@ahawahii,
I've read that "Crazy" Ants from the Gulf Coast area are known to move into electrical equipment boxes in sufficient numbers to short out some connections. This is the result of a colonizing behavior where they like to move into small enclosed spaces.
Apparently the Crazy ants are so invasive that they are pushing out the Fire Ants. Up in New Hampshire the Carpenter Ants will try to eat your house if you let them, but at least the little bitty Ants stay out in the field in their little mounds.
