Carpenter ants are large, black or reddish-brown insects belonging to the Camponotus genus. They typically range from 1/4 to 1 inch in length, with a smooth, rounded thorax and a distinctively segmented body. Unlike termites, carpenter ants have a narrow waist and prominent mandibles, which they use for cutting through wood.

These ants are known for their nesting habits, often creating colonies in decayed or damp wood. They excavate tunnels and galleries within the wood, which can lead to structural damage in homes and trees. Carpenter ants are social insects, living in colonies that can number from a few hundred to several thousand individuals, featuring a queen, workers, and occasional winged reproductives.

Carpenter ants are primarily nocturnal and are attracted to sugary substances, making them common household pests. They can be identified by their distinctive trails and the sounds of rustling in wooden structures. While they do not eat wood like termites, their tunneling can compromise the integrity of wooden structures over time. Effective control involves locating and eliminating nests and addressing moisture issues to prevent infestations.
