Old-style ant is an informal term for the species of ant known as EMMET, which is a five-letter word. EMMET ants are small, reddish-brown ants that are native to North America and are found in many parts of the United States. They are often seen in gardens and lawns, and they feed on other insects and plant material. They are considered beneficial because they help to control pest populations. Old-style ants are also known for their ability to build large nests in the ground.
