Houston has been hit with a computer bug like no other: a swarm of ants that are eating through electronics. The "Crazy Raspberry Ants" are believed to have arrived in Texas aboard a cargo ship, and are causing widespread mayhem. For some unknown reason they are attracted to electrical equipment, which is causing problems for residents in the Deep South. The ants have destroyed PCs in homes and offices, ruined pumps at a sewage treatment plant and even taken a fancy to homeowners' gas meters, according to reports from the Associated Press. "If you open a computer, you would find a cluster of ants on the motherboard and all over," said Tom Raspberry, the owner of Budget Pest Control and the man the ants have been named after.
