Mice exterminator in Montréal
Professional mice elimination in Montréal. Certified IPM method, experienced technician, fast response across the South Shore.
Local context: Montréal
Why mice are common in Montréal
Montreal presents Quebec's widest range of pest situations: century-old Plateau duplexes and triplexes, modern downtown condos, single-family homes in residential neighborhoods (Ahuntsic, Saint-Léonard, Anjou). Density creates specific challenges: cockroaches in apartment buildings, bed bugs in tourist zones, growing rat issues in several boroughs. KZ Extermination serves all island boroughs.
An adult mouse only needs a pencil-width hole to enter. When the cold arrives in October, thousands of mice try to get into Greater Montreal homes — basements, crawl spaces, garages, attics. A single female can have 5 to 10 litters per year. They contaminate food, gnaw electrical wires (a fire cause), and their droppings can transmit viruses like hantavirus. Our intervention eliminates the existing population, then we precisely identify the entry points and hand you a detailed plan you (or your contractor) can seal — without that, the problem returns next fall.
How to detect them
Signs of mice infestation in Montréal
- Black rice-grain droppings in drawers, under sink, behind stove
- Scratching or running sounds in walls and ceiling at night
- Gnawed food packaging, unusual crumbs
- Strong urine odor in closed spaces
- Holes or gnawing on wood, plastic or wires
Our intervention
Professional method in Montréal
Our two-phase intervention: phase 1 — elimination via secured bait stations (child- and pet-proof) and mechanical traps at strategic points for 14 to 21 days. Phase 2 — exclusion diagnosis: full exterior inspection, precise identification of entry points (often <1 cm), with a written materials recommendation (steel wool, mortar, specialized caulking) you can do yourself or have your contractor handle. A 60-day follow-up can be scheduled on request.
Prevention
