Whole-Structure Fumigation in Los Angeles — Total Pest Elimination.
Fumigation is the most thorough pest elimination method available for widespread drywood termite infestations and pervasive pest problems that cannot be addressed by localized treatments. We manage the entire process from structural access coordination to re-entry clearance.
Licensed · Insured · LA-Based
Signs You Have a Problem
- Multiple areas of the structure showing active drywood termite frass or gallery damage — widespread infestations that have reached multiple roof members, wall framing, or floor joists are typically better addressed by fumigation than by attempting multiple localized treatments
- Repeated localized termite treatment failures — areas that have been spot-treated multiple times and continue showing active termite activity likely have a more extensive infestation than localized treatment can address
- Wood boring beetle infestations (Anobiidae or Bostrichidae) throughout structural lumber — powderpost beetles and other wood borers in widespread structural wood require whole-structure treatment for complete elimination
- Confirmed bed bug infestations that have spread to multiple rooms or to hard-to-access areas such as wall voids, behind built-in furniture, and inside structural framing
- Stored product pest infestations (grain beetles, flour moths, Indian meal moths) that have spread throughout a pantry or storage area and cannot be fully addressed by discarding infested products alone
- Pre-sale pest clearance required by lender or real estate transaction — many Los Angeles residential real estate transactions require a current pest report; identified drywood termite activity may require fumigation clearance before escrow closes
Our Treatment Process
- 1
Pre-Fumigation Inspection and Scope Definition
We conduct a thorough inspection of the structure to confirm the pest species, infestation extent, and whether whole-structure fumigation is the appropriate treatment or whether localized alternatives are viable. We document all affected areas, discuss the fumigation process with you in detail, and provide a firm scope of work and timeline.
- 2
Preparation and Scheduling
Fumigation requires vacating the structure for 24–72 hours depending on structural volume and weather conditions. We provide a detailed preparation checklist — removing or sealing food and medications in certified fumigation bags, removing plants and pets, notifying neighbors and property management if applicable, arranging alternate accommodation. We coordinate a specific fumigation date and timeline with you.
- 3
Structure Tenting
Our licensed fumigation crew drapes the structure in impermeable tarps sealed at ground level to contain the fumigant gas (sulfuryl fluoride). Warning signs are posted as required by California law. Neighboring properties are notified. The fumigant is metered into the tented structure at a precisely calculated concentration based on structural volume, temperature, and target pest. We monitor gas concentration throughout the fumigation period using Vikane gas concentration readers.
- 4
Aeration and Clearance Testing
After the required exposure period, the tent is opened and the structure is aerated — fans are used to accelerate gas dispersal through all structural voids and living spaces. We conduct air quality testing with calibrated equipment to confirm that sulfuryl fluoride concentration has dropped below the California-mandated re-entry threshold (1 ppm) before issuing a clearance for re-entry. We do not issue clearance until testing confirms safe levels.

Post-Fumigation Documentation
We provide a written completion report documenting the fumigant used, application concentration, exposure duration, and clearance test results. This documentation satisfies real estate disclosure requirements and pest inspection certification. We also note any structural repairs needed (gaps in the structure that required special tenting accommodations) and any areas of pest damage observed during preparation.
How to Prepare for Treatment
- Remove or double-bag in certified Nylofume fumigation bags all food items, medications, vitamins, tobacco products, and pet food that will remain in the structure during fumigation — unsealed consumables must be removed or will be contaminated
- Remove all people, pets (including fish and reptiles), houseplants, and potted plants from the structure — sulfuryl fluoride is lethal to all living organisms and there are no safe re-entry protocols for plants or animals during fumigation
- Arrange confirmed alternate accommodation for the full fumigation and aeration period (minimum 24–48 hours, may be longer for large or poorly ventilated structures)
- Notify your homeowners or renters insurance in advance if required by your policy — some policies require notification for structural work of this nature
- Provide access keys or combinations to all interior locked areas — closets, rooms, and storage areas must be accessible and open during fumigation so gas can penetrate all spaces
- Unlock or remove all interior doors to allow gas circulation throughout the structure — deadbolted interior doors or sealed rooms create under-concentration zones where pests survive
After Treatment: What to Expect
- Do not re-enter the structure until we have issued a written clearance — the clearance is based on actual air quality testing, not just elapsed time
- Ventilate the structure fully on re-entry — open all windows and doors for 30 minutes before occupying the space, even after clearance has been issued
- Discard any food items that were not removed or properly bagged before fumigation — do not consume food that was present in the structure without a certified fumigation bag
- Wash dishes, utensils, and cookware before use after fumigation — surface residue from the fumigant is minimal but recommended practice
- Any structural repairs needed after tenting (damaged weatherstripping, torn screens) should be addressed promptly — entry points that required special tenting attention represent ongoing pest entry risks if left unrepaired
- Schedule an annual inspection to monitor for new termite activity — fumigation eliminates all current infestation but does not prevent new swarmers from reinfesting the structure in future swarm seasons
Fumigation Services — Frequently Asked Questions
Standard residential fumigation in Los Angeles requires vacating the structure for a minimum of 24 hours from tent placement, with re-entry permitted only after a certified clearance test confirms gas levels below 1 ppm. In practice, most LA residential fumigations require 48–72 hours from tent-up to clearance, depending on structural volume, weather conditions (temperature affects gas circulation), and the scheduled clearance testing time. We provide a specific timeline estimate when we schedule your fumigation.
Fumigation is the most reliable treatment for widespread drywood termite infestations but is not required for all situations. Localized infestations that are well-mapped and accessible can be treated with spot injection of termiticide foam or dust, electro-gun treatment, or microwave treatment without vacating the structure. We make this determination during the inspection based on the number and location of active sites. We recommend fumigation only when localized options are genuinely insufficient.
Yes. Sulfuryl fluoride fumigation kills all living organisms within the tented structure including insects at all life stages (adults, larvae, pupae, and eggs), rodents, and other pests. Fumigation is used for drywood termites, bed bugs, wood boring beetles, cockroaches, and stored product pests. However, fumigation does not provide residual protection — it does not prevent new pests from entering after the tent is removed. Exclusion work and preventive treatment are still necessary after fumigation.
Properly conducted fumigation with licensed operators and appropriate tenting is safe for neighboring properties. Sulfuryl fluoride is heavier than air and does not drift significantly under proper tenting conditions. California regulations require warning signs, neighbor notification, and licensed monitoring of the fumigation. You may notice the tarped structure but there is no exposure risk to neighboring households from a properly managed fumigation.
