The answer to 'what do fire ants look like' is that fire ants are small, reddish-brown insects that are typically 1/8 to 1/4 inch long. They have a rounded, segmented body with a defined head, thorax, and abdomen. Fire ants have six legs and two antennae, and their bodies are covered in fine hairs. They get their name from their fiery sting, which can be quite painful for humans and pets.
Fire ants are known for building large, dome-shaped mounds in the ground, often in sunny, open areas like lawns, gardens, and fields. When their nest is disturbed, large numbers of fire ants will quickly swarm out to defend their colony.
