How It Works
Our Fumigation Process in San Leandro
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in San Leandro.
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 San Leandro
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 San Leandro
How long do we need to be out of the house for fumigation?
Plan for 3 full days and 2 nights out of the structure for a typical residential fumigation. Day 1: tent and introduce gas. Day 2: maintain concentration and begin aeration. Day 3: complete aeration, clearance testing, and re-entry authorization. We provide exact timelines at booking.
What do we need to remove from the house before fumigation?
Food, medications, vitamins, and pet food must be removed or placed in Nylofume bags (we supply these). Plants, cut flowers, and all living organisms including pets must be out. We provide a complete preparation checklist that is reviewed with you at the pre-fumigation inspection.
Does fumigation affect my furniture, electronics, or belongings?
Vikane is a gas that penetrates and then dissipates — it does not leave residue on surfaces or damage electronics, fabrics, or materials. Normal household items do not need special preparation beyond the food and medication bagging requirements.
Will fumigation kill other pests besides termites?
Yes — fumigation kills all insects present in the structure including bed bugs, cockroaches, stored product insects, and other pests. However, fumigation does not leave residual protection, so re-infestation from the exterior can occur afterward.
Is fumigation guaranteed?
We provide a written warranty on the treated infestation for drywood termites. If the same colony reappears post-fumigation (which is rare given proper dosage), we investigate and retreat at no charge.
