Rats are among the most feared pests in Montreal. Capable of gnawing through walls, damaging electrical cables, and spreading disease, they pose a real threat to health and safety.
At Extermi Pro, we offer professional treatments against rats and other rodents, including inspection, pest control, sealing, and written warranty.
✅ Rapid response – ✅ Health Canada-certified products – ✅ Warranty up to 6 months
Our pest control experts in Montreal treat all types of rodents, including Norway rats (brown rats) and house mice.
Although these two species differ in size, their behavior is similar: they enter through small cracks, contaminate food, and cause significant property damage.
Our integrated approach:
Detailed inspection of foundations, walls, and basements to detect any rat or mouse activity in Montreal.
Installation of professional bait stations that are secure and effective against rodents.
Complete sealing of cracks and openings used by rats and mice to enter buildings.
Post-treatment verification, prevention advice, and ongoing monitoring to ensure a rodent-free space in the long term.
The signs are often similar to those of a mouse infestation, but more pronounced:
Noises of loud scratching in the walls, floor, or ceiling
Larger droppings (1 to 2 cm) along walls or behind appliances
Snack food and strong smell of urine
Visible holes near foundations or pipes
⚠️ If the noises are faint and concentrated around the kitchen or pantry, it could also be mice. In both cases, a professional inspection is quickly becoming essential.
Each treatment begins with a thorough inspection of your building:
Search for openings around foundations, water ingress, and wall cracks
Inspection of ventilation ducts, basements, and cavity walls
Analysis of rodent activity using detectors and cameras
We then proceed to completely seal off access points with professional mesh and sealants, preventing rats and mice from returning.
At Extermi Pro, we don't just eliminate visible rats.
We eliminate the source of the problem by treating access points, shelters, and breeding areas.
By choosing Extermi Pro, you benefit from a local, fast, and guaranteed service, directed by certified technicians and equipped with professional equipment.
Advantages to list:
Brown rat (Norway rat) : the most common in Montreal. It lives in sewers and basements and digs tunnels.
Black rat : easily climbs roofs and ceilings, rarer but just as destructive.
Gray mouse : Smaller, it can get everywhere. Although it seems less alarming, it causes just as much contamination and reproduces quickly.
A single pair of rats can produce more than 200 offspring per year, and a colony of mice can multiply even faster.
Rats don't just get into walls:
They chew on electrical wires, increasing the risk of fire.
They weaken insulation by digging tunnels in the walls and ceilings.
They contaminate ventilation ducts, which spreads bacteria and odors.
Their acidic excrement damages materials such as wood or plaster.
🔎 Our technicians inspect every critical area to identify invisible damage before it becomes costly to repair.
Effective extermination is not enough without sustainable prevention.
Our experts implement a comprehensive strategy to prevent any recurrence:
Quarterly preventive inspection risk areas (basement, garage, attic).
Permanent clogging cracks, pipes, and exterior joints.
Cleaning and removal of food sources (grains, leftovers, poorly closed trash cans).
Foundation protection and ventilation openings with metal grilles.
Professional follow-up to quickly detect any new rat or mouse activity.
💡 These simple steps, combined with regular maintenance, can prevent 90% of reinfestations in residential and commercial buildings.

Rats are larger, leave larger droppings, and cause more damage. Mice are smaller and can squeeze through tiny cracks. Professional treatment differs depending on the species.
Rats spread diseases (leptospirosis, salmonellosis), contaminate food, and damage electrical cables, increasing the risk of fire.
A complete treatment generally lasts 7 to 14 days, depending on the size of the colony. Monitoring and preventive sealing ensure long-lasting results.
