Saw a Giant Hornet in Stone Oak? What It Most Likely Is
No one has ever confirmed an Asian giant hornet (renamed the northern giant hornet) anywhere in Texas, so the monster wasp in your Stone Oak yard is almost certainly a local species. In summer the likeliest match is a cicada killer digging in a sunny lawn; on flowers it may be a tarantula hawk; and a big orange wasp near a ground nest is probably a yellowjacket queen. When there is an actual nest by the house, text or call (210) 281-1064, or schedule through the booking page.
Where the real one turned up, and where it went #
According to the Texas Apiary Inspection Service, there is currently no giant hornet population in this state (TAIS). In North America it was detected only in British Columbia and Whatcom County, Washington. Three years passed without a confirmed find, and in December 2024 USDA and the Washington State Department of Agriculture announced the hornet eradicated nationwide (WSDA). WSDA still cautions that a species that arrived once could arrive again.
AgriLife experts have added that our hot, open country is a poor fit for the species. Every U.S. nest located (four, over 2020 and 2021) was inside a hollow alder in Washington.
Stone Oak's big wasps, side by side #
| Insect | Size and look | Where you see it | Sting |
|---|---|---|---|
| Cicada killer | Up to about 1 1/2 in, reddish head and thorax, black-and-yellow abdomen | Sunny lawns, beds, bare soil, summer | Males can't; females rarely |
| Tarantula hawk | Up to 2 in, shiny blue-black, wings orange or dark | On flowers, or dragging a tarantula | Very painful, but rarely used on people |
| Yellowjacket queen | Large, mostly orange | Near ground nests, spring and fall | Yes, can repeat |
| Baldfaced hornet | About 3/4 in, black and white | Paper carton hanging in a tree | Yes, defends nest |
| Pigeon horntail | Hornet colors, no waist | Anywhere; look for the missing waist | Cannot sting |
For the record, the true giant hornet measures 1.5 to 2 inches and carries a wide, bright orange-yellow head that matches or beats the width of its shoulders. On a cicada killer, AgriLife points out, the head is the narrower part, a quick tell from a photo. Pages for the look-alikes: cicada killer, tarantula hawk, yellowjacket and baldfaced hornet.
Where you saw it tells you a lot #
- Hovering over dime-size holes in the lawn: cicada killers. AgriLife says control is rarely warranted for this beneficial insect.
- On flowers along a trail, say at Mud Creek Park or Gold Canyon Park, two of the parks the city's 2026 draft plan lists east of US 281: often a tarantula hawk feeding on nectar.
- Many wasps streaming into one hole in the ground: a yellowjacket colony, which is worth treating if it is near people.
- A gray paper ball in a tree: a baldfaced hornet or a Mexican honey wasp nest.
- A big bee drilling perfectly round holes in wood: a carpenter bee.
Inside the city or in Timberwood Park, report it the same way #
"Stone Oak" mailing addresses cover more than one kind of place. The Census Bureau's 2020 ZIP-to-place file shows 9.9% of the 78258 ZIP's land is in Timberwood Park, an unincorporated community, as is 74.7% of 78260, while 99.6% of 78261 lies outside any town (Census ZIP-place file). The core of Stone Oak is part of San Antonio.
For a suspected giant hornet, none of that matters, because the report does not go to a city or to Bexar County. TAIS's instructions are simple: take a picture without getting close, then submit it with Texas A&M Entomology's online insect identification form. Beekeepers who suspect hornets are raiding a hive can reach TAIS by phone at 979-321-5827 or by email at [email protected]. WSDA only takes Washington reports.
