We must have had colder nights than you, nearly all our bees and wasps are gone.

I drilled several, various size holes in a piece of 4”x4” scrap timber and hung it in a tree.  Quite a few holes have been sealed up this year, I assume someone taken up residence.
My Oregano was a lottie favourite with the bees around here.
