I just got a call from the folks trying to tear down that barn where we removed 8 colonies. They still cant get in there because of bee's. He called and described to me what sounded like a swarm now. A ball of bees 2ft by about 3 ft long just one the side of a wall. Anyway, I think I may need to go spray down the cavaties where we did the cutouts. I know its attracting more bees. What can I get locally to do this with. Can't wait on a mannlake order.
