If it is eating pinkies then get one of those mice breeding cages and put a live pinkie inside. The snake crawls through the space in the cage bars and eats the pinkie and just stays there. This has worked for a friend of mine. If the snake is on bugs then I'mnot sure what to suggest. Leave out a water bowl near where you think the snake may be so it can drink if it wants to. Also you can sprinkle baby powder on the floor to see if the snake has moved across the floor or not. Check dark warm places.
