Yellowjacket Control in Schertz, TX
In Schertz, yellowjackets usually give themselves away as a steady stream of small black-and-yellow wasps flying in and out of one hole, either in the lawn, along a flower bed edge or in a gap in the siding. Once you see that traffic, keep people, pets and the mower well clear of it and plan to have the nest treated; an established colony is a job AgriLife says should go to professionals. Call or text (210) 281-1064, or book online, and the office will set a time.
First, is it really a yellowjacket? #
People in Schertz call all kinds of things "hornets," and yellowjackets get mixed up with honey bees all the time. A quick check:
- Yellowjacket: about 1/2 inch, shiny and smooth, bold black and yellow bands, clear wings, no pollen on the legs. Nests are hidden: underground, in a wall, or in a closed paper ball.
- Honey bee: fuzzy, browner, carries pollen, builds wax comb. See bee control in Schertz.
- Paper wasp: longer and slimmer with dangling legs, and an open comb you can see into. See paper wasp control in Schertz.
A very large, mostly orange wasp in spring may be a yellowjacket queen. The yellowjacket guide has photos and the full life cycle.
Why a busy suburb suits them #
The San Antonio River Authority's Cibolo Creek plan describes the Selma, Schertz, Universal City and Cibolo area as the most heavily populated part of the whole watershed (SARA). That kind of setting does not bother southern yellowjackets at all. AgriLife's field guide calls the species abundant in urban areas and lists yards and roadsides among its usual haunts.
Neighborhood life also feeds them. Foragers work open trash cans hard, and AgriLife notes they can turn aggressive while foraging, especially in the fall. Closing lids and emptying outdoor cans daily takes away a lot of the draw.
Tall grass, mowing day and the city's 8-inch rule #
Most yellowjacket nests are underground, often in an old rodent burrow, and the entrance is easy to miss in thick turf. That is why so many stings happen behind a mower: the vibration sets off the colony before anyone sees the hole.
The City of Schertz lists weeds or grass over 8 inches among its common code violations, and residents can report a problem property through 311 (Code Enforcement). If the lot next door has gone shaggy, a nest along your shared fence line is more likely to go unnoticed until someone trips over it. Before you mow any long grass, walk the area slowly and watch for a hole with wasps going in and out.
The calendar here #
AgriLife's timeline runs like this: a queen starts the colony in spring, numbers peak by August and September, and new queens and males come out in October and November. Most nests die after the first hard frost, but Texas sources note that in sheltered spots or mild winters a colony may carry over and keep growing. Late summer and fall are when Schertz yards see the most trouble.
What not to pour, plug or set out #
- Gasoline down the hole: a fire hazard that also contaminates the soil.
- A bucket of water or spray liquid: it soaks into the ground and often misses the comb.
- Plugging a hole in the wall: with the colony still alive, the wasps may chew their way into the house instead.
- Traps: they catch foragers but do not take out a colony.
- Swatting or jumping in the pool: if wasps pour out, cover your head and get inside a building or car.
Mark the hole with a flag or a lawn chair so nobody steps on it, and keep anyone with a venom allergy or heart condition away.
How Pest Trappers treats yellowjacket nests in Schertz #
