I added this post to one that was already going but then wondered if it would be seen so I guess I'll start a new one.
Here is our dilemma with Yellow Jackets. See picture here http://jenny-jennywhocaniturnto.blogspot.com/2009/09/six-word-saturday.html
We keep sealing up openings that we find because they keep finding or making more. I would like to try the Sevin method but now we have all these holes sealed up with caulking. You can hear some pretty major clicking from outside. We don't have any YJ's inside yet and I really don't want to discover them working their way in.
Should I work the caulking out of one of the original entrances and puff the Sevin into that? What do you recommend?
