The pyramid ants are so named due to a single, conical projection on the top of the thorax. They are single node ants which nest primarily in the soil, either in open areas where a circular crater forms around the nest opening, as well as under rocks or logs or other debris on the ground. They do not often invade structures, but may do so occasionally while searching for food. Outdoors they feed on living or dead insects, and are very fond of honeydew from plant feeding insects. Colonies are small, with only a few thousand workers.
Control of most ants includes correction of the attractions that drew them to a property, including harborage sites, food sources, and moisture conditions. Elimination of insects that provide protein or honeydew sources reduces ant foraging in an area, very important for this species, and cleanup of unnecessary debris or objects on the soil that provide harborage eliminates nesting. Ant bait products in granular, liquid, or gel formulations can be effective, and carbohydrate baits may be preferred.
