>Do some people actually reverse brood boxes every couple of weeks as a swarm controle? I've never heard that one before.
http://www.beekeeper.org/mar2003.htm"YOU simply REVERSE
the position of the boxes. by removing the empty lower brood box and place it
on top of the highest brood box, so the queen now has empty laying space above her.
This should be started in late winter or very early spring, about 75 days before a good
nectar flow commences; and depending on whether you are using 2 or 3 brood boxes, the fecundity
of your queen, initial bee population, and other variables, you might have to
reverse 2, 3, or even 4 times during these 75 days. There is a danger in REVERSING, and
that is splitting the brood (i.e., one group of brood left in the TOP of a frame while there
is another group of brood left in the BOTTOM of a different frame. I STRONGLY suggest
you read my old PINK PAGES or the Hive & Honey Bee about HOW TO REVERSE.)" --George Imirie
