We get them occasionally the same
Couple of years on the trot but nothing yet this year (they must have moved to yours)
They're no problem at all, ours were in the eaves, but they didn't even bother going into the loft
Just leave them and they'll just move on later in Summer
One year we saw what I assume was their queen arrive...it was like a flying mouse, ****ing huge
By the way I found a dying bee t'other day and tried to revive it with sugar water...it worked and it flew off 5 mins later.
Bees are cool
The motorcycle outriders would have been a clue.
Edit. Not motorcycles but Vespa's.
