Mexican Honey Wasp Control in San Antonio, TX
If you've spotted a gray, papery ball the size of a football or basketball up in a San Antonio tree or shrub, with small dark wasps that seem to ignore you, you may be looking at a Mexican honey wasp nest. These are calm, honey-storing wasps, and AgriLife says there is usually no need to take the nest down. The exception is a nest where people have to prune, build, mow under or play; then it needs a professional in protective gear. Call or text (210) 281-1064 or book online if yours is in the way.
Three questions before you do anything #
Do they live around San Antonio? #
AgriLife describes the range as running from Texas south to Nicaragua, and Brown notes that within North America the species occurs in Arizona and Texas. None of the AgriLife or TAIS sources we rely on maps it by county or describes it spreading, so we can't tell you how common it is in Bexar County. What we can say is how to recognize the nest and what to do about it.
Park trees and backyard trees #
Brown says nests are often built high in trees and shrubs, where they won't be disturbed. Friedrich Wilderness Park, for example, is managed partly for the nesting of two endangered songbirds (City of San Antonio), and Phil Hardberger Park covers 311 acres on the north side. A paper nest overhead on a park trail is something to admire from the path, not to poke at.
At home the question is different. Think about the jobs that bring people close to the canopy:
- pruning or trimming branches;
- stringing lights or hanging a swing;
- roofing or gutter work next to an overhanging limb;
- kids climbing the tree.
If none of those apply, the nest can usually stay where it is.
A wasp with a pantry #
E-346, an AgriLife publication on bees and buildings, calls this the only wasp that stores honey. Brown explains that the colonies make and keep honey much as honey bees do, to carry them through winter. That has practical consequences:
- It doesn't die off in fall. Brown says nests last about three years before they're abandoned, so you may see activity in any month.
- It can be big. Brown counts 3,000 to 18,000 wasps per nest, with several queens, and notes that clusters of colonies are common in some places.
- It's useful. Brown describes the adults as pollinators that gather nectar and pollen for their larvae, and as predators of other insects, including Asian citrus psyllids when they're around.
Calm, until the nest is bumped #
TAIS says these wasps aren't very aggressive and often ignore people, and E-346 calls them very docile. Brown adds the important caveat: females can sting, and will to protect the colony or when provoked. None of our sources rate how painful the sting is. Treat any sting the usual way (wash, ice, don't scratch) and get emergency care for signs of a severe allergic reaction, as CDC advises for all stings.
When the nest has to go #
Brown's advice is direct: if these wasps need managing, call a professional who has proper protective equipment such as a bee suit. Don't knock the nest down with a pole or spray it from a ladder. Because this is a wasp, not a honey bee, the beekeeper exemption in Texas law and the TAIS beekeeper removal list don't apply to it by their terms.
How Pest Trappers handles Mexican honey wasps in San Antonio #
A technician confirms the ID from the ground, checks how close the nest is to doors, play areas and work zones, and tells you honestly whether it can stay.
