What Are Crazy Ants?

Crazy ants are an invasive species.
Originally from South America, the tawny crazy ant — also called the raspberry crazy ant — showed up in the southern United States in 2002 or perhaps earlier. Their presence is more than just an annoyance. Because they feed on small insects and arthropods, they're gobbling up food that other species like birds and reptiles rely on. Their presence will trickle up the food chain with currently unknown ramifications — and there doesn’t seem to be much that can stop them.
