Natural predator? Not really.... Not for the adults anyway. For the larva there is. Woodpeckers. But they tear up the wood more than the bees.
Not sure what, exactly, you are trying to protect, but insect screening is actually the the best thing to use. Fit it in so the bees can't get in to where they're boring.
Just using insecticides to treat the holes means that they'll be back next year to try again. Screen them out.
