According to the Associated Press, Texas has been invaded by a breed of ants that is attracted to electrical equipment. The ants have already ruined pumps at sewage pumping stations, computers, and at least one gas meter and have caused several fire alarms to malfunction.

The hairy, reddish-brown insects are known as “crazy rasberry ants.” They are called crazy because they wander erratically and “fast, fast, fast,” according to one resident who has had to cope with them. The rasberry comes from Tom Rasberry, an exterminator who battled the ants early on.

The ants are believed to have arrived in a cargo shipment through Houston and have spread to at least five Houston-area counties since the first sighting in Texas in 2002.

They are immune to over-the-counter ant killers, and stronger pesticides are ineffective because the ants apparently pile up their dead to use as a bridge to cross safely over surfaces treated with the chemicals.
