Dealing with Venomous Animals on Arizona Hiking Trails
For several years hiking has ranked as the most popular outdoor activity in the United States, with approximately 60 million American hikers. Hiking provides many physical and mental health benefits, ranging from improved cardiovascular fitness to reduced levels of stress. It does entail some risk, however, including potentially dangerous encounters with local wildlife, meaning hikers should take certain precautions to stay safe.
Hikers in Arizona need to be especially wary of the state’s many venomous creatures, including scorpions, spiders, and snakes. Over 60 scorpion species are native to Arizona. The Arizona bark scorpion is both the most common and most venomous of the state’s scorpion population. Following a sting, adult hikers typically experience pain at the site of the sting, as well as numbness. However, senior hikers, children, and any hiker with a compromised immune system can experience much more serious symptoms, including loss of vision, impaired mobility, and fatal reactions.
Hikers should seek medical attention following a scorpion sting. Individuals should stay hydrated, while avoiding alcohol and aspirin. Fortunately, bark scorpions are not aggressive and generally avoid human interactions. Hikers who encounter scorpions on Arizona hiking trails should move away slowly without making sudden movements. If absolutely necessary, they can use hiking poles to gently move the creature to a different location.
Numerous spider species can be found in Arizona, including black widows. While black widow bites do not usually cause fatal reactions, hikers can experience a range of symptoms depending on how much venom the spider injects. A cousin of the brown recluse, brown spiders pose a similar threat to Arizona hikers, with the potential to cause painful necrotic wounds, which individuals may struggle to treat on remote hiking trails.
Like scorpions, black widows and brown spiders only bite when they feel threatened. Individuals should carefully check woodpiles, logs, rocks, and other cool, damp places where spiders may live. If a bite occurs, hikers should clean the wound with soap and water, apply ice, and elevate the wound. Without medical treatment, individuals may develop symptoms such as nausea, fevers, respiratory issues, and increased blood pressure.
The United States is home to 36 rattlesnake species, 13 of which live in Arizona. They are especially common near Camelback Mountain, South Mountain, and in the state’s desert regions. Snake bites are considerably more dangerous than scorpion and spider bites, meaning hikers of any age should immediately seek emergency medical care following a bite. Rattlesnake bites are painful and cause bleeding, swelling, and bruising. The venom disrupts the body’s blood system, making it difficult for blood to clot properly.
Common mistakes after a rattlesnake bite include trying to suck out the poison, applying ice to the wound, and using a tourniquet. Antivenom is very effective for treating snake bites, though hikers may experience tissue damage and need to spend a few days in the hospital. Full recovery can take anywhere from a few weeks to several months, with potential long-term symptoms including nerve damage, tissue loss, and amputation.
Fortunately, rattlesnakes use their hallmark rattles when they feel threatened. Rattlers’ identifying characteristics include their triangular heads and ringed tails. Individuals who hear or see rattlesnakes on Arizona hiking trails should calmly move in the opposite direction and seek an alternate route away from the snake’s location. Hikers should remain vigilant for rattlesnakes in various Arizona habitats, including forests, deserts, mountains, and plains.
