2026 Termite Treatment Pricing — Southern California

What Determines Termite Treatment Cost
Four factors drive the final price of any termite treatment. Understanding them helps you evaluate quotes intelligently.
Termite Species
Drywood vs subterranean require completely different treatments. Getting the wrong treatment (e.g. fumigating for subterranean) wastes money entirely. Correct identification at inspection is step one.
Home Size
Fumigation priced by cubic footage. Termidor priced by linear feet of foundation. Larger homes cost more — but not always proportionally.
Infestation Extent
Early-stage localized activity may need only spot treatment ($200–$600). Whole-house infestations in inaccessible walls require fumigation.
Treatment Type
Chemical vs non-chemical, whole-structure vs localized. An honest inspector recommends the minimum effective treatment, not the most expensive one.
Cost Breakdown by Treatment Type
Every treatment type has a different pricing structure. Here's exactly what you're paying for — and when each treatment makes sense.
Tent Fumigation
$1,500 – $3,500Average SoCal home. Priced by cubic footage. Includes tent installation, Vikane gas, 2-night monitoring, air clearance testing, and written clearance report. Best for widespread drywood termite infestation.
Estimate your fumigation cost → →Heat Treatment
$2,000 – $4,000Chemical-free whole-structure treatment. Same-day return to home — no hotel stay required. Kills all life stages throughout the structure without pesticides.
Learn about heat treatment →Orange Oil (No-Tent)
$300 – $900Per-gallery injection for localized drywood termites. Best for early-stage, accessible infestations. Does not cover whole-house activity — unsuitable for widespread infestation.
Learn about orange oil →Termidor Soil Barrier
$800 – $1,800Priced by linear feet of foundation. Eliminates subterranean termite colonies with 10+ year protection. The gold standard for subterranean control in Southern California.
Learn about Termidor →Spot Treatment
$200 – $600Lowest cost option — appropriate only for confirmed, localized, accessible infestations. Correct identification of extent is critical before choosing spot treatment.
Schedule an inspection →Borate Treatment
$400 – $900Long-term wood protection for accessible framing. Does not degrade — best applied to new framing before drywall installation. Often combined with another primary treatment.
Ask about borate treatment →Don't Forget These Additional Costs
Fumigation requires leaving the home for 2–3 nights. Budget for these costs when comparing quotes — they can add $300–$700 to the total.
Hotel Stay
$150 – $300
2 nights in OC/LA area during fumigation. Required for all occupants.
Pet Boarding
$50 – $100/night per pet
All animals must vacate — mammals, birds, reptiles. Fish tanks require special handling.
Food Preparation
$100 – $300
Nylofume bags provided by us for unsealed food. Budget for food replacement depending on pantry size.
Termite Damage Repairs
$300 – $8,000+
If termites have damaged structural wood, repairs are separate. Minor: $300–$800. Major structural: $2,000–$8,000. We provide repair estimates alongside treatment quotes.
Why We Can't Quote Over the Phone — And Why That Protects You
Pricing requires physically measuring the home. Fumigation requires cubic footage. Termidor requires linear feet of foundation. Any company quoting a final price without seeing the home is either overquoting to protect their margins or underquoting to win the job.
Our free inspection gives you an accurate written quote with no obligation. We measure the home, identify the termite species, assess the extent of activity, and recommend the minimum effective treatment — all documented in writing before you make any decision.
Termite Costs for Home Buyers and Sellers
WDO (Wood Destroying Organism) inspections are free with Ultimate Termite. In Southern California, real estate custom dictates that sellers typically pay for the inspection and any Section 1 clearance work. Section 2 items (conducive conditions) are negotiable between parties.
Section 1 — Active Infestation
Active termite activity or damage caused by it. Must be cleared before most transactions close. In SoCal, seller typically pays.
Estimated cost: $300 – $3,500+ depending on treatment required.
Loan Requirements
- VA loans — always require a clear termite report before closing
- FHA/conventional — required only if appraiser notes visible damage or infestation
- Cash purchases — not required but strongly recommended
Termite Cost FAQs
Does homeowners insurance cover termite treatment?
No — termite damage is considered preventable maintenance and is excluded from virtually all standard California homeowner policies. All treatment and repair costs are out of pocket.
How do I get the most accurate quote?
A free in-home inspection — takes 45–90 minutes, and we provide a written quote the same day. No obligation.
Is the cheapest treatment the right one?
Not always. Orange oil at $400 for a whole-house drywood infestation will fail — you'll end up paying for fumigation anyway. The right treatment depends on species and extent, not price.
Are there financing options for termite treatment?
Yes — we offer payment plans. Ask your inspector for details when they provide the written quote.
How long does termite treatment last?
Fumigation has no residual protection — annual inspections are recommended after fumigation. Termidor lasts 10+ years in the soil. Orange oil has no residual; follow-up inspections at 30/90/365 days are standard.
Can I negotiate the price?
We provide fair written quotes based on actual measurements. We don't inflate to negotiate down — the price you're quoted is based on what the job actually requires.
