Not all snakes that are found in the Phoenix area are the deadly kind. Still, when encountering a snake you should take appropriate precautions. If you come upon any snake in the desert, the best way to proceed is to steer clear — avoid it and leave it alone. If you find a snake inside your home or in your yard and you aren't comfortable with what kind of snake it is or how to handle it, contact a professional and they will remove it for you.
