Honestly I see nothing wrong with anything OP has posted. Everyone else snapped to the conclusion that he may have actually lost his snake, which isn't an alarming issue. You wouldn't really be able to lure your snake anywhere as they enjoy roaming around at late hours, and exploring the place.

As posted above, placing water bowls around the place will ensure your snake has ample water during their excursions. Doing things like pouring salt/sugar/flour along doorways and hallways allows you to track what direction your snake may have been going in. Using plastic bags can also give you a heads up if you happen to hear them rustling as a snake travels over them. People have suggested trying to lure a snake from their hiding places by using food as a tool. I have no idea if that would ever work, nor do I believe that would work in a timely manner.

The most you can do is provide water, and actually do the searching for your snake. They aren't exactly going to come back to you when called. Nor will they make noises of their own just because you are also making noise at them.
