Even though they are common here in Wisconsin, pavement ants are actually an invasive species of ants that were brought over from Europe during early settlement. These small ants roughly ⅛-in long are very similar in appearance to little black ants. They are typically dark brown to black in color. Pavement ants are often found nesting under pavement, hence their name.
Pavement ants are the ants that you typically see on your driveway or walkways with mini mounds of sand and soil. These small mounds of dirt help keep the nest cool during the hot summer months. Like most ants, they enjoy a wide range of food, especially honeydew from aphids. Other items would include dead insects, seeds, nuts, and human foods. Pavement ants can sting in defensive, but it causes nothing more than a mild discomfort to humans. These ants will actually host epic battles in the summer months as they try to expand their colonies into enemy territories.
