Termite Treatment Cost in California (2026)
No source we found publishes a measured California termite treatment price, so the prices here are national estimates, named and dated. What California does set is the paperwork behind every quote: an inspection report split into Section I and Section II items, a separate licence branch for tenting, and a signed fumigation notice before any gas is used.
What termite treatment costs: national figures
These are national compiled estimates, shown exactly as each publisher states them. None of them is specific to California, and we do not adjust them for California: no source we could find publishes a state price index for termite work, so any adjustment would be our guess. A written quote after an inspection of your home is the only California price.

Section I and Section II: how a California inspection report splits the work
A California Wood Destroying Pests and Organisms Inspection Report is a separated report. Section I lists items with visible evidence of active infestation or infection, or of conditions that resulted from one. Section II lists conditions likely to lead to infestation or infection where no visible evidence was found. Reports are completed as the Structural Pest Control Board prescribes, and copies are filed with the Board.
That split is the useful way to read a quote: compare what each company prices for the Section I items, then decide on the Section II items separately. Before you buy or sell, the Board's Wood Destroying Organism search shows whether a specific property has been inspected within the last two years. Nationally, HomeGuide puts a real estate termite inspection at $100 to $325; see termite inspection cost.

Tenting a California house: who may do it and what you sign
UC IPM calls the western drywood termite California's second most important termite pest after subterranean termites. Drywood colonies live inside the wood, so they are treated with a whole-structure method (fumigation or heat) or locally. UC IPM recommends a whole-structure treatment when the extent of the infestation is uncertain, because one can never be sure every colony has been found with a local treatment. Fumigation empties the house for several days; heat for hours.
| SPCB licence branch | What it covers |
|---|---|
| Branch 1, Fumigation | Household and wood-destroying pests controlled by fumigation with poisonous or lethal gases: tenting. |
| Branch 2, General Pest | Household pests, excluding fumigation. Not termite work. |
| Branch 3, Wood Destroying Organisms | Termites and other wood-destroying pests controlled by insecticides or structural repairs and corrections, excluding fumigation. The Board ties WDO inspection filings to Branch 3 companies. |
So the company that inspects and the company that tents can be different, and each needs the right branch. Before a fumigation, the prime contractor must hold an Occupant Fumigation Notice and Pesticide Disclosure form signed by the occupant or owner, naming the pest, the fumigant and its active ingredient, and stating that a lethal gas will be used on the dates shown and that it is unsafe to return until a re-entry notice is posted. The Board's consumer guide says a fumigation can take from six hours to one week.
For the price, our termite fumigation cost page applies HomeGuide's national per-square-foot rate to your home size and lists the Vikane label's prep and re-entry rules; the alternatives are on the no-tent termite treatment and heat treatment pages.

How we priced this
- No California price is published by any source we could fetch, so the figures are national compiled estimates from HomeAdvisor, HomeGuide and Bob Vila, shown as each states them, from the same records as the termite treatment cost page. We do not adjust them for California: no source publishes a California price index for termite work.
- Rules and species: California Code of Regulations title 16, the Structural Pest Control Board and UC IPM, read 23 October 2026.
- Operator count: the SPCB licensee file, counted at build. See the methodology.
California termite species
UC IPM names subterranean termites as California's most important termite pest and the western drywood termite (Incisitermes minor) as the second. Drywood termites are commonly found along the Pacific coastal region, extending into the Central Valley and the deserts of Southern California.
- Formosan: we found no current UC IPM distribution statement to cite, so we do not map them.
- Drywood: common along the Pacific coast, into the Central Valley and the Southern California deserts (UC IPM).
- Main metro areas: Los Angeles, San Diego, San Francisco, San Jose, Sacramento

California regulation, inspection form and lenders
Pest control in California is licensed by the California Structural Pest Control Board (SPCB). When a home is sold, the wood-destroying insect inspection is reported on the Wood Destroying Pests and Organisms Inspection Report, completed as the Board prescribes. The report is separated into Section I, items with visible evidence of active infestation or infection or of damage from it, and Section II, conditions likely to lead to infestation where no visible evidence was found.
Lenders. VA lists California among the states where wood-destroying insect information is required for the whole state before it issues a Notice of Value. For an FHA loan on an existing home, HUD Handbook 4000.1 makes the lender confirm the property is free of wood-destroying insects and order a pest inspection when the appraiser sees evidence of infestation or a prior treatment. A new-construction FHA loan needs the builder's Subterranean Termite Protection Builder's Guarantee (form HUD-NPMA-99-A), because no California county is on HUD's Termite Treatment Exception Areas list. A conventional lender sets its own rule, so ask yours.
Check the company and its branch on the Structural Pest Control Board's licence search before you sign a contract or pay a deposit: Branch 3 for termite inspection and treatment, Branch 1 for tenting.
We republish the Structural Pest Control Board licensee file by metro area, with each company's registration number and whether its licence covers Branch 3, the termite specialty: California licensed operator register (3,747 businesses)

Frequently asked questions
How much does termite treatment cost in California?
No source publishes a California price. National compiled estimates: HomeAdvisor puts one treatment project at $263 to $1,033; HomeGuide puts whole-home liquid soil treatment at $500 to $2,000 or more, bait stations at $1,000 to $2,500 and tenting an average-sized home at $2,000 to $8,000. A written quote against your inspection report's Section I items is the California price. Checked 23 October 2026.
How much does it cost to tent a house for termites in California?
No California price is published. HomeGuide puts tent fumigation at $1 to $4 per sq ft nationally, and $2,000 to $8,000 for an average-sized home. In California the tenting itself must be done by a company licensed in Branch 1 (fumigation), and the prime contractor must hold an Occupant Fumigation Notice signed by the occupant or owner before the gas is used. Checked 23 October 2026.
What is the difference between Section 1 and Section 2 on a California termite report?
California's report rule (16 CCR 1990) splits the report. Section I contains items with visible evidence of active infestation or infection, or of conditions that resulted from it. Section II contains conditions deemed likely to lead to infestation or infection where no visible evidence was found. Compare quotes on the Section I work first, and treat Section II as a separate decision.
Can I find out whether a California house has had a termite inspection?
Yes. The Structural Pest Control Board's Wood Destroying Organism search shows whether a specific property has been inspected within the last two years. Inspection reports are filed with the Board.
Which California licence does a termite company need?
The Structural Pest Control Board licenses three branches. Branch 3 (Wood Destroying Organisms) covers termites and other wood-destroying pests controlled by insecticides or structural repairs, excluding fumigation; Branch 1 (Fumigation) covers control by poisonous or lethal gases, which is tenting; Branch 2 is general household pests. Check the branch on the Board's licence search before you sign.
