Mice Control Ontario — Out of Your Walls, for Good
Most companies seal on day one — and mice die inside your walls. Our exit-first protocol treats first so mice leave and die outside, then we return in ~3 weeks to verify and seal. Done properly, in two visits.
A female mouse can produce 5–10 litters per year (up to 60 offspring)
Mice can squeeze through a 6mm gap — the width of a pencil
Rodents chew electrical wiring — a leading cause of house fires
Mice spread hantavirus, salmonella, and other pathogens through droppings
Warning Signs
How to Know You Have Mice & Rats
Early detection is the key to fast, cost-effective elimination. Here's what to look for:
- ✓ Droppings along walls, in cabinets, under sinks (dark, rice-sized pellets)
- ✓ Gnaw marks on food packaging, wood trim, or wiring insulation
- ✓ Scratching or scurrying sounds in walls or ceiling at night
- ✓ Nesting material (shredded insulation, paper, fabric) in hidden areas
- ✓ Grease rub marks along walls and baseboards from repeated travel paths

Mice & Rats in Ontario
Species Found in Ontario Homes
House Mouse (Mus musculus)
Ontario's most common indoor rodent. Small, grey-brown, 7–10cm. Excellent climbers. Nest in wall voids, attics, and behind appliances.
Deer Mouse (Peromyscus maniculatus)
Tan/white colouring with large ears. Primary carrier of hantavirus. More common in rural Ontario and cottage country.
Norway Rat (Rattus norvegicus)
Much larger than mice — up to 40cm including tail. Burrow under foundations. Can cause significant structural damage and contaminate food stores.
Roof Rat (Rattus rattus)
Slimmer and more agile than Norway rats. Climb trees and enter via rooflines. Less common in Ontario but present in GTA.
Our Process
How We Eliminate Mice & Rats
A science-based, 4-step approach that treats the root cause — not just the symptoms.
Full Inspection + Entry Point Mapping
We inspect your entire property — interior and exterior — documenting every gap, crack, and penetration where rodents can enter. Most properties have 8–15 entry points the homeowner hasn't noticed.
Treat First — Exit Routes Stay Open
We place interior treatment and commercial-grade exterior bait stations based on evidence (droppings, rub marks, gnaw patterns). We deliberately do NOT seal on day one — exit routes stay open so mice leave the structure and die outside, not inside your walls.
Return Visit (~3 Weeks): Verify & Seal
Once the population is knocked down, we return to verify activity has stopped and seal minor entry points with professional-grade materials: galvanized steel mesh, expanding foam with steel wool, and weatherstripping. Sealing at the right time is what most companies get wrong.
Ongoing Protection + Guarantee
For properties with higher exterior pressure — ravine lots, farmland edges, older homes — our Mice Protection plan ($895/yr) keeps exterior stations serviced and the barrier maintained through all four Ontario seasons.

Common Questions
Mice & Rats Control — FAQ
How much does mice control cost in Ontario?
Complete Mice Protection is $495 — two visits, three weeks apart: treatment plus exterior bait stations first, then verification and sealing. A basic single-visit treatment is $345. For high-pressure properties, our Mice Protection plan is $895/year with 4 quarterly visits.
I only saw one mouse. Is that a big deal?
One mouse typically means more. Mice are nocturnal and cautious — if you see one during the day, the population is likely large enough that competition for food is pushing them into the open. Act early: a small problem is much easier and cheaper to resolve.
Are your rodent treatments safe for pets?
Yes. We use tamper-resistant bait stations that are inaccessible to pets and children. The specific bait formulations we use are also selected for minimal risk to secondary poisoning in household pets.
Do you seal the entry points?
Yes — but not on day one, and that's deliberate. Seal too early and mice die inside your walls. We treat first so mice exit and die outside, then return in about three weeks to verify knockdown and seal minor entry points. Sealing is part of the service, sequenced correctly.
Where do the mice go to die?
Outside — by design. Because we keep exit routes open during treatment and control the exterior population with commercial-grade bait stations, mice leave the structure rather than dying in wall voids. That's the difference between our exit-first protocol and seal-first approaches.
How long does it take to get rid of mice?
Most active infestations show significant improvement within 1–2 weeks of treatment. Full resolution — verified knockdown plus sealing at the ~3-week return visit — typically completes within a month. Quarterly monitoring keeps the barrier effective across seasons.
Can mice come back after treatment?
If exclusion isn't done properly, yes. That's why our Mice Protection plan includes quarterly visits — Ontario's freeze-thaw cycles and construction can open new gaps. We inspect and reseal every visit.
