According to a Georgia Power Company Engineer: ants love the "vibrations" let off by electrical wiring. In my area we have those transformer boxes that are about a cubic yard size mounted on the ground. Fire ants will actually get into them, build a mound that will short them out and "BANG", electricity goes out to maybe six houses at a time. I have actually seen one of those fully functional boxes when opened there was no room left for electrical anything, just full of good old south GA. red clay and ants. The cable TV boxes and telephone company boxes are not exempt either, these little buggers do not discriminate.
