101 Exterminators performs whole-structure fumigation in San Bruno using Vikane (sulfuryl fluoride). California licensed, SPCB Lic. #9119, a California-licensed business. Fumigation answers one problem: drywood termites spread through framing no other method can reach. In a city with as much attached housing as this one, from the hillside condominium blocks to the newer townhomes near the BART and Caltrain stations, whether tenting is even possible depends on what you own.

Local Context

A Tent Covers a Structure, Not a Unit

Fumigation is a structure treatment. The tarps seal to the foundation of an entire building, the gas fills every void inside it, and everyone in that building leaves for the duration. For a detached house on a Rollingwood or Crestmoor street, that is a straightforward job. For an owner in an attached condominium or townhome it is a building decision, because the neighboring units and the shared attic sit inside the same tent and no single owner can authorize it.

The ground the house sits on matters next. Lots on the west-side slope come with steep driveways, retaining walls and tight side yards, and all three affect crew staging and how the tarp seals at grade. Wind is the other factor. Marine flow through the San Bruno Gap runs strongest in the afternoon, and tarps have to be sealed and weighted against it, which is why we set fumigation dates against the forecast instead of dropping them on a calendar.

Fumigation also only answers drywood termites. It does nothing to a subterranean colony living in soil, which is the more likely finding on the low ground near San Bruno Creek and east toward US-101, and it leaves no residual behind. After aeration the structure is as open to new insects from outside as any other house on the block. If the report says Reticulitermes, tenting is the wrong tool and we will say so.

How We Work in San Bruno

Before we quote a tent in San Bruno we confirm three things: that the finding is drywood and widespread rather than localized, that the structure can actually be sealed, and who has the authority to approve it. On the west-side slope we check driveway grade, overhead lines and side-yard clearance for staging. You get the preparation checklist ahead of tent day, covering food, medications and pet food bagged and plants and pets out of the structure, and re-entry happens only after an independent clearance test reads below threshold.

San Bruno Climate

San Bruno receives marine air and seasonal rain. Fog does not establish subterranean activity.

Housing Stock

San Bruno includes postwar neighborhoods and homes on hillsides below the coastal ridge. The construction and later alterations determine which wood is visible.

Why Local Expertise Matters

In San Bruno, foundation type and any finished lower level determine what an inspector can reach. Ask for the inspected areas, any limits, and the written basis for a treatment recommendation. A separate Section I/Section II report is available on request; the report itself does not decide a transaction’s repair terms.

Warning Signs

When to Ask About Fumigation in San Bruno

We manage the entire fumigation process: pre-fumigation inspection and documentation, structure tenting with certified fumigation tarps, introduction of Vikane fumigant to specified concentration, aeration protocol, post-fumigation clearance testing, and coordination with a certified fumigation clearance company before you return. We also provide bagging requirements and preparation guidance for food, medications, and plants.

How It Works

What to Expect from Fumigation in San Bruno

If you already have a pest inspection report, have it ready when you call. The findings and access to the structure help determine whether fumigation is appropriate.

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

Why Choose 101 Exterminators for Fumigation in San Bruno

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 Bruno

Can one condo unit in San Bruno be fumigated on its own?

No. A tent seals to a whole structure, so an attached condominium or townhome is fumigated as an entire building or not at all. That makes it an association decision rather than an individual one. Owners in that position usually take a different route: a licensed inspection to map exactly where the drywood activity sits, then local treatment by drill-and-inject or borate application in the accessible members. We will tell you plainly what local treatment can and cannot reach.

How much wind is too much to tent a house in San Bruno?

The crew calls it on site, and the marine flow through the gap is why it comes up here more than in most towns. Tarps have to seal at grade and stay sealed for the full exposure period, so sustained afternoon wind can move a start time or a date. That is why San Bruno tents get scheduled against the forecast and confirmed the day before. Moving a tent costs a day. A compromised seal costs the whole treatment.

What happens to the yard and landscaping when a San Bruno house is tented?

Plants touching the structure are the ones at risk, and the tarps are the reason. Shrubs against the walls usually need cutting back or protecting so the tarp can seat cleanly at grade, and anything under the tent has to come out. Lawn and planting beyond the tarp line are generally unaffected, since Vikane dissipates as a gas and leaves no surface residue. We walk the yard with you at the pre-fumigation inspection so there are no surprises on tent day.
