European Hornet in Texas? What the Records Show and What You Saw
None of the sources we rely on document the European hornet in Texas. AgriLife counts just one "hornet" on record for the state, the baldfaced hornet, and the closest records west of the Mississippi come from the Ozarks and eastern Oklahoma. If a big brown-and-yellow wasp buzzed your San Antonio yard, it was most likely a cicada killer, a yellowjacket queen, a red paper wasp, a baldfaced hornet or a pigeon horntail.
If big wasps are nesting near your house, call or text (210) 281-1064 or book online and we'll identify them.
Does the European hornet live in Texas? #
Here is what the record shows, source by source:
- AgriLife: the E-239 bulletin lists one "hornet" for Texas, the baldfaced hornet. TAIS says the same thing.
- NC State Extension: the species reached North America around 1840 and has since pushed west to Louisiana and the Dakotas.
- Penn State Extension: Arkansas logged its first report in 1999.
- A 2025 peer-reviewed survey by D.E. Bowles in Entomologica Americana (abstract record): beyond the Mississippi, the bulk of the records cluster in the Ozark region of Arkansas and Missouri and in eastern Oklahoma, plus single specimens from Arizona, California, Kansas, Louisiana and Wisconsin. Texas is not on the list.
So the honest answer is no documented Texas population. That's why we don't advertise European hornet removal here.
Could Texas heat be keeping it out? #
Possibly. Bowles points out that the species' upper lethal temperature is 44 °C and suggests heat may hold it back across the South and Southwest. That is a hypothesis in the paper, not a settled finding, but it fits the gap on the map.
What a real European hornet looks like #
For comparison, here is the genuine article as described by northern extension services:
- Size: Penn State says workers reach 1 inch (25 mm) and queens 1.3 inches (35 mm). NC State gives about 1 1/2 inches. The two sources disagree.
- Head: red and yellow.
- Thorax: red and brown.
- Abdomen: brown toward the front and mostly yellow toward the back. NC State sums it up as brown with broad yellow markings instead of black and yellow.
- Habits: it's active after dark and heads for porch lights and bright windows.
- Nest: usually inside a hollow tree; barns, attics and wall voids now and then.
The five insects most often mistaken for it #
- Cicada killer. AgriLife's B-6118 describes a wasp up to 1 1/2 inches long with a dark red head and thorax, a black abdomen marked with yellow, and russet wings. It digs its nest burrow in soil. Males can't sting at all, and females seldom turn aggressive.
- Southern yellowjacket queen. AgriLife's field guide calls her very large and mostly orange, a striking contrast with the 1/2-inch workers.
- Red paper wasp. Reddish-brown all over, measuring 3/4 to 1 inch, and it builds an open comb nest. See our red wasp and paper wasp guides.
- Baldfaced hornet. About 3/4 inch, black with white markings, building a gray paper nest in trees.
- Pigeon horntail. Big and colored like a hornet, but lacking any visible waist, and it has no sting.
Quick sorting questions #
Why so many wasps get called hornets #
Part of the confusion is the word itself. AgriLife notes that yellowjackets are often called "hornets," and the one Texas insect with hornet in its name, the baldfaced hornet, is a yellowjacket relative. Add the giant hornet detections in Washington state and British Columbia, and AgriLife's 2020 article titled "It's big, but it's not a 'murder hornet'," and any large wasp now gets a second look.
That second look is a good habit. Just match it with a careful identification, because the insect you saw decides what, if anything, needs to happen next.
Why big wasps bump into windows at night #
Night flying and attraction to lit windows are classic European hornet traits where the species lives. Because Texas has no documented population, a nighttime visitor here still needs a real identification. A clear photo, taken from a sensible distance, is the quickest way to settle it.
What a European hornet sting is like #
Where the species does live, Penn State rates the sting about equal to a honey bee's in pain. The stinger is smooth, so one hornet can sting more than once. Unless the person has an allergy or took many stings, the effects usually fade in one to a few hours.
First aid is the same as for any wasp: soap and water first, then ice, and leave it unscratched. CDC/NIOSH says anaphylaxis needs medical care immediately.
What to do after a big-wasp sighting #
Do:
- Snap a clear photo and hold it up against the look-alikes above.
- Note where it's coming from: the ground, a tree, a wall, a light fixture.
- Keep children and pets away from any nest you find.
Don't:
- Block the outdoor opening of a nest that's inside a wall. Penn State warns trapped hornets may chew through to the inside, and AgriLife says the same about yellowjackets.
- Try to treat a nest yourself if you have a venom allergy or a heart condition. AgriLife's E-239 advises against it.
When to make the call #
Call a professional for an enclosed paper nest close to the house or any nest inside a wall. AgriLife's E-239 notes that between the hazards and how hard some nests are to reach, wasp control usually falls to professionals.
How Pest Trappers handles "hornet" calls #
When you call about a hornet, the technician's first task is finding out what you really have, since a yellowjacket colony, a cicada killer burrow and a paper wasp nest each call for a different approach. If the insect doesn't need treatment, we'll say so.
When a nest does need attention, you'll hear the options for that species, and any product used follows its label. Pest Trappers LLC (TPCL #0887549) prices each job after the inspection, so call for pricing. Our town notes for San Antonio, Schertz and Bandera cover the same look-alikes.
