Where I live now don't see many snakes unless I go looking. Where I used to live I'd see all kinds including timber rattlers. I've never been one for killing them if it was avoidable. Only had to kill 2 that I can recall. One that my dog mangled had to be put out of its misery (an eastern garter if memory serves) and one of the rattle snakes.

Usually tried to catch the rattlers and move them about 5 to 10 miles away but one of them we shot and used it along with a shock collar, and some fishing line to teach our dogs that snake's should be avoided. Did the trick but in hindsight I think a rubber snake would have worked just as well.
