I am interested in any shortcuts or efficiencies to the task of locating an
unmarked queen for fall or spring requeening, short of laboriously examining
each brood chamber panel, hoping I haven't missed her, setting the panel
aside and going on to the next.  The Florida State University newsletter
suggested the following; do you know of any other techniques?
 
        - Take a brood panel from an adjoining hive first shaking or brushing
it clean of bees from that hive; then make room for and insert it into the
hive whose queen you want to replace.  Within 5 minutes the queen from that
hive will be on the panel you introduced, drawn by the foreign pheremones to
do battle with the supposed intruder queen.
