Use the Sevin dust. They will carry it in to their nests and kill the Queen, hopefully. They can be difficult to totally remove as you have already noticed.
Along those same lines, I use a commercial grade dust called Drione. It's deadly on yellow jacket nests no matter how badly dug in they are. Used it a couple years ago on the carpenter bees that were drilling holes in the wood framing of my pole barn. Haven't seen them return. Don't plug up the hole after applying. Let the bees carry it in & out.
I just shoot them with an old pump gun and 22 bird shot. When we had the farm there was a 2x10 header board on one of the lean tooo's. Them damn things just loved that board. Fun way to relax after a days work.

Now here's a man with a plan!!!! Through in a "few" cold beers and you're good to go!!!LOL
Got them on a picnic table I made. I stained and sprayed the top but not underneath. They prefer unstained or treated wood. Just do like a bee hive wait till dark when they go in and spray black flag in the hole. Then plug with puddy and finish the wood. Watch those posins the will kill pets and kids also.
after a few too many beers we sprayed something (don't remember what) in the holes and hit em with a lighter. Kept them away for a while but the wife wasn't happy about the roof over the deck burned to hell. It was a good night though.

I had a 22 pistol with the rifling almost shot out of it. It made short work of those guys with CCI shotshells.
