Termite Control Cost Guide

Termite treatment costs vary by an order of magnitude depending on species, infestation severity, structure size, and the chemical or mechanical method selected. This guide breaks down the full cost landscape for residential and commercial termite control in the United States — from initial inspection fees through post-treatment warranties — with structured comparisons across treatment types, geographic risk factors, and service contract structures. Understanding the cost drivers helps property owners evaluate bids, verify contract terms, and avoid common pricing traps.

Definition and scope

Termite control cost refers to the total expenditure associated with detecting, eliminating, and preventing termite infestations in a structure. The scope covers direct treatment fees, inspection charges, structural access costs, follow-up monitoring, ongoing warranty or bond coverage, and, where applicable, repair costs for wood damage. A complete cost picture extends beyond the initial treatment invoice.

The U.S. termite damage and control market represents one of the largest pest-related expenditures in real property ownership. The U.S. Department of Housing and Urban Development (HUD) recognizes termite damage as a material defect category in federally related mortgage transactions. The U.S. Environmental Protection Agency (EPA) regulates the termiticide products used in treatment, requiring registered labels under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), which directly influences which treatment options are legally available and at what cost in each state.

Geographic scope matters: the International Residential Code (IRC), maintained by the International Code Council (ICC), establishes termite hazard maps that define mandatory prevention and treatment thresholds in construction. Properties in ICC Termite Infestation Probability (TIP) Zones 1 and 2 — covering the Southeast, Gulf Coast, and portions of California — carry structurally higher treatment frequencies and therefore higher long-term costs than Zone 4 properties in the northern tier.

Core mechanics or structure

Termite treatment pricing is built from four cost components that combine differently across service types.

1. Labor and technician time. Chemical treatment of a typical 1,500 square-foot slab foundation home requires 2–4 hours of trenching, drilling, and injection work. Larger pier-and-beam structures or multi-story buildings scale labor proportionally. Fumigation of the same structure requires 3 separate technician visits across 3 days: tent installation, gas introduction, and tent removal with clearance testing.

2. Chemical or material cost. Termiticide volume is calculated by linear feet of foundation perimeter and, for sub-slab injection, by the number of drill points. The EPA Office of Pesticide Programs maintains the registered label for each termiticide, specifying minimum application rates. Bait station systems involve upfront hardware cost (per-station pricing typically runs $30–$60 per station for installation, with 10–20 stations per average residential lot) plus recurring inspection and bait cartridge replacement.

3. Structure complexity and access. Pier-and-beam foundations, finished crawlspaces, foam insulation boards installed against foundation walls, and multiple concrete add-ons (patios, stoops, attached garages) each add drilling and access time. Wood treatment services for localized drywood termite infestations are priced differently than whole-structure fumigation.

4. Ongoing service and warranty cost. Most treatment contracts include a defined warranty period — commonly 1 year — with optional renewal into a termite bond arrangement. Annual renewal fees typically run $150–$400 for residential properties, depending on treatment type and geographic risk zone.

Causal relationships or drivers

Six primary variables drive termite control pricing in the United States.

Species and infestation type. Subterranean termites, including the highly destructive Formosan termite, require soil barrier or bait system treatment and are priced by linear footage of treatment zone. Drywood termites infesting localized areas may be treated with spot injection at lower cost, but whole-structure infestations require fumigation, which is the most expensive single treatment category.

Structure size and foundation type. EPA-registered liquid termiticide labels specify treatment volume per 10 linear feet and per rod (12 inches depth). A 2,500 square-foot slab home has roughly 200 linear feet of perimeter; a 5,000 square-foot home roughly doubles that and proportionally scales chemical and labor costs.

Infestation severity. Termite infestation severity levels affect treatment scope. An isolated active gallery may cost $300–$900 to treat with targeted liquid application; a whole-structure Formosan infestation can push fumigation and follow-on soil treatment to $3,000–$8,000 for a mid-size home, per contractor estimates validated against National Pest Management Association (NPMA) published cost guidance.

Geographic region and climate. High-TIP-zone states — Florida, Louisiana, Texas, South Carolina, Georgia, Hawaii, and California — face higher treatment frequency requirements, higher chemical consumption per treatment cycle, and greater demand, all of which compress competitive pricing and elevate baseline rates compared to northern states.

Treatment method selected. Liquid termiticide barrier treatments and bait systems have different cost structures at installation and over time. Fumigation carries higher upfront cost but eliminates whole-structure drywood infestations in a single event. Heat treatment and microwave treatment involve specialized equipment rental costs that differ from chemical approaches (see heat treatment termite control).

Licensing and insurance overhead. State-licensed termite control operators carry liability insurance and state registration fees that are embedded in pricing. Unlicensed operators who undercut these costs represent a regulatory risk and a warranty void, not a cost savings.

