I live out in the desert and we have a preserves on both sides of us...even though it is a community. We see rattle snakes on a yearly basis. Personally scares the bejezus out of me. We do teach desert safety and we teach kids not to do certain things. One being...if the ball goes under a bush....get a rake to get it....do NOT reach in and get it. Be aware when you are out in the desert ..listen and look. We also take precautions to make sure that our backyard is blocked off. We net off the holes in the walls that allow water to flow out....make sure our gates are tight to the ground etc. If and when I see rattle snakes...we have a number to call so they are relocated. However lots of others kill them. We also have many kingsnakes here...those are treated like little gods around here.
To me if it can be relocated...then do it. After all...we moved into their turf.
