Every pest. One team.

Carpenter ants are one of the main structural threats to wood-framed homes in Quebec. They do not transmit disease, but they tunnel through damp wood, weakening framing over time. On the South Shore we also see pharaoh ants (honey-colored, problematic in kitchens) and pavement ants (under slabs, in cracks). KZ Extermination identifies the species, locates the parent colony, then eliminates the queen — without that, the problem keeps coming back.

Cockroaches are one of the most stressful pests to find in a home or apartment. The German cockroach (most common in Montreal and South Shore apartment buildings) reproduces very quickly — a single female can produce 30,000 descendants in a year. They carry bacteria (E. coli, salmonella), worsen asthma, and contaminate food. An infestation cannot be solved with hardware-store products. KZ Extermination uses a multi-visit protocol with professional gel baits and growth regulators to eliminate adults, juveniles and eggs.

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.

The Norway rat (brown rat or sewer rat) has become a growing problem in Greater Montreal since 2020. Bigger, smarter and more dangerous than the mouse, it digs tunnels under foundations, contaminates food storage areas, and transmits leptospirosis, salmonella and rarely hantavirus. A rat infestation is an emergency — their reproduction and trap-shyness make this a pest only a professional protocol can eliminate.

Wasp nests become dangerous from July-August in Quebec, especially for allergic individuals. On the South Shore we mainly find the common wasp (yellow and black), the German wasp (more aggressive), and the bald-faced hornet (large hanging nest, very defensive). Attempting DIY removal at the wrong time can result in dozens of stings in seconds. KZ Extermination intervenes in full equipment, neutralizes the nest at source, then removes it safely.

Bed bugs are not a hygiene problem — they affect 5-star hotels as much as modest housing. They travel in luggage, second-hand furniture, backpacks. Once installed, they hide in mattress seams, bed frame cracks, baseboards — and emerge at night to feed on human blood. Bites cause itchy red welts, but the worst impact is psychological: insomnia, anxiety, social isolation. KZ Extermination uses a multi-visit protocol to break the full cycle (egg → adult) that lasts 6 to 8 weeks.

The boxelder bug is the typical fall invasion on the South Shore — especially in zones with mature maple trees like Saint-Lambert, Boucherville and Old Longueuil. They seek warm overwintering sites and often find the sunny exterior of homes. Though they don't bite or damage structure, they enter by the hundreds through walls, windows and attics — re-emerging in spring. Treatment combines exterior eradication and physical exclusion.
