Our services in the
neighborhoods of the South Shore
Longueuil’s commercial districts, particularly Taschereau Boulevard, are home to a concentration of restaurants, grocery stores, and food shops that are prone to infestations of cockroaches, mice, and flies. Adjacent apartment buildings and condominiums are also at risk for bed bugs.
Brossard’s high residential density, with its many condominiums and high-rises, facilitates the spread of bed bugs, cockroaches, and pharaoh ants between units. Our protocols are tailored to multi-unit buildings.
The proximity of Mount Saint-Bruno and its natural areas makes this area a favorite habitat for carpenter ants, raccoons, and skunks. Homes on the outskirts of the national park regularly experience wildlife intrusions.
The mixed-use neighborhoods of Saint-Lambert, with their mix of single-family homes and small businesses, are vulnerable to mice in the fall and wasps in the summer. Old stone and brick buildings easily harbor bats and carpenter ants.

South Shore Pest Control FAQ
My upstairs neighbor has mice, and now I have them in my condo. Who is responsible—the homeowners' association or each individual owner?
In a condominium building, liability depends on the source of the infestation. If rodents are moving through shared walls or shared ducts, the homeowners’ association is generally responsible for treating the common areas. MW Extermination works with homeowners’ associations on the South Shore to coordinate building-wide treatments.
I manage a rental building in Longueuil, and a tenant has reported bed bugs. What is the protocol for the entire building?
The protocol for an entire building includes an inspection of all units adjacent to the one reported, a treatment plan coordinated with the tenants, and documented follow-up. MW Extermination offers a turnkey service for property managers on the South Shore, including the intervention reports required by the Administrative Housing Tribunal.
My store on Taschereau Boulevard has cockroaches in the back room. Can you treat the infestation without closing the store?
Yes. Depending on the extent of the infestation and the type of business, we tailor our approach to minimize disruption to your operations. Gel treatments (baits) generally do not require the business to close. We conduct treatments early in the morning or outside of peak hours, depending on your situation.
We're moving into a new place in Brossard—are you conducting preventive bed bug inspections before the move?
Absolutely. A preventive inspection before moving in is an excellent practice, especially in properties with high tenant turnover. Our technicians inspect every nook and cranny, including mattresses, baseboards, and built-in furniture. If any signs of damage are detected, we take immediate action. It’s better to know before you bring in your furniture.
I have a damp basement in Saint-Lambert that attracts woodlice and spiders. Is this a pest control issue or a moisture problem?
Both. Woodlice and spiders are attracted by moisture and the presence of insects, which they feed on. MW Extermination treats the pests present, but also recommends addressing the source of moisture (ventilation, drainage, vapor barriers) to prevent the problem from recurring. Without fixing the moisture issue, the problem will inevitably return.
