Fumigation in San Mateo, CA

Full-Structure Vikane Fumigation · Drywood Termites · Bed Bugs

When a drywood termite infestation has spread beyond what localized treatments can effectively address — multiple infested structural members, evidence throughout the framing, or inaccessible areas — fumigation is the single most thorough treatment available. 101 Exterminators performs full-structure fumigation using Vikane (sulfuryl fluoride), the industry's gold standard fumigant, providing complete penetration to every void, joint, beam, and piece of framing in your structure.. Serving San Mateo and surrounding San Mateo County.

Why San Mateo Homes Need Fumigation Services

Drywood termite pressure in coastal Monterey and Santa Cruz counties is significant — the combination of older wood-frame construction and Mediterranean climate creates ideal conditions for colony establishment throughout structural framing. When colonies are present in multiple locations, localized treatment addresses individual galleries but leaves others untreated. Full fumigation eliminates all colonies simultaneously, including those in inaccessible cavities.

Drywood termites are active in older housing stock throughout central San Mateo. Subterranean termites are present in bayshore and low-lying neighborhoods with higher water tables. The city's active real estate market — driven by proximity to San Francisco and Peninsula tech employment — means WDO inspection demand is consistent year-round.

San Mateo Climate

San Mateo has a mild Peninsula Mediterranean climate — warmer and less foggy than Daly City to the north, with summer temperatures typically reaching the mid-70s°F. Annual rainfall averages 19–21 inches. The combination of moderate warmth and adequate moisture creates conditions where both drywood and subterranean termites are active for extended seasons.

Housing Stock

San Mateo's older neighborhoods — Hayward Park, Baywood, North Central — have Craftsman bungalows and early-20th-century construction with original wood framing at various stages of termite exposure. Post-WWII tract housing dominates the mid-city areas. The Hillsdale corridor and newer Bay Meadows development represent modern construction. The range from 1910 to 2020 construction means termite risk and species composition vary significantly by neighborhood.

Why Local Expertise Matters

San Mateo's mix of historic Craftsman neighborhoods and post-war development requires experience with both drywood termite treatment in older framing and subterranean termite management in bayshore soils. We hold SPCB License #9119 and provide WDO reports that meet Peninsula real estate transaction standards.

Our Fumigation Process in San Mateo

Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in San Mateo.

01

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.

02

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.

03

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.

04

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.

Fumigation You Can Count On in San Mateo

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.

Fumigation FAQs for San Mateo

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.
