The bull snake is not a venomous snake and does not have poisonous fangs. However, it can deliver a painful bite and will lunge at anything it finds threatening.
Bull snakes are native to the central United States and can be found from Texas all the way to southern Canada. They are constrictors, which are snakes that kill by coiling around their prey and suffocating them, and are considered beneficial to human beings because of their role in rodent control. Their primary prey include mice, rats, gophers and ground squirrels. They also are known to eat rabbits, lizards, ground-nesting birds and birds' eggs.
