Well, a charmer I am, but not so much with snakes per se, so I’ve no experience to draw upon. But In Arizona there are professional pet finders who deal commonly in these lost pets as well as capture and release. Suppose Arizonans keep a lot of these...might there be such a service in your neck of the woods you could enlist? Sooner the better.
The only people who ‘look for snakes’ here are exterminators.
