How Did I Get Carpenter Ants?

These insects usually build their nests in damp, sound or decaying wood. Homes with moisture issues caused by leaks are prime targets for carpenter ants. The pests will also use tree branches that overhang roofs as a bridge, accessing buildings to find a way inside. Unsealed openings around utility pipes and wires are common entry points.

How Serious Are Carpenter Ants?

Cosmetic & Structural Damage
When carpenter ants build nests, they dig out tunnels in wood, weakening it from the inside. A long-term infestation with multiple colonies in a home often means serious structural damage and unsightly cosmetic damage.
