Just moved into a new home, and we keep finding wasps in the bathroom - several over the last few days, and four today. Sometimes we have the bathroom window open, but after I found the first two this morning, I shut the bathroom window and still found a couple more just now. We do have the bedroom windows open on the same floor, but haven't found any wasps in those rooms. Is it likely that wasps might come into through the bedroom windows and then gravitate to the bathroom? AIBU to think we might have a wasps' nest in the loft above the bathroom? And would we have trouble getting it removed, as it's a three floor house and the bathroom is on the top floor?
