Computers, burglar alarm systems, gas and electricity meters, iPods, telephone exchanges - all are considered food by the flea-sized ants, for reasons that have left scientists baffled.
Having ruined pumps at a sewage facility, the ants are now marching towards Nasa's Johnson Space Centre and William P. Hobby airport, Houston, putting state officials in a panic. "They're itty-bitty things, and they're just running everywhere," said Patsy Morphew, a resident of Pearland, on the Gulf Coast.
She spends hours sweeping them off her patio and scooping them out of her pool by the cupful. "There's just thousands and thousands of them. If you've seen a car racing, that's how they are. They're going fast, fast, fast. They're crazy."
"At this point it would be nearly impossible to eradicate the ants because they are so widely dispersed," said Roger Gold, a Texas A&M University entomologist. He added that the only upside to the invasion was that the crazy rasberry ants ate fire ants, which sting humans during the long, hot Texas summers.
Pest control specialists say that they are inundated with calls from homes and businesses now that the warm, humid season has begun, with literally billions of the ants wreaking havoc across the state. Worse, the ants refuse to die when sprayed with over-the-counter poison. Even killing the queen of a colony doesn't do any good, because each colony has multiple queens.
