I am against snakes. Each one I find on my property is promptly dispatched by 1911 in .45acp. While I understand some snakes are harmless and helpful, I am not going to try to decide if the one I am about to shoot is in the helpful variety. I just shoot them and call the Chief to tell him to ignore gun shot calls to the neighborhood as it was me shooting a snake. He hates them more than I do.
There is something in that house that the snake smells and wants !!! Something you don't know that lives in your house !!!
