The major families of pest rodents in Quebec
Each rodent family has its own behaviour, preferred zones, and specific treatment methods. Precisely identifying the species is the first step toward effective extermination: a Norway rat isn’t treated the same way as a house mouse.
Commensal rodents
Common mice and structural rats. Species that live alongside humans, exploiting heating areas, food sources, and hiding spots in walls and ceilings.
Field rodents
Voles and field mice. Increased presence in fall when cold drives them to seek indoor shelter. Damage to gardens, lawns, foundations, and outdoor lumber.
Aquatic rodents
Muskrats and sewer rats. Found along waterways, in municipal sewers, damp foundations, and flood-prone basements.
Arboreal rodents
Squirrels, chipmunks, and groundhogs. Biologically rodents, but handled as wildlife due to Quebec's regulations on wild species.
The most treated rodents in Quebec
Six species account for the vast majority of calls received by our rodent exterminators. Each species has its own treatment protocol, seasonality, and infestation signs. Click a species to discover our detailed treatment methods.
House mouse
The most treated species in Quebec. Small (7–10 cm), grey or brownish, can squeeze through a 6 mm opening. Rapid reproduction: one pair can produce over 200 descendants per year.
Mouse controlNorway rat
Also known as the brown rat, Norway rat, or sewer rat (Rattus norvegicus). The largest rat found in Quebec (20–25 cm without the tail). Lives mainly at ground level, in basements, sewers, and foundations.
Norway rat controlBlack rat
Also known as the roof rat (Rattus rattus). Smaller and more agile than the Norway rat. Nests up high: attics, drop ceilings, trees, and rooftops. Less common in Quebec but on the rise.
Black rat controlVoles and field mice
Small rodents of fields and underbrush. Increased presence in fall when they seek winter shelter. Damage to gardens, outdoor electrical conduits, and foundations.
Vole controlMuskrat
Large aquatic rodent found near waterways, marshes, and ditches. Causes damage to dykes, banks, and water-management structures. Specialized treatment required.
Muskrat controlEastern chipmunks
Small striped rodents, often confused with squirrels. Biologically rodents but handled as wildlife. Dig tunnels under decks, patios, and foundations.
View wildlife removalThe Pestora method applied to rodents
Four structured steps tailored to each rodent species, from identification through to lasting exclusion. Simple surface trapping won’t resolve an established infestation.
01/ Full inspection
Species identification, locating of entry points, nesting areas, and food sources. Mapping of pathways, droppings, and visible damage both inside and outside the property.
02/ Targeted elimination
Safe solution: Use of bait stations (mechanical traps and Health Canada-approved anticoagulants), adapted to the species, environment, and the presence of children or pets.
03/ Exclusion and sealing
Sealing of every identified entry point: foundation cracks, pipe penetrations, ventilation openings, gaps under doors. Without physical exclusion, the infestation will return.
04/ Follow-up and prevention
Follow-up inspection two to three weeks after the intervention to confirm elimination. Preventive recommendations on waste management, food storage, and exterior landscaping. Written warranty.
Rodents aren’t just a visual nuisance. They pose three major risks: health (transmission of hantavirus, leptospirosis, salmonella, and other pathogens via droppings and urine), structural (gnawing on electrical wires — a documented cause of many residential fires each year in Quebec — destruction of insulation, damage to framing and plumbing), and economic (contamination of stored goods, inventory loss in commercial settings, potential loss of MAPAQ or HACCP certification). Add to that rapid reproduction: an untreated pair of mice can produce over 200 descendants in a year. The earlier the intervention, the simpler, more targeted, and more economical it is.

How do I know if I have a rodent infestation?
Several signs indicate an active presence: droppings (small dark elongated pellets near baseboards, in cabinets, or in storage areas), scratching sounds in walls or ceilings at night, a particularly strong urine odour in enclosed spaces, grease marks along walls (rodent travel paths), gnawed food packaging, and nesting materials (shredded paper, insulation). A single mouse usually suggests an established colony.
What are the main risks of rodents?
Three risk categories. Health: rodents carry hantavirus, leptospirosis, salmonella, and several other pathogens transmitted via droppings, urine, and bites. Structural: they gnaw on electrical wires (a documented cause of multiple residential fires each year in Quebec), insulation, wood, and plumbing. Economic: contamination of stored goods, inventory loss for businesses, and risk of non-compliance with MAPAQ or HACCP standards in food settings.
How do rodents enter a home?
A mouse can fit through an opening as small as 6 millimetres (about the size of a pencil), a rat through 12 millimetres. Typical entry points are foundation cracks, pipe and electrical wire penetrations, unscreened ventilation openings, gaps under garage doors, damaged soffits, and openings around exhaust vents. Systematic exterior inspection is the first step to any lasting exclusion.
How long does rodent control take?
For a typical household infestation, complete elimination usually takes 2 to 4 weeks. First visit: inspection, placement of bait stations and traps, identification of entry points. Follow-up visit 2–3 weeks later: removal of devices, sealing of access points, confirmation of elimination. For larger commercial or industrial infestations, a multi-month integrated pest management program may be recommended.
Are your treatments safe for children and pets?
Yes. All baits used by our exterminators are Health Canada-approved and placed in secured bait stations, inaccessible to children and pets. For at-risk areas, our technicians may prefer mechanical traps (no poison) or physical exclusion approaches. Every intervention is adapted to the presence of vulnerable occupants, with clear safety instructions.
How do I prevent a rodent infestation?
Several measures significantly reduce risk: storing food in airtight containers, managing trash bins with tightly sealed lids, eliminating standing water sources, systematic sealing of cracks and entry points, trimming vegetation away from foundations, removing firewood stored against the house, and regular cleaning of basements and attics. For businesses and industrial facilities, a documented preventive program is the most effective solution.
Are squirrels considered rodents?
Biologically, yes: squirrels, chipmunks, and groundhogs belong to the order Rodentia. However, under Quebec’s regulatory framework, they’re considered wildlife and their management is governed by specific rules on capture and relocation. At Pestora, we treat these species under wildlife removal, separate from services for mice, rats, and voles.
How much does rodent control cost?
Rates vary based on species, infestation scale, area to be treated, and property type. A residential intervention for a moderate mouse infestation differs significantly from a rat control program for an industrial warehouse. All our assessments are free, with a fixed price communicated before any commitment. The cost of a professional intervention is consistently lower than the cost of repairs and losses from an untreated infestation.
