You can't fool a WASP....
 

........For the wits here who might get the pun :o). Anyhow, the brown paper
bag may or may not work. There was no wasps' nest on the rafters of my
tool-shed this year, but there was one being very quietly constructed under
a bike basket in there, about two feet off the ground. I had been happily
walking by it each time I entered the shed. Not an easy one to dispose of,
but the unfortunate deed is done.......Pinetree
