leechmann,from what i read and what other people tried to find out is that no one no what make them land,but they do.they have peolpe that say it doesn't work and its a myth.well i saw it work at but2 when iddee did it and it worked for me.i had to do it with that same hive again when i let the queen out of the queen catcher.that evening they swarmed and would not land after 10 min. so i got my bucket and started to beat on it and they landed in just a short time .myth or not i saw it work, ......schawee
