Yellowjacket Control in Kerrville, TX
In Kerrville, yellowjackets usually give themselves away as a steady line of small black-and-yellow wasps flying in and out of one hole in the lawn, a gap in siding or a pile of stored lumber. Sometimes the first sign is a burst of angry wasps around the mower. Either way, stop working near that spot, mark it so nobody walks over it, and have the nest treated rather than poking at it. Call or text (210) 281-1064, or book online.
Is it really a yellowjacket? #
- Size and look: roughly half an inch, slick and hairless, banded black and yellow, with clear wings and nothing fuzzy about them.
- The nest: a paper ball closed except for an entrance hole, most often underground, sometimes in a wall void or attic.
- The queen: much larger and mostly orange, so a big orange wasp in spring may simply be a queen hunting for a nest site.
- What people call them: many folks say "hornet," and they are often mistaken for honey bees. Honey bees are hairy and carry pollen; see bee control in Kerrville if you are not sure.
The yellowjacket guide covers the species found in Texas in more detail.
Mowing season on Kerrville house lots #
Most homes in Kerrville have their own yard. Census survey data for 2020 to 2024 counts 63.2% of the city's housing as single-family detached houses (Census ACS), and that means a lot of lawns, flower beds and edges being cut every week or two.
AgriLife sources place yellowjacket nests in yards, flower beds, embankments and roadsides, sometimes inside abandoned rodent burrows (E-239). The trouble is vibration: a mower or string trimmer passing over the entrance can set the whole colony off. Before you mow a patch you haven't touched in a while, stand back and watch it for a minute. Traffic in and out of one hole is the warning.
Flood cleanup piles: check before you move them #
The National Weather Service reports flash flooding across south-central Texas from July 13 to 17, 2026 (NWS). If cleanup at your place left furniture, lumber or brush stacked outside, keep in mind that AgriLife lists abandoned furniture, sheds and porches among the places yellowjackets will build, and a pile that sits untouched through summer is a quiet place for a colony to grow.
Before you haul off a pile that has been sitting for weeks:
- Watch it for a few minutes in the warm part of the day for wasps going in and out of one spot.
- If you see a steady stream, leave it and have the nest treated first.
- Keep children and pets away from the pile until then.
Why late summer and fall are the touchy months #
A lone queen founds each nest in spring. AgriLife's publications have colonies reaching full size around August and September and turning out new queens and drones in October and November, and warn that foragers get testier as fall goes on, so cover trash and outdoor food then. A hard frost ends most nests, but the AgriLife field guide notes that some Texas colonies carry on for several years and keep growing.
What to do, and what never to do #
Do:
- Keep trash cans closed and emptied often in late summer and fall.
- Seal gaps around eaves and walls once nests are gone.
- Under attack, shield your head and get inside a house or vehicle.
Don't:
- Use gasoline. Beyond the fire risk, it poisons the ground.
- Flood the hole with liquid spray; it tends to soak into the ground and miss the comb.
- Seal a wall opening with live wasps behind it; they can end up forcing a way into the rooms.
- Count on traps, swat at the wasps, or jump into a pool or the river to escape.
