Carpenter Ants

Description:

Medium to large workers, 1/4-inch to 1/2-inch. Thorax evenly rounded. Colonies have workers that are not all the same size (polymorphism). Black carpenter ants are most common species in Nebraska.

Habitat:

In their natural habitat, carpenter ants aid in the decomposition of dead, decaying trees. They normally nest in logs, stumps, and hollow trees. However, the large, dark-colored workers often invade homes in search of food.
