One of the best ways to dispatch snakes safely is Wasp and Hornet Spray. It is a nerve agent that causes near instant paralysis and death in snakes as well as insects. I used it frequently when working patrol as a police officer. I was the snake guy on the shift because I am not afraid of them. I do have a healthy respect for the poisonous ones. They were the ones that got the spray. The rest got caught and moved. It would amaze you how many "snake in the house" calls you get in the south.
