German yellowjackets. They are bigger and faster than the kind that mess in your kid's sand box. They make big nasty hives out of wood chewing. Last year we got honey bees getting into our house in a bad window trim. The yellow jackets moved in on them. We made life uncomfortable for them and they moved a half block east to another house. They still have a problem with them. Years ago a farmer that was a shirttail relation, decided on Labor Day, that it was a good time to fix his off the rails machine shed door. The yellow jackets had built a nest behind it. He died before he got to his house. Another one about that same time, a farmer wanted to disc the corner of his field near his farm place where the family garden was planted, so he backed into position and bumped a stack of wooden fence poles. He was found dead on his tractor going in circles in his field. German yellow jackets have a way of targeting an aggressor, so the entire fleet knows what to attack. From what I saw last year, I know that i am not fast enough to outrun them. A hornet flies like an ultralight bi-plane, a German yellow jacket flies like an x15 fighter jet.
