Never found any snakes in my yard, since snakes are not likely to come down here from the mountains. Though, I find many lizards around such as Arizona Whiptails. If I ever find a snake that is not venomous I would most likely just take a look and it and handle it a bit, then most likely go somewhere where it wouldn't come in contact with people much or on a hiking mountain. If it were to be venomous, simply calling animal control to remove the snake would be the safest way. The snake doesn't want to die, and was probably out hunting for something to eat. And I always remember, it's us that have moved into their territory so there is no need to kill them for coming into our yard that once was their territory.
