Identifying Pennsylvania's Poisonous Snakes: A Guide to Safety
The primary goal of this article is to educate readers about the poisonous snakes found in Pennsylvania, enabling them to recognize these snakes and take appropriate safety measures. This guide will focus on "pennsylvania poisonous snakes" and how to avoid encounters.
Understanding Venomous vs. Poisonous
It's important to start with a clarification: While often used interchangeably, venomous is the correct term for snakes that inject toxins through fangs. Poisonous refers to organisms that release toxins when touched or ingested. Since snakes inject venom, "venomous snakes" is technically the more accurate term. However, to align with the article's title and target keyword, we'll primarily use "poisonous snakes," remembering this distinction.
Pennsylvania's Venomous Snakes: The Players
Pennsylvania is home to only a few species of venomous snakes. Identifying them correctly is crucial. This section will provide detailed descriptions of each.
The Copperhead (Agkistrodon contortrix)
The Copperhead is the most commonly encountered venomous snake in Pennsylvania.
- Appearance: Characterized by its distinctive reddish-brown, hourglass-shaped crossbands on a lighter tan or pinkish background. The head is copper-colored, hence the name. Young Copperheads have a bright yellow or greenish tail tip used to lure prey.
- Habitat: Prefers wooded areas, rocky hillsides, and near bodies of water. Often found in suburban areas.
- Behavior: Generally not aggressive, will usually remain still, relying on camouflage. Bites occur when they are accidentally stepped on or disturbed.
The Timber Rattlesnake (Crotalus horridus)
The Timber Rattlesnake is the largest venomous snake in Pennsylvania and is considered a species of concern.
- Appearance: Exhibits two color phases: a yellow phase and a black phase. Both phases feature dark, irregular crossbands along their back. The rattle on the tail is a key identifying feature, though it may be broken off.
- Habitat: Primarily found in mountainous and wooded regions. Prefers rocky outcrops and dense vegetation.
- Behavior: Usually reclusive and will attempt to avoid confrontation. Will rattle its tail as a warning if threatened.
The Eastern Massasauga Rattlesnake (Sistrurus catenatus)
The Eastern Massasauga Rattlesnake is a smaller rattlesnake and is listed as a federally threatened species.
- Appearance: Typically gray or light brown with dark brown or black blotches along the back and sides. Possesses a rattle on its tail.
- Habitat: Found in wetlands, including bogs, marshes, and wet meadows.
- Behavior: Usually docile and will attempt to escape if disturbed. Their small size and camouflage make them difficult to spot.
Differentiating from Non-Venomous Snakes
It's important to know how to tell the difference between Pennsylvania's poisonous snakes and the many harmless snakes that call the state home. Mistaking a harmless snake for a venomous one can lead to unnecessary fear and potential harm to the snake.
Key Distinguishing Features
| Feature | Venomous Snakes (Copperhead, Timber Rattlesnake, Massasauga) | Non-Venomous Snakes |
|---|---|---|
| Head Shape | Triangular | Oval or rounded |
| Pupils | Vertical, elliptical (cat-eye shaped) | Round |
| Pit | Presence of a heat-sensing pit between the eye and nostril (Copperhead and Rattlesnakes) | Absence of pit |
| Rattle | Presence of a rattle (Rattlesnakes) | Absence of rattle |
| Coloration/Pattern | Refer to specific snake descriptions above | Highly variable, depends on species |
Note: Relying solely on head shape can be misleading. Some non-venomous snakes can flatten their heads to appear triangular. The best approach is to observe multiple features.
Common Non-Venomous Snakes
- Garter Snake: Very common, variable coloration.
- Black Rat Snake: Large, black, excellent climbers.
- Eastern Milk Snake: Variable pattern, often confused with Copperheads by inexperienced observers.
- Northern Water Snake: Found near water, can be aggressive but harmless.
Avoiding Encounters: Safety Tips
Prevention is the best defense against snake bites. This section outlines practical steps to minimize your risk of encountering venomous snakes.
- Be Aware of Your Surroundings: Pay attention to where you're walking, especially in wooded areas, rocky terrain, and near water.
- Wear Appropriate Footwear: Sturdy boots that cover the ankles can provide protection against bites.
- Stay on Marked Trails: Avoid venturing off established paths, where snakes are more likely to be undisturbed.
- Use a Walking Stick: Poke around bushes, logs, and rocks before reaching into them with your hands. This can alert snakes to your presence.
- Be Cautious Around Woodpiles and Rock Walls: These are common hiding places for snakes.
- Keep Your Yard Clear: Remove brush, woodpiles, and other debris that could attract snakes.
- Supervise Children and Pets: Teach children to recognize snakes and to avoid approaching them. Keep pets on a leash in areas where snakes may be present.
- Never Handle or Provoke Snakes: Even if you believe a snake is non-venomous, it's best to leave it alone.
What to Do If Bitten
Knowing how to respond to a snake bite is critical.
- Stay Calm: Panic will only increase your heart rate and spread the venom more quickly.
- Move Away From the Snake: Ensure you are no longer in danger of another bite.
- Call 911 or Seek Immediate Medical Attention: Even if you're not sure if the snake was venomous, it's best to err on the side of caution.
- Identify the Snake (If Possible): A photograph from a safe distance can help medical professionals determine the appropriate treatment. Do not attempt to catch or kill the snake.
- Remove Jewelry and Tight Clothing: Swelling may occur.
- Keep the Bitten Area Below the Heart: This can help slow the spread of venom.
- Do NOT Apply a Tourniquet: This can cause more harm than good.
- Do NOT Cut the Wound or Attempt to Suck Out the Venom: These methods are ineffective and can increase the risk of infection.
Important Note: Antivenom is the primary treatment for venomous snake bites. The sooner it is administered, the more effective it will be. Therefore, seeking immediate medical attention is paramount.
