"Wasps do not generally return to the same place year after year,
however some roofs are favoured for their position and habitat."
I have had for a couple of years wasps trying to build a nest in my
shed, I catch them early and use a fly spray, then run like hell. I do
this a couple of times when there are few wasps around and it just kills
them off and stops the nest building.
I think you need to catch them at the beginning of the season before the
colony builds up as they are agressive little s....!
