For those caught unawares, Arizona is a downright dangerous state. Grand Canyon National Park has been repeatedly ranked as the most dangerous park in the country; but the hazards don’t stop there — Arizona is home to myriad dangerous animals and insects. Some, like the infamous Arizona rattlesnakes, post well-known threats; others, such a particular breed of beetle, are seemingly innocuous creatures with the capacity to kill. If you’re headed to The Copper State, you’ll want to steer clear of these nine most dangerous animals found in Arizona.

  1. Snakes

While rattlesnakes give a distinctive warning sign before they strike, if you do get bitten, it’s crucial to seek immediate medical attention, as rattlesnake venom can cause tissue death – and even kill you.

  1. Gila monsters

While this lizard is actually quite stunning, they’re best enjoyed from afar, as the Gila Monster is venomous. Like many snakes, the Gila Monster’s bite releases a neurotoxin that can attack your body and can cause swelling, irritation, paralysis, and even death.

  1. Sonoran Desert toads

These toads secrete a strong toxin from their glands that can coat their skin. While generally not an issue for humans; for dogs, these toads pose a huge risk, who often sniff at, or pick up, animals they find. An encounter with a Sonoran Desert toad (also known as the Colorado River toad) can be a death sentence for curious canines.

  1. Mountain Lions

While attacks on humans are rare, you’ll want to exercise caution when in their territory – especially if you have Fido in tow, as mountain lions have been known to attack dogs.

  1. Tarantula Hawks

One sting will leave you doubled-over for the most excruciating three minutes of your life. If you’re going to the Grand Canyon, keep an eye out for these insects, who seem to really enjoy the scenery there.

  1. Spiders

The Black Widow and Brown Recluse both call The Copper State home, and one bite can cause a host of problems, including swelling, difficulty breathing, and, in some cases, even death.

  1. Kissing Bugs

These bugs are actually bloodsucking insects that carry parasitic disease. Perhaps most terrifying, they inject an anesthetic similar to bed bugs – so that you aren’t aware of having your blood sucked for 20-30 minutes. You’ll realize after the fact, by which time, it will be too late: you’ll be dealing with headache, rash, fever, fatigue, body aches, and gastrointestinal distress.

  1. Black Bears

While black bear attacks in Arizona are generally rare, continued human encroachment into their territory has caused a rise in encounters. Black bears are intelligent, incredibly strong, excellent climbers, and fast: they can run up to 30 miles per hour.

  1. Scorpions

This venomous creature is ubiquitous in Arizona, found everywhere from rock faces and in trees, to basements and storage closets – in people’s houses.

  1. Arizona Giant Centipedes

The eponymous Arizona Giant is extra creepy because it’s huge (over eight inches long, with 42 legs) and extremely venomous. They have two front legs that act like fangs, which they use to inject venom. While death by centipede venom is rare, getting bit by one of these insects is extremely painful.

Sometimes the most beautiful things are the most dangerous.

While absolutely resplendent, Arizona is also home to many dangers — some very obvious and known; some hiding in plain sight. Commit this list of dangerous animals in Arizona to memory, and be sure to exercise caution when exploring The Grand Canyon State!
