...If I may add: And through good management (most of the time) one doesn't even need a queen excluder (which is called a "honey excluder" by some beekeepers :) ). A beekeeper who has time to invest on his/her hives can manipulate the frames (that are in the boxes) in a way to "encourage" the queen stay away from the honey boxes. Also there are other matters, such as swarm protection etc. that can be done thanks to modern hive design. For example, I can give my colonies more room (adding more boxes with empty frames) and/or split a colony by taking some brood frames (and nurse bees) and putting them in a brand new hive (which lets the queenless nurse bees to raise a new queen). Beekeeping (I can only speak as a hobbyist) is lots of fun... and some stress :). Highly recommended!
