So I got a call for bees in a wall (I know, I said I wasn't going to do that this year... so much for that), and there's two different hives in the same wall. The wall is stucko over cinder-block so you know they're down in the cinder-blocks where I can't get to them to cut them out. So anyway, one hive I can get a bait hive set up next to it so that the bees can just walk on over to it... the other hive is near the roof (dark patch on wall near roof just a bit too far to the right of the top of the stairs to reach from the stairs). So I can get to that one, via hanging over the edge of the building from the roof, but there's nothing to anchor a bait hive to there. I went ahead and put a funnel on it, but have no way right now to get the bees other than going back every few days with a bee-vac to vacuum up the bees that cluster there. Do you have any suggestions on ways to get them?
