Wasp Nests

My tumbledown shed at the allotment had a wasps nest in last year. I just let them get on with it not knowing where exactly the nest was. They were coming and going through a gap at top of door. In the autumn after all activity had ceased I entered the shed and was surprised how big the nest was (football size).
Apparently they won't use the same nest each year so I knocked it down, still being wary just in case. They had vacated the nest thank God!
It brought back memories of my Brother and I as kids in the woods collecting hazel nuts. The hornets swarmed around my brother and I had to throw him in a large trough filled with water for cows to drink out of.He must have been stung 30 to 50 times but luckily they didn't get me. I have had a healthy respect for wasps and hornets since then.
