Ant queens lay eggs. Ant colonies of some species of ants have only one queen while other species may have many queens. Worker ants forage for food for the colony, care for the queen and young, and defend the colony. Colonies may reproduce by swarming or budding. Ant nests commonly consist of underground tunnels and chambers.
Some species make mounds of earth or ant hills.
The queens stay in the nest and workers bring them food. It is the workers you may see in and around your structure. To control ants, pest control specialists must choose a treatment to target the infesting species. Ants must be treated differently, depending upon the species. When your property is invaded by ants, do not disturb them.
