She is afraid of bees, and said she saw Carpenter bees under our pool deck. She won't go under it to look. They scrape small holes for a nest for a single egg upward into wood. They are quite harmless and the small hole does very little damage.It can be caulked full at the end of the season. Here is the lie. I told her I didn't see any nests, even though there was one. I hate killing creatures that are not harmful.
