Ants exterminator in Longueuil
Professional ants elimination in Longueuil. Certified IPM method, experienced technician, fast response across the South Shore.
Local context: Longueuil
Why ants are common in Longueuil
Longueuil combines older neighborhoods (Vieux-Longueuil with its pre-1950 buildings, typical foundation cracks) and newer sectors (Saint-Hubert, Le Moyne, Greenfield Park). This mix means KZ technicians encounter the full pest spectrum: carpenter ants in wood joists, basement mice in winter, boxelder bugs on south façades near Michel-Chartrand park.
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.
How to detect them
Signs of ants infestation in Longueuil
- Small piles of sawdust (frass) near baseboards or window frames

Our intervention
Professional method in Longueuil
Our approach has three steps: (1) full interior and exterior inspection to locate the parent colony and satellites, (2) targeted treatment with professional baits that workers carry back to the queen, and (3) exterior perimeter treatment to prevent re-infestation. A 30-day follow-up can be scheduled on request. Our products are low-toxicity and Health Canada approved.
