I'm not wild about snakes but we live in their territory (Southern California Desert). In 17 yrs. at our home, I've seen three or four rattlers at the house and one king snake. The rattlers want to get away from you asap! The king snakes are not poisonous as they are constrictors.
The only times the snakes come around is when we are not at the house for months at a time. Once we are back home, I think they sense the vibrations and move on. We also have rabbits, scorpions, tarantellas, bobcats, raccoons and black widow spiders. I catch mice in the garage on the glue traps every now and then. You do not want the mice to get in your car engine as they will sharpen their teeth on your wiring.
