Facing a cockroach infestation in Montreal-North, most residents react instinctively—and do precisely the wrong thing. These well-intentioned mistakes often worsen the situation instead of resolving it.
In short: Over-the-counter products, insufficient cleaning, and delaying reporting the problem are the most common mistakes when dealing with cockroaches. This article explains why they don't work and what to do instead.
Montreal North: why the cockroaches are frequent here
The Montreal-North borough has characteristics that favor the presence of cockroaches. Population density, the age of buildings, and proximity to green spaces or waterways create a conducive environment. Apartment buildings constructed before the 1980s often have gaps in their foundations and around plumbing that pests exploit.
Our certified technicians regularly work in Montreal-North and are familiar with the specific characteristics of local buildings. This local knowledge allows us to adapt each intervention to the actual conditions of your home.
The errors the most common ones facing cockroaches
After years of intervention in Montreal North, our technicians have identified the most frequent errors:
- Use over-the-counter products: aerosol bombs, sticky traps, and ultrasonic repellents — these products move the problem without eliminating it. Worse, they can disperse the colony and make the infestation harder to treat.
- Wait for «it to pass»: A cockroach infestation never resolves itself. Every day of delay allows the population to grow.
- Clean without treating: Impeccable housing reduces food sources but doesn't eliminate cockroaches already in the walls or structures.
- Processing a single dwelling in a building: Cockroaches migrate to apartments not treated through shared vents.
Measures of prevention effective
To protect your home in Montreal-North from cockroaches, adopt these preventive measures recommended by our technicians:
Clogging: Seal all openings larger than 6 mm around plumbing, foundations, and window frames with steel wool and caulk.
✅ Food Storage: Store all food in airtight glass or rigid plastic containers
Waste Management: Take out the trash regularly and use containers with airtight lids
Humidity control: Repair leaks, ventilate bathrooms, and use a dehumidifier in the basement if necessary.
✅ Seasonal Inspection: Check entry points before each fall, especially after renovations.

Can cockroaches fly?
Some species have wings but rarely fly. In Quebec, the German cockroach (the most common in homes) does not fly. It moves quickly on the floor and walls.
Is a single cockroach a sign of an infestation?
Not necessarily, but it's a warning sign. If you see one during the day, there are probably dozens hidden — cockroaches are nocturnal and only come out during the day when the nest is overcrowded.
