Much Does Mice Control Cost in Ontario? (2026 Price Guide)

Quick answer: Mice control cost in Ontario in 2026 typically runs $345 for a basic single-visit knockdown and $495 for a complete two-visit program that includes sealing minor entry points on the follow-up. At Sani IQ, Complete Mice Protection is $495; a year-round plan for high-pressure homes is $895. Prices below are exact, not estimates.

If you’ve spotted droppings under the sink or heard scratching in the wall at 2 a.m., the first thing you want is a number — what does it actually cost to make mice control someone else’s problem? In a well-run Ontario home, the standard is zero mice, not “a few in the garage.” This guide gives you real 2026 mice control cost ranges, explains exactly what each price includes, and helps you weigh doing it yourself against booking a professional and forgetting about it.

One mouse is rarely just one mouse. A single female house mouse can produce 5 to 10 litters a year, with several pups in each (Critter Control). That’s why the cost question and the timing question are really the same question: the longer the wait, the bigger the job.

How much does mice control cost in Ontario in 2026?

Most Ontario homeowners pay between $345 and $495 for professional mice control, depending on whether they want a single knockdown or a complete program that ends with sealing. Year-round protection plans run higher because they include ongoing monitoring. Here are Sani IQ’s exact 2026 prices alongside typical market ranges.

Service	Sani IQ 2026 price	What it includes
Basic mice treatment (single visit)	$345	One visit: inspection, interior treatment, exterior bait stations. No sealing.
Complete Mice Protection (recommended)	$495	Two visits ~3 weeks apart. Visit 2 verifies knockdown and seals minor entry points.
Year-round Mice Protection plan	$895/yr	Ongoing monitoring and protection for high-pressure properties.
Typical Ontario market range	$200–$550	Trapping or bait + monitoring; exclusion/sealing often $400–$800 extra (ProTasker, This Old House)

Note the gap many companies leave out: across the market, sealing entry points (“exclusion”) is frequently billed as a separate $400–$800 job. With Sani IQ’s $495 Complete Mice Protection, sealing of minor entry points is built into the second visit.

What’s the difference between the $345 and $495 mice service?

The $345 service is a single-visit knockdown: inspection, interior treatment, and commercial-grade exterior bait stations — no sealing. The $495 Complete Mice Protection adds a second visit about three weeks later to verify the mice are gone and seal minor entry points. For most homes, $495 is the one that actually ends the problem.

Here’s the part homeowners get wrong about sealing: a reputable program does not seal your home on day one. If you seal entry points while mice are still active inside, you trap them in your walls — and that’s exactly where you don’t want them dying. Sani IQ deliberately leaves exit routes open during treatment so mice feed on the exterior bait stations, leave, and die outside. Sealing happens on the second visit, once activity has dropped. That sequence is the difference between “I think they’re gone” and “they’re gone, and they can’t get back in.”

Should I get rid of mice myself or hire a professional?

You can buy traps for under $20, so DIY looks cheaper on paper. The real cost is your time and the relapse risk: DIY means daily trap checks, hunting down every entry point, and weeks of monitoring — often followed by mice returning because the source was never sealed. Below is the honest trade-off so you can decide what your time is worth.

Factor	DIY (traps & store bait)	Sani IQ Complete Mice Protection ($495)
Upfront cost	$20–$100	$495 (two visits, sealing included)
Your time	Daily trap checks, sealing, weeks of monitoring	One inspection appointment; we handle the rest
Sealing entry points	You find and seal them — or they come back	Minor entry points sealed on visit 2
Risk of relapse	High — source often missed	Backed by our “Pest-Free, OR It’s Free” guarantee
Where mice die	Often inside walls (odour)	Outside, by design — exit routes stay open during treatment

DIY isn’t “wrong” — but for a busy household, the math usually favours booking it once and being done. If you’d rather not spend three weeks playing exterminator, professional service is the time-respecting choice.

Why is professional mice control worth it? (the real stakes)

Mice are an expensive problem disguised as a cheap one. As they travel, they constantly dribble microdroplets of urine and leave droppings that can carry bacteria like Salmonella and E. coli (Critter Control). They also gnaw — and wiring is a favourite target. A widely cited Pest World report estimates rodents are responsible for up to 25% of house fires where the cause is otherwise undetermined (Best Life). Set against that, $495 to resolve the issue properly is a reasonable number.

Sani IQ’s mice pricing is the same across our Ontario service area — $345 basic, $495 complete, $895/yr plan — whether you’re in Richmond Hill, Markham, or further out. Pricing transparency is deliberate: you shouldn’t need a “free inspection” sales call to learn what a job costs. We publish it. See full pricing on our plans and pricing page.

Local pressure does vary. Older homes, properties backing onto fields or ravines, and homes with attached garages tend to see more rodent activity, which is why high-pressure properties are the ones we steer toward the $895/yr year-round plan.

What should I check before mice get inside? (5 steps)

You can’t out-trap an open door. These steps reduce pressure between professional visits — they are prevention checks, not a treatment plan:

1. Walk your foundation. Mice fit through a gap the width of a pencil (about 6 mm). Look for gaps around the foundation, vents, and where pipes enter.
2. Check the garage. Attached garages are the most common entry route; keep the door seal intact and pet food in sealed containers.
3. Trim back vegetation. Branches and tall grass touching the house act as bridges and cover.
4. Store food in metal or glass. Cardboard and thin plastic are not barriers.
5. Note where you see droppings. Photograph the spots — it helps your technician map travel routes on the inspection.

Frequently asked questions

How much does it cost to get rid of mice in Ontario? In 2026, expect $345 for a basic single-visit knockdown and $495 for a complete two-visit program that includes sealing minor entry points. Year-round plans for high-pressure homes are $895. Market-wide, single treatments run roughly $200–$550, with sealing often billed separately.

Does mice control include sealing the entry points? With Sani IQ’s $495 Complete Mice Protection, yes — minor entry points are sealed on the second visit, about three weeks in. The $345 basic service is knockdown only, with no sealing. Sealing is deliberately done later so mice aren’t trapped inside the walls.

Why don’t you seal the holes on the first visit? Because mice are still active inside. Sealing day one traps them in your walls, where they die and create odour. We leave exit routes open during treatment so mice feed on exterior bait stations, leave, and die outside — then we seal on visit 2 once activity drops.

Is it cheaper to get rid of mice myself? The traps are cheaper, but DIY costs you daily checks, weeks of monitoring, and a high chance the mice return because the entry point was never found. For a busy household, the $495 program that ends with sealing is usually the better value once your time is counted.

How quickly do mice multiply? Fast. A single female house mouse can produce 5 to 10 litters a year with several pups each (Critter Control). That’s why one mouse is the start of a problem, not a minor one — and why acting early keeps the cost down.

Do you guarantee the work? Yes. Sani IQ backs mice control with our “Pest-Free, OR It’s Free” guarantee: we re-treat as needed, and if the problem isn’t resolved, you get a refund. Pricing and guarantee details are on our plans and pricing page.
