I need some advice. I got a phone call this morning, about doing a cutout in a home. The is empty and this lady is fixing to move into it, but there some bees that taken up residence in a wall. The out side of the house is rock, and you can see their entrance where they come and go. We cut the Sheetrock out in three or four spots, and couldn't find anything. In the attic by the fireplace we moved a little mortar and there a couple bees there. The bees are somewhere in that fireplace, so it's impossible to get to them with busting down the chimney. I told the lady she could call an exterminator if she was in a hurry to get them out, or if she could wait for me to get back in a few days I would try to bait them out of their little spot. She chose to wait on me. My biggest challenge is its an hour drive to her house. From what the neighbors say it is a huge hive, and has been there 4-5 years. The opening is 8'2" off of the ground so I am going to put a bait box up there on a stand. Any advice you folks have for me would be greatly appreciated. I hear you put lemon oil in the bait box, but beyond that I don't know else to do. help.
