Maybe a call to the local council pest control for advice and to see if they will spray the attic with the stuff they use on wasps nests to hopefully kill any scouts before they get interested in the new 5* residence they have just found
I am probably wrong but I wouldn't be surprised if wasps do leave chemical trails or something similar which other wasps can follow (just looked it up they do) so chances are while that trail exists, you will have more visits/nests. I would hope the pest control officers could offer some advice on neutralising those trails or even make them into something that would repel the little buggers instead
