Camponotus modoc or western carpenter ant is a black carpenter ant with dark red legs.

[citation needed] It occurs in Western North America, where it makes nests in dead wood, including dead logs in the forests, as well as human houses.

[1][2] Carpenter ants will damage homes by nesting in them.

They will dig out tunnels in wood to expand their living spaces which can lead to structural damage.

The infestation in the home usually is a satellite colony, with the main one within a hundred yards or more in a stump or other decayed wood.
