Ant's and Bee's seem to love electricity. It's almost like the eat it. I have had more problems with outside circuits and equipment due to ant's, bee,s, wasp's than any other problem. The dead one's short out contacts, the live one's get in the way, and can be painfull. My guy's used to always carry some kind of flying insect killer with them when ever they went out to the substation because even before they could fix anything it was kill them first, then clean contacts replace wire's because insulation was gone. Found mice inside the switchgear from time to time. What's really strange is they seem to like the 115KV better than the 110.
Edit, I gotta get that spell checker.
