Carpenter ants in Montreal
We locate the colony in damp wood and treat it at the source.
The carpenter ant is the largest ant found in Quebec homes. It doesn't eat wood: it digs galleries in it, especially in damp or damaged wood around windows, porches, roofs and basements.
Seeing a few large black ants inside in spring can signal a colony in the structure or close to the house. The earlier it's found, the simpler the treatment.
Signs to watch for
Large black ants inside, especially in spring
Small piles of sawdust near frames, beams or baseboards
Winged ants coming out of a wall or ceiling
Faint rustling in a wall at night
Damp or rotten wood near the house
