How Much Does Termite Treatment Cost in Texas? — A Homeowner's Price Guide

Published: 2026-09-19 · Updated: 2026-09-19 · 5 min read · By Huntsville Termite Solutions

Termite treatment costs in Texas range from about $300 for a localized liquid treatment on a small structure to $2,500 or more for a full-perimeter Formosan treatment on a larger home with active infestation. The range is wide because termite treatment is not a single product — it's a combination of labor, materials, property size, species, and infestation severity that all vary by job.

This guide covers the realistic price ranges for each treatment type, what drives the differences, and how to evaluate a termite treatment quote so you're not guessing.

What Does a Termite Inspection Cost?

A standard residential termite inspection in the Huntsville, TX and Walker County area typically runs $75 to $150. Some companies offer free inspections — that fee is typically rolled into the treatment cost if you proceed, or waived as a lead generation practice. A standalone inspection from an independent specialist that produces a written report costs in that range.

A WDI (Wood Destroying Insect) inspection report required for real estate closing is a specific type of inspection with specific documentation requirements. These typically cost $100 to $175 because the report must be completed on a state-approved form by a licensed inspector and is a legal document that becomes part of the real estate transaction.

Termite Treatment Cost by Type

Liquid Barrier Treatment (Most Common)

Non-repellent liquid termiticide — products like Termidor SC (fipronil) or Altriset (chlorantraniliprole) — is applied by trenching around the structure's perimeter, drilling through slab or concrete patio sections, and treating the soil at the foundation. This creates a chemical barrier in the soil that termites cannot detect and carry back to the colony.

• Small home under 1,500 sq ft: $400–$800
• Average home (1,500–2,500 sq ft): $700–$1,400
• Large home over 2,500 sq ft: $1,200–$2,200
• Formosan infestation (same home sizes): Add 25–40% for additional product and re-treatment requirements

Liquid treatment pricing is primarily driven by linear footage of the structure's perimeter (how much trench needs to be dug and treated) rather than square footage of the home itself.

Termite Bait Station Systems

In-ground bait stations — Sentricon, Trelona, or comparable systems — are installed around the perimeter at 10 to 15-foot intervals. They contain an active bait that worker termites carry back to the colony, eliminating the colony over 3 to 6 months. After elimination, the stations remain as monitoring points.

• Initial installation: $800–$1,800 depending on perimeter size and number of stations
• Annual monitoring and bait replenishment: $250–$500 per year
• Why ongoing cost exists: Stations need to be checked, refilled, and replaced periodically. The annual service is what keeps the system effective.

Bait stations cost more upfront for smaller infestations compared to liquid treatment, but they are the appropriate solution for waterfront properties (where liquid barriers have regulatory setbacks), properties with sensitive landscaping, or clients who want ongoing colony monitoring rather than a one-time treatment.

Drywood Termite Treatment (Spot or Whole-Structure)

Drywood termites — which infest above-ground wood without soil contact — require different treatment. Options include spot treatment (injecting termiticide directly into galleries through drilled holes) or whole-structure fumigation (tenting).

• Spot treatment per location: $200–$500
• Whole-structure fumigation: $1,500–$4,000+ depending on home size

Fumigation is rarely the first recommendation. Spot treatment is effective for limited, localized drywood infestations. Fumigation is appropriate for widespread, inaccessible infestations — particularly in attic framing — where locating every gallery is not practical.

What Affects Termite Treatment Cost Most

• Perimeter size: Liquid barrier is priced by linear foot of foundation. A home with a complex footprint (multiple additions, attached garage, wrap-around porch) costs more to treat than a simple rectangle of the same square footage.
• Species: Formosan termite treatment requires more product volume and is more labor-intensive than native subterranean treatment. Formosan inspections sometimes reveal carton nests in wall voids that require targeted elimination separate from perimeter treatment.
• Foundation type: Slab foundations require drilling through concrete to access the soil beneath. Pier-and-beam homes allow direct soil access through the crawl space but may require more coverage area.
• Infestation severity and duration: Active, widespread infestation with damaged wood typically requires more aggressive treatment than a recently discovered, limited colony.
• Retreatment warranty: Most reputable companies include a 1-year retreatment warranty. Some offer multi-year or renewable warranties for additional annual cost ($150–$300/year). Ask specifically what the warranty covers.

What Termite Repair Costs

Treatment eliminates the colony. It does not repair the damage already done. Repair costs are separate and can be significant:

• Minor damage (one or two sill plates, small joist section): $300–$800
• Moderate structural damage: $1,500–$4,000
• Severe structural damage to floor framing, load-bearing walls, or roof members: $5,000–$15,000+

Standard homeowners insurance policies in Texas do not cover termite damage. It's classified as a maintenance and prevention issue, not a sudden loss. This makes early detection — before significant structural damage accumulates — the most cost-effective outcome for homeowners.

How to Evaluate a Termite Treatment Quote

1. Ask what species was identified and confirm it's documented in writing.
2. Ask whether the price includes the full perimeter or only the affected section — partial treatment is cheaper but leaves untreated gaps.
3. Ask what the warranty covers: does retreatment cost extra, or is it included?
4. Ask whether the inspection was performed by the same person quoting the treatment — independent inspection vs. sales-inspection conflict.
5. Compare quotes for the same treatment type, not across treatment types (bait vs. liquid quotes are not apples-to-apples).
