Pavement Ants are fairly small, with workers about 1/8th inch in length. They will frequently invade houses in search of just about any food, especially meats and greases, creating trails of up to 30 feet. They usually enter houses from cracks in the slabs. Once inside, Pavement Ants often travel underneath the carpet. They may infest the upper stories. of commercial buildings. Outdoors they will be found around pet bowls, but will also go after insects, seeds, and honeydew. Once they find food, the workers swarm all over it. They have a stinger, but will rarely use it.
