I agree with you ButterflyLady29, wasps don't really hold much fear if you don't suffer a reaction. I once sliced through a nest the size of a football with a hedge trimmer and got stung about ten times....the thing with wasps stings is they are momentary intense pain but very little thereafter and no long term rash or lumps for those that don't get an immune reaction.
Flies, however, scare the life out of me, I have had a misshapen face and huge lumps over the years, they are silent and deadly.
However, having read that a wasps nest can reach the size of a small armchair and the fact I am having a roofer over the next few weeks has swung it for me. Tbh the activity is pretty intense...at least 100 wasps coming and going every minute. My neat mind, and the fact that it wouldn't be fair on the roofer has decided it. £63 for the local council.
