The army raid will seek out and capture mostly spiders and insects, such as caterpillars, millipedes, cockroaches, or katydids. The army will attack other ant colonies and wasp nests. Vertebrates with any speed are usually able to escape these arthropod predators, but when given the opportunity the ants will pursue frogs, lizards and snakes.

The grossest thing I have seen so far. Luckily it was at a friend's house. And dead.
