A friend called to ask if I could take a look at "a whole mess of bees" in a tree on her property. I stopped by this morning to investigate, and found a very nice colony behind a tennis-ball sized hole in a large cherry tree. The entrance is about six feet from the ground - take a look:

Does anybody know of any technique that might work to extract this colony? (Cutting down the tree isn't an option). Wire coning will only extract the workers, so I don't know what good that would do us.

I'm really hoping to save this colony from destruction -- any advice would be appreciated.

Thanks!
