If it's a non-poisonous one, let them be if you can. Our house was just painted and when the painter was pushing back the bushes near the house, two were in his way. Both were "good" snakes, but eewwwww.....he just picked them up with his painting pole and moved them to the landscaping near the cart path behind my house.
Treat all snakes as if they are poisonous, whether they are or not. Just remember to keep your garage door closed or if you have a garage screen, make sure it's in place. Don't want the little crawlers in your house.
Guess my response wasn't much help, but snakes do play an important part in the ecosystem around here.
