Wasps building nests — remove early before colonies grow
Most pest control companies use the same off-the-shelf treatment for every job. We don't. Montreal's housing stock, climate, and pest pressures are different from anywhere else in Canada. That's why Blackline Pest Control was built specifically to serve Greater Montreal — not as a franchise, not as a national chain, but as a team of specialists who know these buildings, these neighbourhoods, and these pests better than anyone.
Over 60% of Montreal's residential buildings are plexes — triplex, duplex, and quadruplex units sharing walls and floors. A pest problem in one unit almost always spreads to neighbours. Quebec's Civil Code places shared responsibility on landlords and tenants. Treating one unit without treating adjacent units rarely works.
Montreal winters regularly hit -20°C or colder. Mice, rats, and cockroaches are driven inside by mid-October and stay until spring. Fall is the most important time to seal entry points and inspect your home — waiting until you see pests means they've already established a colony.
Under Quebec's Civil Code, landlords must maintain pest-free dwellings. If a landlord refuses to act, tenants can apply to the Tribunal administratif du logement (TAL). Blackline works with both landlords and tenants and provides documentation for TAL proceedings when needed.
Food service businesses in Quebec are inspected by MAPAQ (Ministère de l'Agriculture). A single cockroach sighting during inspection can trigger a temporary closure. Blackline provides MAPAQ-compliant pest control reports accepted by inspectors across Quebec.
Understanding which pest you're dealing with is the first step to solving the problem. Here's what you need to know about the four most common pests in Montreal homes.
Bed bugs can survive up to 12 months without feeding. One female lays 200–500 eggs in a lifetime. Early detection is key — a small infestation becomes a major one within 6–8 weeks.
Quick Tip
Check mattress seams and bed frames weekly. Inspect hotel room beds before unpacking.
German cockroaches are the most common species in Montreal apartments. They multiply fast — one pair becomes 10,000 offspring in a year. They spread bacteria like Salmonella and E. coli on every surface they touch.
Quick Tip
Seal gaps around pipes. Never leave food uncovered overnight. Fix leaky taps — cockroaches need water more than food.
A mouse can enter your home through a hole the size of a dime (6mm). Mice gnaw on wires — a leading cause of house fires. Montreal's old housing stock has many hidden entry points that most homeowners never find.
Quick Tip
Look for droppings along walls and in cupboards. Check under stoves and behind fridges. Seal gaps with steel wool before caulking.
Carpenter ants are the number one structural pest in Quebec. They tunnel through damp or damaged wood — not to eat it, but to build nests. A large carpenter ant colony can weaken beams and joists over several years.
Quick Tip
Fix water damage and leaks first — carpenter ants only colonize wood that is already softened by moisture. Trim tree branches touching your roof.
Prevention is always cheaper than treatment. These eight steps stop most pest problems before they start. They're simple, fast, and cost almost nothing. Do them once a year — especially in September before the cold drives pests indoors.
Seal all gaps around pipes, cables, and conduits where they enter walls — mice can squeeze through anything wider than 6mm.
Fix dripping taps and leaking pipes immediately. Cockroaches and carpenter ants are attracted to moisture more than food.
Store garbage in sealed containers. Move compost bins away from the building exterior. Empty indoor bins every night.
Trim tree branches that touch or overhang your roof. They act as highways for squirrels, mice, and carpenter ants.
Inspect used furniture, clothing, and luggage before bringing them inside. Bed bugs travel on fabric and hide in seams.
Store firewood at least 6 metres from your home. Firewood piles are nesting sites for mice, carpenter ants, and termites.
Check basement walls and window wells for cracks every spring. Freeze-thaw cycles in Montreal create new entry points each year.
Schedule a professional inspection every fall — before pests move in for winter. Prevention costs far less than treatment.
