A bit OT but I've seen quite a few threads here about them here...

I found four large, very dozy wasps in the bathroom yesterday.
Bathroom is currently open to the attic space because of some ongoing
d-i-y on the ceiling, so I'm sure they must have come from there.
We've had several nests up there over recent years.

But I thought only queens hibernated; is it really likely I've just
copped for four of the damned things at once? I don't know how much
bigger they are than normal wasps, but mine seemed on the large side
of 'standard'. If they were indeed queens, presumably the problem is
now over?

Before I get the ladders and torch out, can anyone shed any light on
this for me?

Many thanks
David
