The pests we treat most in Montreal

Mice

Mouse season really starts in October: once nights drop below freezing, mice move into the warmth of the walls. A mouse fits through a 6 mm gap. In a duplex or triplex, the voids between floors and the shared walls connect the units, so treating one apartment often just moves the problem next door. Control means inspection, secured bait stations and, above all, sealing the way in.

Rats

The rat of Montreal's back lanes is the Norway rat. It burrows under sheds, slabs and composters, and travels through the sewers. Burrows along the foundation or greasy rub marks at the base of walls are telltale signs. It is controlled outdoors with locked bait stations, and by closing off access to the building.

Cockroaches

Almost every cockroach found in a Montreal apartment is a German cockroach. A single egg case holds around thirty eggs; they live near warmth and moisture (kitchens, bathrooms) and move between units through ducts and baseboards. Store-bought sprays scatter them without dealing with the colony; effective treatment relies on well-placed gel baits and follow-up visits. Our guide to German cockroaches in Montreal housing covers the preparation.

Bed bugs

On July 1st, tens of thousands of Quebec households move on the same day. Mattresses and couches left on the sidewalk carry bed bugs from one neighbourhood to the next. They have nothing to do with how clean a home is. A treatment that works takes serious preparation (bedding and clothes washed, then dried for at least 30 minutes on the highest heat), an inspection of neighbouring rooms, and a second visit for the eggs that hatch after the first. See also how to keep them from coming back.

Carpenter ants

Montreal has a lot of exposed wood: balconies, outdoor staircases, galleries. Carpenter ants don't eat wood; they hollow it out where it is damp or damaged. Large black ants indoors in spring often point to a nest in the structure, not just in the yard.

Wasps

From July to September, nests hide under balconies, in eaves and in hedges. A nest by a door or a play area is worth treating rather than living with.

For homes and apartments

For a one-off problem, a targeted treatment. To stop thinking about it, our Bronze, Gold and Platinum home protection plans combine perimeter treatments, an audit, indoor treatments and an annual follow-up.
