Fire ants are smaller than most people imagine. One characteristic of this ant species most people don't want to experience is the painful sting and the resulting pustule. Brood are immature fire ants.
Brood is the eggs, larvae and pupae.
Fire ant queens have lived for as long as seven years, but on average live approximately three years. Worker ants' life span is much shorter. In general, fire ant workers live four to six weeks. In the mound fire ants have an extensive tunneling system. The tunnels are constructed to improve air movement throughout the colony.
