The oldest ants are generally the foragers. Brood, the non-mobile stage of fire ants, are not entirely without means of communication or behavior. Although little research has been conducted on this life stage observations that have been made are quite insightful.

There are several behavioral characteristics that identify this insect pest. One of the characteristics of RIFA is the type of mound it constructs.
