Fire ants are omnivorous insects that eat many different kinds of animal and plant material. They prey on small animals like mice, ground dwelling amphibians and reptiles and eat ground-nesting birds, live insects and dead insects. Fire ants will also eat the carcasses of large dead animals and will even attempt to bring down large animals that are injured or sick.
Besides feeding on live and dead animals, fire ants actively search for seeds and fruit and will eat the inner bark of trees and shrubs. Fire ants also consume the honeydew produced from scale insects, aphids and other homopterous insects. Adult fire ants must first have any solid food particles converted to liquids by older larvae in the colony before they can consume it themselves.
