I have a cat to take care of the mouse population and she does a good job. I don't need any snakes around. As far as i'm concerned the only good snake is a dead snake. I see one in our yard I chase it down and kill it. I don't care what kind it is. I'm not gonna ask for ID first. I don't know one snake from another and i'm not gonna take the time to look it up first. We once had a 6 foot chicken snake in the house. After DH killed it, we moved.
