When I returned home yesterday I found a wasp inside sitting next to the Buddharupa we keep in the entrance hallway. I stuck the open end of a glass vase over it and slid paper underneath and took it outside. We've also been informed that Tasmania is 'wasp central' come summer time, so yesterday was a timely reminder to tell the kids to close the doors lest one of the wasps gets inside and stings someone if they inadvertently step on it barefoot or brush it with a hand.
My suggestion to you is to be vigilant with denying access indoors - blocking gaps and keeping windows and doors firmly closed. Blocking gaps under doors, etc. I would also look at seeing whether citronella repels wasps. Its a natural repellent for mosquitos and other insects, and if it has the same effect on wsps, you may wish to invest in some citronelle candles.
I also suggest that during this time you develop the paramita of equanimity in dealing with wasps that come inside.
“No lists of things to be done. The day providential to itself. The hour. There is no later. This is later. All things of grace and beauty such that one holds them to one's heart have a common provenance in pain. Their birth in grief and ashes.”

Learn this from the waters:
in mountain clefts and chasms,
loud gush the streamlets,
but great rivers flow silently.
