Bed Bug Exterminator in Montreal
Punaises de lit destroying your sleep? Blackline Pest Control delivers proven heat treatment and chemical extermination with a 100-day guarantee — so you can rest easy again.
Why Bed Bugs Are a Serious Problem in Montreal
Montreal consistently ranks among the top cities in Canada for bed bug infestations. The city's aging housing stock, high-density apartment buildings, and active tourism industry create ideal conditions for punaises de lit to spread rapidly between units. A single infested piece of used furniture or a suitcase brought back from travel can trigger a building-wide outbreak within weeks.
Bed bugs are not a sign of poor hygiene — they are opportunistic hitchhikers that feed exclusively on human blood. They hide in mattress seams, behind baseboards, inside electrical outlets, and within furniture joints during the day, emerging at night to feed. Their bites cause intense itching, sleep deprivation, anxiety, and in some cases secondary skin infections from scratching.
DIY solutions — sprays, powders, mattress covers — almost never eliminate an infestation. Bed bugs are resistant to many over-the-counter pesticides, and their eggs are nearly impossible to reach without professional equipment. Only certified extermination Montréal professionals using heat treatment or targeted chemical protocols can guarantee complete elimination.
Blackline Pest Control uses a combination of thermal remediation (heating rooms to 50–60°C) and Health Canada-approved residual treatments to eliminate every life stage — eggs, nymphs, and adults — in a single visit. Our 100-day guarantee means if bed bugs return, we come back at no charge.
How We Treat Bed Bugs in Montreal
A systematic, science-backed approach that eliminates every life stage — guaranteed.
Thorough Inspection
Our certified technician conducts a room-by-room inspection using flashlights and detection tools to map the full extent of the infestation, identify harborage sites, and determine the appropriate treatment protocol.
Heat Treatment Setup
Industrial heaters raise the room temperature to 50–60°C — lethal to all bed bug life stages including eggs. Heat penetrates mattresses, furniture, walls, and clothing that chemical sprays cannot reach.
Residual Chemical Application
We apply Health Canada-approved, eco-friendly residual insecticides to baseboards, electrical outlets, furniture joints, and wall voids. These products remain active for weeks, eliminating any survivors and preventing re-infestation.
Follow-Up & Guarantee
We schedule a follow-up inspection 2 weeks after treatment. If any bed bug activity is detected within 100 days, we return for a free re-treatment. Your peace of mind is our commitment.

Signs of Bed Bugs in Your Montreal Home or Business
The sooner you identify an infestation, the easier and less expensive it is to treat. Know what to look for.
Rust-Coloured Stains on Bedding
Small reddish-brown spots on your sheets, pillowcases, or mattress seams are crushed bed bug remains or their excrement — one of the earliest and most reliable indicators.
Dark Ink-Like Spots on Mattress Seams
Bed bug fecal matter appears as tiny dark dots along mattress seams, box spring edges, and headboard crevices. These spots bleed into fabric like a felt-tip marker.
Visible Eggs and Shed Skins
Bed bugs shed their exoskeletons 5 times as they mature. Finding translucent, hollow shells in crevices, behind baseboards, or inside electrical outlets confirms an active infestation.
Itchy Welts in a Line or Cluster
Bed bug bites appear as red, itchy welts often arranged in a line or zigzag pattern on exposed skin — arms, neck, shoulders, and legs. Unlike mosquito bites, they appear in groups.
Sweet Musty Odour
A large bed bug infestation produces a distinctive sweet, musty smell similar to coriander or almonds. If your bedroom has an unexplained odour, it warrants immediate inspection.
Live Bugs in Seams and Crevices
Adult bed bugs are apple-seed sized, flat, and reddish-brown. Check mattress seams, behind headboards, inside nightstand drawers, and along baseboards with a flashlight.
Neighbour Reports in Your Building
In Montreal apartment buildings, bed bugs spread through shared walls, electrical conduits, and plumbing. If a neighbour has reported bed bugs, your unit is at elevated risk.

Frequently Asked Questions About Bed Bug Extermination in Montreal
How long does bed bug heat treatment take?
A full heat treatment for bed bugs typically takes 6 to 8 hours depending on the size of the property. The entire space is heated to 50–60°C, which kills all life stages of bed bugs including eggs.
Do I need to throw away my mattress after a bed bug infestation?
No — in most cases you do not need to discard your mattress. Our heat treatment kills bed bugs inside mattresses, box springs, and furniture. We may recommend a mattress encasement after treatment as a precaution.
How did I get bed bugs in my Montreal apartment?
Bed bugs spread through travel, used furniture, clothing, and shared walls in apartment buildings. Montreal's dense housing stock and high tenant turnover make it one of Canada's most affected cities.
How many treatments are needed to eliminate bed bugs?
Heat treatment is typically a single-session solution. Chemical treatments may require 2–3 visits spaced 2 weeks apart. Our 100-day guarantee covers free re-treatment if bed bugs return.
Are bed bug treatments safe for children and pets?
Yes. We use Health Canada-approved products and eco-friendly methods. Children and pets should vacate during treatment and can return once the space has been ventilated, typically 4 hours after chemical treatment.
What is the cost of bed bug extermination in Montreal?
Bed bug treatment in Montreal starts at $350 for a studio or one-bedroom unit. Larger properties, multi-unit buildings, and severe infestations may cost more. We provide a free inspection and quote before any work begins.