Classification boundaries

Termite control costs fall into five distinct service categories with non-overlapping pricing structures:

Inspection-only. A termite inspection service — typically a Wood Destroying Organism (WDO) inspection required for real estate transactions — costs $75–$175 in most markets. The inspection itself does not include treatment; it produces a Wood Destroying Organism Report documenting findings.

Spot or localized treatment. Targeted injection, foam application, or boron wood treatment for confined active areas. Typically $300–$900 depending on access and material volume.

Whole-structure liquid barrier or soil treatment. Liquid termiticide applied to foundation perimeter, sub-slab, and soil zones. For average residential structures, market ranges run $500–$2,500. See liquid termiticide treatments and termite soil treatment services for method detail.

Bait station system installation and monitoring. Initial installation $800–$2,500 for a residential lot; annual monitoring contracts add $200–$450 per year. Detailed program mechanics are covered in termite bait station systems and termite monitoring programs.

Whole-structure fumigation (tent fumigation). The highest-cost single intervention, averaging $1,200–$4,000 for residential structures, with commercial or large historic properties reaching significantly higher figures. Structural access, tent sealing, and mandatory Occupational Safety and Health Administration (OSHA) hazard communication requirements under 29 CFR 1910.1200 add compliance cost that licensed operators build into pricing. See termite fumigation tenting services.

Tradeoffs and tensions

The lowest upfront cost option — targeted spot treatment — carries the highest risk of recurrence cost where infestations are broader than visually apparent at the time of treatment. Whole-structure approaches eliminate more colony nodes but impose higher immediate expenditure and, for fumigation, 2–3 days of displacement.

Bait station systems are lower-cost at installation but generate recurring annual costs. A 10-year cost-of-ownership comparison frequently shows bait systems equaling or exceeding the cost of a single liquid barrier treatment plus annual renewals, depending on the local re-treatment frequency.

Termite warranty and protection plans introduce a financing tension: operators price renewal fees to cover expected re-treatment probability in the local market. High-risk Gulf Coast properties generate statistically more warranty callbacks, which is priced into annual renewal rates in those markets.

Pre-construction treatment (see termite pre-construction treatment) is substantially less expensive per square foot than post-construction intervention because soil access is unrestricted before the slab is poured. The cost differential is codified in ICC requirements for TIP Zones 1 and 2, where pre-treatment is mandated for new construction.

Common misconceptions

Misconception: The cheapest bid uses the same product as higher bids.
Termiticide label-specified application rates are minimum rates set by EPA registration. Lower bids sometimes reflect sub-label application volumes, which void the product's efficacy data and may violate FIFRA requirements. Verifying the bid specifies the termiticide product name and application rate per the registered label is a factual comparison step.

Misconception: A termite bond covers repair costs.
Standard termite bonds typically cover re-treatment only. Repair-and-retreat bonds, which cover structural repair costs, are a separate and more expensive contract class. The distinction is defined in the termite bond explained reference page and in the contract documents operators are required to provide under most state pesticide application regulations.

Misconception: Fumigation is always the most thorough option.
Fumigation eliminates aboveground drywood colonies but does not create a soil barrier against subterranean termites. A structure fumigated for drywood termites remains fully exposed to subterranean re-infestation without a separate soil treatment.

Misconception: Termite damage is covered by standard homeowners insurance.
The Insurance Information Institute and HUD both document that standard homeowners insurance policies treat termite damage as a maintenance exclusion, not a covered peril. This is covered in detail at homeowners insurance and termite damage.

Checklist or steps (non-advisory)

The following sequence describes the standard set of documented steps involved in obtaining and evaluating termite control cost estimates. This is a reference description of the process, not advice on any individual situation.

  1. Obtain a licensed inspection. A state-licensed inspector documents active infestations, conducive conditions, and prior damage. The inspection report forms the basis for any treatment scope.

  2. Identify the termite species present. Species identification determines which treatment categories are applicable. Termite species identification resources describe the distinguishing characteristics of the four primary U.S. structural pest species.

  3. Request itemized bids from a minimum of 3 licensed operators. Each bid should specify: termiticide product name and EPA registration number, application volume and rate, treatment zone linear footage, warranty terms, annual renewal fee, and state license number of the operator.

  4. Verify operator licensing. State pesticide regulatory agencies maintain public license lookup databases. Licensing requirements by state are catalogued at termite control service licensing requirements US.

  5. Compare contract terms, not just upfront price. Termite control service contracts vary in re-treatment triggers, warranty transfer provisions, and cancellation terms. Two identical upfront prices can represent materially different 5-year costs.

  6. Evaluate damage repair scope separately. Termite damage assessment and termite damage repair services are distinct from treatment cost. Structural repair estimates should be obtained from licensed contractors with documented wood-destroying organism damage experience.

  7. Confirm re-treatment policy in writing. Re-treatment protocols differ by operator and method. The re-treatment policies termite control reference page documents the range of industry re-treatment trigger standards.
