Fumigation in Gilroy, 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 Gilroy and surrounding Santa Clara County.

Why Gilroy 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 swarm actively in Gilroy in February–April — the inland climate amplifies the wet-winter trigger for swarm activity more than in northern Silicon Valley cities. Norway rats from garlic and vegetable fields migrate into residential areas during field operations and harvest. Gophers are endemic in the irrigated residential landscaping and agricultural-adjacent yards. Argentine ants are intense in summer heat. German cockroaches are present in commercial food service throughout the historic downtown and commercial corridors.

Gilroy Climate

Gilroy has the hottest and driest climate in Santa Clara County — summer afternoons regularly reach 98–106°F in July and August, with minimal marine cooling influence given its position at the south end of the valley. Annual rainfall is 14–18 inches, concentrated in winter. The hot, dry summers create extreme pest pressure as all species seek moisture and thermal relief in structures. The wet winters followed by rapid warming produce some of the most intense subterranean termite swarm events in our Santa Clara County service area.

Housing Stock

Gilroy has a historic downtown core with older commercial and residential buildings from the early 20th century, surrounded by suburban development from the 1970s through the 2000s as the city grew rapidly. South Gilroy has newer master-planned communities. Agricultural properties and horse ranches exist at the city edges and in the surrounding South Valley area. The mix of very old, mid-century, and newer construction creates diverse termite and rodent vulnerabilities.

Why Local Expertise Matters

Gilroy's agricultural character creates pest dynamics more similar to our Salinas Valley and San Benito County experience than to the urban Silicon Valley cities. We bring our agricultural-interface expertise from 20 years serving communities on the Monterey County-Santa Clara County agricultural corridor directly to Gilroy customers who face the same field-to-residential pest migration dynamics.

Our Fumigation Process in Gilroy

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

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 Gilroy

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 Gilroy

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.
