What Are Crazy Ants?

Crazy ants are winning the turf war with fire ants thanks to a built-in defense mechanism.
Crazy ants can save themselves from the venom of fire ants by grooming themselves with an antidote they secrete from a special gland. Instead of a stinger, they have a fire ant anti-venom gland! The substance is formic acid, and it's use is two-fold: the same antidote that they use to nullify venom on themselves is used as a chemical weapon against competitors. With this built-in dual-purpose chemical, it seems crazy ants are unbeatable.
