Swarms of them come out in force to bite or sting their enemies. Many kinds of ants have powerful jaws or can inject painful chemicals through on their back ends. Some even shoot out burning, irritating chemicals such as from their rear ends, as these ants are doing. While digging tunnels, ants turn over tons of to let in air, water, and nutrients. This helps plants grow.
