Mexican Honey Wasp: The Gray Paper Ball Nest in Your Texas Tree
A gray, ball-shaped paper nest tucked into the canopy of a tree or shrub may well be the work of Mexican honey wasps: small, dark wasps that make and store honey. TAIS describes them as not very aggressive, and AgriLife says the nest usually doesn't need to come down. If it hangs where you need to prune, build or let kids play, have a professional with protective gear handle it.

Bee or wasp? #
Wasp, despite the honey. The nest gives it away: it's made of paper, not wax. AgriLife's honey bee bulletin draws the line clearly, with honey bees building comb from wax and social wasps building nests from paper.
The honey is real, though. AgriLife's E-346 bulletin singles this out as the one wasp that stores honey. Wizzie Brown, an AgriLife Extension program specialist, writes that the wasps make and store it much like honey bees do, to carry the colony through winter.
How to recognize the wasp #
Mexican honey wasps are small. Both TAIS and E-346 say they are smaller than a honey bee, and Brown puts them at roughly 1/4 to 1/3 inch.
The color descriptions don't quite match:
- TAIS: nearly all black, and not very hairy.
- Brown: a dark head and thorax, rusty wings, and a teardrop-shaped abdomen striped in yellow and black.
Either way, you're looking for a small, dark, fairly smooth wasp, not a fuzzy bee and not a large black-and-white hornet.
How to recognize the nest #
TAIS says the nest is made of paper and built in trees and shrubs, and AgriLife describes it in the canopy. Brown gives more detail: around 18 inches, shaped anywhere from a basketball to a football, and often placed high where it won't get bumped.
Other nests it can be confused with:
- Baldfaced hornet: also gray paper in a tree, but shaped like an upside-down pear with the entrance at the bottom, and built by 3/4-inch black-and-white wasps.
- Honey bee colony: wax comb, usually hidden in a cavity such as a wall or hollow tree. See our European honey bee and Africanized honey bee guides.
- Paper wasps: an open comb with no outer shell around the cells.
Life inside the colony #
Brown's notes paint the picture of a big, long-lived household:
- 3,000 to 18,000 wasps in a single nest
- more than one queen per colony
- several colonies clustered together in some areas
- a nest that stays in use for about 3 years before the wasps abandon it
Where they live #
AgriLife's 2021 publication listing gives the range as Texas to Nicaragua. Brown adds that within North America the wasp is found in Arizona and Texas.
That is as specific as the sources get. None of the AgriLife or TAIS material we checked names Texas counties or says whether the range is shifting. So we won't tell you how common these wasps are around San Antonio. If you find a nest, a photo showing both the nest and the wasps is the quickest route to a firm ID.
Is there a season for them? #
None of the sources give a peak season. Because the colony stores honey to get through winter and a nest lasts about 3 years, you could spot one in any month of the year.
Will they sting? #
Rarely, by most accounts. TAIS says these wasps are not very aggressive and often ignore people nearby, and E-346 calls them very docile. Brown adds the important caveat: females can sting, and they will if the colony is threatened or they are provoked.
The sources we rely on don't describe how painful the sting is, and none say the stinger stays in the skin, so we won't claim either. For any sting, CDC/NIOSH advice applies: wash the area, ice it and don't scratch, and get medical care right away for signs of a severe allergic reaction.
The good they do #
Brown describes Mexican honey wasps as pollinators that gather nectar and pollen to feed their young. The adults also eat other insects, especially Asian citrus psyllids when those are around. That's a fair reason to give these neighbors some room when you can.
Leave it, or have it removed? #
Leave it when:
- it's high in a tree or deep in a shrub that nobody trims
- people and pets don't regularly pass underneath
- you can simply route activity around it
E-346 says there is usually no need to remove the nest.
Have it removed when:
- you need to prune, take down or build near that tree
- it hangs over a play set, patio or path
- someone in the household has a venom allergy
Brown's advice for those cases is to call a professional with proper protective equipment, such as a bee suit.
Whatever you decide, don't:
- poke, shake or throw things at the nest
- take a pole saw or trimmer to the branch it's on
- assume it's a honey bee colony and call a beekeeper
Planning yard work around a nest #
Because Brown says these wasps sting when the colony is provoked, the risky moment is usually when someone works right next to the nest, not everyday life in the yard. A few habits help:
- Scan the canopy before anyone prunes, climbs or strings lights in a tree.
- If the branch holding the nest has to be cut, deal with the nest first.
- Tell family members and anyone working on the property exactly where it is.
- Keep ladders, pole saws and string trimmers away from that branch in the meantime.
Texas rules: why the honey bee laws don't apply #
Texas lets registered beekeepers collect, remove or destroy honey bees under Occupations Code §1951.056, and TAIS keeps a county list of beekeepers who do removals. The Mexican honey wasp isn't a honey bee, so by their own terms neither the beekeeper exemption nor the TAIS list covers it. We found no Texas rule written for this species.
How Pest Trappers handles Mexican honey wasp nests #
The technician starts by confirming what built the nest, since a baldfaced hornet nest or an exposed honey bee colony would call for a different plan. Next comes the question of whether the nest truly has to go. Often the honest answer is no.
If it does need to come down, you'll hear the options and what each involves, and any product used goes on according to its label. Pest Trappers LLC (TPCL #0887549) quotes after the inspection, so call for pricing. Town pages: San Antonio, Leon Springs and The Dominion, Helotes and Cibolo.
