The Allegheny Mound Ant
Allegheny mound ants (Formica exsectoides) are native to the Atlantic area of North America. They are field ants that can build impressive mounds in open areas. They are common in the Midwest and Northeast. Allegheny mound ants are known to build some of the largest ant mounds in the world.
These ants are aggressive, and will definitely bite even if slightly disturbed. They rarely enter homes, but having an ant mound close to human living quarters can be risky.
