Structure Fumigation
Fumigation in Fremont, CA
Fumigation in Fremont is what we recommend once drywood termite galleries have spread past what drilling and injection can reach — several framing members, evidence in more than one part of the house, or activity behind finished surfaces. 101 Exterminators tents the structure and introduces Vikane (sulfuryl fluoride), which penetrates every void and joint in the frame. We handle prep, aeration, and clearance. SPCB Lic. #9119.

Signs You Need Fumigation Service in Fremont
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.

How It Works
Our Fumigation Process in Fremont
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in Fremont.
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
Fumigation You Can Count On in Fremont
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 Fremont
Can a townhome near Warm Springs BART be tented for termites?
Only with the neighbors involved. A tent has to seal a complete structure, so an attached unit sharing a party wall means the entire building under that roofline is fumigated together — every household preparing at once, usually with HOA coordination. When that is not workable, we look at drill-and-inject treatment of the accessible members and tell you plainly what it reaches and what it does not.
What time of year is easiest for fumigating a house in Fremont?
The dry stretch from May through September is the simplest window, since Fremont takes about fifteen inches of rain and nearly all of it falls between October and April. Wind matters more than heat here. The breeze off the Bay builds through the afternoon on the flats, so tarping crews work early in the day. Fumigation still happens in winter; it just gets scheduled around storms.
What has to leave the house for a Fremont fumigation?
People, pets, and houseplants leave; furniture, clothing, and electronics stay. Anything meant to be eaten, drunk, or taken as medication gets sealed in the nylon fumigation bags we supply, including opened pantry items and pet food. Unopened cans and bottles with the factory seal intact are fine as they are. Outside the house matters too on a Fremont lot: shrubs and vines have to be cut back off the walls so the tarp can reach the ground, and on the narrow side yards common in the Glenmoor and Parkmont tracts that often means clearing a fence-line hedge before the tarp date. We walk the checklist with you in person first.
