Common Snake Species in HarrisburgRat Snake: The eastern rat snake, also called the black rat snake, is one of the largest snakes that can be commonly found in Pennsylvania. They feature a black or dark brown body with white throats. This non-venomous snake feeds on a variety of prey, such as rodents, birds, amphibians, and other snakes. The eastern rat snake can be anywhere from three to eight feet long and is excellent at climbing trees and structures. They have been found around urban areas, as the only real requirement for them is that they have access to rodents, which in some urban areas, there is an abundance of. These snakes are harmless to humans other than a painful bite if they are startled.
Garter Snake: The eastern garter snake is one of the most common snakes in the United States, and Harrisburg is no different. In fact, the garter snake is the single most common snake in urban areas. They can thrive in highly urban areas, as they feed on a variety of insects and other small creatures. These snakes have dark backgrounds with light-colored stripes and bellies. The garter snake can be anywhere from one to four feet long. Eastern garter snakes are completely harmless to humans, and they are often beneficial to keep, as they take care of less desirable insects.
Milk Snake: One of the most misidentified snakes in Pennsylvania is the milk snake. They are often killed because they look similar to copperheads. The surefire way to tell them apart is that eastern milk snakes have markings on their head, while copperheads have a solid copper-colored head. Milk snakes’ bodies feature light-colored backgrounds with dark splotches around them. These snakes love to feed on mice and other less desirable animals, making them a great snake to keep around. The eastern milk snake can live in a variety of habitats, from woodland to urban areas, making them incredibly adaptable to living near Harrisburg. In fact, milk snakes enjoy living near buildings and semi-urban areas because they often find large rodent populations, which they can feed on. The eastern milk snake is harmless to humans other than the bite they can leave if they have been startled or handled.
Venomous Snake Species in HarrisburgCopperhead: Copperheads Like much of the eastern United States, the state of Pennsylvania contains the eastern copperhead snake. Named for its unique copper-colored head and body design, this snake is venomous and can be very dangerous for humans. While the bites are oftentimes dry, meaning there is very little to no venom injected, some bites can be lethal. The eastern copperhead is anywhere from two to three feet long and has a triangular head shape. The copperhead mostly only strikes when it is startled by someone, rarely biting a human just because. They commonly eat small mammals, birds, amphibians, and even other snakes.
Rattlesnakes: Pennsylvania is home to two venomous rattlesnakes, the timber rattlesnake, and the eastern massasauga. While it is rare to find these snakes in an area like Harrisburg, it is always possible and potentially deadly. That is why it is important to be aware of the poisonous snakes of the state. Timber rattlesnakes grow to be quite large, sometimes up to six feet in length. They are easily identified by their unique design which consists of V-shaped dark bands around a lighter colored background of their body. Their heads and eyes can either be darker colored or yellow colored. The eastern massasauga is smaller, generally around two to three feet in length. They feature a gray background with dark splotches all around its body, in addition to a black belly. Both the eastern massasauga and the timber rattlesnake have venom that is capable of causing death to humans. While they generally do not attack unless provoked, it is smart to always exercise caution around them.
