Mice are among the most common pests in homes and businesses in Montreal.
They sneak through cracks, attics, or pipes to find warmth and food, often in the fall or winter.
Signs of an infestation:
Scratching noises in the walls or ceiling
Droppings in closets or the kitchen
Persistent odor in certain rooms
Damage to electrical wires and insulating materials
Ignoring these signs can lead to a severe infestation, causing health risks (salmonellosis, hantavirus) and costly damage.
Our certified technicians thoroughly inspect high-risk areas—walls, basements, attics, and closets—to identify entry points and the source of the infestation.
We apply effective and sustainable treatments that are approved by Health Canada and comply with Quebec's Ministry of the Environment.
After removal, we seal all possible openings using galvanized wire mesh and high-density foam to prevent reinfestation.
A follow-up inspection is included to verify the effectiveness of the treatment and ensure long-lasting protection against mice returning.

In most cases, no. The treatment is designed to be carried out without the occupants having to leave. However, if the infestation is very severe or if sealing work is required (attic, crawl space), specific instructions will be provided during the initial inspection.
Black, rice-grain-shaped droppings, often near walls or cupboards
Scratching or moving noises at night in the walls/ceilings
Damage caused by gnawing: cables, food packaging, insulation
Grease marks or signs of passage near baseboards or ducts
If you notice one or more of these signs in Montreal or the surrounding area, a quick inspection is recommended.
Prevention is essential. Here is some advice from our technicians:
Seal all cracks and holes around pipes and baseboards.
Install brushes under exterior doors
Store food in airtight containers and clean up crumbs.
Close and move trash cans away from walls
Perform a annual preventive inspection, even without visible signs
These practices prolong eradication and greatly reduce the risk of recurrence.
