This is a rather technical matter, and requires understanding of bees, timing, and observation. Here is some of what is required to understand the problem: Bees prefer to store honey in dark comb and raise brood in new comb. Bees prefer (in the high latitudes at least) to have the brood running up and down the hive, not so much across the hive. Young queens are more adventurous about where they will lay. Old queens are less likely to cross wood or honey to find a spot to lay or have as large a brood area at some times of the year. After the spring, brood nest expansion will end (usually) and brood rearing will tend to take place mostly in combs which have had brood previously during that season assuming the brood nest is undisturbed. This is especially true with older queens and some breeds. In a strong flow bees will move honey storage into any cavity in the hive when they run out of space and will even build comb under the hive floor on occasion or fill jars placed over holes in a cover (it may have to be covered to be dark). Bees tend not to want to walk over much capped honey to begin storing honey in a new space -- especially in a slow flow. Once bees start to work a strong flow, they will tend to keep going until they run entirely out of space. Once bees go into a new space and begin work there excluders are no barrier. If they are permitted enough space under an excluder to store significant honey and raise lots of brood, they may refuse to go through it; hence excluders are really tricky in three standard brood nest colonies. Small populations do not tend to expand through excluders unless crowded by them. Swarming is easily stimulated early in the season and almost never happens as the season tapers off. Bees not properly supered early enough (before the need is pressing) will swarm. Using the above tendencies, a wise beekeeper can use excluders to get the right performance from his/her bees. Perhaps someone will add to this list. The goal is not only to get a good crop, but also to get it with a minimum of fuss and damage to the bees. Since Alberta has gone to wintering from package production, and beekeepers have had to learn something about bees, commercial beekeepers have slowly gone over to excluders. Very few that I know are not using them to some extent. In areas with predictable heavy flows, the excluder is less essential. In other areas, it makes preparation for wintering (in two brood chambers) much simpler. W.
