I am delighted to say that all of the wasps have gone. We can open the bathroom window again without fear!

Hi Jon,
I’ve been into the garage and as far as I can tell there are no more wasps in the nest area. Thank you for your help and quick service. I hope you don’t mind a I passed on you number to a family friend who had a wasp problem.
Thanks again
Lucy
