Good news. I checked him this morning after the treatment of his temporary home (and him as well) found about 8 of those bastards on him so in a small shallow plastic container he went to soak.

So far they've all fallen off. I retreated just the walls and paper towel with the nix solution.

I'm hoping that's all there was and that this was just a few it picked up from the expo and it's all done now but it's staying in the room over from my other 6 BPs until I know for sure.
