Need to identify a snake you’ve seen? Click here for a guide to identifying venomous snakes of north Texas.
The Texas rat snake (Pantherophis obsoletus) is one of the more common large snakes in north Texas. It is a harmless snake that grows to about four to six feet in length - and the record length is a little over 7 feet! Because these snakes are excellent climbers, they may follow creeks through residential neighborhoods and are sometimes discovered by frightened or concerned homeowners. Their diet includes rats and mice, and since they are non-venomous, they are valuable snakes to have around.
