Termite Control Companies in Houston, TX

Houston is one of the toughest termite cities in the country. On top of the Eastern subterranean termites found across Texas, the metro has an entrenched Formosan subterranean population — an aggressive species whose colonies run much larger and consume wood faster than the natives. The Gulf Coast climate does the rest: long, humid warm seasons, mild winters that never knock colonies back, heavy rains and flat, slow-draining ground that keeps soil moist against foundations. After major storms and flooding, moisture trapped in walls gives Formosan colonies exactly what they need to build above-ground carton nests inside a structure. Species background, statewide swarm timing and licensing rules are on the Texas termite page — what follows is the Houston layer.

Termite risk in Houston

Risk in Houston tracks construction and age more than zip code. The older inside-the-Loop neighborhoods — the Heights, Montrose, Garden Oaks, Third and Fifth Ward — still have plenty of pier-and-beam bungalows with crawl spaces, mature trees and original wood framing, a combination that invites subterranean termites. Those homes warrant annual inspections as a baseline, and crawl-space ventilation and wood-to-soil contact are the first things to fix.

Most of the metro, though, is slab-on-grade: post-war ranch houses and the 1980s–2000s subdivisions of Katy, Sugar Land, Cypress, Spring and Pearland. A slab is not termite-proof — colonies enter through expansion joints, plumbing penetrations and settlement cracks, and the slab edge hides the mud tubes. Garage walls, bathroom plumbing chases, and anywhere mulch, stucco or landscape timbers meet the soil are the classic weak points a termite inspection should cover. Because Formosan termites are established here, an inspector should also check attics and wall voids when a moisture problem is present — Formosan nests do not always need ground contact.

Comparing pressure across the state? Dallas faces steady native subterranean pressure without the Formosan layer, while San Antonio shares the I-35 corridor profile with drywood termites becoming more common toward the border.

Prices

Local Houston pricing is collected in the Prices block below on this page. As a general orientation, national ranges apply: a standalone inspection runs $75–$250 (often waived if you proceed with treatment) and treatment runs $225–$2,500 depending on method and home size — with Formosan work and any fumigation sitting at the high end. For the method-by-method breakdown, see our termite treatment cost guide.

Choosing a termite company in Houston

Termite work in Texas is regulated by the Texas Department of Agriculture’s Structural Pest Control Service (TDA SPCS). Any company treating your home must hold a TDA business license, and the work must be directed by a certified applicator. Before signing, ask each company on the list below:

1. What is your TDA business license number and the certified applicator’s name? (Verify both with TDA.)
2. Which species did you find — Eastern or Formosan — and will you put that in writing? Species changes the treatment plan and the price.
3. Which method are you proposing — liquid soil treatment or bait stations — and why for this house?
4. What does the warranty cover: retreatment only or damage repair, and is it transferable if I sell?

Get two or three written inspections before committing — Houston’s market is large and competitive, so scheduling is easy, and differences in scope are often more informative than differences in price.
