Termite Fumigation Los Angeles — Complete Drywood Termite Elimination
OCP Pest Control's licensed Vikane fumigation eliminates 100% of drywood termites throughout your entire LA home in one treatment.
Licensed · Insured · LA-Based
How It Works
Whole-structure fumigation using Vikane (sulfuryl fluoride) is the California Department of Pesticide Regulation (CDPR)-licensed treatment recognized as the gold standard for eliminating drywood termites throughout an entire structure. It is the only treatment method that simultaneously reaches every piece of wood, furniture item, and void within the structure regardless of accessibility, making it the preferred approach when drywood termite activity is detected in multiple locations throughout an LA home. OCP Pest Control holds active CDPR structural fumigation licenses and employs certified fumigants required by California law.
Sulfuryl fluoride (Vikane) is a colorless, odorless, non-flammable gas that penetrates all materials — wood, concrete, plaster, and furniture — distributing evenly throughout the tented structure. At the required concentration and exposure time (calculated as CT value: concentration × time), the gas interferes with cellular respiration in insects, killing all life stages including eggs, nymphs, and adults. After treatment, the structure is aerated to below the 1 ppm CDPR clearance level before any re-entry is permitted.
What Pests It Targets
Treatment Process
- 1
Pre-Fumigation Inspection and Preparation
OCP conducts a full inspection documenting all termite damage locations and confirms the structure's suitability for fumigation. A detailed preparation checklist is provided to the homeowner covering food bagging, medication removal, and plant care.
- 2
Structure Tenting
The entire structure is draped with multi-layer fumigation tarps (Fumigans or equivalent) and sealed at the foundation using sand snakes and weighted materials. A secondary fumiscope seal is placed around door openings. Warning agents (warning agents with tear-gas component) are posted at all entrances.
- 3
Gas Introduction and Monitoring
Sulfuryl fluoride is introduced into the sealed structure in calculated doses based on cubic footage, temperature, and wood density. Concentration levels are monitored at multiple points throughout the structure using fumiscope monitoring equipment over the 24–72 hour treatment period.
- 4
CT Value Verification
OCP's licensed fumigant confirms that the required concentration-time (CT) value has been achieved at all monitoring points — a California legal requirement. No early aeration is permitted until CT requirements are met throughout the entire structure.
- 5
Aeration and Clearance Testing
Tarps are removed and the structure is aerated for a minimum of 6 hours with all windows and doors open. Before re-entry is permitted, all areas of the structure are tested with a calibrated gas detection instrument to confirm levels below 1 ppm — the CDPR re-entry clearance standard.
Pros & Cons
Advantages
- Only treatment that reaches all wood in the structure simultaneously, including inaccessible areas
- Eliminates all life stages of drywood termites — including eggs — throughout the entire structure
- Required for whole-structure WDPO clearance in California real estate transactions
- Effective against multiple pest species simultaneously: termites, bed bugs, and stored-product pests
- Established, well-regulated industry standard with over 50 years of use in California
Limitations
- Requires 24–72 hours of evacuation including pets — occupants must arrange alternative accommodation
- No residual protection — new termites can enter the structure after fumigation
- All food, medications, and plants must be removed or double-bagged in Nylofume bags
- Not effective against subterranean termites, which require soil-barrier treatment
Pricing Factors
- Total cubic footage of the structure — the primary cost driver for LA homes
- Roof complexity and tenting difficulty for LA multi-story or complex roofline structures
- Whether WDPO report clearance documentation is required for real estate purposes
- Distance and logistics for multi-structure properties or LA hillside properties with limited access
- Re-inspection and clearance certification included in OCP fumigation packages
How to Prepare
- Remove or double-bag all food, beverages, medications, and vitamins in certified Nylofume bags provided by OCP
- Remove all plants, pets, fish tanks, and living organisms from the structure
- Arrange 2–3 nights of alternative accommodation for all occupants and pets
- Unlock all interior doors, attic access hatches, and crawl space entry points
- Trim all vegetation to at least 12 inches from the structure to allow proper tarp sealing
- Coordinate with neighbors regarding shared fences or overhanging structures if present
Whole-Structure Fumigation — Frequently Asked Questions
Most LA residential fumigations require 24–72 hours of evacuation, typically 2 nights and 3 days. The exact timeline depends on structure size, temperature, and achieved CT values. OCP provides a confirmed re-entry date and time after clearance testing — you cannot return until OCP certifies the structure is below 1 ppm Vikane.
Yes — this is one of the key advantages of Vikane fumigation over localized spot treatments. Sulfuryl fluoride penetrates wood to the cellular level and kills all life stages including eggs at required CT values. Spot treatments with orange oil or foam cannot guarantee egg kill in wood not directly contacted.
Yes. OCP performs calibrated gas detection throughout the home before authorizing re-entry. Vikane does not leave surface residue — it dissipates completely during aeration. There are no surfaces to wipe down and no residual chemical on furniture, dishes, or children's toys after clearance is confirmed.
No — fumigation eliminates all existing termites but leaves no residual barrier. New drywood termites can enter the structure during the next swarming season. OCP recommends annual termite inspections and can apply borate preventive wood treatments to exposed wood during attic inspections to provide longer-term protection.
