UPDATE:
Will I went by this afternoon. I opened a hole lower in the wall. The owner said that he had not seen any bees coming out in the pass couple days. So I filled the cavity with smoke to see if any were left. Nothing came out so I took the cone off and removed the brick that they coming out from around. It was a large swarm. no comb. The week I put it on we had a hard freeze. I foundd about a half pail full of dead bees. Darn. so I button up the hive and sealed everything. I got the hive home and set it up and then opened it. I found three frames of bees and 2 new queen cells with one starting to open.

I will leave them a loan for the next 2 weeks. Will I was up the ladder I got two more calls. one at a house with the bees in a interior wall. Oh what fun that will be. I have it setup for this comming week. then got another call bees in the bathroom wall of a old workshop.This one on the ground floor and they are remodeling. so demo not a problem. should be a fun one. I'l take photo's of both to post.
sorry I may not be there for Bud's but I will be keeping it in mind during my birthday removals.
