STINGING INSECT GUIDE

Mexican honey wasp

Identification, local timing in San Antonio and the Hill Country, risk profile, and exactly how we treat it.

Scientific name: Brachygastra mellifica (Say, 1837) Common names: Mexican honey wasp, honey wasp; Spanish: "Panal Miniagua"; Popoluca: "Cuchii" Family: Vespidae (subfamily Polistinae) Status in the San Antonio / Boerne corridor: This wasp is native to Mexico and Central America. It's made its way into South Texas and is now expanding northward. We've noticed it's becoming more common in Bexar County and along the southern edge of the Hill Country.

At a glance #

Why this species matters #

The Mexican honey wasp is a wasp that does not behave like a wasp. Its biology defies what we typically expect from other vespid wasps in Texas.

• It stores honey in its nest. No other social wasp in North America does this in any significant amount.
• It feeds its larvae on honey and pollen like a bee, unlike other paper wasps that feed on chewed insect prey.
• It maintains perennial colonies that can last for several years. Most social wasps here die off in winter, but Mexican honey wasps keep their colonies alive.
• It is the only honey-storing wasp species in the entire United States.
• It has been eaten as food by indigenous peoples of Mexico for centuries — both the honey and the larvae are consumed.
• It has expanded its range into South Texas only in the last 50 years and is continuing to move north.

In the San Antonio to Boerne area, we've been getting more calls about Mexican honey wasps. They may look small and harmless, but those barbed stings pack a punch. These wasps form perennial colonies and their range is spreading fast. We're seeing them pop up on both residential and commercial properties where they weren't an issue just a generation ago.

Identification #

Small wasp with a black body and creamy-yellow banding. It's faintly hairy, which is unusual for wasps, but this hairiness helps them be effective pollinators.

The best way to identify Brachygastra is by looking at the abdomen shape. Their abdomens are short, broad, and nearly flat — which is fitting since the name means "short belly." Often, the abdomen is almost as wide as it is long. The scutellum, a plate behind the thorax, is high and angular, sometimes sticking out over the metanotum. These details make them easy to tell apart from other small Texas wasps.

One identification pitfall to note: there's a solitary vespid wasp species that looks almost identical to Brachygastra mellifica. The best way to tell them apart is the petiolate abdomen. Mexican honey wasps have a "wasp waist," but their petiole is short and nearly vertical, making it hard to spot in live specimens. In practice, the nest is a more reliable identifier than the wasp itself. If you see a large gray paper nest in a tree canopy with a small entry hole, and small black-and-yellow wasps buzzing around in South or South-Central Texas, it’s B. mellifica almost every time.

Biology and behavior #

A wasp that lives like a bee #

Mexican honey wasps, or Vespa mexicana, fill a role similar to honey bees. They form large, long-lived colonies, store honey, and collect pollen. Their hairy bodies help with pollination, but they didn't get there the same way. These paper wasps evolved into bee-like creatures on their own.

The closest example is convergent evolution. Brachygastra mellifica and Apis mellifera (the European honey bee) aren't closely related at all — they're in different families that split over 100 million years ago. However, they've developed strikingly similar biological strategies through entirely separate evolutionary paths. Recent research on gut microbiomes shows this clearly: Mexican honey wasps, like honey bees, host specific bee-like gut bacteria, while their nearest paper wasp relatives do not. Their honey-feeding habits have influenced both groups in similar ways at the cellular level.

Diet — honey wasps actually eat honey #

Workers search for nectar from many flowers like mesquite, sunflower, cenizo, mistflower, frostweed, retama, and huisache. They also gather honeydew from aphids and psyllids, which is a behavior you’d usually expect from ants. The nectar they collect gets processed in the nest and stored as honey, similar to how honey bees do it.

