Hognose snakes, recognized by their upturned snouts, are often called “puff adders” or “spreading adders” due to their dramatic defensive displays. When threatened, they may flatten their heads and necks, hissing loudly to mimic more dangerous snakes. If this bluff fails, they frequently resort to playing dead, rolling onto their backs with their mouths agape and tongues hanging out, sometimes even emitting a foul-smelling musk. This article provides guidance on how to respond if you are bitten by one of these unique reptiles.
Understanding Hognose Snake Bites
Hognose snakes are generally considered non-venomous to humans, though they possess a mild, irritating saliva, sometimes called a mild venom. This substance, delivered through enlarged teeth at the back of their mouths, is designed to subdue prey like toads, not to cause significant harm to humans.
A hognose snake bite typically results in localized symptoms at the bite site. Symptoms include minor puncture wounds, swelling, redness, and mild pain, similar to a bee sting. These effects are temporary and resolve within hours to several weeks. Severe reactions are rare and often linked to an individual’s allergic sensitivity.
Immediate Steps After a Bite
If bitten by a hognose snake, it is important to remain calm. Panicking can increase your heart rate, potentially accelerating any localized reactions. Gently move away from the snake to prevent further bites.
Next, thoroughly wash the bite area with soap and lukewarm water to cleanse the wound and reduce the risk of infection. If there is any bleeding, apply gentle, direct pressure with a clean cloth or bandage until it stops. You can then cover the bite loosely with a clean, dry bandage.
It is important to elevate the bitten limb if possible to minimize swelling. Avoid applying ice, which can damage tissues, and never use a tourniquet, as this can restrict blood flow and lead to more severe complications. Do not attempt to cut the bite or suck out any venom, as these methods are ineffective and can introduce infection.
When to Seek Medical Attention
While most hognose snake bites are minor, certain situations warrant professional medical evaluation. Seek immediate medical attention if you develop signs of a severe allergic reaction, such as difficulty breathing, widespread rash, or dizziness. These symptoms indicate a systemic response that requires prompt treatment.
Consult a healthcare provider if the bite site shows signs of infection, such as increasing redness, warmth, swelling, pus, or a fever. If the bite is on a sensitive area like the face or neck, or if the individual bitten is a young child, elderly, or has a compromised immune system, medical assessment is advisable. Finally, if you are uncertain about the snake’s identification or your tetanus vaccination status is not current, a medical visit can provide clarity and ensure appropriate preventative care.
