Tarantula hawk wasps are large, solitary spider wasps with metallic blue-black bodies and bright orange (sometimes black) wings. In Oklahoma they’re most common in the western and southwestern parts of the state, where they hunt the Oklahoma brown tarantula from early summer into early fall. They look alarming and their sting is famously painful, but they don’t defend nests, don’t swarm, and almost never sting unless they’re stepped on, grabbed, or trapped.
For non-aggressive wasps I've had great luck spraying nests with this Spectracide wasp remover in the evening. For a nest up high in an eave, soffit, or tree, this Gotcha pole adapter clamps onto the can so you can spray from the end of an extension pole and treat the nest from 10+ feet away instead of standing right under it. And for anything aggressive I wear this ridiculous-looking upper torso beekeeping suit and keep my distance. It seems silly, but trust me, I learned the hard way.
Oklahoma sits near the eastern edge of tarantula hawk country, which is why many residents are surprised to see one. If you’ve just spotted a huge, slow-flying wasp with glowing orange wings working the flowers in your yard, this guide will help you confirm what it is and decide what (if anything) to do about it.
Quick answers for Oklahoma homeowners:
“Tarantula hawk” is the common name for large spider wasps (family Pompilidae) in the genus Pepsis and the closely related genus Hemipepsis. Several Pepsis species occur in the southern and southwestern United States, and a few reach into Oklahoma. Telling the individual species apart usually requires a specimen and a key, but for a homeowner the important point is that they all look and act much the same.
Like other spider wasps, tarantula hawks are solitary. There’s no colony, no queen, and no shared nest to protect. Each female works alone, and males don’t sting at all. That’s the main reason they’re so much less of a problem than social wasps like red wasps or yellow jackets, which will defend a nest in numbers.

Tarantula hawks are among the easiest wasps in the state to recognize once you know what to look for:
| Feature | What to look for |
|---|---|
| Size | Roughly 1 to 2 inches long; one of the largest wasps you’ll see in Oklahoma |
| Body | Shiny, metallic blue-black, slim and long-legged |
| Wings | Usually bright orange or rust-colored; some individuals have dark blue-black wings |
| Antennae | Dark, and in females often curled at the tips |
| Flight | Slow, low, and somewhat clumsy; legs often dangle in flight |
| On the ground | Walks quickly with wings flicking constantly while searching for spiders |
The orange wings are a warning signal. Predators that try a tarantula hawk learn quickly to avoid them, and the wasps behave accordingly: they move slowly and openly instead of hiding, because very few animals bother them. Roadrunners are among the few predators known to eat them.
Several other large wasps in Oklahoma get mistaken for tarantula hawks:
If you’re still not sure, our Oklahoma wasp species guide and giant wasps in Oklahoma article cover the state’s other large wasps.
Tarantula hawks follow their prey. In Oklahoma, that means the Oklahoma brown tarantula (Aphonopelma hentzi, also called the Texas brown tarantula), which lives in burrows in grasslands, prairies, and rocky hillsides.
You’re most likely to see tarantula hawks in:
They’re seen less often in heavily wooded eastern Oklahoma and in the densest parts of Oklahoma City and Tulsa, but they do turn up in suburban yards, especially near open land. For city-specific information, see our guides to wasps in Oklahoma City and wasps in Tulsa.
Adult tarantula hawks are warm-weather insects. In Oklahoma:
They’re active during the hottest part of the day and are rarely seen at dusk or at night. In the fall, Oklahomans often notice male tarantulas wandering across roads and driveways looking for mates. That’s a separate spider event, and it doesn’t mean tarantula hawks will show up at the same time. By October the wasps have usually finished for the year.
The name comes from how females provision their young:
Each female does this one spider at a time, so a tarantula hawk has no stockpile or colony to defend. That’s why they have no reason to attack people who come near.
Adult tarantula hawks don’t eat spiders themselves. They drink flower nectar, and they’re especially drawn to milkweed, a common plant in Oklahoma pastures and pollinator gardens. They also visit the flowers of soapberry, mesquite, and other native shrubs, and sometimes feed on fallen, fermenting fruit. While moving between flowers they carry some pollen, so they make a modest contribution to pollination. For more on this, see Are Wasps Pollinators?
The tarantula hawk has one of the most painful stings of any North American insect. Entomologist Justin Schmidt rated it a 4, the top of his sting pain index, and described it as immediate, excruciating, and debilitating.
The important context is this:
Most stings happen when someone:
Call 911 immediately if the person develops difficulty breathing, swelling of the face, lips, or throat, hives spreading beyond the sting site, dizziness, or a racing heartbeat. These are signs of anaphylaxis, which is a medical emergency regardless of which insect caused the sting. Anyone with a known sting allergy should use their prescribed epinephrine auto-injector right away.
For more detail, see our guides to normal wasp sting reactions, what to put on a wasp sting, and signs of an allergic reaction.
Children: The biggest risk is a child picking one up because it’s big, slow, and colorful. Teach kids that any large wasp with orange wings is “look, don’t touch,” and have them wear shoes in grassy areas during summer.
Dogs and cats: Pets get stung when they paw at or bite a tarantula hawk crawling on the ground. Expect yelping, pawing at the mouth, and drooling for a few minutes. Most pets recover quickly, but contact your veterinarian or an emergency vet right away if you see facial swelling, vomiting, weakness, collapse, or trouble breathing, or if the sting was inside the mouth or throat. See Dog Stung by a Wasp for a full guide.
Livestock and horses: Tarantula hawks pose no meaningful risk to livestock.
In almost every case, no. There’s no nest to remove, no colony to grow, and the wasps you see are passing through to feed or hunt. Spraying insecticide at individual wasps on flowers is ineffective and harms bees and butterflies using the same plants.
If tarantula hawks are making a part of your yard uncomfortable:
Because they’re solitary, the “seal cracks and keep food covered” advice used for social wasps doesn’t apply to tarantula hawks. They aren’t trying to nest in your house. For wasps that are building nests on your home, start with our wasp nest identification guide.
When to call a professional: If someone in your household has a severe sting allergy and you’re seeing large numbers of any stinging insect close to the house, contact a licensed pest management professional or your county OSU Extension office for advice. For tarantula hawks specifically, professional treatment is rarely necessary.
They’re fairly common in western and southwestern Oklahoma during summer and less common in the wooded east. Most residents see them only occasionally, usually on flowers or crossing open ground on hot days.
Yes. “Tarantula wasp” and “tarantula hawk” refer to the same group of large spider wasps. See our tarantula wasp homeowner guide for more.
No. Tarantula hawks don’t chase people and don’t defend territory. If one seems to follow you, it’s almost certainly flying past to a flower or searching the ground for spiders.
Not in people without an allergy. The venom is not considered dangerous despite the intense pain. As with any stinging insect, someone with a severe allergy can have a life-threatening reaction and needs emergency care.
No. Each female provisions one tarantula per egg, and tarantula and tarantula hawk populations have coexisted for a very long time. They’re both normal parts of Oklahoma’s prairie ecosystem.
The tarantulas you see crossing Oklahoma roads in September and October are mostly adult males searching for mates. By then, most adult tarantula hawks have finished their season. Females mostly hunt in summer.
Tarantula hawk wasps are among Oklahoma’s most striking insects: big, metallic, orange-winged, and armed with one of the most painful stings in North America. They’re also among the least aggressive. They don’t build nests on homes, don’t defend territory, and sting only when handled or stepped on. For most Oklahoma homeowners, the right response is to recognize them, teach kids and pets to keep their distance, and let them get on with their summer.
