Every winter, thousands of Quebec families discover mice in their house or apartment. Attracted by warmth and food, they infiltrate homes as soon as temperatures drop. At Montréal, Laval or on the North Shore, These small rodents cause many problems: noise, odor, property damage, and health risks. But why do they invade our homes? And above all, how can we get rid of them effectively and permanently?

At Extermi Pro Inc. our experts intervene 7 days a week throughout Greater Montreal. We offer professional mouse control treatments with warranty, inspection, and sealing included on the second visit.

Why mice are invading Quebec homes

When the cold weather sets in, mice look for a warm, safe shelter close to a food source. Homes with Ahuntsic, Villeray, Rosemont or Plateau-Mont-Royal, often old, have cracks, open pipes, and crawl spaces that become perfect passageways. An opening of 6 mm is enough for a mouse to get in!

According to the City of Montreal, The presence of waste, accessible food, or poorly sealed cracks is the main cause of infestation in urban buildings. This is why rodents often settle in kitchens, basements, and attics.

Clear signs of a mouse infestation

• Excrement : small black grains measuring 3 to 6 mm, often found near the stove or refrigerator; ;
• Scratching noises : audible at night in walls, ceilings, or closets; ;
• Urine odors persistent, especially in corners or under sinks; ;
• Teeth marks on plastic, wood, or electrical cables; ;
• Pierced food packaging or destroyed.

Expert tip: Mice always run along walls. If you notice dark marks on the baseboards, this is a sign of frequent and active passage.

Risks associated with the presence of mice

An infestation does not just cause inconvenience: it presents real health and safety risks. Mice carry bacteria, viruses, and parasites (salmonella, leptospirosis, mites, fleas) and their droppings can contaminate food. They also gnaw on electrical cables, sometimes causing short circuits and even fires.

How to prevent a mouse infestation

• Inspect carefully your foundations, baseboards, and pipes; ;
• Seal the cracks with wire mesh or steel wool; ;
• Store food in airtight containers; ;
• Clean regularly the areas behind appliances; ;
• Quickly dispose of waste to avoid attracting rodents; ;
