Top 10 Most Painful Insect Bites and Stings

1. Bullet Ant

   

   Bullet ants are native to the rainforests of Central and South America. Their sting delivers poneratoxin, a neurotoxic peptide that interferes with nerve signaling. This sting is widely regarded as one of the most painful insect stings known.

   It's like being shot.

   Pure, intense, brilliant pain - like walking over flaming charcoal with a three-inch rusty nail grinding into your heel.

   It is indescribable pain, coming at you in waves of fury. It's like you're being engulfed in red-hot flames while being jabbed by dozens of spiky nails.

   That's why they're called bullet ants - because their sting is like being shot by a shotgun.

2. Warrior Wasp

   

   The warrior wasp, Synoeca septentrionalis, is native to Central and South America. It is known for an intensely painful sting that ranks very high on the Schmidt sting pain index. Colonies build large exposed paper nests that often resemble inverted cones and are aggressively defended.

   Torture.

   You are chained in the flow of an active volcano.

3. Velvet Ant

   Despite the name, the velvet ant is actually a wingless female wasp. Velvet ants are known for their extremely tough exoskeleton and a sting that is considered among the most painful of any insect. Males are winged and lack a stinger, while females are wingless and brightly colored.

   Explosive and long-lasting. You sound insane as you scream. It's like hot oil from deep frying spilling all over your hand.

   Worse than any wasp sting, and I've been stung by many. I wanted to amputate my thumb.

4. Tarantula Hawk

   

   Tarantula hawks are large wasps that prey on tarantulas, paralyzing them with a sting before laying an egg on the spider. Their sting is considered one of the most painful insect stings but is rarely life-threatening to humans. These wasps are found primarily in the Americas, with related species occurring in other regions.

   Blinding, fierce, shockingly electric.

   A running hair dryer has been dropped into your bubble bath.

   May or may not be voting because of the *shivers* cazadores in Fallout: New Vegas.

5. Red Paper Wasp

   

   Red paper wasps belong to the genus Polistes and are commonly found in the southern United States. They construct umbrella-shaped nests made from chewed wood fibers mixed with saliva. Their sting is used for defense and prey capture and can cause immediate pain and swelling.

   Caustic and burning, with a "distinctly bitter aftertaste." It's like spilling a beaker of hydrochloric acid on a paper cut.

6. Yellow Jacket

   

   Yellow jackets are predatory social wasps in the genera Vespula and Dolichovespula. They live in large colonies and are known for aggressively defending their nests. Their smooth, non-barbed stinger allows them to sting repeatedly.

   Hot and smoky, almost irreverent.

   Imagine W.C. Fields extinguishing a cigar on your tongue.

7. Trap‑jaw Ant

   Trap-jaw ants are known for their mandibles, which can snap shut at extremely high speeds. They use these mandibles for hunting, defense, and even as a means of propulsion by snapping against the ground. Some species can also sting, and the venom can cause sharp pain and localized swelling in humans.

   It's instantaneous and excruciating.

   As if a rat trap snapped on your index fingernail.

8. Executioner Wasp

   

   The executioner wasp, Polistes carnifex, is native to Central and South America. It is among the largest species of paper wasp. Its sting has been reported to be intensely painful and can cause prolonged discomfort.

   This is considered the worst and most painful insect sting ever - worse than the bullet ant or Asian giant hornet. It's been described as feeling like your skin and flesh are being ripped apart.

   It's listed here twice, and no wonder - it's the most painful insect sting known to man. They say it feels like burning, searing pain, like being submerged in lava. Incredibly painful.

   This should be ranked on the sting pain index.

9. Asian Giant Hornet

   

   The Asian giant hornet, Vespa mandarinia, is the world's largest hornet species. It is native to East and Southeast Asia and is known for coordinated attacks on honey bee colonies. Its sting delivers potent venom that can cause severe pain and tissue damage.

   It's like a narrow, hot nail being driven into your body.

10. White‑Faced Bee

    If this is the same critter as the White-Faced or Bald-Faced Hornet, it's one of the angriest, nastiest, and most persistent little hellhounds on the planet. Piss them off, and they'll chase you all the way to Hades.

    It's basically the Bald-Faced Hornet, and its sting is like getting your hand mashed in a revolving door.

The Newcomers

    Assassin Bug

    

    They have powerful saliva that causes extreme pain, more than most things on this list. They're also responsible for Chagas disease, which kills 12,000 people every year.

12. ?

    Southern Flannel Moth Caterpillar

    

    A caterpillar has six true legs and ten false legs, so it counts as an insect as well. It's the worst pain you could get from an animal, though.

The Contenders

13. Red Fire Ant

    

    Red fire ants, Solenopsis invicta, are an invasive species originating from South America. They form large colonies and aggressively defend their nests when disturbed. Their stings inject alkaloid venom that causes a burning sensation and characteristic pustules.

