Put your trust in a local company that understands the realities of extermination in Montreal, and takes charge of your situation in a clear, structured and professional manner.

Montréal offers ideal conditions for infestations of rodents and harmful insects due to its harsh winters, old buildings, and underground networks. In several residential neighborhoods such as Rosemont, problems with mice or carpenter ants are common and often underestimated by homeowners.

A certified professional exterminator in Montreal has the local expertise needed to quickly identify the source of the problem and apply the appropriate treatments according to the type of nuisance, building structure and environmental standards in force. Unlike homemade solutions, certified treatments ensure long-lasting, safe and guaranteed results.

In areas like Plateau Mont-Royal, where older and attached housing promotes the rapid spread of pests from one building to another, it is essential to act quickly using proven and discreet methods.

When you call on an extermination expert, you also benefit from personalized support, precise evaluation and rapid turnaround - all essential factors in protecting your Montreal home or business.

Infestations of mouse in Montreal are common, especially in autumn and winter, when these rodents are looking for warmth and food. They infiltrate house walls, attics and floors through tiny openings - sometimes as small as a penny.

Common signs of infestation include scratching noises at night, droppings along walls or behind appliances, and persistent urine odors. Ignoring the problem can lead to major property damage, food contamination and respiratory health risks.

Our team of specialists uses professional methods that are safe for children and pets, including discreet traps, point-of-entry seals and certified products. Each intervention is tailored to your type of dwelling-whether it's a duplex, condo or commercial space.

Carpenter ants and pavement ants are among the most common pests in residential neighborhoods of Montreal, especially in spring and summer. Older homes, foundation cracks, and outdoor concrete structures create ideal conditions for these infestations.

Visit carpenter ants can seriously damage the structure of a building by burrowing into damp wood, while cobblestone ants colonize brick joints, low walls and entrances. These infestations are common in areas such as Villeray and Ahuntsic, where older buildings offer numerous points of entry.

At 911 Exterminateur, we use targeted, safe, and certified methods to eliminate colonies at the source. Our treatments include gel baits, physical barriers, and products approved by Health Canada, applied following a thorough site inspection.
