Fumigation in Daly City, 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 Daly City and surrounding San Mateo County.

Why Daly City 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.

Subterranean termites are the dominant structural pest concern — the soil moisture maintained by persistent coastal fog supports large foraging colonies. Crawl space sill plates and floor joists in 1950s homes are the most common damage location. Drywood termites are present in older structures and in the warmer eastern neighborhoods near the 280 corridor.

Daly City Climate

Daly City is one of the foggiest cities in California — marine fog is present most summer mornings and persists through the day in many neighborhoods. Annual rainfall of 20–24 inches, combined with persistent fog humidity, maintains soil moisture year-round. These conditions are highly favorable for subterranean termite foraging and wood decay organisms.

Housing Stock

The Westlake and Serramonte tract developments (1940s–1960s) make up the bulk of Daly City's housing stock. These wood-frame homes were built quickly with standard-grade lumber and have been exposed to coastal moisture for decades. Sill plates, floor joists, and crawl space framing are the primary areas of termite concern. Some older areas near the SF border have pre-1940 construction with greater drywood termite exposure history.

Why Local Expertise Matters

Fog-belt termite work is different from inland termite work. The moisture dynamics, the specific vulnerabilities of post-war tract construction in high-humidity environments, and the subterranean termite activity patterns in Daly City's soils all require direct field experience. We bring SPCB License #9119 and hands-on Peninsula expertise to every Daly City inspection.

Our Fumigation Process in Daly City

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

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 Daly City

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 Daly City

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.
