Ahhh! My first escape in years!!

I'm so sorry! Sounds like you've done all you can do, although my corn snake book suggests the following ideas:

Place live baby mice in a bucket filled with substrate and a hide from the cage so the snake recognizes its own smell. The idea being they smell the food, eat, and then snug down in the bedding to digest.

The other way is to fashion a sort of "fish trap" for the snake so he can crawl in but can't crawl out. Take a piece of PVC pipe and 2 pieces of stiff paper. Roll the paper into cones and cut out a hole big enough for the snake to crawl into. Tape the cones inside the PVC pipe so the point of the cones point inside. This way when the snake crawls in, he can't find the opening easily because he'll be bumping against the bottom of the cone with no opening. Lay the trap along any room perimeter; it's more likely he'll be moving around walls and not in the center. You can go a step further and bait the trap either with food odor or live bait.

Can't say from experience these techniques work, but it's advice from a published source (Kathy and Bill Love).

Hope you find him soon....
