The Problem

In San Francisco, the risk comes from two directions. Subterranean colonies push up from the soil under San Francisco homes, and drywood swarmers can land on exposed wood and start a new colony in an attic or eave. Either way, the feeding is silent. termites eat paper, cardboard, and the paper facing on drywall, not only lumber and plywood.

•Termite activity reported at a neighbor's home

Treatment Options

Termite Inspection and WDI Report

Typical published range: $75–$250

The best San Francisco inspectors bring a moisture meter, a probe, and patience for tight crawl spaces. The report should separate active infestation from old, treated damage.

60–120 minutesBest: Every job, real estate closings, and yearly peace of mind

Annual Renewal and Monitoring

Typical published range: $150–$400 per year

Renewal fees are small next to a second full treatment. For San Francisco homeowners, the visit usually includes a walk-around, a crawl space check, and a bait station service.

30–60 minutes per visitBest: Keeping a treated home protected after the initial job

Bait Station System with Monitoring

Typical published range: $1,500–$3,500 install, plus $300–$500 per year

Each station holds cellulose bait laced with a chitin synthesis inhibitor. Workers around a San Francisco home share it, cannot molt, and the colony dies over weeks to months.

2–4 hours to install; checked quarterlyBest: Colony elimination, wells and slabs, homes near water

Fumigation for Drywood termites

Typical published range: $1,200–$4,000 (often $1–$4 per square foot)

Fumigation tents the house and fills it with sulfuryl fluoride gas. For San Francisco homes with drywood termites in several areas, it is the only way to reach every gallery.

2–3 days including tenting and aerationBest: Widespread drywood termites throughout a structure

The research on termites in U.S. homes, and what it means in San Francisco

There is no San Francisco-specific termite infestation rate published by any agency, and this page does not invent one; what exists for San Francisco readers is national and regional survey data plus published pricing benchmarks, summarized below with their limits stated plainly. Thirty-six percent of U.S. homeowners in National Pest Management Association (NPMA) and Harris Poll research released March 24, 2026, recognized common signs of a termite infestation, a self-assessed knowledge figure rather than a test of homes actually infested. A homeowner offered a bait-only program is being offered the least common of the three main approaches: 16% of professionals in Pest Control Technology (PCT) magazine's 2025 termite market report (about 145 respondents, 2024 operations) primarily used baits, a professional-practice percentage, not an infestation statistic. The same question comes up in San Francisco: in Pest Control Technology (PCT) magazine's 2025 termite market report (a Readex Research survey of roughly 145 pest-control professionals about 2024 operations), 48% of respondents primarily used baits and liquids together, more than either alone, a figure about how professionals work, not household termite rates. A number that shapes expectations in San Francisco as much as anywhere: some 94% of pest-control company locations offered post-construction termite treatments in Pest Control Technology (PCT) magazine's 2025 termite market report, a BASF-sponsored Readex survey of about 145 professionals covering 2024 operations; the share describes companies, not how many homes have termites. Worth knowing before you call anyone in San Francisco: Forty-four percent of U.S. homeowners ages 25–75 in HomeTeam Pest Defense's March 2022 online survey said they had used a pest-control service, a self-reported figure from a survey sponsored by a pest-control company with an undisclosed sample size. Because every figure above has a stated population and date, you can cite it when comparing San Francisco providers; what none of them can tell you is what your specific San Francisco property needs, and that still takes an on-site inspection.

When to Call a Professional

Call a San Francisco termite professional the moment you see mud tubes on a foundation, live swarmers indoors, or wood that crumbles under a screwdriver. These are not maybe signs. An inspector in San Francisco, California can confirm the species and map how far it has spread. Lenders for VA loans and many conventional loans require a WDI clearance letter from a licensed inspector before closing.

DIY vs Professional

The honest DIY limit for San Francisco homeowners is prevention and monitoring. Retail bait stakes detect termites but rarely eliminate a colony. Professionals in San Francisco use baits with proven active ingredients on a maintained schedule. A full liquid barrier can require dozens of gallons of finished solution trenched around every foot of foundation.

Local Context

Every San Francisco property sits in the same mediterranean climate, but termite pressure still varies block by block with drainage, landscaping, and the age of the house. Activity typically peaks during spring swarm season (March-May), warmer earlier in the South. A provider working in San Francisco should be able to connect these local conditions to what they actually found at your home.

Prevention Tips

✓Inspect used furniture for drywood pellets before bringing indoors
✓Repair rotting trim, fascia, and window frames
✓Use borate-treated or pressure-treated lumber for repairs
✓Keep gutters clean so water does not pool
✓Seal cracks in the foundation and slab
✓Fix leaking hose bibs, faucets, and pipes promptly

Frequently Asked Questions

Why do termite quotes vary so much?

How much does termite fumigation cost?

How much does termite treatment cost?

Most San Francisco homeowners pay in the low thousands. Inspection is $75 to $250, treatment is typically $1,200 to $3,500, and renewal for a San Francisco home is $150 to $400 per year. A larger San Francisco house or a tented drywood job pushes those numbers higher.

Does homeowner insurance pay for termite damage?

Do not count on it. Termite damage to a San Francisco home is excluded from standard policies, and claims are routinely denied. Budget for treatment and any repairs yourself, and ask your San Francisco provider about a damage repair warranty if you want protection.

How long does termite treatment take?

A liquid barrier around a typical San Francisco home takes a half day to a full day. Bait stations take a few hours to install, though colony elimination around a San Francisco home unfolds over weeks or months. Fumigation of a San Francisco house takes two to three days including tenting and aeration.

How long do termite bait stations take to work?

Bait works on the colony's timeline, not yours. After installation around a San Francisco home, workers must find the stations, feed, and share the bait. Colony decline typically takes a few months. Newer baits act faster, and your San Francisco provider can tell you what to expect.

Can termites damage a house on a concrete slab?

A concrete slab slows termites but does not stop them. Around San Francisco, California, foragers follow cracks and pipe penetrations up into the walls. Signs often appear as mud in drywall pinholes or damaged baseboards. A San Francisco provider treats slabs by drilling holes at intervals along the foundation.

Can you treat for termites before building a house?

Yes, and most termite companies offer it.

In San Francisco, ask providers to put the number of visits and any re-treatment terms in writing before work begins.

When is termite swarming season?

For San Francisco, California the relevant figure is this: according to the NPMA/Harris Poll findings released March 24, 2026, fewer than one in four U.S. homeowners, 24%, were aware of termite swarming season; the result measures stated knowledge, not inspection-confirmed activity. Local conditions in San Francisco, California can differ from the survey population, so confirm the specifics with an on-site inspection.
