I will put the old hive boxes on a new hive one at a time and drive all the bees out of the old hive bodies and into the new hive using the fume board. I will re-assemble the old hive in the old place. The new hive will have the old queen and the nurse bees. The old hive will have all the fly-backs and the capped and open brood to raise a new queen. snved, did you try your suggested method? Anyone see a problem with this? Only thing I saw above is the concern of this being harsh on brood. I plan on using the almond scented stuff and not the horrible smelling stuff. There will be 3-4 mediums that make up the new hive for the bees to escape to when fuming them out of the old hive box. I will cover the bottom entrance while doing this (have screened bottom boards).
