Solitary Stinging Insects in Bandera, TX: Mud Daubers to Cow Killers
Four stinging insects around Bandera live solitary lives: mud daubers, cicada killers, tarantula hawks and velvet ants. Each female raises her young alone, so there is no colony to come pouring out at you, and all four rarely sting unless someone handles them or steps on them barefoot. Most need no treatment at all; the main jobs are scraping mud nests, wearing shoes and keeping hands off. If you are not sure what you are looking at, or one keeps turning up where children play, call or text Pest Trappers at (210) 281-1064 or book online.
Four insects that work alone #
- Mud dauber. Slender, 3/4 to 1 inch, with a long thread-like waist; black, blue-black or black and yellow. Builds tubes or lumps of dried mud under eaves, in garages and in sheds. See mud daubers in Bandera.
- Cicada killer. Up to about 1 1/2 inches, dark red head and thorax, black abdomen with yellow bands. Digs dime-sized holes with soil piles in sunny lawns in summer. See cicada killers in Bandera.
- Tarantula hawk. Up to 2 inches, iridescent blue-black with orange or black wings. Feeds on flowers and hunts tarantulas. See tarantula hawks in Bandera.
- Velvet ant. A wingless female wasp that looks like a fuzzy ant, often red and black, about 3/4 inch. Runs across bare ground in summer. See velvet ants in Bandera.
None of them build the paper nests that paper wasps, yellowjackets and hornets defend. For those, start at our wasp sorting page.
No colony, no counterattack #
AgriLife's wasp bulletin says solitary wasps rarely sting unless they are mishandled or trapped against the skin, and that their venom usually causes no more than brief pain (E-239). Male cicada killers, male tarantula hawks and male velvet ants cannot sting at all. Female mud daubers do not even defend their nests.
A pain guide, from mild to legendary #
"Rarely stings" does not mean "never hurts." When one of these does sting, the experience varies a lot:
| Insect | What the sources say about the sting |
|---|---|
| Mud dauber | Clemson rates the black and yellow mud dauber a 1 on a 1-to-4 scale, like a fire ant |
| Cicada killer | Sharp pain and local swelling (AgriLife B-6118); females sting mainly when handled or stepped on |
| Velvet ant | "Extremely painful" (B-6118), usually much worse than a bee sting |
| Tarantula hawk | One of three insects rated 4, the top score, on the Schmidt pain index; fades within minutes (TPWD) |
For any sting, watch for trouble breathing or swallowing, dizziness, vomiting or a spreading rash, and get medical help quickly if they appear.
Where they turn up across Bandera's rock, river and open country #
Each of the four follows a different resource, and Bandera has a good supply of all of them.
- Rock for the spider hunters. Texas Parks and Wildlife notes the many limestone outcrops along the Medina River (TPWD), and AgriLife says tarantulas, the tarantula hawk's prey, are met more often in the rockier parts of Central and Southwest Texas.
- Open ground outside town. Most homes with a Bandera address sit on county land in a 226.7-square-mile ZIP code rather than inside the small city. Sunny, bare, well-drained soil suits cicada killers, and sandy open patches are where velvet ants hunt for the nests of ground-nesting bees and wasps.
- Mud after the storms. The National Weather Service recorded 5 to 6 inches of rain in Bandera County and near Medina Lake on June 14 and 15, 2026 (NWS). Mud supply is one of the three things TAIS says a mud dauber weighs in choosing a site, along with shelter and spiders.
What needs doing, and what doesn't #
- Mud daubers: scrape nests off with a putty knife and remove them even if treated. Spraying is for allergy cases or heavy numbers by a busy door.
- Cicada killers: usually leave them. Wear shoes on the patch, and after the season cover bare garden soil with fabric and mulch. Treat only when burrows crowd a play area or someone is allergic.
- Tarantula hawks: leave them. Colorado State recommends no control, and they pollinate milkweed.
- Velvet ants: shoes and education. AgriLife says effective control is limited.
One more check: mud climbing a foundation from the soil may be termite shelter tubes, not dauber nests. That needs an inspection, not a putty knife.
