Houston has got a problem...
Sounds like a two-parter...
DALLAS — 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 ants _ formally known as "paratrenicha species near pubens" _ have spread to five Houston-area counties since they were first spotted in Texas in 2002.
The newly recognized species is believed to have arrived in a cargo shipment through the port of Houston. Scientists are not sure exactly where the ants came from, but their cousins, commonly called crazy ants, are found in the Southeast and the Caribbean.
"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.
(...) 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. They have been spotted at NASA's Johnson Space Center and close to Hobby Airport, though they haven't caused any major problems there yet.
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.
"The population built up so high that typical ant controls simply did no good," said Jason Meyers, an A&M doctoral student who is writing his dissertation on the one-eighth-inch-long ant.
It's not enough just to kill the queen. Experts say each colony has multiple queens that have to be taken out.
