Velvet Ant (Cow Killer) Control in Bulverde, TX
The bright red, fuzzy "ant" sprinting across a sunny patch of a Bulverde yard in summer is not an ant at all. It is a female velvet ant, a wingless wasp nicknamed the cow killer, and she can deliver a sting AgriLife describes as extremely painful. She travels alone, builds no nest and moves on, so the right first move is simple: let her pass, and make sure everyone has shoes on.

Not an ant: what you're actually looking at #
Velvet ants belong to the wasp family Mutillidae. AgriLife's B-6118 describes them as wingless wasps that look like fuzzy ants, and that matches what most people see:
- Females: no wings, a dense velvety coat, and a fast, searching run along the ground. The red velvet ant is about 3/4 inch, black with orange-red markings.
- Males: winged and more wasp-like. B-6118 says they fly low over grass looking for females. Males cannot sting.
- Other species: Insects in the City says most velvet ants are black or brown, many with red, yellow or orange markings, and run from about 1/2 to 1 inch.
- Odd traits: both sexes can squeak when cornered, and the body is so hard it is difficult to crush.
Our velvet ant guide covers the family in more detail.
Barefoot season around Bulverde #
Insects in the City says velvet ants turn up in Texas in summer, in both urban and rural settings, and that most stings happen to people walking barefoot or picking one up. That makes summer habits more important than any treatment.
Summer pulls everyone outside. The city's 13-acre Bulverde Community Park on Bulverde Lane has walking trails and a splash pad, and a splash pad is exactly where kids go shoeless. We have no reports of velvet ants at the park itself; the point is that any sunny lawn or path edge, at a park or at home, is worth a glance before little feet run across it.
New construction is another reason to look. Bulverde is still building, with 10.5% of its homes put up in 2020 or later according to Census housing data. Insects in the City notes that females search sandy areas, so a newer yard with patches of bare ground where turf hasn't filled in yet is worth checking each summer.
Why a spray won't solve it #
Velvet ants are parasites. B-6118 says females invade the nests of ground-nesting bees and other insects to feed their own young, and Insects in the City adds that the next generation spends the winter inside those host nests. They don't build nests of their own on a house or in a yard.
That is why Insects in the City says effective control measures are limited. Spraying a lawn rarely touches a lone wanderer, and the long-term approach is about the hosts and about people:
- Wear shoes in sandy or bare areas in summer.
- Teach children not to touch or pick up fuzzy "ants."
- Don't try to crush one with bare hands; the shell is very hard.
- Leave single wanderers alone. They keep moving.
If someone gets stung #
Only females sting. B-6118 notes the stinger is very long, and Insects in the City says the sting is usually much more painful than a bee sting. Because she travels alone, a person is unlikely to get more than one.
Clean and disinfect the sting the way you would a bee sting, then use an ice pack and an over-the-counter pain reliever as needed. Get medical care immediately if the person develops a rash beyond the sting site or has trouble breathing.
When Pest Trappers can help #
Most homes never need a visit for velvet ants. It can make sense if you're seeing many of them around a play area, if ground-nesting bees or wasps (their hosts) are busy close to the house, or if you want to be sure what's stinging people. A technician inspects the yard and foundation, identifies the insects involved and explains what is worth doing, including when the honest answer is shoes and patience. Any product is used according to its label, and pricing follows the inspection.
