Yellowjacket Control in Boerne, TX
Around Boerne, yellowjackets are usually found the hard way: a mower pass or a weed trimmer sends a stream of small black-and-yellow wasps out of a hole in the lawn, a flower bed or a bank. The right first move is to back off, mark the hole from a distance, keep mowers, kids and dogs away from it, and not pour anything down it. Then call or text (210) 281-1064, or book online, so a technician can look at it.
Why are late summer and fall the touchy months? #
Queens start colonies alone in spring. By August and September the colony is at its peak, and new queens and males appear in October and November. Texas A&M AgriLife notes that the wasps can turn aggressive while foraging, especially in fall, and that yellowjacket nests outnumber bee nests at that time of year. Most nests die after the first hard frost, but AgriLife sources also report that some Texas colonies carry over and keep growing in sheltered sites or mild winters.
Size varies a lot. AgriLife's field guide mentions up to 4,000 workers, while its wasp bulletin describes Texas nests of up to 20,000 workers and 6 feet across (E-239). Either way, a ground nest you mowed over in September is not a do-it-yourself job.
Big lots, long mowing days: the Boerne ground-nest problem #
A Boerne mailing address covers far more than the city. Census files show the 78006 ZIP spans 345.9 square miles, about 95% of it outside any town, and the city fills only 3.3% of it (Census ZCTA file). Many homes with this address sit out in the county, and if yours is one of them, mowing and trimming may cover far more ground than a city yard.
That matters because yellowjackets most often nest underground, in yards and along roadsides, and AgriLife says they also move into old rodent burrows. Mower vibration is a known trigger for an attack. On a big lot, walk the route before the first fall mowing, watch for steady traffic in and out of one spot, and flag it.
Parks, picnics and trash cans #
The city lists 10 parks, and City Park and River Road Park both sit along Cibolo Creek (City of Boerne parks). Yellowjackets scavenge sweet drinks and food scraps, so a few circling a trash can at a picnic is common in fall. At home, the AgriLife fix is simple: keep lids on outdoor cans and empty them often, so foragers do not learn your patio is a food stop.
Yellowjacket, honey bee or "hornet"? #
- Yellowjacket: about 1/2 inch, smooth and shiny, bright black and yellow, no pollen on the legs. The queen is much larger and mostly orange.
- Honey bee: fuzzy, browner, carries pollen, builds wax comb. See honey bee control in Boerne.
- "Hornet": many people call yellowjackets hornets. A gray paper ball in a tree may be a baldfaced hornet, which is a yellowjacket relative.
The yellowjacket guide has more on species and nest structure.
What not to pour, plug or swat #
Do:
- Leave an out-of-the-way nest alone and mark it so nobody mows over it.
- Seal gaps around eaves and siding before spring.
- If you are attacked, cover your head and get inside a building or car.
Don't:
- Pour gasoline down the hole. It is a fire hazard and contaminates soil.
- Soak a ground nest with liquid spray; AgriLife says it tends to sink into the soil.
- Plug a hole in a wall while the colony is alive. Trapped wasps may chew their way indoors.
- Swat, or jump into a pool to escape.
- Count on traps to end a colony.
