I use bee repel in the early fall to help take off honey. I don't use queen excluders (honey excluders, I call them ... but don't follow that red herring) in the summer, but I would like to start using them in mid August. I use double deeps for a brood nest and mediums for honey and would like to put the excluders in in mid-August so any brood above the excluder has time to emerge before I do my final round of taking off honey. My question concerns the use of Bee Repel. Let's say I put a fume board on in mid-August and took of the top super which was just honey, and let's say the super below had honey but also brood. Could I put the fume board above this super and reliably expect the queen to be driven down? I know the nurse bees don't want to abandon brood, even though there is a cloud of Bee Repel around them, but does that apply to the queen as well? It would sure make inserting queen excluders an easier task if one could use the Bee Repel and trust that the queen had been driven down without having to check. Using a queen excluder and Bee Repel this way would help me get all my hives reduced to a double brood nest in time for winter feeding and wrapping. As it is, I usually wind up wintering about 10% to 15% of my hivesin a double brood nest with a medium on top which had been used as a "collector" for brood from other hives in the yard that had brood in the medium honey supers. Any advice welcome.
