This same thing happened to my very strongest hive this summer. I kept adding supers because they were growing so fast. Well I believe at least for me, I had way to many supers on that hive at a time when they were getting weaker for some reason.
I never lost my queen as I found her with the marking. But following the advice on this forum, I removed the frames that were destroyed by the wax moths and I froze any other frames that they got on, but I was able to save. I reduced the hive down to 2 medium supers and they were then able to defend themselves from the wax moths and believe it or not, this hive built up again really, really strong.
If you squeeze the remaining bees down to one super, they can keep the moths away and slowly build up again. Just for future reference.
