Hello All I am of the opinion that finding and marking queens is an utter waste of time. OK, call it making a virtue of a necessity but so be it!. I cannot find queens even if the queen is known to be on the frame I am holding. If we really think about it, we do not need to find the queen, we need to know which box she is in or which box she is not in. So all we have to do is to sieve the bees through a pristine queen excluder and the objective is achieved. At least it worked for me last year. All I have to do now is to convince the Senior Certificate examiners that this is a valid answer to finding queens. Sincerely Tom Barrett 49 South Park, Foxrock Dublin 18 Ireland #
