There are two main modes: chemical and tactile communication. The huge majority of communication among ant species happens chemically, either when workers mark surfaces with certain pheromones or by spraying them (for example in case of danger spraying the scent spreads the message more quickly). Smells also play a huge role to determine wether a fellow ant is friend or foe.
