Keep your area free of food and habitat for rodents, because
they are the snake's buffet. No rodents, snakes will go elsewhere.

Good advice. Another thing that will help is to keep your lawn very
short and don't offer them shrubbery or other cool, shady places to get
next to the house. There's a product called "Snake-Away" that you
sprinkle to create a boundary around your yard that (allegedly) snakes
won't cross. I don't know whether it works. It smells like mothballs.
Incidentally, it might be good for the OP to brush up on identifying
poisonous snakes.
