I'll start by saying this has never happened in over 20 years of living in my house.
4 wasps appeared in my house this past week. FOUR!!! At most in previous years we've had 1, but over my 20+ yrs here that's like 1 wasp in 5+ yrs on average.
Between 2-2.5cm long so all queens from what I've read.
Do I have a nest or could they be scoping out to start one? I don't know what to do but the internet is filling me with fear. Need some helpful first hand experience before I run away until the winter.
