If you live in Arizona, Texas, or anywhere else in the Southwest, spotting a scorpion isn’t rare. But when a sting happens, knowing which symptoms to watch for can make all the difference.

Mild vs. Serious Reactions

Most scorpion stings in the U.S. come from the bark scorpion, especially around Phoenix and Tucson. While many stings are no worse than a bee sting, some can trigger more dangerous reactions—particularly in young kids, older adults, and anyone with allergies.

Mild symptoms usually include:

These symptoms typically fade within a few hours.

Symptoms That Mean It’s Time to Get Help

There are a few red flags that suggest the venom is affecting your nervous system or triggering a more severe response. If you or someone near you shows any of these signs, don’t wait it out—get medical attention fast.

Call a doctor or go to urgent care if you notice:

When It’s an Emergency

In rare cases, especially with multiple stings or in sensitive individuals, scorpion venom can cause life-threatening reactions.

Call 911 if:

Keep Scorpions Out—Before They Sting

You can’t always prevent a sting, but you can drastically reduce the chances. In many Tucson homes, for example, scorpions sneak in through small cracks near baseboards or vents. Detectors like ours use UV light and image recognition to catch scorpions in the act—before you step on one barefoot at 2 a.m.

Bottom Line

If you’re stung and feeling okay, chances are you’ll be fine. But if symptoms go beyond pain and swelling—especially anything that involves the nervous system—it’s time to take it seriously.