Workers also hunt small insects like flower-mining beetle larvae, weevil larvae, and small moth caterpillars, which they sometimes bring back to the nest. Here’s where it gets interesting: the larvae are fed primarily honey and pollen, not chewed insect protein. This sets them apart from other social wasps in the U.S. Every other paper wasp, yellowjacket, and hornet relies on insect prey for their larvae. Only Brachygastra uses a diet of honey and pollen like bees do.

This change in diet helps explain why wasp colonies have a certain structure. Wasps that rely on insect prey can only survive when those insects are plentiful. Once winter hits, their food source vanishes, and the colony struggles to make it. On the other hand, honey-storing wasps can gather food during good times and get through the tough months. It’s the same approach that helps honey bee colonies survive all year long.

The honey itself #

The honey from Mexican honey wasps is really good honey. Tests show that the glucose and fructose levels in B. mellifica honey stack up well against mesquite honey from honey bees, according to Penn State Extension. The taste depends on the flowers the wasps visit, and these often overlap with the plants that honey bees forage on in the same areas.

In Mexico, especially in Jalisco, honey from the honey bee is harvested and even sold commercially. Indigenous communities have been collecting B. mellifica honey for centuries. Early records from Mexico and Brazil clearly identify this insect — its unique paper nest stands out from the nests of stingless bees, which are the only other native source of honey historically available.

Cultural significance — Cuchii and Panal Miniagua #

The Popoloca people in Los Reyes Metzontla, Mexico, enjoy both the honey and larvae of Brachygastra mellifica. Locally, it’s known as "Panal Miniagua" in Spanish and "Cuchii" in the Popoloca language. Their diet features at least 17 different insect species, with B. mellifica being a favorite. They eat it year-round, but they follow a specific lunar schedule for harvesting. The wasps and their honey are collected when the moon is in its last quarter to waning gibbous phases.

This is one of the better-documented examples of how people have used a wasp species for food and sweetener for a long time. This practice goes back to before European honey bees were brought to the Americas.

Perennial colonies — the unusual lifecycle #

Most social wasp colonies in the U.S. only last a year. A lone mated queen makes it through the winter, starts a new colony in spring, and builds it up over the summer. By late summer or fall, she produces new reproductives, but when frost hits, she and all her workers die off.

Mexican honey wasp colonies don’t abandon their nests easily. A single colony can persist for several years, staying put in the same nest while workers come and go. They keep reproducing, which allows the colony to thrive. This is enabled by:

• Honey stores help the colony survive when foraging becomes tough.
• The mild winters of South Texas mean freezes are rare, so bees can stay active year-round.
• New nests get started by swarming — a queen takes some workers to set up a new colony, just like honey bees do — instead of queens overwintering alone.

Within a single nest, you might find multiple queens living together (that's called polygyny), and all of them help with laying eggs. This is a bit unusual since most paper wasps are strictly monogynous, meaning they only have one queen per nest.

Why they are moving north #

Mexican honey wasps have been spotted in South Texas for only about 50 years. Their range is creeping northward, and a few things are probably driving this expansion:

• Climate change — Milder winters in Central Texas let perennial colonies survive further north with each passing decade.
• Drought-tolerant landscape plants — Many popular Hill Country xeriscape plants like cenizo, salvia, mistflower, and native sages are fantastic B. mellifica nectar sources.
• Reduced freeze frequency in San Antonio — The historic average winter low temperatures have gone up, helping perennial colonies thrive in areas where they couldn't before.
• Habitat continuity — The brush-country habitat that B. mellifica prefers stretches from South Texas up the Rio Grande corridor and into the southern Hill Country brush zones.

Range expansion like this isn't new. The 1994 paper by Sugden and McAllen in the Journal of the Kansas Entomological Society laid down the initial range data for this species in the lower Rio Grande Valley. Since then, I've noticed sightings creeping steadily northward over the last thirty years.

The sting — barbed, like a bee #

Here is where the bee-mimicry stops being charming. The Mexican honey wasp sting is barbed. When a worker stings a human or another large animal, the stinger breaks off and stays in the wound, just like a honey bee sting. The wasp dies soon after that.

