Structure Fumigation
Fumigation in Livermore, CA
101 Exterminators performs full-structure fumigation in Livermore using Vikane (sulfuryl fluoride), licensed in California under SPCB Lic. #9119 Alameda County. Tenting is the answer when drywood termites turn up in several separated parts of a house — a common finding here, where an August-to-October swarm season has been seeding colonies into the same 1960s and 70s framing for decades.
Home maintenance
How do you keep drywood termites from returning to a Livermore home after fumigation?
Seal the outside wood and check it each swarm season. Fumigation kills the drywood colonies inside the tented structure and leaves nothing behind to stop the next flight. Livermore’s July and August highs average 87 to 89°F, the swarm season runs August into October, and the sun that drives those flights also cracks the paint swarmers use to get in.
Repaint sun-cracked trim
Heat past 95°F splits paint on fascia, window trim and patio-cover beams. Scrape and repaint the south and west faces in the spring after the tent, and caulk the joints where trim meets stucco.
Check patio covers and carports
A patio cover, pergola or carport that stood outside the tent may still hold a colony. Look along beams and rafters for small six-sided pellets on the concrete below.
Replace damaged vent screens
Look at attic, gable and eave vents for torn or loose screens and replace them with intact fine mesh, so swarmers can’t fly straight into the attic framing.
Patch old holes and write them down
Vacuum the old pellet piles and fill kick-out holes with wood filler. Note each spot, so a fresh pile in the same place next fall reads as new activity.
Keep outbuildings on the same schedule
On South Livermore Valley and rural parcels, barns, sheds and equipment buildings have their own wood exposed to the same swarms. Paint, screen and check them along with the house.
When to do it
Paint and screen work in spring, before summer heat; a pellet check of eaves and patio covers between August and October.

Warning Signs
When to Ask About Fumigation in Livermore
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.
Multiple locations of frass (termite pellets) throughout the structure — not just one area
Evidence of drywood termites in structural framing, not just surface wood
Previous localized treatments that have not resolved the infestation
Inspector-identified infestation in inaccessible areas (wall cavities, sealed areas)
WDO report showing extensive Section 1 conditions throughout the structure

How It Works
What to Expect from Fumigation in Livermore
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 Livermore
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 Livermore
Is tenting the only way to treat drywood termites in a Livermore house?
No — it depends on how many separate colonies are in the structure and whether we can reach them. Localized activity in accessible wood, like an eave, a patio-cover beam or a window header, is usually a candidate for drill-and-treat, orange oil or borates. Fumigation becomes the right call when galleries show up in several separated areas or inside framing behind stucco that cannot be opened. We show you the inspection photographs behind that recommendation before either option is scheduled.
What has to happen in a Livermore backyard before the tent goes up?
The ground around the whole structure has to be clear enough for the tarps to reach it and seal. That usually means cutting plantings back off the walls, moving potted plants off the property, and removing anything attached to the house that would break the seal — arbors, trellises, shade sails. On Livermore's newer tract lots the side yards are narrow and the fence runs close to the structure, so a fence panel sometimes has to come off. We walk the property with you ahead of the date.
Can a house in the South Livermore Valley wine country be fumigated with vineyards next door?
Yes. Fumigation is a sealed-structure treatment — the fumigant is a gas confined under the tarps, not a surface application to the yard, and it is aerated out under a documented clearance protocol before anyone re-enters. On vineyard-edge and rural parcels we plan the staging differently, since long driveways, outbuildings and irrigation infrastructure change access. Barns, detached garages and wine-storage buildings are inspected as separate structures and tented separately if they need it.
