✅ Rapid response – ✅ Health Canada-certified products – ✅ Warranty up to 6 months

Professional and secure solutions against rats and mice

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:

Complete inspection of risk areas

Detailed inspection of foundations, walls, and basements to detect any rat or mouse activity in Montreal.

Setting traps and secure stations outdoors and indoors

Installation of professional bait stations that are secure and effective against rodents.

Permanent sealing of access points

Complete sealing of cracks and openings used by rats and mice to enter buildings.

Follow-up after treatment to prevent reinfestation

Post-treatment verification, prevention advice, and ongoing monitoring to ensure a rodent-free space in the long term.

How to recognize a Rat infestation?

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.

Professional inspection and sealing

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.

Comprehensive approach to pest management

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.

Focus on rats in Montreal

  • 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.

Hidden damage caused by rats in buildings

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.

Prevent the return of Rats

  • 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.
