Jp, Yes they did tell me they had bees about three years ago in the same spot. She told me they were remodeling and found some old comb but could not figure how they were getting in. I guess now they know where they were getting in at.
One thing that is strange is we were not receiving any calls of swarms until the commercial beek brought in all his hive into the county. The lady from above said a day after he went by her house with a truck and tralier full of hives the bees arrived.
Well, that just means more bees for you!
BTW, great stuff is terrible for sealing exterior gaps. If gaps are larger than 1/4" I use a backing and caulk and seal.
