MONTRÉAL, QC - Pest control professionals across Montréal are reporting a marked increase in rodent activity inside residential and multi-unit buildings during the winter season, particularly in older urban neighborhoods where structural vulnerabilities are more common.

According to industry observations, mice and other small rodents tend to migrate indoors during colder months in search of warmth, food, and shelter. Cracks in foundations, aging brickwork, shared utility lines, and poorly sealed entry points in duplexes and triplexes create ideal access routes for rodents.

“In many cases, infestations are not caused by poor hygiene but rather by the design and age of the buildings themselves,” said a pest control specialist familiar with Montréal’s residential housing stock. “Once temperatures drop, rodents exploit even the smallest openings to gain access.”

Rodent presence inside buildings can pose multiple risks, including contamination of food preparation areas, damage to insulation and electrical wiring, and the spread of bacteria through droppings and urine. Specialists note that early detection is critical, as rodent populations can expand rapidly if left unaddressed.

Urban pest control professionals also report that early warning signs such as scratching noises inside walls, droppings near food storage areas, and damaged insulation are often overlooked until infestations become more established. Preventive measures such as sealing exterior gaps, maintaining proper waste storage, and monitoring basements and wall voids are commonly recommended to reduce indoor rodent activity.

In multi-unit residential buildings, coordinated prevention efforts between occupants and property managers are often necessary due to shared structural elements that allow rodents to move between units undetected.