    I remember once when I was a little kid, on a summer day, I fell into a fire ant hill. The ants were biting my leg, and it was super painful. I remember it felt like someone was pinching me very hard or deliberately hurting me.

    I stepped on a fire ant hill and didn't know it. It was super painful.

14. Deer Fly

    

    Deer flies are blood-feeding insects of the genus Chrysops. They use scissor-like mouthparts to cut the skin and lap up blood rather than piercing it. Their bites are painful and can result in prolonged irritation or swelling.

    These flies are some of the most annoying, persistent, and painful flies around. Never mind a mosquito - these things really cut through the skin and feed on blood like vampires. I hope you don't get cursed.

    I've been bitten by these flies. It feels like a flu shot. They literally rip through the skin and drink blood, but rarely do they cause sickness.

    Imagine someone dropped a cigarette on you while you were biking.

15. Honey Bee

    

    Honey bees are eusocial insects known for their role in pollination and honey production. Workers possess a barbed stinger that detaches after stinging mammals, which results in the bee's death. The venom contains melittin, a compound responsible for pain and inflammation.

    This is a sting we're very familiar with. It's like a match covered in lye and sulfuric acid landed on your skin and burned it. But it's not as bad as some of the other insect stings out there.

    Burning and corrosive, but it's bearable. It's like a flaming match head lands on your arm and is first quenched with lye and then sulfuric acid.

    Today, while on vacation in Mexico, I was on the beach barefoot and stepped on a bee. It hurt badly, and I'm still sore where I got stung. I almost cried from the pain.

16. Fierce Black Polybia Wasp

    Like a ritual gone wrong. Satanic.

    The gas lamp in the old church explodes in your face when you light it.

17. Red‑Headed Paper Wasp

    The red-headed paper wasp, Polistes canadensis, is distributed throughout Central and South America. It is a eusocial species with colonies that often nest in sheltered locations such as under eaves or branches. Its sting is used for defense and is considered painful to humans.

    Immediate, irrationally intense, and unrelenting. This is the closest you will come to seeing the blue of a flame from within the fire.

18. Polybia Wasp

    Polybia is a genus of eusocial wasps found in Central and South America. These wasps are known for forming large colonies and building complex paper nests. Several species in the genus are noted for delivering painful defensive stings.

    This is referring to the Ferocious Polybia Wasp, which doesn't come close to the pain of the Fierce Black Polybia Wasp.

    Like a trick gone wrong, your butt is a target for a BB gun.

    Bull's-eye!

19. Argentine Harvester Ant

    The Argentine harvester ant, Pogonomyrmex mendozanus, is native to South America. It collects and stores seeds as its primary food source. Its sting is considered medically significant due to the potency of its venom.

    A ferocious pang, and it lasts 12 hours.

    Flesh-eating bacteria dissolve your muscles, one by one.

20. Harvester Ant

    Harvester ants belong to the genus Pogonomyrmex and are found throughout the Americas. They are primarily granivores, collecting and storing seeds in underground nests. Their sting can cause intense pain and may trigger allergic reactions in sensitive individuals.

    Bold and unrelenting.

    Somebody is using a power drill to remove your ingrown toenail.

21. Maricopa Harvester Ant

    The Maricopa harvester ant, Pogonomyrmex maricopa, inhabits the southwestern United States. It is regarded as having one of the most toxic insect venoms relative to body weight. Multiple stings can cause intense pain and, in rare cases, serious systemic reactions.

    It's like you've spent 8 hours using a drill to get rid of your ingrown toenail, and then it gets wedged in your toe.

22. Glorious Velvet Ant

    The glorious velvet ant, Dasymutilla gloriosa, is a species of wasp found in the southwestern United States. Females are wingless and covered in dense red-orange hair, while males have wings and a different coloration. The female's sting is extremely painful, which has earned velvet ants the nickname "cow killer."

    Instantaneous, like the surprise of being stabbed.

    Is this what shrapnel feels like?

23. Southern Fire Ant

    

    It happens on the third day, as you reach for the light switch, and you're wondering:

    When will you ever learn?

24. Unstable Paper Wasp

    

    Like a dinner guest who stays too long, the pain drones on.

    A hot Dutch oven lands on your hand, and you can't get it off.

25. Giant Paper Wasp

    

    There are "gods," and they do throw their thunderbolts.

    Poseidon/Neptune has rammed his trident into your chest.

    I got stung by a wasp today while on vacation. It hurt so badly, and I'm still sore where I got stung. I was stung five times by the same wasp and had to get out of the area. I cried in pain.

26. Yellow Fire Wasp

    

    An odd, distressing pain.

    Tiny blowtorches kiss your arms and legs.

27. Honey Wasp

    

    Spicy, blistering.

    A cotton swab dipped in habanero sauce has been pushed up your nose.
