I would like to correct what i wrote yesterday. Someone wrote me a question that pointed out how unclear i had been.

I wrote:
"Here's a trick i learned from an experienced beekeeper over here.
He keeps Carnolians, like myself, and obviously has had to find a
way to tame their swarming tendencies. When you open up a colony
and find that they are building queen cells, move all boxes over
and put an empty box on the bottom board. Then put the cover on the
new box, with the entrance facing in the other direction. On top of
it, stack all the boxes and put on a new cover (which could be a
simple and cheap piece of plywood or styrofoam). Now, the older
bees will fly out the new entrance, gather nectar and pollen, and
then return in the way they're used to. The bottom box will be
filled with the older bees (and honey!) and the colony on top will
be all younger bees. With the colony out of balance this way, they
will not swarm."

Now, the box that goes in the bottom (the new box) should of course have frames. The frames should also have drawn comb. Foundation will not do, since these older bees that return through the original entrance will not build comb.

Sorry 'bout that.
