Ants have elbowed antennae, a thread-like waist with one or two bumps. Unmated reproductives have wings, the front wings are larger than the hind wings. Workers ants are wingless. Ants are social insects. Colonies are usually established by a queen. Workers feed the queen, care for the brood and defend the nest. Workers travel along well-marked trails between the nest and food.
Follow good sanitary and exclusion practices. Exploit worker caste by using baits. Find foragers and place bait near foraging trail. Workers then bring the poisoned bait back to the nest where it is distributed among all members of the colony. If ants are foraging indoors from an outdoor nest, exclude ants by sealing entry points such as window sills and door steps, or spray entry points into the structure.