Unlike honey bees, Mexican honey wasps can sting multiple times before their stingers pull free. They don’t just sting once; other workers join in the attack. The barbed stings get stuck in the wound and keep pumping venom, which makes a disturbance to their nest far more dangerous than you'd think from their small size.

Workers are often called "mild-mannered by vespid wasp standards" while foraging, and that’s pretty accurate. I've seen them on flowers, and they usually won’t bother you. But get too close to their nest, and you'll see a different side. They defend fiercely, and their sting is no joke—it's hot and intense. If you get stung, you need to remove the stinger quickly to stop the venom from pumping in. The best way is to scrape it out, similar to the credit card technique recommended for honey bee stings.

Local context — South-Central Texas and the southern Hill Country #

Mexican honey wasps are everywhere in South Texas, from the Rio Grande Valley to the Brush Country and Coastal Bend. I've seen them pop up more and more throughout Bexar County, and they’re starting to show up in greater numbers in the southern Hill Country, too. According to Penn State Extension, this range expansion is part of their natural spread.

Where we see them locally:

• Southern Bexar County — This area, south of Loop 410, has brushy spots near Calaveras Lake, Mitchell Lake, and the southside greenbelt corridors. We're seeing established and increasing activity here.
• Southside San Antonio — Areas like Southtown, Mission Trail, and the older neighborhoods around the Spanish missions are experiencing recurring service calls, especially with mature mesquite trees.
• East San Antonio brush corridors — The IH-10 East corridor toward Seguin has remnant brush habitat that pushes into developed areas.
• Central San Antonio — We're noticing these pests more often, with confirmed nests in places like the Stone Oak live oak canopy, Alamo Heights, and established areas in Olmos Park.
• Boerne and Bergheim — This area is at the current northern leading edge. We've confirmed nests within Boerne city limits in recent years; it would have been a big deal a decade ago, but it’s now becoming routine.
• Helotes / Government Canyon — The brush-country habitat here is ideal for B. mellifica.
• Spring Branch / Bulverde — We’re seeing occasional nests, and the range expansion is still ongoing.

Homeowners in southern San Antonio or southside Boerne often spot "small bees" buzzing in and out of a hole in the canopy of a large mesquite or live oak. The activity doesn't stop, even in winter when "bees" are usually dormant. If you look up, you might see a gray-brown paper nest, sometimes the size of a soccer ball or bigger, tucked away in thick foliage, often 8 to 25 feet off the ground.

Risk to humans and pets #

Moderate to high aggression occurs if you get too close or disturb a nest. If you keep your distance, the risk is low.

The combination that makes Mexican honey wasps a real concern:

• Established nests can house thousands of workers in these perennial colonies.
• When defending their colony, many workers will attack at the same time.
• Their barbed stings keep pumping venom even after they’ve detached.
• Nests are usually tucked away in dense tree canopies, which can lead to accidental disturbances during tree work, pruning, or recreational activities.

Foraging workers are not aggressive. The danger is entirely localized to the nest. Common scenarios for stings include:

• Tree pruning or trimming can accidentally reveal a nest.
• After storms, removing tree branches might expose hidden nests.
• Kids climbing trees are often curious about nests.
• Utility crews working near unmarked nests can stir things up.
• Pets, especially dogs, can disrupt low-hanging branches and nests.

Allergic people need to be cautious around stinging insects. A single Mexican honey wasp can sting multiple times, and if someone accidentally disturbs a nest, they could get hit with 30 to 100 stings in just a few seconds, according to CDC. That’s a serious risk for anyone with a severe allergy to Hymenoptera.

