Sean, The cold killed them. That is why I waited until the middle of the=20 winter to open the wall. I actually discovered the nest in August. I=20 noticed that the surface of the wall was wavy. When I touched the wall=20 it moved and it was obvious that there was no support behind the paper=20 and the paint. Thanks, rich! P.S. The soap water is a good idea for a general trap. rich!
