One method reputed to work for finding difficult queens is to pin a dead
queen (preserved in the freezer) to the top bar of a frame in the brood box,
and close down for ten minutes. The theory is that the live queen will seek
out the supposed rival and can easily be found close to the dead queen.

I have had my doubts about this method, mainly about the survival of
pheremones on a long-dead queen. Ted's observations that the colony's queen
appears to be indifferent to his stored queens reinforces my doubts.

Has anyone had any personal experience, either way, of this method of
finding queens?
