I hate the idea of killing the Queen (if she is one) as the wasps are a huge help I'm keeping pests down in our garden. We're going to snoosh the nest and hope the wasp moves on.
Whilst you may hate the idea, leave it and you will not be able to go in the shed this year because of all of the queens mates. You need to twat it with a long stick now, none of this snooshing.
