I'm all for avoiding bites, believe me. When snakes are "out & about", that takes a different technique to service their homes. I usually take a few moments to fully identify myself to them by scent, then touch, so they know there's no incoming food. Another way of "changing their channel" is a little directed water mist. We all need to do what works for us & our own snakes. Snake-keeping is not a "one-size-fits-all"- it just helps to have options to keep in mind, then do what works for you.
