Velvet Ant (Cow Killer) Control in Kerrville, TX
Most Kerrville sightings of velvet ants happen on a hot summer day: a fuzzy insect about 3/4 inch long in loud red and black, sprinting across a sidewalk, a sandy patch or a bare spot in the lawn, sometimes squeaking when it is cornered. It is not an ant but a wingless female wasp, and her sting is far worse than a bee's. You rarely need to do more than leave her alone, wear shoes and keep small hands off; if you are seeing a lot of them near a play area, or other ground-nesting stingers too, call or text (210) 281-1064 or book online.
Not an ant, and no threat to the cattle #
Velvet ants belong to a wasp family called Mutillidae. Insects in the City explains that the females have no wings and wear a velvety coat, while the males have wings and look more like ordinary wasps (ENT-3004). The red velvet ant, the one people call the cow killer, is black with orange-red markings. Other species are black, brown, orange or white, and most are much smaller.
The nickname is about the sting, not the body count. TPWD's magazine says plainly that they can't really kill cows (TPW Magazine). Their bodies are so hard that crushing one is difficult, which is one more reason not to try it with bare hands.
City lot or county acreage: they turn up in both #
Insects in the City says these wasps live in Texas in summer in both urban and rural settings, and Kerrville offers plenty of each. The city itself is compact: the Census Bureau's 2024 estimate counts 25,141 residents (Census estimates) on about 22 square miles of land. The 78028 ZIP code that carries the Kerrville name is far larger; by the Census relationship file, the city fills just 8.3% of its land area (Census ZCTA file).
Small lot in town or acreage in the county, the advice below is the same.
Why one shows up: following the ground nesters #
A female velvet ant crawls quickly over the ground hunting for the nests of ground-nesting bees and wasps. She lays her eggs in their nests, and her young feed on the host's brood. Insects in the City notes the females search sandy areas, while the winged males fly low over grass looking for females.
That makes a velvet ant a pointer, not a resident. She travels alone and builds nothing on your house. If you see one now and then, she is passing through. If you see them repeatedly in one sunny, sandy patch, there may be ground-nesting bees or wasps there; our solitary stinging pests page for Kerrville and cicada killer page help sort those out.
The sting, and what to do about it #
AgriLife's venomous animals bulletin rates the sting as extremely painful and points out how long the stinger is; Insects in the City says it usually hurts much more than a bee sting. Only females sting. The good news is that people are usually stung once, mostly from walking barefoot where the wasps are or picking one up.
Insects in the City's first-aid notes boil down to three steps:
- Wash and disinfect the spot, treating it like any bee sting.
- Cool it with ice, and take a pain reliever if you need one.
- Head for medical care at once if a rash spreads well beyond the sting or breathing gets hard.
What helps and what doesn't #
Helps:
- Shoes in sandy or bare areas all summer, for adults and children.
- Teaching kids that a fuzzy, brightly colored "ant" is not a toy.
- Leaving a lone wanderer alone; she will move on.
Doesn't help much:
- Spraying the yard. Insects in the City admits there are few good ways to control them, and puts awareness and sturdy footwear at the top of its list.
- Trying to squash one barehanded, given how hard the body is.
