ok i live in arizona, and i encounter ratlle snakes every summer/spring...
it depends if you want to kill them or just get rid of them... you could buy one of those long sticks with the claw at the end and pick them up and throw them into a empty trash can...
call animal control or the fire department, but thats kind of puss...
one thing that ive noticed that paralyzes these bitchs for awhile where you can sneak up on them and get a good kill is to pull out your hose on full blast and spray these bitchs, they hate the water and seem to barely move when you give em' a quick dose of that h2o
buy your a very long flat head shovel, remember the easiest way to kill these bitchs is to cut their head off, but remember the head and the body can still move so dont be dumb around the decapitated head...
or best bet is to just let them pass, unless they are trying to stay around your crib then you got a problem.... a couple of these tips should help... but remember they can strike fast, ive never been bite by one but ive killed a couple
