How Much Does Fumigation Cost in California? (2026 Pricing Guide)

The Primary Cost Driver: Linear Feet of Structure

Fumigation is priced by the cubic footage of the structure being treated (the space the fumigant must fill), but most contractors quote using linear footage of the building perimeter as a proxy. The standard unit in California is "per linear foot" of structure, measured at the roofline. For a typical single-story home:

• 1,200 sq ft home (140 linear feet): $1,200–$2,000
• 1,800 sq ft home (175 linear feet): $1,600–$2,800
• 2,500 sq ft home (210 linear feet): $2,200–$3,800
• 3,500+ sq ft home or multi-story: $3,500–$6,000+

What's Included in a Fumigation Quote

A complete fumigation quote should include:

• Pre-fumigation inspection to confirm active drywood termite infestation (or bed bug infestation for Vikane use)
• Tenting — installation of the fumigation tent over the structure
• Fumigant (Vikane/sulfuryl fluoride is the industry standard) — typically priced per 1,000 cubic feet
• Clearance testing using a fumiscope/infrared detector before re-entry is authorized
• Post-fumigation inspection and re-entry authorization
• Nylofume bag supply for food items that must be bagged or removed
• Secondary lock installation (required by CA law — 'FUMIGATION' locks on all access points)

What Isn't Included (and Often Surprises Homeowners)

• Alternative housing for 24–72 hours: You must vacate the structure and all pets for the fumigation period. Budget $150–$400 per night for a hotel, depending on number of people and pets.
• Food preparation: All food, medications, and items with natural membranes (fresh produce, wine corks) must be either bagged in Nylofume bags or removed. Figure 2–4 hours of preparation time.
• Structural repairs: Fumigation kills active termites but doesn't repair existing damage. If the inspection reveals significant structural damage, repair costs ($500–$10,000+) are separate from fumigation.
• Re-entry permits: California requires a licensed fumigation company to issue a signed re-entry authorization before occupants return. This is included in reputable quotes but confirm it.

Monterey and Santa Cruz County Pricing Context

Central California fumigation costs run somewhat higher than the state average due to labor costs in coastal communities. Monterey County and Santa Cruz County fumigation quotes typically run 10–20% higher than the Central Valley or Inland Empire. The Salinas area, being slightly inland and with lower local labor costs, tends to be priced at or slightly below the Monterey city/Carmel/Santa Cruz market.

Fumigation vs. Spot Treatment: When Each Is Appropriate

Fumigation is the right choice when multiple infested areas are present throughout the structure, prior spot treatments have failed, or you want the highest confidence before a real estate transaction. Spot treatment (orange oil, borates, direct injection) is appropriate when the infestation is isolated. Spot treatment costs $300–$1,500 and doesn't require vacating the structure, but for a home with activity in the attic, multiple window frames, and a wall void, fumigation is often the better economic choice — spot-treating all those areas combined often approaches fumigation cost.

What Drives Price Variation Between Contractors

Legitimate factors that cause one quote to be higher or lower:

• Tent ownership vs. rental — contractors who own their tenting equipment have lower variable costs
• Fumigant concentration — the amount of Vikane used is calculated based on temperature, wood density, and infestation severity. A lower-cost quote may reflect lower fumigant concentration
• Clearance testing — some contractors charge separately for this, others include it
• Company insurance and licensing costs — fully licensed, insured operators have higher overhead
• Crew size — fumigation is physically demanding work; some contractors use minimum-size crews
