I've got a leak in my house that I cannot find. Wasps continue to get in and threaten me, my wife, dog, and cat. I found a nest last year, but this year they are back. We see them flying around everywhere and then they somehow make it into our house. It is a daily chore to kill any of those guys flying around. I have no idea how they are getting in and no idea where the nest(s) are. Any ideas?
