Common Snake Species in Philadelphia

Philadelphia snake Northern Ring-necked Snake: This is a small snake with distinctive features that are easy to identify. A northern ring-necked snake is a non-venomous snake with an average length of 12 to 15 inches. Despite being harmless, these snakes appear harmful mainly because their upper body is olive-brown to dark gray. When this snake raises its head above the ground, you might also get to see the yellow or bright orange ring pattern around its neck.

Philadelphia snake Eastern Hog-nosed Snake: Here is another non-venomous snake found in Philadelphia. Eastern hog-nosed snakes always try to mimic the deadly cobra by spreading the skin around its head and neck region, while rolling back and forth opening its mouth. With this, it can fend off prey. This eastern hog-nosed is a long snake that can grow as long as 33 inches in the wild. Just as its name implies, it has a pointed upturned nose covered in scales. The upper body of this snake is dark brown to gray with brown blotches.

Philadelphia snake Northern Rough Green Snake: This particular species of snake is common in areas with plenty of trees in Pennsylvania. They are good climbers and can hardly be found on the ground crawling. An adult northern rough green snake is between 22 to 32 inches long. With their long and slender body alongside their large eyes, they can climb trees of any height. The upper body of a northern rough green snake is usually light green, while the belly can either be yellowish-green or cream-colored.

Also, the tail is black to solid brown and the head is triangular, large, and flat.

How to Humanely Get Rid of Snakes
Snakes are harmless and beneficial to our ecosystem. However, thousands of snakes are still being killed yearly due to the common misconception about them. Not all snakes are poisonous; some people, especially those who live in an agricultural setting, even encourage the presence of snakes that will help them manage the population of pests. Snakes will eat rats, mice, and other urban pests; therefore, we recommend using the most humane method if you want to get rid of them.

Ways to Get Rid of the Snakes Humanely
When you see a snake on your property, avoid panicking since it will prevent you from thinking rationally and creating the right decision. First, secure your pets and your kids and make sure that they will stay away from the snake. We advise you to call the assistance of a wildlife removal expert since this will be the safest. Additionally, they will only use humane methods to ensure that the snake will not experience any unnecessary pain during the whole process. However, if you think that is not an option for you, here's how you can do it.

How Should I Start?
Start by identifying the snake; with this, you will be able to determine the behavior of this snake. Snakes are cold-blooded, and they will often look for a place that will provide them with warmth, security, and convenient access to their food source. When inspecting all the possible shelter of the snake, you need to be very cautious. Do not stick your hand on places that you can't see. Wear protective gears and use snake tongs or snake hooks when probing some areas. If you happen to encounter a shed snakeskin indoors, the areas that you need to check will change dramatically. Snakes are very capable of hiding in tiny spaces and places that you don't suspect. They can also climb, so you may want to check your attic.

Should I Use Exclusion or Elimination?
We understand how most of you will not have experience in the proper identification of snakes; therefore, it is always better to consult a snake removal expert. They will identify the creature and provide you with recommendations on how to prevent this from happening again. They can also enlighten you about the existing laws that protect these snakes from improper removal and exclusion.

Finally, you should keep your yard clean. Eliminate the possible hiding places of the snakes, such as the piles of debris and clutters. Trim the low-lying branches of the trees and the shrubs. Mow your lawn regularly and keep it ideally short. Snakes will be drawn to the damp and dark areas of our house. Eliminate their access from that area by surrounding the place with a barrier. Treat your rodent infestation if you want to avoid attracting the attention of the snake. Seal all the possible entry points of the snake using the appropriate construction materials. Rubber sealants, expanding foams, and caulks are all equally effective in sealing the cracks and crevices.

Remember, the term is not poisonous snakes of Philadelphia, it's venomous snakes of Philadelphia. Poison is generally something you eat, and venom is injected into you. That said, dangerous snakes are very rare in Philadelphia. The few venomous snakes of Montgomery County are rarely seen. But they are commonly misidentified, so learn about all the snake species of Philadelphia in order to correctly identify them. These snakes are usually also found in the surrounding towns of Norristown, Pottstown, Lansdale, King of Prussia, Ambler, Collegeville, Horsham, Conshohocken, Blue Bell, North Wales, Souderton, Harleysville, Willow Grove, Hatfield, Royersford, Jenkintown, Hatboro, Glenside, Plymouth Meeting, Montgomeryville, Bryn Mawr, Schwenksville, Fort Washington, East Norriton, Skippack, Wyncote, Narberth, Bridgeport, Eagleville, West Norriton, Wynnewood, Pennsburg, Trappe, Audubon, Lafayette Hill, Arcadia University, Gilbertsville, Gladwyne, Green Lane, East Greenville, West Conshohocken, Flourtown, Oreland, Red Hill, Rockledge, Bryn Athyn, Wyndmoor, Pottsgrove, Sanatoga, Dresher, Maple Glen, and the surrounding areas.
