Caution! Snakes, scorpions and spiders lurk near campgrounds – beware!

By Nanci Dixon
Camping in the Southwest? Hiking? Even if you’re just going for a leisurely stroll around the campground you’ll want to watch out for the biting, stinging creatures that call the American Southwest home. If they feel threatened, they’ll defend themselves.

We spend the winters in a regional park in the Arizona desert and I have learned a lot about snakes, scorpions and tarantulas. Here are a few things to note about each:


1. Don’t go off-trail. It is easy to get lost; the desert surface is delicate; and snakes, scorpions and other biting creatures can be hiding under rocks and brush where you can’t see them. The rattlesnake in the photo below was slithering through our campsite.

2. Always watch where you are walking – in front and to the side. Don’t back up to take that stellar photo without looking behind you first. A ranger in Saguaro National Park told me that a young man had backed up for a photo and stepped on a rattlesnake, with severe results.

3. Rattlesnakes hunt at night so you must be extra vigilant if you’re out walking then. Interestingly, they are not as likely to be out on a full moon because their prey can see them! Snakes don’t hear – they feel vibrations and usually consider you too big a predator.

4. Rattlesnakes are not highly aggressive, so back away slowly if you encounter one. Give them a wide berth. A snake can strike up to a distance of half their length. When my husband encountered a coiled snake, rattling, he ran about two blocks before he tried to take a photo. Can’t see a thing in the photo, no matter how much I try to enlarge it!

5. Their rattle is amazingly loud and the rattle is your final warning. Don’t wear headphones or earbuds. In areas heavily inundated with snakes, snake shields and gaiters are available. They might look a bit silly, but if you get attacked, you’ll sure be glad you were wearing them.


6. If bitten, call 911 and get medical attention immediately. Keep as still as possible and keep the area that was bitten below your heart to reduce the venom getting to your heart. Remove jewelry and any tight clothing by the bite area before swelling starts. Do not try to suck out the venom. Let the wound bleed to let out more of the venom. Stay as calm as possible.

7. If you come upon a dead rattlesnake, it is still venomous. A recently killed one still has a muscle that can inject venom, even if decapitated.

8. Snakes semi-hibernate in cooler temperatures. We know that in the spring when the temps start to get to 80 degrees in the day and 70s at night, the rattlesnakes will come out and they will be hungry. Note that baby snakes are born with as much lethal venom as an adult but do not have warning rattles. Be even more aware in the spring and summer.



1. Be careful picking up rocks or sticks. Scorpions commonly hide under rocks, branches, brush and logs. They can also climb and can be found on trees and rock walls. Wear gloves if moving rocks or logs, and double-check for scorpions. I once got a painful sting when I was sweeping. A scorpion got stuck on the broom and the broom brushed against my arm. It hurt for almost a month.

2. Because scorpions can climb they are sometimes found in RVs and homes in dark closets, sinks and bathtubs. Move them out with care.

3. Scorpions come out at night to hunt. They eat insects and sometimes even other scorpions. Closed-toed shoes are recommended when walking at night. Do not leave shoes outside for the night. Tent camping? Shake out shoes, sleeping bags and other items they can crawl into and hide in.

4. Want to go scorpion sighting? They glow green under black lights. You can find small UV flashlights on Amazon. This can be a fun activity but, of course, be careful!

5. The smaller the scorpion, the worse the sting. One of the smallest, the Bark Scorpion, is venomous and considered life-threatening. Beware.


Tarantulas are the stuff of nightmares and horror flicks, but these fuzzy arachnids are basically harmless to humans. When we encountered one on the road I jumped out of the truck to take a picture from a safe distance. The nature center ranger told me I could have put my hand down and it would have gently crawled over. No thanks!

1. If a tarantula rears up on its hind legs, move! It is ready to bite with its front pinchers when feeling threatened.

2. To humans the venom of a tarantula is very weak; however, the bite is painful and feels similar to a bee sting.

3. The venom is highly toxic to dogs and cats, though, and they will need immediate medical attention if bitten.

The desert is an amazing place to visit, live and hike. With a little awareness and respect to the critters that make it their home, it can be your home too, for a day, a season, or years.

There is an annual rattlesnake vaccine for dogs, and since dogs always explore nose first, it adds peace of mind when exploring with dogs. Snakes are attracted to water sources, so don’t turn on a hose in the dark, check with flashlight before turning on.

Hey Nanci! Tell Jimmy he doesn’t need to run that far to get away. At Boyce Thompson Arboretum one year, a Western Diamondback just like your stretched-out one came under the mh to investigate our cat Zoe while she was in her outdoor net enclosure. She saw/heard the snake, hit the wall of the enclosure so hard it tipped onto the side, and she rolled herself away from the rattler… quickly! The snake coiled up under our steps until the mtnce team came to relocate it. Glad to hear you’re @ WTMRP again – say hi to all our friends for us!

That IS a rattlesnake, a Western diamondback, commonly called a Coontail because of the tail markings.

The picture in the post earlier wasn’t a rattlesnake. Nanci went in and corrected the picture when she realized (from our always-astute readers’ comments) that she had inserted the wrong image in the post. 🙂 —Diane at

Thanks for the clarification. If you click on the photo you can see 4-5 rattles on the tail. One snake species that is aggressive is the Sidewinder. They will wiggle themselves into soft sand so that only their eyes and a small portion of their head is above ground. If harassed they will move quickly in your direction…and they can move very fast.

Definitely a rattler. But, the Mojave rattlesnake can fool ya. Since this one’s white tail bands are wider than the black, I suspect it’s a Mojave. I wouldn’t try inspecting head scales to tell for sure!

Nice article, I knew there was a reason I avoid the southwest. I think you mean to say “Sting” when referring to scorpions. They may or may not bite, I don’t know. But their venom is carried in the telson (the tip of their tail).

Good information, however, the info regarding baby rattlers completely contradicts that quoted in the related article referenced at the end…”How to keep rattlesnakes away from your RV”. Either way, being aware and vigilant is probably the most important take away from both articles.

Thank you for posting this because I thought the same thing but wasn’t sure.
