The Plateau's iconic triplexes, high tenant turnover, and dense urban fabric make it one of Montreal's most pest-affected neighbourhoods. Blackline Pest Control specializes in multi-unit building treatments for bed bugs, cockroaches, and rodents — in English and French.
Plateau landlords: Quebec law requires landlords to maintain pest-free units. We provide documentation for the Tribunal administratif du logement (TAL).
Plateau-Mont-Royal is one of Montreal's most densely populated and culturally vibrant neighbourhoods — and one of its most pest-challenged. The neighbourhood's iconic triplexes and duplexes, many built between 1900 and 1940, are architectural gems with a significant pest vulnerability: shared walls, shared plumbing, and shared electrical conduits that allow bed bugs, cockroaches, and mice to spread freely between units.
The Plateau's high tenant turnover — driven by its popularity with students, young professionals, and artists — means infested furniture and belongings move in and out of buildings constantly. A single infested mattress left on the curb can trigger a building-wide bed bug outbreak within weeks. The neighbourhood's active used furniture market and thrift store culture amplifies this risk significantly.
The Plateau's dense restaurant scene along Avenue du Mont-Royal and Rue Saint-Denis creates cockroach pressure that spills into neighbouring residential buildings. Blackline Pest Control works with Plateau landlords, property managers, and tenants to implement coordinated building-wide treatment programs that address infestations at the source rather than unit by unit.
Treating one unit while adjacent units remain infested is a waste of money. We coordinate building-wide treatments that actually work.
We inspect all units and common areas to map the full extent of the infestation before recommending treatment.
We coordinate with landlords and all tenants to schedule simultaneous treatment of all affected units.
All units treated on the same day to prevent pests from migrating to untreated areas during treatment.
We provide complete documentation for the Tribunal administratif du logement (TAL) if required.

"As a landlord with three triplexes on the Plateau, bed bugs are my biggest nightmare. Blackline has become my go-to — they respond fast, treat all units simultaneously, and the 100-day guarantee means I'm not paying for re-treatments. They understand the Plateau's building stock perfectly."
"Found bed bugs in my apartment on Rue Saint-Viateur. Called Blackline at 9pm and they were there the next morning. Treated my unit and coordinated with my landlord for the adjacent units. Professional, fast, and they explained everything in French. Highly recommend."
"We had a cockroach problem in our restaurant kitchen on Avenue du Mont-Royal. Blackline came after hours, treated everything, and provided full MAPAQ documentation. No disruption to service. They've been our pest control partner for two years now."
Here are the pests most active right now in Montreal and surrounding areas — and what's coming next.

The Plateau's high tenant turnover, dense triplex buildings with shared walls, and active used furniture culture create ideal conditions for bed bug spread. A single infested unit can spread to an entire building through shared electrical conduits and plumbing chases.
Yes. We specialize in coordinated building-wide treatments for Plateau triplexes and duplexes. We treat all units simultaneously to prevent re-infestation from untreated units, and coordinate with landlords and tenants to minimize disruption.
We can reach Plateau-Mont-Royal within 2–4 hours for emergencies. Same-day standard bookings are available 7 days a week. We also serve neighbouring Mile-End, Rosemont, and Villeray.
Both tenants and landlords can contact us directly. In Quebec, landlords are legally responsible for maintaining pest-free rental units under the Civil Code. We can work with either party and provide documentation for both.
Bed bugs are the most reported pest in Plateau-Mont-Royal, followed by cockroaches (particularly German cockroaches in buildings near restaurants on Mont-Royal and Saint-Denis), mice, and carpenter ants in older wood-frame buildings.
