A modern craftsman home in a leafy Silicon Valley suburb — Los Gatos, California service area

Fumigation in Los Gatos, CA

101 Exterminators performs full-structure fumigation in Los Gatos using Vikane (sulfuryl fluoride), licensed in California under SPCB Lic. #9119 and working Santa Clara County since 2005. Tenting is what we recommend when drywood termites are established in several separated areas of a structure. That is a common finding in the century-old Victorians and Craftsman homes around Almond Grove, where colonies have had generations to spread through the original framing.

Tight Almond Grove Lots and Steep Hillside Driveways Decide How a Los Gatos Tent Goes Up

Fumigation is a logistics job before it is a chemistry job, and Los Gatos makes the logistics interesting. The Town recognizes five historic districts, and four of them are residential: Almond Grove, University-Edelen, Fairview Plaza and Broadway. Almond Grove was the first and largest subdivision laid out after the Town incorporated in 1887, on narrow lots with houses set close to the property line and mature street trees over the sidewalk. Getting tarps over a two-story Queen Anne in that grid means planning the drop around those trees, the porch details and a neighboring roof that may sit a few feet away.

The hillside neighborhoods present the opposite problem. Homes in Surmont, Belwood, Rinconada Hills and the Kennedy Road hills sit on cut-and-fill pads with steep, narrow driveways and multi-level rooflines that step down the slope. A crew needs staging room for tarps and equipment, and on some of these lots the only flat ground is the driveway itself. We look hard at access before we schedule anything.

The reason tenting comes up so often here is the wood. Western drywood termites (Incisitermes minor) live entirely inside a member and spread by swarming into new pieces, so in a house standing since the 1890s the colonies are frequently in several places at once: a rafter, a header, a stud bay behind plaster and lath. Vikane reaches every void in the structure at the same time, which is exactly what a local treatment cannot do once activity is that distributed.

How We Work in Los Gatos

Before a Los Gatos fumigation we walk the property for access: driveway grade, tree clearance over the roof, the distance to the neighboring structure, and where tarps and equipment can stage. Downtown that usually means a narrow lot and street parking. On the hill it means a sloped, multi-level roofline. We handle the tenting, the Vikane introduction, the aeration protocol and the clearance testing, and you get the bagging list for food, medication and plants well before the day the tarps go on.

Los Gatos Climate

Los Gatos has a sheltered microclimate warmer than much of Silicon Valley in summer — afternoon temperatures regularly reaching 90–98°F — due to the surrounding hills that trap heat. The Santa Cruz Mountains immediately to the south and west moderate winter temperatures and provide slightly above-average rainfall (18–22 inches). The mountain interface creates a temperature inversion that can maintain cooler, more humid conditions in hillside neighborhoods even on hot valley days.

Housing Stock

Los Gatos holds three building eras on one street grid. The Almond Grove Historic District, west of North Santa Cruz Avenue, is Victorian and craftsman work from the 1880s through the 1920s, most of it framed in old-growth redwood and Douglas fir with generous trim, deep eaves, and original single-wall porch construction. The flats east and north of downtown filled in with ranch houses between the 1950s and the 1970s. The hillside lots above town carry custom houses from every decade since, set on posts, piers, and stepped foundations cut into the slope. The 1989 Loma Prieta earthquake matters more to a termite report here than most owners expect, because the repair work that followed opened walls, sistered joists, and replaced sills across much of the older part of town. A single house can hold sound new lumber in one bay and untouched 1890s framing in the next, so what the last inspector found tells you less than usual about what is there now.

Why Local Expertise Matters

The two halves of Los Gatos need different hands. An Almond Grove Victorian needs an inspector who will probe original redwood trim, read the patchwork left by a century of partial treatments and post-earthquake repair, and say which of it is Section 1 and which is a condition. A hillside house needs someone who will get on the roof, follow the branch routes back into the canopy, and close the roofline before anyone places a single bait station, because baiting a house that still has an open highway into the attic just feeds the population. 101 Exterminators, SPCB Lic. #9119, licensed since 2005.

Our Fumigation Process in Los Gatos

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

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 Los Gatos

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 Los Gatos

Can a Victorian in the Almond Grove Historic District be tented without damaging the original details?

Yes. Tenting is a non-destructive treatment, and the tarps rest on the structure rather than being fastened through it. The care on a historic Los Gatos house goes into protecting fragile exterior elements during the drop: decorative bargeboard, finials, porch brackets and old glazing. We identify those in the pre-fumigation walkthrough and pad or route around them. Landscaping tight against the walls is watered heavily beforehand and tied back where it crowds the drop line.

What do I have to do with food and medicine before a Los Gatos fumigation?

Anything meant to be eaten, drunk or taken has to leave the structure or be sealed in the Nylofume bags we provide. That includes an opened box of cereal, pet food, refrigerated and frozen items, prescription and over-the-counter medication, and supplements. Sealed metal cans and unopened glass jars with the factory seal intact can stay. We hand you the full list and the bags at the pre-fumigation visit so you are not sorting the pantry the night before.

Where do people stay while a Los Gatos house is being fumigated?

Somewhere else, for at least one night and usually more. The tent goes on, the gas holds for an exposure period set by the structure and the target species, then the house is aerated and clearance-tested before anyone re-enters, and we give you the dates in writing before any of that starts. Most Los Gatos households book a hotel nearby or stay with family in Campbell or San Jose. Plan for pets and plants too: houseplants come out, and aquariums have to leave the structure entirely.