Treatment approach #

• Identification first. We need to confirm the species — look for small, honey-bee-sized wasps with banded abdomens entering a paper nest high in the tree canopy. Don’t mix them up with bees in the wall or paper wasps in the eaves; those are different issues.
• Survey the location. Mexican honey wasp nests can be found anywhere from 8 to 30 feet up in dense canopies, often hidden behind leaves. The nest is usually bigger than what you can see from the ground.
• Protective equipment is mandatory. You’ll need a full bee suit with a veil, sealed gloves, and sealed boots. This isn’t the time for that lightweight wasp suit meant for paper wasp removal.
• Treatment timing: The best time to treat is at dusk or pre-dawn when most of the workers are inside the nest. Cooler morning temps can slow their defensive response.
• Treatment method: Apply insecticide directly to the nest entry point using extension equipment. Give it 24-48 hours for the treatment to spread through the colony before you attempt to remove the nest.
• Physical removal of the nest is essential. Unlike annual wasps, leaving an abandoned Mexican honey wasp nest can cause problems. Even after treatment, leftover queens or workers might try to come back. Plus, honey stored in the nest can attract other pests like ants, wax moths, and even raccoons or opossums.
• Site monitoring for 30 days after treatment is a good idea to make sure there’s no recolonization.
• For nests on commercial properties, schools, or shared spaces — it’s crucial to clearly mark the area and notify work crews and grounds staff. Mexican honey wasp nests can be tough to spot from the ground.

For nests that are truly out of reach, like those high in trees or on unmaintained land away from regular activity, we often take a similar approach as we do with baldfaced hornet nests: leave them alone and mark the spot. However, B. mellifica colonies are different. They stick around year after year and won't die off with the frost. This means these nests can get bigger over multiple seasons instead of just disappearing each year.

Odd, funny, and genuinely true #

• Mexican honey wasps are pollinators of avocado crops in Mexico. Research documented in agricultural literature shows that B. mellifica is one of the primary pollinators of commercial avocado orchards in parts of Mexico. The fuzzy body that allows them to carry pollen — unusual among wasps — makes them genuinely effective pollinators of orchard crops.
• The honey contains comparable sugars to honey bee mesquite honey. Glucose and fructose ratios in B. mellifica honey match honey bee honey produced from the same mesquite floral source. If you tasted both honeys side by side without knowing which was which, you would have difficulty distinguishing them by flavor alone.
• **There are 12 species in the genus Brachygastra, ranging from southeastern Arizona and South Texas to northern Argentina. Only B. mellifica has crossed into the United States.** The genus is overwhelmingly tropical and subtropical.
• **Two other Brachygastra species** (B. lecheguana and B. scutellaris) also store significant honey, but in smaller quantities and not in the United States.
• Woodpeckers and opossums attack the nests for the honey. Both golden-fronted woodpeckers and opossums have been observed dissecting Mexican honey wasp nests to access the stored honey and brood. This is a meaningful predation pressure that Mexican honey wasp colonies have evolved defensive strategies to counter, including preferentially nesting in dense, hard-to-access canopy locations.
• **The scientific name "mellifica" comes from the Latin for "honey-making"** — the same root used in Apis mellifera, the European honey bee. Both species were named for the same trait by independent observers.
• The Popoloca harvest follows lunar phase. Honey is collected when the moon is between last quarter and waning gibbous. The ecological reason for the timing is not entirely clear, but it has held as a cultural practice for generations.
• ***Polistes annularis* is the only other Texas paper wasp known to store honey** to overwinter, and even then in small quantities. Mischocyttarus species (also paper wasps) store honey short-term. The sustained, perennial honey storage of Brachygastra is unique among American social wasps.
• Trophallaxis — mouth-to-mouth food transfer between workers — has been observed on the surface of B. mellifica nests. A returning forager regurgitates a drop of nectar to a responsive nestmate, who processes it. This is the same liquid-food sharing system honey bees use, and it has independently evolved in Mexican honey wasps as part of the honey-storage system.
• The species was first formally described by American entomologist Thomas Say in 1837, based on Mexican specimens. Say is one of the founding figures of American entomology, and B. mellifica was among the species he described from material collected during the early 19th century explorations of the American Southwest.
• Diogmites angustipennis, a robber fly, preys on Mexican honey wasps — one of the few documented cases of a fly preying on a vespid. Robber flies are aggressive aerial predators that ambush flying insects, and they apparently overcome the wasps' defenses through ambush attack.
• Range expansion of Mexican honey wasps into South Texas was documented as starting in the 1970s. Within human memory — within the working career of senior pest control operators currently active in San Antonio — the species went from "not present in Texas" to "expanding into the Hill Country." This rate of range shift is documented climate-change-associated movement happening in real time.

