There's good evidence that not only fire ants, but other ant species are attracted to electrical equipment.

"Once ants in a switching mechanism bridge the gap between an open switch, they are shocked and electrocuted. The shocked ants release communication chemicals (pheromones) or other signals that attract other worker ants. The result is that switching unit can become tightly packed with the bodies of dead worker ants, causing a failure of the mechanism."

Whether this mechanism becomes operative in electrical sockets (regardless of whether they're in active use) I have no idea; but I've heard invasion/colonization by such means described by other homeowners. And while there are plenty of entry points in a home that are more convenient for fire ants, I don't recall having a problem with them coming in via cracks around windows and doors (for instance).

A "hard freeze" is a descriptive term generally used to describe temps that fall below freezing for at least a few hours, sufficient to kill tender vegetation. Most of Texas (even the Gulf Coast region where I lived) gets hard freezes every winter; it's not unusual for DFW to get into the teens a few times.

The range of the fire ant includes most of Texas (the panhandle is apparently still too cold for them) and much of the South, including places that get a goodly amount of cold weather and freezes (such as a large chunk of Tennessee).
