Pest Control San Antonio: $100 to $600 + Local Facts (2026)

We found no San Antonio price from a publisher we use. Every row is a national figure and is labeled that way; the company that answers quotes its own first-visit or inspection fee before anything is booked.

Do this now, before you call a San Antonio exterminator

1. If someone has trouble breathing, swelling of the face or throat, or dizziness after stings or bites, call 911. Everything else below can wait a few minutes.
2. Photograph what you saw and where: the insect, the droppings, the mud tube, the bite pattern. Keep a dead sample in a sealed bag if you can. A company identifies the pest before it prices anything, and NC State's advice for bed bugs applies everywhere: ask the technician to show you a live specimen from your home before you accept a treatment.
3. Do not spray store-bought products over the area first. Repellent sprays scatter roaches into new rooms (UC IPM) and hide the evidence a company would use to find the source.
4. If the winged insects showed up in January or February, do not assume it is too early for termites. Texas A&M says native subterranean termite swarms begin in South Texas in January and February, months before the rest of the country.
5. If you rent, put the problem in writing to the address where you pay rent. Texas Property Code 92.052 requires a landlord to make a diligent effort to repair a condition that materially affects the health or safety of an ordinary tenant once a current tenant gives notice, and 92.056 presumes 7 days is a reasonable time.

Is it urgent? What counts as a pest emergency in San Antonio

Three situations are worth a prompt call, and none of them is a verdict on your house: a wasp or hornet nest at a door, a deck or a play area; rodents inside a home with young children, since mice and rats gnaw wiring and contaminate food; and winged termites or shed wings inside the house, which Texas A&M and NC State both describe as the usual sign of an active colony in or under the structure. San Antonio's swarm calendar runs early: Texas A&M puts the first native swarms in South Texas in January and February, so winged insects on a sill in winter are a termite question, not a fluke.

Everything else, a few ants at the sink, an occasional roach, a spider in the garage, can wait for a normal booking. HomeGuide's one-time visit range of $100 to $600 covers the ordinary cases; the high end belongs to bed bugs and termites, where the first visit is usually an inspection with a written quote.

Termites in San Antonio: early swarms and a Formosan county

Two Texas A&M facts set San Antonio apart. First, native subterranean termites (Reticulitermes) begin swarming in South Texas in January and February, compared with April and May in the Panhandle, so the season here opens in winter. Second, Bexar County is on Texas A&M's list of counties where Formosan subterranean termites have been found; Formosan swarmers fly at night from early May through June and come to lights, while natives fly by day.

A company would check the slab edge and any pier-and-beam crawl space for mud tubes, probe door frames and baseboards that sound dull, and look for shed wings on sills and in cobwebs. Texas A&M's prevention list is the same list an inspector reads off: keep soil several inches below the top of the slab, prune shrubs off the walls, and fix the leaks that keep wood damp. HomeGuide prices treatment at $225 to $2,500 nationally, bait stations at $7 to $12 per linear foot and soil treatment at $3 to $20 per linear foot; see termite treatment cost.

Fire ants and roaches around San Antonio homes

Red imported fire ants cost Texas an estimated $1.2 billion a year, Texas A&M's fire ant project says. HomeGuide's national ant range is $200 to $300, up to $1,200 for severe infestations, and cockroach work is $100 to $600. The Census puts San Antonio's median home at 1985, so many houses have 40-year-old weatherstripping and plumbing penetrations, the entry points a company would check on a first visit.

Mosquitoes: what Metro Health does and does not do

San Antonio Metro Health controls mosquitoes on public property inside the city limits, with surveillance from March through October and fogging for adult mosquitoes announced through posted abatement notices, typically around 3 am. Its West Nile counts show why it matters: 32 positive mosquito pools in 2024, 13 in 2025 and 9 through August 11, 2026. Metro Health does not treat private property for insects, rodents or bats; it can inspect your yard and make recommendations with your permission. Call 3-1-1 or 210-207-6000. Private yard treatment is $350 to $500 nationally (This Old House, March 2026).

Check a San Antonio pest control license

Every pest control business and applicator in Texas is licensed by the Texas Department of Agriculture's Structural Pest Control Service: businesses keep insurance on file and applicators complete continuing education each year. TDA posts current business licenses on its Structural Pest Control Business Publications page and takes complaints through the SPCS complaint process. Ask for the TDA business license number and check it before the visit.
