Every autumn, Villeray residents face the same phenomenon: mice seek refuge inside homes to escape the cold. This isn't a coincidence – it's predictable behavior linked to Quebec's climate conditions and the neighborhood's building structures.

In short: Mice invade Villeray homes as soon as nighttime temperatures drop below 10°C. Cracks in foundations, openings around plumbing, and worn door thresholds are the main entry points. Prevention begins before the first frost.


Villeray: Why the mouse are frequent here

The Villeray neighborhood exhibits characteristics that encourage the presence of mice. The density of housing, the age of the buildings, and the proximity to green spaces or bodies of water create a conducive environment. Duplexes and triplexes built before the 1980s often have gaps in their foundations and around plumbing that pests exploit.

Our certified technicians regularly work in Villeray and are familiar with the specific characteristics of local buildings. This local knowledge allows us to tailor each service to the actual conditions of your home.


How do mice enter in your accommodation in winter

As soon as nighttime temperatures drop below 10°C in Villeray, mice actively seek warm shelter. The main entry points are:

  • Foundations: Cracks of even 6 mm are enough for a mouse to sneak inside.
  • Plumbing Unsealed openings around pipes under sinks and in bathrooms
  • Ventilation Ventilation grilles without screens or poorly protected dryer vents
  • Door thresholds The wear on the weatherstripping leaves a sufficient gap at floor level
  • Garage The ill-fitting garage door is the most common entry into single-family homes.

Preventive sealing before the cold arrives is the most effective and economical measure.


Measures of prevention effective

To protect your home in Villeray from mice, adopt these preventive measures recommended by our technicians:

Clogging: Seal all openings larger than 6 mm around plumbing, foundations, and window frames with steel wool and caulk.

✅ Food Storage: Store all food in airtight glass or rigid plastic containers

Waste Management: Take out the trash regularly and use containers with airtight lids

Humidity control: Repair leaks, ventilate bathrooms, and use a dehumidifier in the basement if necessary.

✅ Seasonal Inspection: Check entry points before each fall, especially after renovations.

People are asking also

Can mice climb walls?

Yes. Mice are excellent climbers and move easily through wall cavities, plumbing pipes, and spaces between floors. This is why nighttime noises in walls or ceilings are a classic sign of infestation.

How long does it take to fix a mouse problem?

With professional intervention including sealing off access points, allow 7 to 21 days. Without sealing, mice typically return within 2 to 4 weeks.
