We had the same problem a few years ago. My wife was so upset about it, she was ready to sell. After reading all of the post here and trying all of the above mentioned, plus some, the only thing that worked was finding where they were getting in and filling it with STEEL WOOL. It takes time to find were they are getting in, but if you stick with it you will finally succed. Try this, have someone get in the comparment during the day, close the compartment door, have them move around as much as they can, to look for any light coming through. If that doesn't work, turn your compartment lights on at night. Get under the coach and look for any light leaking through. If that don't work, which this it didn't for me, just get under the thing and start looking. Maybe do a third of the underside a day. Here is where mine was, the compartment where the water line and dump valves were located. There was a broken weld, that left a small hole. I put steel wool in there and haven't had a problem since. Good luck. PS. I was thinking, if someone had the right marketing knowledge they could sell that powder that glows in the dark. When you put a black light on it after spreading it around the coach, the little creatures walk in it and there you go. This would maybe give you a clue where they are getting in.
