That sure is a huge nest Mona! :new_shocked:
I have to say that this was the worst summer I have ever seen for wasps and hornets. We could not walk out the back door of our house without them flying all round us and trying to land on us. It usually doesn't bother me, but because there were so many, I didn't dare move if they landed on me for fear I would bump one and anger it. And the poor hummingbirds were even chased away from the feeder time and time again by huge wasps.
We usually just leave them alone too, but this summer they were just too numerous. Next year I am going to get some of those glass traps that you put the sugar water in and hang up.
