Need Advice Carpender Bees

We have several of these flying teddy bear looking bees hanging out under our deck and appear to be attempting to burrow into our deck. What do I do about this? Thanks so much!

 

Also know as the drilling bee because the holes are perfectly cylindrical. I discovered two holes when I spotted saw dust on top of the lawnmover cover and on the patio. You can blow Drione into the hole. It is a desiccant so it dries up the exoskeleton and kills the insect. It's much safer to use than other pesticides, but still use with caution. I applied it using a small bellow.
