Termite treatment in California typically costs $300-$4,000, with many whole-home treatments near $1,800-$2,500. The final price depends on termite species, home size, treatment method, access, and local labor rates; fumigation and extensive subterranean barriers can cost more.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Localized treatment | $300 | $650 | $1,200 | Limited, accessible infestation |
| Liquid soil treatment | $1,200 | $2,200 | $4,000 | Subterranean termites, typical house |
| Whole-structure fumigation | $1,200 | $2,500 | $6,000 | Home size and preparation affect quote |
| Annual monitoring | $200 | $300 | $500 | Renewal or inspection plan |
Typical California termite treatment prices by method
For a standard 1,500- to 2,000-square-foot home with normal access, a localized spot treatment often runs $300-$1,200. A liquid soil barrier for subterranean termites commonly totals $1,200-$4,000, while whole-structure fumigation for drywood termites is often $1,200-$6,000. Many California homeowners budget about $2,000-$3,000 for a substantial whole-home treatment.
Fumigation is sometimes quoted at roughly $1-$3 per square foot of treated structure, though minimum charges and preparation can make small homes cost more per square foot. Spot treatments are priced by affected area and repair access, not simply by house size. Assumptions: standard residential construction, ordinary access, and no major structural repairs.
What soil barriers, fumigation, and labor add to the quote
Quotes can combine chemical materials, technician labor, equipment, and preparation or disposal charges. Ask whether the written estimate covers drilling, trenching, sealing, cleanup, and post-treatment inspection; those tasks may be separate.
| Quote component | Typical charge | What changes it | Common pricing unit |
|---|---|---|---|
| Liquid termiticide | $300-$900 | Product volume and treatment perimeter | $4-$12 per linear ft |
| Application labor | $400-$1,200 | Access, drilling, and crew time | $75-$150 per hour |
| Fumigation equipment and tenting | $700-$2,000 | Structure size and setup difficulty | $1-$3 per sq ft |
| Wood or soil access work | $150-$800 | Concrete, decking, or stored items | Per task or area |
| Inspection and monitoring | $100-$500 | One visit versus annual plan | Per visit or year |
Labor is often a major part of barrier treatment pricing. A two-person crew may spend 3-8 hours on an accessible home; difficult foundations, attached patios, or extensive drilling can extend the workday.
How home size, termite species, and access change price
Home size matters most when a contractor treats the full perimeter or tents the structure. A 1,000-square-foot home may fall near the low end of fumigation pricing, while a 2,500-square-foot home can add hundreds or several thousand dollars depending on roofline, attached structures, and tenting complexity.
Termite type changes the treatment plan. Drywood termites may require localized wood treatment or fumigation; subterranean termites often call for a continuous soil barrier. For a 150-linear-foot perimeter, a $4-$12-per-foot application rate implies $600-$1,800 for that line item before access work and other charges. Concrete slabs, additions, and blocked foundation edges can raise labor costs even when the house is modest in size.
Los Angeles, Bay Area, and inland California price differences
Labor, travel, and local demand can shift comparable quotes. As a planning estimate, dense Bay Area and Los Angeles markets may run about 10%-25% above a lower-cost inland market; remote or high-cost coastal locations can also carry travel or scheduling charges. These are rough comparisons, not fixed regional tariffs.
A $2,000 treatment in a lower-cost market might therefore quote around $2,200-$2,500 in a higher-cost metro before unusual access or repair work. Compare bids for the same treatment scope and warranty rather than comparing totals alone. Confirm whether the contractor measured the full perimeter and included attached garages, decks, or additions.
How long California termite work takes and what labor covers
A spot treatment may take 1-3 hours, while liquid perimeter work commonly takes 4-8 hours for a two-person crew. Fumigation setup and tenting may take most of a day, followed by required aeration and clearance procedures before reentry; the home is generally unavailable for several days.
Labor rates commonly equate to $75-$150 per technician-hour, but contractors usually quote a project price rather than billing each hour. Request a scope showing crew work, access tasks, and any return visit. Emergency scheduling, difficult crawlspaces, or extensive furniture preparation may add charges.
When fumigation costs more than localized wood treatment
Localized treatment can cost less when an inspection confirms a limited drywood termite colony and the affected wood is reachable. Multiple colonies, inaccessible framing, or widespread evidence can make whole-structure fumigation more practical; fumigation treats the structure but does not prevent a new infestation.
Subterranean activity usually requires attention to soil entry points, so a spot spray may not replace a complete barrier. Wood replacement or structural repair is generally a separate expense, often quoted after the damaged area is opened. Ask the inspector to distinguish active infestation from old damage before approving a larger treatment.
Extra charges for prep, tenting, and post-treatment monitoring
Fumigation preparation can involve bagging food and medicine, securing plants, and arranging lodging; some contractors include basic instructions but not labor for moving belongings. Structural fumigation commonly requires residents and pets to leave the home, and lodging or meals can add $150-$600 or more depending on duration and location.
Removing stored items or clearing crawlspace access may cost $100-$500 when the crew performs the work. Annual inspection or monitoring plans commonly add $200-$500 per year. Check the quote for disposal, reinspection, warranty duration, and what triggers a paid retreatment.
Ways to lower a termite quote without skipping needed work
Get at least three written estimates based on the same inspection findings, treatment area, product or method, and warranty terms. Ask whether the quote separates treatment from wood repair, access work, and monitoring so optional expenses are visible.
Clear stored items and provide safe access to the foundation before the crew arrives, if the contractor confirms that preparation is appropriate. Avoid paying for fumigation when a qualified inspection supports a limited treatment, but do not substitute surface spraying for a required soil barrier. The safest savings usually come from matching the treatment to confirmed activity and removing avoidable labor.
