Well, I tried the vibrator on the exterior of the column for about one hour. Although the bees seemed a little confused, there was no grand exodus from the hive. I'll send Jay Leno a copy of the video. One never knows when you might be on the edge of a great discovery. Oh well.
I did set up a one way cone and it is working well. Many are going into the box I put next to the cone . The box has some old brood comb, honey, lemongrass oil and a frame of brood and bees.
After the owner saw the setup and I described how long it might take, we agreed upon opening up the column from inside the building (kind of like a big shed). I should have very good access to the entire colony which may be up to seven feet tall.
Thanks for all the input. After reading about other members' experiences, I'm really looking forward to this. I'll take pictures and post if I am able.
