So his hive has dwindled down to the point he has a bad case of moths. He had them in a double deep and went through and cleaned it out so now it fits in a single deep. Almost no brood and has no larva or eggs. What does he need to do? Freeze the drawn frames and then let them clean them out I'd guess. He's looking at buying a single deep hive off Craigslist if it looks ok. Guy says it has 7 frames of brood. Should he combine the new hive and the old one or move a frame of brood from the new hive and let the moth hive requeen themselves?
