Local context: Montréal
Why boxelder bugs 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.
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.

Signs of boxelder bugs infestation in Montréal
- Hundreds of black bugs with red markings on sunny walls
