Mouse Exterminator in Montreal

How do mice get into your home?

In Montreal, mice are mostly looking for warmth, food and shelter, especially when temperatures drop. Older buildings, triplexes, basements, garages and apartment buildings can offer several easy access points.

Cracks, doors, windows and exterior openings

Mice can get in through cracks in the foundation, gaps under doors, poorly sealed windows, holes around cables and openings near pipes.

Even a small opening can become an access point. That’s why the exterior inspection is just as important as the interior treatment.

Roof, chimney, ducts and plumbing systems

Mice can also get into a building through the roof, gutters, vents, chimneys, ducts or certain openings connected to the plumbing.

In older Montreal buildings, hidden access points are common. Walls, ceilings, basements and attics then become travel routes for rodents.

Boxes, stored furniture and cluttered areas

Mice like quiet, cluttered places. They can nest in storage boxes, upholstered furniture, stored mattresses, garages, sheds, basements and rarely used rooms.

Cardboard, fabric, paper and insulation often serve as materials for building their nests.

What attracts mice into your home?

A mouse infestation is often linked to favourable conditions in or around the building. By correcting these factors, you increase the chances of lasting control.

Mice are attracted by:

• accessible food;
• crumbs and food scraps;
• pet food;
• poorly closed garbage bins;
• water bowls;
• dripping faucets;
• damp basements;
• warm attics;
• cluttered areas;
• vegetation near the building;
• unsealed openings.

To reduce the risks, keep food in airtight containers, close garbage properly, clean food preparation areas and clear the area along the building’s exterior walls.

When should you call a professional mouse exterminator?

It’s best to call an exterminator at the first signs. The faster the intervention, the easier it is to control the infestation before it spreads into the walls, ceilings or other units.

Droppings, odours and noises in the walls

Mouse droppings are often visible in cabinets, under the sink, near baseboards, in the pantry or around appliances.

A strong odour, especially in an enclosed area, can indicate rodent activity. Scratching noises in the walls, ceilings or floors are also common, especially at night.

Bite marks, nests and gnawed packaging

Mice gnaw food packaging, cardboard, wires, insulation, wood and certain building materials. If you find bite marks or shredded materials, a nest may be nearby.

Unusual behaviour from your pets

Dogs and cats can detect mouse activity before the occupants do. If they stare at a wall, scratch at a specific spot or react to an invisible noise, there may be rodents in the building.
