Well who would mess with an army of ants?
Well there are a few predators.Ants have a few animals that can and will pick on them. For instance if out by themselves other ants may gobble down the single ant for a quick lunch. that is why it is always best to tracel in groups.
Other ant predators are the ant lion catching ( Formica japonica ) These guys have some huge pinchers and love ants as a tasty meal. He will quickly suck the juices out of the animal after he falls into his trap.
Bears love to destroy the ant colonies and can quickly devour 1000's of these critters in no time flat.
