Carpenter ants are among the most destructive insects for wooden structures in Ahuntsic. Unlike termites, which eat wood, carpenter ants tunnel through it to build their galleries—and the damage can go unnoticed for years.
In short: Fine sawdust (frass) near baseboards, door frames, or beams is the most reliable sign of carpenter ants. A professional diagnosis allows for an assessment of the extent of structural damage before it worsens.
Ahuntsic: why the ants are frequent here
The Ahuntsic neighborhood has characteristics that favor the presence of ants. Housing density, the age of buildings, and proximity to green spaces or waterways create a conducive environment. Duplexes and triplexes built before the 1980s often have gaps in their foundations and around plumbing that pests exploit.
Our certified technicians regularly work in Ahuntsic and know the specificities of local buildings. This local knowledge allows us to adapt each intervention to the actual conditions of your home.

Do carpenter ants eat wood?
No, unlike termites. They tunnel into damp wood to build their galleries and nests. The fine sawdust (frass) you find is excavated, undigested wood.
How to differentiate carpenter ants and pavement ants?
Carpenter ants are large (6-13 mm), black, and leave sawdust. Pavement ants are small (3-4 mm), dark brown, and nest outside in concrete cracks.
