Stink Bug Control in San Antonio
Serving San Antonio Since 1948, With No Contracts & No Sales Pitch
Stink bugs are an overwintering pest, and when fall temperatures drop in San Antonio, they push into structures through surprisingly small gaps, settling into wall voids and attics for the winter. Witten Pest Control has been treating homes and commercial properties across Bexar and Wilson Counties since 1948. Our Texas Department of Agriculture-licensed technicians address both the active population and the entry routes that allow re-entry, helping reduce the chances that the problem repeats next season.
We don’t require long-term contracts, and every job starts with a free estimate. No credit card, no obligation.

Signs You Have a Stink Bug Problem
Catching an infestation early makes treatment more straightforward. Watch for these indicators on your property:
Common signs to look for:
- Wall clusters in fall: Large groups of shield-shaped bugs congregating on south- or west-facing exterior walls signal bugs preparing to move indoors.
- Indoor sightings near windows: Bugs appearing around window frames, wall voids, or warm interior areas indicate the infestation has already entered the structure.
- Unexplained odor: A persistent foul smell with no obvious source can point to a population overwintering inside wall voids or attic spaces.
- Garden activity: Properties with vegetable gardens, fruit trees, or heavy ornamental plantings face higher pressure because these serve as warm-weather food sources directly adjacent to the structure.
Why DIY Methods Fall Short
Vacuuming visible stink bugs removes what you can see but leaves the population overwintering inside wall voids untouched. Over-the-counter sprays compound the problem: they’re low-potency and can trigger the odor-release response in the bugs you’re trying to remove.
Without a perimeter barrier treatment, stink bugs that sheltered inside all winter can emerge again in spring, and the cycle can repeat. Female stink bugs also deposit eggs on plants and structures during warm months, so untreated populations can rebuild season after season. Our technicians hold Texas Department of Agriculture pest control licenses and are trained on current materials and methods. When you call us, you’ll get a straightforward assessment and a solution. We don’t employ salespeople.
How Witten Pest Control Treats for Stink Bugs
Every treatment starts with a thorough site inspection. Our technicians identify congregation areas, overwintering sites, vegetation attractants, and the specific entry routes bugs are using on your property.
Treatment focuses on exterior barrier application along the foundation perimeter, around windows and doors, and under siding, helping intercept stink bugs before they can enter the structure. We also identify gaps around utility penetrations, siding joints, and door frames so those vulnerabilities can be addressed directly. Our professional-grade products follow all label guidelines and are designed with the pets in your household in mind. Witten Pest Control actively supports the Texas Great Pyrenees Rescue and the San Antonio Humane Society, and that commitment to animal welfare extends to how we treat every property.
For properties that need reliable seasonal protection, we offer quarterly pest control services that help keep stink bug pressure managed year-round.

Identifying Stink Bugs in San Antonio
The species you’re most likely to encounter indoors is the brown marmorated stink bug. It has a distinctive shield-shaped body, mottled grayish-brown coloring, and black-and-white banded antennae. Adults range from roughly half to three-quarters of an inch in length. They can fly, though they fold their wings flat against their bodies when at rest, giving them a flat, tile-like appearance.
Stink bugs don’t bite, don’t transmit disease, and don’t cause structural damage. The problem is the foul odor they release when disturbed or crushed, which lingers in enclosed spaces, and the nuisance of a large indoor population. Some individuals experience mild allergic reactions to the odor or to residue left on surfaces, though this isn’t a common health risk. If you’re unsure whether you’re dealing with stink bugs or a similar shield-shaped insect, the mottled brown pattern and the characteristic smell when handled are the clearest distinguishing features.
Stink Bug Seasonal Behavior in the San Antonio Area
From spring through late fall, stink bugs feed outdoors on fruits, vegetables, ornamental plants, and garden crops. As temperatures drop, they begin seeking warm overwintering sites and push into structures through any available gap. Once inside, they move into wall voids, attics, and crawlspaces and enter a dormant state, surviving on stored fat reserves for several months without feeding or reproducing.
When spring warmth returns, that overwintered population begins moving back outside. Large numbers appearing near windows and interior lights in spring are a strong signal that bugs successfully overwintered in the structure. Exterior lights also attract stink bugs at night, concentrating them near entry points during peak fall migration. Properties with vegetable gardens, fruit trees, or dense ornamental plantings are at higher risk because those plants serve as warm-weather food and breeding habitat right alongside the structure.
