Well, I posted a Craigslist ad for the bees and actually got several enthusiastic replies (one read, "I need your bees now"). Unfortunately at three or four this afternoon every single one had vanished. It was pretty amazing though, since when I went out this morning it was like a cloud of bees, then a solid writhing swarm, and now they are all gone.
So I guess what I've learned is I need a bee hive that wild bees can move in to. They were very un-agressive, and man did they move through my garden fast.
