Last week, I had an inspection and I did not see the wasp nest above the back door. Unfortunately for me the wasp were a little more observant and I was stung on my arm. It hit so hard that it left a little blood. Luckily I really don't have much of a reaction to them, but you just never know.
Down here in the south we deal mostly with what I have nicked named "Nuclear Wasp"! The Red or Mahogany wasps pack quite a wallop when they sting. They are also very aggressive and will attack many feet from their nest. This is a close up picture of a Red Wasp nest that I found a while back at a home.
Anyway, just be sure that you have that wasp spray in your tool bag. You never know when you will need it. I really like the one that shoots out like foam. It stick to everything it hits.
