Two ants dominate
in Quebec
In Quebec, we mostly see two kinds of ants: the carpenter ant and the field ant (or pavement ant). The carpenter ant is easy to recognize: it is black and large. It is the biggest of the common ants in Quebec. Its playground? Damp wood, outside or inside the house. The field ant, on the other hand, is brown or black and smaller. It likes sand, cracks in the house, paving stones and asphalt.
Carpenter ants
Carpenter ants threaten the structure of your buildings by digging into the wood. When there’s an infestation, you need to act fast. After a precise inspection, we identify the infested areas and build an action plan to eliminate the threat for good.
Red ants
Workers moving regularly on the surface, small mounds of soil or sand in thin grass or in the driveway, workers swarming food or garbage bins, aphid farming on some plants, eggs or pupae under rocks.
Pharaoh ants
Pharaoh ants must be eliminated with protein and sugar baits placed near the nesting areas. Avoid aerosol or powder insecticides: under stress, the colonies split up and spread, which makes the problem even harder to contain.

How do you recognize a carpenter ant?
The carpenter ant is easy to recognize: it is black and large. It is the biggest of the common ants in Quebec: its workers measure 6 to 13 mm. Its playground? Damp wood, outside or inside the house. To learn the warning signs, watch our video (in French): carpenter ants, the signs you should never ignore.
How do you recognize red ants?
You may notice workers moving regularly on the surface, small mounds of soil or sand in thin grass or in the driveway, and workers swarming food or garbage bins. Aphid farming on some plants and workers, eggs or pupae under rocks also point to a colony nearby.
How do you get rid of pharaoh ants?
For a truly effective treatment, pharaoh ants must be eliminated with protein and sugar baits placed as close as possible to the nesting areas. It’s very important to avoid aerosol or powder insecticides, because they can stress the colony. Under stress, colonies split up and spread, which makes the problem even harder to contain.
Are your treatments safe for my family and my pets?
Yes. Using modern methods and eco-friendly solutions, we carry out a complete extermination with no risk to your family or your pets.
Why do ants keep coming back?
Ants spend the winter sheltered in the ground or inside walls, then become active again as soon as it warms up. Workers follow the scent trails left by their colony back to the same food: crumbs, sugar, pet food. Spraying the ants you can see doesn’t reach the nest or the queen, so the colony simply sends new workers. That’s why we locate the nest and treat the colony itself. On your side, a few habits make a big difference: food in airtight containers, counters wiped every day and cracks sealed around the foundation.
How much does treatment cost?
The price depends on the species and the size of the infestation. The final price is set on site, after the inspection. Call us at 1·888·582·2191.
