Carpenter Ant: Identification and Dangers

Carpenter ants (Camponotus spp.) are social insects known for digging tunnels in wood to build their nests. They do not consume wood, but can cause major structural damage, particularly in damp or water-damaged areas.

Habitat and behavior

Carpenter ants live in forests, but often invade homes, burrowing into damp wood in frames, walls, or windows. Active mainly at night, they search for nectar, insects, or food scraps.

Hazards and damage

Their activity can go unnoticed, weakening wooden structures over several years. An advanced infestation can seriously damage roof structures and require costly repairs.
