Pavement ants can be found throughout the Eastern United States and in California. They nest under rocks, in cracks in pavement, and along the edges of curbing. Pavement ants measure from 1/10th to 1/8th of an inch in length. Their appearance ranges in color from light to very dark brown. Their legs and antennae are much paler.
A pavement ant colony is started by a single queen that lays the eggs and tends the brood. The brood then develops into worker ants. As they mature, the tending of the nest is take over by workers. The workers shift the location of the nest as moisture and temperature fluctuates. When workers forage for food for the queen and her young, they can enter homes and become a nuisance.
