Facing an ant infestation on the Plateau Mount Royal, Most residents react instinctively and do the exact opposite of what they should. These well-intentioned mistakes often worsen the situation instead of resolving it.
In short: Over-the-counter products, insufficient cleaning, and delaying a report are the most common mistakes when dealing with ants. This article explains why they don't work and what to do instead.
Plateau Mont-Royal: Why are the ants are frequent here
The Plateau-Mont-Royal neighborhood has characteristics that favor the presence of ants. Housing density, building age, and proximity to green spaces or waterways create a conducive environment. Plexes built before the 1980s often have gaps in their foundations and around plumbing that pests exploit.
Our certified technicians regularly work in Plateau Mont-Royal and are familiar with the specific characteristics of local buildings. This local knowledge allows us to tailor each intervention to the actual conditions of your home.
The errors the most common ant problems
After years of interventions in Plateau Mont-Royal, our technicians have identified the most common 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»: An ant infestation never resolves itself. Every day of delay allows the population to grow.
- Clean without treating: Impeccless housing reduces food sources, but does not eliminate ants already established in walls or structures.
- Processing a single dwelling in a building: Ants migrate to untreated dwellings through shared conduits.
