I know next to nothing about reptiles, but Tobi's idea sounds good to me. Perhaps you could take him walking with you out of the house into the back garden (which I think you call a "yard"). That way, he has the "context" of where he is going.
(PS - nothing to do with the above....It's strange to us how Americans and Canadians refer to a "yard", as in British English this suggests a bleak area with only bare earth or tarmac - e.g. a builder's yard. It is fascinating how some words have different connotations each side of the "pond".)
