About 2 months ago we had a swarm of bees take up residence in the gable of our church, aprrox. 40' off the ground. They are inside the boxing. We've tried caulking their entry points but they just find another entry. So far we're having no luck. It wouldn't be a problem except they are coming into the sanctuary, which tends to make church a little more exciting than usual at times. Is there anyway to lure them out? Ideas?
