Eastern Rat Snakes (Pantherophis alleghaniensis = P. obsoletus obsoletus) are a common sight this time of year around homes, buildings, forest edges, and on road surfaces. Many people call them Black Rat Snakes or Black Snakes. Regardless of what you might call them, Eastern Rat Snakes are non-venomous (they’re constrictors), are not aggressive, and pose no risk to people, cats, or dogs. As with other snakes, if you simply leave them alone, they’ll leave you alone.
Eastern Rat Snakes are generally active during the daytime and are semi-arboreal (spend part of their life in trees). It’s not uncommon to spot one in a tree, bush, or up in the rafters of a building. They’re large, growing to a length of 5 - 8 feet, which is probably why some folks fear them. Mice, rats, voles, and chipmunks are common prey, so these harmless snakes are a *great* form of natural pest control around the your yard or on the farm.
This one is displaying its kinking behavior. It’s thought that they do this when they feel threatened while on the ground. Its irregular outline may aid in camouflage from predators in certain situations. Copperheads, hawks, raccoons, and coyotes will eat Eastern Rat Snakes but their biggest threats are likely cars, lawnmowers, and people with a misguided fear of any snake.
