Like straight out of a horror movie.
DALLAS (AP) — In what sounds like a really low-budget horror film, voracious swarming ants that apparently arrived in Texas aboard a cargo ship are invading homes and yards across the Houston area, shorting out electrical boxes and messing up computers.
The hairy, reddish-brown creatures are known as "crazy rasberry ants" — crazy, because they wander erratically instead of marching in regimented lines, and "rasberry" after Tom Rasberry, an exterminator who did battle against them early on.
"They're itty-bitty things about the size of fleas, and they're just running everywhere," said Patsy Morphew of Pearland, who is constantly 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."
The ants — formally known as "paratrenicha species near pubens" — have spread to five Houston-area counties since they were first spotted in Texas in 2002.
"At this point, it would be nearly impossible to eradicate the ant because it is so widely dispersed," said Roger Gold, a Texas A&M University entomologist.
...But the ants also like to suck the sweet juices from plants, feed on such beneficial insects as ladybugs, and eat the hatchlings of a small, endangered type of grouse known as the Attwater prairie chicken.
They also bite humans, though not with a stinger like fire ants.
Worse, they, like some other species of ants, are attracted to electrical equipment, for reasons that are not well understood by scientists.
They have ruined pumps at sewage pumping stations, fouled computers and at least one homeowner's gas meter, and caused fire alarms to malfunction.
....
Exterminators say calls from frustrated homeowners and businesses are increasing because the ants — which are starting to emerge by the billions with the onset of the warm, humid season — appear to be resistant to over-the-counter ant killers.
....
And when you do kill these ants, the survivors turn it to their advantage: They pile up the dead, sometimes using them as a bridge to cross safely over surfaces treated with pesticide.
