A friend just contacted me. They had an old elm cut down last Wed. When they got home from work, bees were everywhere. Apparently hived up in the tree. She felt bad and wanted me to try to save those still lingering. Husband says only half the swarming are there now, maybe they've settled back into their home. My plan is to carry a deep or two with drawn comb/honey and lure scent out to their place. Hopefully draw the bees into a better home. Will this work? Am I going to have to go in after the queen? I have no brood... lost my hives over winter... Do I need a one-way door at their entry to make them seek residence in my box? Any help would be appreciated.
