How big is this hive? If it's one deep I recommend you freeze the frames to kill the wax moths and larva then simply drop in on top of a full strength hive. They will clean up the dead, repair the combs and adjust the honey such that they can use it for the upcoming winter. If it's a two deep hive do this with two full strength hives. Don't let the moths finish up what they started, it's a waste of perfectly good resourses.
