Have come into some older bee hives deeps with no frames, wondering if they would make a good swarm trap? My plan is to put a soild bottom on a, center cut inch and half entry hole and on the inside hardware cloth to keep birds out. Does the top cover need to be same size as hive body? or can you use a hive cover off some old hives instead? I do have old comb and LGO, any input or comments would be great.
