Structure Fumigation
Fumigation in Oakland, CA
101 Exterminators performs whole-structure fumigation in Oakland with Vikane (sulfuryl fluoride) when a drywood termite infestation has spread past what spot work can reach, a common finding in the pre-1925 bungalows and flats from West Oakland to the Dimond. We are California licensed, SPCB Lic. #9119, and have worked structural pest jobs. The inspection decides it.
Home maintenance
How do you keep drywood termites from returning to an Oakland house after fumigation?
Seal the wood the tent just cleared and watch it each fall. Fumigation kills the drywood colonies inside the structure on the day it runs and leaves nothing to stop the next swarm. With 38.8% of Oakland’s homes built in 1939 or earlier, much of the exposed wood is original trim on bungalows and Victorians, and that trim needs regular paint.

Repaint trim before the next swarm
Drywood swarmers enter through cracks and bare wood. In the months after the tent comes down, scrape and repaint weathered fascia, window casings and porch trim, and caulk open joints before late summer.
Check decorative gable vents from inside
On a Craftsman or Victorian, look at the gable and attic vents from inside the attic, where the screen sits. Replace torn or missing mesh so winged termites can’t fly straight into the framing.
Patch old holes and write down where
Vacuum the old pellet piles and fill the small kick-out holes with wood filler. Note each spot, so a new pile in the same room next fall reads as fresh activity.
Look at detached garages and studios
A fumigation covers the structure under the tent. A detached garage, shed or backyard studio left outside it can hold its own colony, so check its trim and window sills for pellets too.
Watch for pellets in September
September is Oakland’s warmest month, averaging a 74.6°F high at the Oakland Museum station, and drywood swarms run from late summer into fall. Check sills, the attic hatch and furniture near windows for pellets and shed wings.
When to do it
Paint and screen repairs through the spring and summer after the tent; a pellet check each September and October.

When to Ask About Fumigation in Oakland
We manage the entire fumigation process: pre-fumigation inspection and documentation, structure tenting with certified fumigation tarps, introduction of Vikane fumigant to specified concentration, aeration protocol, post-fumigation clearance testing, and coordination with a certified fumigation clearance company before you return. We also provide bagging requirements and preparation guidance for food, medications, and plants.

Previous localized treatments that have not resolved the infestation
Inspector-identified infestation in inaccessible areas (wall cavities, sealed areas)

How It Works
What to Expect from Fumigation in Oakland
If you already have a pest inspection report, have it ready when you call. The findings and access to the structure help determine whether fumigation is appropriate.
Pre-Fumigation Inspection
We document all entry points, confirm the infestation scope, measure the structure for gas calculation, and review the preparation checklist with you at least 3 days before the fumigation date.
Structure Tenting
Our crew tents the entire structure with specialized fumigation tarps, sealed at the foundation to prevent gas escape. Neighbors are notified as required, and warning signs are posted.
Gas Introduction & Monitoring
Vikane is introduced to calculated concentration and held for the required exposure time. Readings are monitored throughout the process to confirm effective dosage.
Aeration & Clearance
The structure is thoroughly aerated until Vikane levels are below the safe entry threshold. A certified third-party inspector confirms clearance levels before we authorize re-entry.
Why 101 Exterminators
Why Choose 101 Exterminators for Fumigation in Oakland
Complete Structure Coverage
Gas fumigant penetrates every void, cavity, and piece of wood in the structure — including areas impossible to reach with liquid or foam treatments.
Vikane — Industry Gold Standard
Vikane (sulfuryl fluoride) is the most widely used and thoroughly studied structural fumigant. It leaves no residual after aeration — the structure is safe to re-enter after clearance.
Third-Party Clearance Testing
Re-entry is only authorized after independent clearance testing confirms gas levels are below threshold. No guesswork on when your home is safe.
Real Estate Compliant
Fumigation clears all Section 1 termite conditions for real estate transactions. We issue the required Completion Notice accepted by lenders and escrow companies.
Common Questions
Fumigation FAQs for Oakland
Can you tent a house in Oakland when the neighbor's wall is only a few feet away?
Usually yes. Narrow side yards are normal across the Oakland flats, and Alameda County tarp crews work them regularly. What we check on the site visit is whether the tarp can be run and sealed along both setbacks, whether a fence, deck or overhanging tree has to be worked around, and where equipment stages on the street. Buildings that physically share a wall are the real limit, and those get a different plan.
How long do I need to be out of my Oakland home for a termite fumigation?
The household stays out for the full sequence, which runs tenting and gas introduction, the required exposure period, then aeration and a clearance check before re-entry is authorized. That means at least one night away, and the exact window is set when the job is scheduled. You get the bagging list then too, covering food, medication and anything else staying behind. Pets and houseplants leave with you.
My inspector found termites in three rooms of my Temescal flat. Is spot treatment still an option?
Three separated findings usually points toward fumigation, but access decides it rather than the count. Local treatment works when every gallery system can be reached and treated directly: an exposed rafter, a window header, a porch post. When evidence appears in framing behind finished plaster or inside wall cavities we cannot open, spot work leaves colonies alive and the frass returns. We tell you plainly which one your building is.
