Shake the bees out into a empty brood box above a Queen excluder, but she may be slim and fit through the Queen exluder ???, .. another option take five frames out and shake the bees of into the hive.. leave the other six frames in there with a space inbetween each pair leave for 10 mins... the Queen does not like light and will go inbetwen the three pairs of frames, if you are fortunate enough not to have a laying worker colony try a mated Queen in a cage one the top bars and see how the bees react, if they ball the cage and you cant get them of you may have a Virgin Queen in there if they ball the cage and you can move them from the cage easily you might be Queen - , good luck and is a shame you are not closer as i have a clear eye for spotting the elusive Devil Queens.. lol .
Feel free the oracles of the forum to shoot me down in flames but his is the procedure in my head to find a Queen.
