Bull Snakes feed on small mammals like rats, mice, large bugs, the young of other snakes and lizards. Bull Snakes are known to be quite defensive and exhibit a bad attitude. They flee whenever they feel threatened by larger predators .They also behave like rattlesnakes, which they resemble, when terrified. They do this by rattling their tails, adopting body posture normally held by rattlesnakes and they hiss. These behaviours are meant to scare the threat away; they do this to mimic an attack. Bull Snakes hibernate during the winter months every year and emerge when the weather changes and it becomes warmer. They shed their skins once they become accustomed to the warmth.


Pituophis melanoleucus sayi usually mate during spring. At this time, females dig sandy, shallow burrows and since they are oviparous, lay three to twenty eggs in a clutch.

Neonates are mostly one to one and a half feet long at birth and often take care of themselves.
