When do Wasp Nests start and how?

When do wasp nests start? You can quite clearly see here a new queen wasp crawling over a new stalk she has made that is fixed from inside a shed roof. This forms the very start of a wasp nest that could be up to 12-foot across at the end of summer!

The second photo here shows the stalk without the queen wasp on it. She has probably just flown out for something to eat. She’ll return soon. This photo was taken on 23rd April 2019.
