Infesting home and buildings in search of food and water, black house ants are especially attracted to sweet foods but also eat honeydew which is excreted from sap-sucking insects, as a result they are known to tent to aphids and bugs on domestic plants. Black house ants can be aggressive towards other species of ant if disturbed. They are omnivorous, feeding on insects and worms, as well as vegetation, such as small seeds.

Black house ants usually nest under stones or dry logs. The species can commonly be found in gardens.

Black House Ants live in coexistent relationships with other common suburban ants, like the Green-headed ant.
