First, the good news: Crazy ants don't sting. They do sometimes bite, but the pain is mild, and it fades quickly. Even better, they drive out their stinging cousins, fire ants, which have been tormenting Texans for decades. Now, the bad news: When entomologists say "crazy," they mean it.

"When you talk to folks who live in the invaded areas, they tell you they want their fire ants back," Ed LeBrun, an invasive species researcher at the University of Texas, told the Los Angeles Times. "Fire ants are in many ways very polite. They live in your yard. They form mounds and stay there, and they only interact with you if you step on their mound."
Crazy ants on the other hand? They swarm madly over anything and everything, whether it's outside your home or not. With no natural predators, their colonies grow to 100 times the size of those of the typical ant colony. Homeowners have been known to sweep them out of houses with a broom. Also, crazy ants have developed an expensive taste for electronics. Computer mice are one example, but also transformers and electrical switches, where the carcasses of large numbers of shocked ants can cause short circuits and clog switching mechanisms.More »
