Mice Control Ontario — Seal Them Out for Good
Mice can enter through a gap the size of a dime. Our exclusion-first approach finds and seals every entry point — then eliminates what's already inside.
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.
Baiting & Trapping
We install tamper-resistant bait stations and traps in strategic locations following Interior and Exterior rodent activity patterns. No guessing — we place based on evidence (droppings, rub marks, gnaw patterns).
Exclusion & Sealing
We seal identified entry points using professional-grade materials: galvanized steel mesh, expanding foam with steel wool, and weatherstripping. This is the step most companies skip.
Monitoring + Guarantee
We schedule follow-up monitoring and include return visits if activity continues. Our Mice Protection plan ($895/yr) provides quarterly visits to maintain the barrier through all four Ontario seasons.

Common Questions
Mice & Rats Control — FAQ
How much does mice control cost in Ontario?
Our Mice Protection plan is $895/year, covering 4 quarterly visits — inspection, treatment, and exclusion maintenance every season. One-time treatments are also available; pricing depends on property size and activity level.
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 — exclusion (sealing) is a core part of our treatment, not an add-on. Most companies only bait and trap, which means mice keep coming back through the same entry points. We physically block re-entry.
How long does it take to get rid of mice?
Most active infestations show significant improvement within 1–2 weeks of treatment. Full resolution with exclusion typically takes 2–4 weeks. Our quarterly monitoring ensures the barrier stays 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.
