Pest ID Guide

Carpenter Ants

Carpenter ants

Identification

Larger ants, often black or reddish-black, 1/4 to 1/2 inch long, with a smooth, evenly rounded thorax.

Habitat

Nest in damp or decaying wood, including tree stumps and fence posts, and moisture-damaged framing inside a home.

Why They're A Risk

Excavate wood to build nests, weakening structural beams and framing over time if left untreated.

Signs To Watch For

Piles of fine sawdust-like material (frass) below wood surfaces, and faint rustling sounds inside walls.
