Hello Karen & All, Although what I am about to say really does not pertain to the discussion many might find the story of interest. Last spring after answering a ad for bee equipment I appeared at the home of a beekeeper of over 25 years which had lost his bees to varroa and was selling out. I bought the items I was interested in but had a look at the other equipment for sale. When I looked at his deep brood chambers I was surprised to see the whole comb was drone but a very small oval in the center on all the frames and boxes. I asked him why all the drone? He replied the drone cells were his control for varroa. The varroa feeds on the drone and leaves the worker brood alone. A beekeeper *friend* in the south had shared his secret with him. Over half the box was drone comb. Although the boxes were in excellent shape, paint and the comb above average myself and friends were not interested because of the large amount of drone comb. After seven months of trying to sell the boxes they remain unsold. A normally fast moving item. Sincerely, Bob Harrison Odessa, Missouri Ps. Experiment with a few hives but not all your hives.
