Red imported fire ant

Found in open areas such as lawns, pastures, and fields, often building large earthen mounds, and sometimes invading buildings.

Omnivorous, feeding on dead animals, insects, seeds, and sweet secretions from other insects.

Highly aggressive, highly social insects that live in large colonies and attack en masse when their mound is disturbed.

Risks include painful venomous stings that cause burning and pustules, and potential allergic reactions; benefits include preying on agricultural pest insects.
