Well, I've tried the heating pad and box thing. The snake got into the box, but there's a reason these little boogers are called "little black racers". Those suckers are fast. It will cost $200 to get a pest removal company out here, and they would have to destroy the snake if they come out. One of the companies advised a different method, which will kill it, but at this point, it's probably going to die anyway, since I'm having no luck capturing it on my own.
