I was investigating the attic of an old house we had just purchased, looking for the spot where water was seeping through the roof. In the middle of the floor, I saw a snake skin, I could not believe it was there. I had been in the attic several times previously and the snake skin had not been there.
I am not afraid of snakes as a rule, but I would rather not have them in my house. I could not tell from what type of snake the skin came. My biggest concern was that it might be a poisonous snake.
I found the discarded skin during the winter. Once the weather warmed, I thought we might she the snake in the house. One day when I was doing some work at the house I saw a black snake climbing from the attic vent and down the gutter.
At the time, I didn't know what type of snake it was, but after reading this article I think it was a black rat snake. It was at least six feet long and the coloring described in the article matches the snake I saw. After that, I saw the snake around he house several times, so we decided to trap it and relocate it.
I have heard that snakes can be territorial. That one seemed to have no intentions of moving on, and I did not want him back in the attic the following winter.
