:idea: ive had this idea for a while now. lets say for whatever emergency comes up that your not able to clean your hive of queen cells during the swarm season for a two week period. or you wish to get rid of a few drones some evening when they leave the hive for their daily flight. or, say you have italian bee's and your fellow beekeeper down the road has cocasian bee's (or vice versa) and you dont want one of his queens geting into one of your hives. would it make sence to use a queen excluder type of contraption over the entrance? ive never seen such a thing, but it kinda makes sence, or does it?
