Montreal's #1 rated pest control company. We serve all boroughs — from downtown condos to suburban homes — with certified technicians, eco-friendly treatments, and a 100-day guarantee.
Montreal's unique combination of aging housing stock, extreme seasonal temperature swings, and one of Canada's highest urban densities creates ideal conditions for pest infestations year-round. The city's iconic triplexes and duplexes — many built before 1960 — have accumulated decades of cracks, gaps, and deteriorating mortar that provide easy entry points for rodents, cockroaches, and ants.
The city's active tourism industry and high tenant turnover in student-heavy neighbourhoods like Côte-des-Neiges and the Plateau make bed bug transmission a persistent challenge. Montreal consistently ranks among the top three Canadian cities for bed bug reports. Meanwhile, the harsh winters drive mice and rats indoors from October through April, making rodent exclusion a year-round necessity.
Blackline Pest Control serves all 19 Montreal boroughs with certified technicians who understand the specific pest pressures of each neighbourhood — from the dense apartment buildings of Rosemont to the heritage homes of Outremont.

Yes. We use Health Canada-approved products with low mammalian toxicity, specifically selected for use in residential settings with children and pets. For chemical treatments, a re-entry period of 2–4 hours is required. Gel bait treatments require no re-entry period. We always explain safety precautions before treatment.
Under Article 1854 of the Civil Code of Quebec, landlords are legally responsible for maintaining rental units in good habitable condition — which includes being free of pest infestations. Landlords must pay for professional pest control regardless of how the infestation started. Notify your landlord in writing and give them a reasonable deadline to act.
The most common pests in Montreal are bed bugs (particularly in dense apartment neighbourhoods like the Plateau and Côte-des-Neiges), German cockroaches (in apartment buildings and restaurants), mice and rats (year-round, peaking in fall), carpenter ants (spring through fall), and wasps and hornets (June through October). Montreal's extreme climate and dense housing stock make it one of Canada's most pest-active cities.
