How Fast Can Scorpions Move?

May 31, 2025

If you've ever flipped on a light and seen something scuttle under the couch, you know that scorpions can move disturbingly fast. But just how fast are we talking?

Scorpion Speed in the Real World

Most scorpions move at a walking pace of about 3 to 4 mph. That might not sound impressive until you realize that on their scale, it's like sprinting. When threatened, some species can dash even faster in short bursts—close to 8 to 10 mph.

That’s fast enough to cross a room in a few seconds. Especially in the dark, their quick movements can catch homeowners off guard.

Why Speed Matters in Scorpion Detection

Scorpions don’t just sit still waiting to be spotted. They're nocturnal hunters and like to stay hidden. Their quick, erratic movements make it hard to find them by sight alone—especially with a flashlight at 2 AM.

That’s where our Detectors come in. They scan for the faint green glow that scorpions give off under UV light, taking photos every second once it's dark enough. Even if a scorpion is only in frame for a moment, our system can catch it and alert you.

Where They’re Fastest

Scorpions tend to move fastest on smooth indoor surfaces like tile or hardwood. In Tucson homes, for example, they’ll often dart across kitchen floors or bathrooms, drawn to moisture. Outdoors, rocky or sandy terrain slows them down a bit.

Quick Tips to Limit Their Movement

The less hiding space and moisture they find, the less likely they are to stick around—or dart across your floor when you least expect it.

Scorpions might be fast, but they’re not faster than a well-placed Detector. Set yours up in scorpion-prone areas like garages, bathrooms, and under sinks to catch them in action before they become a real problem.

Frequently Asked Questions

What is the largest scorpion species?

The giant forest scorpion (Heterometrus swammerdami) from India can reach up to 9 inches (23 cm) in length, making it the world's largest.

Do scorpions avoid UV light?

Not much is known about why scorpions glow under UV light, but some theories suggest that although they can't see it, they can 'feel' it when it's bright. Our Scorpion Detectors emit just enough UV light to illuminate them, but not enough to make them avoid it.

Are all scorpions venomous?

Yes, all scorpions produce venom, which they use for hunting and defense. However, only about 30-40 species have venom potent enough to be dangerous to humans; most stings are comparable to a bee sting.
