Thank you Mr Van. I hope this works. I will post the video where I found this. Langford says the SHB have a hard shell and can not walk down the pipe and simply go inside because of its hard, unbendable shell. They can not pivot and bend into the turn and will simply fall to the ground. "I have watched them do this," he said.
I am wondering; If we were to sharpen, the edge of the pvc fitting, making it even thinner at the edge, shouldn't it make it even harder for the SHB to enter? This should up our odds of keeping them out if so. I am also wondering if we were to place the entrance fitting at a 90 instead of a forty-five, this should also up the odds since SHB can not fly straight up? This should not hamper our bees from entering?
Mr Van, once we have trained our bees to use this passage, could we open the main entrance and place screen for ventilation where the main entrance is designed? Wouldn't this also work as a good anti-robbing entrance in that accord? Yet affording not entrance for either bee nor SHB in the screen area? I am thinking it will.
Robbers should naturally go to the (open) of the screen missing the true entrance? Along with running the SHB nuts! lol
Thank you for posting this.