Common questions customers ask #

• A Mexican honey wasp (Brachivelea caudata) is a type of wasp that can make honey, but it’s not the same as a honey bee. They’re smaller, usually around ¾ inch long, and have a distinctive yellow and black coloration.
• Yes, there is a wasp that makes honey — the Mexican honey wasp. But don’t expect the same kind of honey you'd get from honey bees. Their honey is often less sweet and more watery.
• The Mexican honey wasp is smaller than a honey bee and has a different nesting behavior. Honey bees are more social and create large hives, while Mexican honey wasps build smaller nests and are more solitary.
• Mexican honey wasps can be dangerous if provoked. They can sting multiple times, and their sting is painful, though not typically life-threatening unless you have an allergy.
• Yes, Mexican honey wasps are indeed in San Antonio and surrounding areas. We’ve pulled plenty of nests from homes in neighborhoods like Alamo Heights and Stone Oak.
• A wasp nest in your tree during winter could mean it was abandoned or that the colony is dormant. Most wasps die off when cold weather hits, leaving only the fertilized queens to survive until spring.
• There are reports of Mexican honey wasps spreading into the Texas Hill Country. Areas like Boerne and Fair Oaks Ranch have seen an increase in sightings.
• You can eat Mexican honey wasp honey, but it's not common. The taste can be quite different from the honey you're used to, and it's not typically harvested for human consumption.

We pulled information from various sources for this guide. This includes the Wikipedia page on Brachygastra mellifica, which cites the foundational study by Sugden & McAllen in the Journal of the Kansas Entomological Society from 1994. We also looked at the Texas Entomology website, BeesWiki, and Bug Eric's coverage by entomologist Eric Eaton. There’s even recent peer-reviewed work on the independent evolution of honey-feeding gut microbiomes in B. mellifica (bioRxiv 2024 / PMC12607865). The Beeville Bee-Picayune provided insights into South Texas natural history, along with historical references to how the Popoloca culture used this species. Documentation of its range expansion shows decades of observation by entomologists in South Texas.

Frequently asked questions #

How can I identify a Mexican Honey Wasp? #

Mexican Honey Wasps are about half an inch long and have a distinctive yellow and black pattern on their bodies. They are often confused with yellowjackets but are generally more slender and have a more elongated shape.

What kind of behavior do Mexican Honey Wasps exhibit? #

Mexican Honey Wasps are known for being social and building large nests, often in trees or under eaves. They can be aggressive, especially when their nest is disturbed, so it's best to keep your distance.

Are Mexican Honey Wasps a significant risk in San Antonio? #

While they can be aggressive, the risk they pose largely depends on proximity to their nests. If you inadvertently disturb a nest, they may sting in defense, which can be painful and cause allergic reactions in some individuals.

When is the best time to deal with Mexican Honey Wasps in the Texas Hill Country? #

In our area, Mexican Honey Wasps are most active from late spring through early fall. This is when their populations peak, and you'll likely notice more activity around your home.

What treatments do you offer for Mexican Honey Wasp infestations? #

We provide professional removal services that focus on safely eliminating the nest and minimizing the risk of stings. Our treatments are typically scheduled for early morning or late evening when the wasps are less active, ensuring a safer process.
