Are There Scorpions in Wyoming?

Are They in Wyoming?

Wyoming has no established scorpion population. The state's high elevation and cold climate make it impossible for scorpions to survive here. Scorpions cannot endure Wyoming's long, severe winters, when temperatures plummet far below freezing for extended periods. Most of Wyoming sits above 4,000 feet in elevation, and much of the state exceeds 7,000 feet, which creates conditions unsuitable for scorpion survival even in summer. While an occasional scorpion might accidentally arrive in a shipment from the Southwest, it would not survive Wyoming conditions and could never establish a breeding population. The species lacks the biological adaptations for this climate. The nearest wild scorpions live over 700 miles away in Arizona and New Mexico. Most Wyoming residents will never see a living scorpion unless they travel to the desert Southwest.

How Dangerous Is It?

Scorpions are venomous arachnids that use their stingers to subdue insects and small prey. In the United States, only a few scorpion species have venom potent enough to cause serious medical effects in humans. Most scorpion stings feel similar to a bee or wasp sting, causing localized pain, swelling, and redness that resolve within a day or two. The Bark Scorpion of Arizona is the only North American scorpion species whose sting can cause significant medical harm, including numbness and temporary paralysis in some cases. Even Bark Scorpion stings require prompt medical attention but are rarely life-threatening in healthy adults. Other Southwest scorpions cause only minor local reactions. Scorpions found in other parts of the world can be considerably more dangerous than any North American species. Since Wyoming has no scorpions, this risk is completely absent from your state and your daily life.

How to Recognize One

If you travel to the Southwest and encounter a scorpion, here is how to identify it. Scorpions are distinctive arachnids with eight walking legs, two pedipalps or pincers at the front of the body, and a segmented tail that curves upward and ends in a venomous stinger. Most North American scorpions are colored yellow, tan, brown, or black. Size varies by species, ranging from about two inches to five inches in length. The curved tail over the back is the most recognizable feature. Scorpions have a flattened body profile and are exclusively nocturnal, hunting at night and hiding in dark crevices during daylight. They are attracted to insects and other small creatures.

What to Do If Bitten or Stung

Scorpion stings are virtually impossible in Wyoming because scorpions do not live in the state. However, if an extremely unlikely scenario occurs involving a transported specimen, remain calm. Remove any rings or tight bracelets from the affected limb, keep the area still and below heart level, and wash the sting site with soap and water. Apply a cold compress to reduce swelling and pain. Seek medical attention immediately. Do not cut the sting site, apply a tourniquet, or attempt field treatment. This is general information, not medical advice; if you are bitten, call Poison Control at 1-800-222-1222, or 911 if symptoms are severe. Medical professionals can assess your situation and provide appropriate treatment based on the actual sting and your individual health status.

How to Prevent Encounters

Prevention is straightforward in Wyoming because scorpions do not occur naturally in the state. If you travel to the Southwest where scorpions are present, take basic precautions. Shake out shoes and clothing before putting them on, as scorpions may crawl inside. Wear closed-toe shoes and long pants when hiking or spending time outdoors in desert regions. Check your bed and bedding before sleeping, especially in older hotels and rustic accommodations. Use a flashlight to inspect dark corners, woodpiles, and rock crevices in your lodging. Seal gaps and cracks around doors and windows in your temporary accommodations. Clear away debris and leaf litter where scorpions might hide. When traveling to Arizona, California, or New Mexico, ask locals about region-specific precautions.

Where in Wyoming and When

Scorpions do not inhabit any region of Wyoming during any season. Wyoming's geography is dominated by high mountain ranges, including the Rocky Mountains, the Teton Range, and the Wind River Range, as well as the high plains. Most of the state sits above 4,000 feet in elevation, with many areas exceeding 7,000 feet. These high elevations create short summers and long, severe winters with subzero temperatures. Even the lowest parts of Wyoming, such as areas along the Colorado River border, are far too cold to support scorpions. Scorpions are found exclusively in the hottest, driest regions of North America, primarily the Sonoran, Chihuahuan, and Mojave deserts. The nearest scorpion populations to Wyoming live over 700 miles to the south in Arizona and New Mexico, in low-elevation desert regions.

Harmless Lookalikes

Wyoming is home to numerous harmless arachnids that residents encounter regularly. The harvestman or daddy longlegs resembles a spider with extraordinarily long, thin legs and a tiny round body. Harvestmen are completely harmless, do not spin webs, and feed on decaying organic matter. Wyoming has many species of wolf spiders, which are beneficial hunters that control household insects. Cellar spiders and cobweb spiders are common indoors and entirely harmless. The few huntsman spider species found in Wyoming, though they appear large and intimidating, are completely nonvenomous to humans. Whip scorpions and pseudoscorpions look vaguely scorpion-like but are harmless and rarely encountered. If you see an arachnid in Wyoming that concerns you, it is almost certainly one of these beneficial species. For detailed identification and information, readmore on Scorpion in Wyoming.

Frequently Asked Questions

**Are scorpions deadly?** Scorpions deliver stings, not bites, and most North American species cause only mild effects similar to a wasp sting. Even the most dangerous North American scorpion causes death only rarely, particularly with prompt medical care.

**How common are scorpion stings in Wyoming?** Scorpion stings do not occur in Wyoming because scorpions do not inhabit the state. This is the most important answer.

**What attracts scorpions to a house?** Scorpions seek dark, cool hiding spots and hunt insects and small prey. In regions where scorpions live, homes with foundation cracks and gaps are more vulnerable to accidental entry.

**What should I do if I see one?** If you encounter a scorpion while traveling in the Southwest, leave it alone and back away slowly while remaining calm. Do not attempt to capture or handle it. Call Poison Control at 1-800-222-1222 if concerned. See ourWyoming wildlife guide.
