There 3 ways of communication for fire ants

1. Fire ants talk and communicate with other members of their colony with the help of signals and pheromones. The pheromones are chemical stuff excreted by animals to influence the behavior of others members of the society. As you are aware, the fire ants spend great part of their time in direct contact with the ground. Whenever it is moving in search of food or some other purpose, it leaves a trail along the ground. The other fires ants pick up this trail and follow. While returning home, the trail is reinforced, bringing other fire ants, till the food is used up. Thereafter, the trail is not reinforced and gradually disappears. This is a fine way of communication in fire ants.

2. Some more examples of how fire ants talk is when the hungry fire ants are seen stroking or tapping one another with their antennae asking for food. They also exchange food with each using mouth to mouth exchange. These fire ant “kisses” are a way of fire ants communication for sharing nutrition and chemicals.

3. Another way of how fire ants talk is by making sound. By rubbing the joint between its waist and abdomen it is able to produce a squeaky sound, which is often a cry for help. The other fire ants on hearing this sound come running for help.
Fireants also two compound eyes, having many lenses, which help them, see things as broken up. Therefore they are able to detect any movement better than shape. This is really helpful as they live underground in dark areas with no light. But using sight is not the common means of communication in fire ants.
