The Insect Sting Pain Scale: Schmidt’s Legendary Ranking Explained
Have you ever wondered just how much a sting really hurts? Is a bee sting worse than a wasp? Does a fire ant pack more punch than a paper wasp? And what on earth could possibly feel like “walking over flaming charcoal with a 3-inch nail embedded in your heel”?
Welcome to the world of the Schmidt Sting Pain Index: the most famous (and most bizarre) pain scale ever created.
Entomologist Justin O. Schmidt spent years deliberately getting stung by over 80 different insects, then poetically describing the agony on a scale from 1 to 4+.
The result is part science, part literature, and 100% unforgettable.
In this guide, we will walk through the scale, meet the insects that top the charts, and explore why some stings feel like mild annoyance while others feel like pure torture. Let us get into it carefully.
The Man Behind the Madness: Who Was Justin O. Schmidt?
Justin O. Schmidt, nicknamed “The King of Sting,” was an entomologist who dedicated decades to studying insect venoms.
Between 1973 and the 2010s, he let himself be stung by more than 80 species of ants, bees, and wasps, all in the name of science.
He did not just rate the pain with numbers. He wrote vivid, almost poetic descriptions, like comparing one sting to “a lover biting your earlobe a little too hard” and another to “blinding, fierce, shockingly electric.”
The result is the Schmidt Sting Pain Index, a scale that goes from 1 (barely noticeable) to 4+ (excruciating).

How the Scale Works
The Schmidt Sting Pain Index rates stings on a scale of 1 to 4:
- 1.0: Almost pleasant, mild, fleeting
- 2.0: Painful, like a familiar sting
- 3.0: Sharply and seriously painful
- 4.0+: Traumatically painful, pure agony
Schmidt used the honey bee sting as the anchor point: a solid 2.0. Everything else is compared to that baseline.
The Most Painful Stings on the Scale (Level 4+)
Only a handful of insects reach the terrifying 4.0+ level. Here are the top scorers:
| Insect | Pain Level | Schmidt’s Description |
|---|---|---|
| Bullet Ant (Paraponera clavata) | 4.0+ | “Pure, intense, brilliant pain. Like walking over flaming charcoal with a 3-inch nail embedded in your heel.” |
| Tarantula Hawk Wasp (Pepsis spp.) | 4.0 | “Blinding, fierce, shockingly electric. A running hair dryer dropped into your bubble bath.” |
| Warrior Wasp (Synoeca septentrionalis) | 4.0 | “Torture. You are chained in the flow of an active volcano. Why did I start this list?” |
Level 3 Stings: Sharply and Seriously Painful
These are intense but not quite apocalyptic:
- Paper Wasp: “Caustic and burning. Like spilling hydrochloric acid on a paper cut.”
- Fire Ant: “Sharp, sudden, mildly alarming. Like walking across a shag carpet and reaching for the light switch.”
- Yellowjacket: “Hot and smoky, almost irreverent. Imagine W.C. Fields extinguishing a cigar on your tongue.”
Level 2 Stings: Familiar and Painful
This is where most common stings land; the honey bee sting is the baseline here:
- Honey Bee: “The oven mitt had a hole in it when you pulled the cookies out of the oven.”
- Bald-Faced Hornet: “Rich, hearty, slightly crunchy. Similar to getting your hand mashed in a revolving door.”
Level 1 Stings: Barely Noticeable
These are the gentle ones:
- Sweat Bee: “Light, ephemeral, almost fruity. A tiny spark has singed a hair on your arm.”
- Fire Ant (small species): “Sharp, sudden, mildly alarming.”

The Insect Sting Pain Scale (FAQs)
What is the Most Painful Insect Sting according to the Schmidt Scale?
The bullet ant (Paraponera clavata) tops the scale at 4.0+, described as “pure, intense, brilliant pain.”
Who Created the Schmidt Sting Pain Index?
Entomologist Justin O. Schmidt, who endured over 1,000 stings to create the scale.
Is the Honey Bee Sting the Baseline for the Scale?
Yes, Schmidt rated the honey bee sting as a solid 2.0, the reference point for all other ratings.
Which Sting is Worse: Tarantula Hawk or Bullet Ant?
The bullet ant is rated higher (4.0+) than the tarantula hawk (4.0), though both are excruciating.
Are all Insect Stings rated on the Schmidt Scale?
No, the scale focuses on Hymenoptera (ants, bees, and wasps). Other insects like true bugs or beetles are not included.
Conclusion
Justin Schmidt’s pain index is more than just a quirky list; it is a testament to the incredible diversity of insect venoms and the evolutionary creativity behind them.
From the gentle nip of a sweat bee to the apocalyptic agony of the bullet ant, each sting tells a story about survival, defense, and adaptation.
So next time you feel a sting, take a second to appreciate the science behind the pain, and maybe give that little insect a respectful nod (from a safe distance). After all, in the world of insects, pain is just another way of saying “leave me alone.”
What about you? Have you ever experienced a sting that felt like it belonged on the Schmidt scale? Which one do you think sounds the worst? I would love to hear your story.
