Do ants fight with each other at times?

Question

Do ants sometimes fight with each other, on hind legs, battling with some of their arms, over pieces of food or other things? I thought for sure I saw some ants fighting, my kitchen is infested with ants right now in the sink, coming through the window. Let me know...

Answer 1

yeah sure i guess.

Answer 2

Ants may fight to protect their own nests or food storage from enemies or when they try to take over nests or seize food of not only other ant species, but also other colonies of the same species.  Ants are armed with the mandibles. Their mandibles are very strong, as indicated by their use in lifting large food objects. In some species, there is a caste of soldier ant, which has an especially large-sized head and mandibles.  In addition, some ant species, including Brachyponera chinensis, have a sting at the end of the abdomen, similar to bees and wasps, and use it when they fight. Other ant species eject a spray of a poison called formic acid from the end of their abdomen at their victims.  Ants fight fiercely and their battle may continue until they are torn to pieces and die.
