I don't like killing anything=20 but I have to when the hornets become more than just a nuisance. One time I had a infestation in a wall. I waited until winter=20 before I opened the wall up. It was scary and cool at the same time.=20 They had eaten the inside paper and all of the wallboard up to but not=20 including the outer layer of paper that was inside the house and=20 painted. The nest was 6 inches thick, 14 inches wide, and 6 feet high.=20 It had to contain 100s of thousands of hornets if not millions.=20 Fortunately they hadn't broken through that last layer of paper and=20 gained access to the house. Ouch, rich!
