Checking In With Our Rattlesnake Guy On What To Do This Season Get our free mobile app I got to get up close and personal with Diamondback's rattlesnakes, bust some snake myths, and learn how to keep my family and pets safe. The most important bits of info for you to take away are how you can "rattlesnake proof" your home and yard, and what you should do if you come across one. If you see one, stay calm. Slowly walk away. When it comes to your house and yard, get rid of the clutter and keep the grass mowed down. That's the best thing you can do.
