101 Exterminators handles termite control in San Jose as a California-licensed structural pest company — SPCB Lic. #9119, working Santa Clara County since 2005. Drywood termites are established in the pre-1970 framing of Willow Glen, Japantown and the East Side, and the ranch tracts built after the orchards came out carry their own exposure. We inspect the whole structure, put the findings in writing, then treat.

Local Context

Two Termite Species, Two Halves of San Jose's Housing Stock

San Jose's median house dates to the mid-1970s, but the city holds framing from nearly every decade since the 1920s. In Willow Glen, Japantown and the older blocks downtown, Victorian and craftsman houses still stand on their original framing, and western drywood termites (Incisitermes minor) have had that wood for generations. They live entirely inside the member. A colony can work a rafter above Bird Avenue for years before the first pellets of frass land on a windowsill.

The other half of the city is post-war. The orchards that covered Cambrian Park, Berryessa and Evergreen came out in the 1950s and 60s and single-story ranches went up on them, many of them slab-on-grade. There the risk shifts toward subterranean termites (Reticulitermes), which come up through slab cracks, plumbing penetrations and stem walls — most often on lots near Coyote Creek, Los Gatos Creek and the Guadalupe River, where the soil stays damp well past the rainy season.

The climate hides both. San Jose takes about 14.58 inches of rain a year, almost all of it between November and April, so structural wood dries hard through the long summer and damage stays quiet. Winters are mild enough — December highs average near 58°F — that colonies keep working indoors with no dormant stretch. A termite inspection here has to cover both species, because the same San Jose street can put a 1925 bungalow next door to a 1968 ranch.

How We Work in San Jose

We start where San Jose hides termites: the attic framing and eaves on the older central-neighborhood houses, and the stem wall, slab penetrations and garage sill on the post-war tracts. On Spanish Colonial Revival houses we look hard at the rafter tails under the clay tile and the beam ends on the arcaded porch, since that wood sits exposed to weather. Every finding is photographed and separated into Section 1 and Section 2 on a state-compliant WDO report before we recommend any treatment.

San Jose Climate

San Jose's Silicon Valley location produces warm, dry summers (regularly 90–100°F in July–August) and mild winters. The Santa Cruz Mountains to the west create a partial rain shadow, giving San Jose less rainfall than coastal areas. Heat drives insects toward cooler building interiors in summer. The mild winters support year-round cockroach and ant activity without the winter die-off seen in colder climates.

Housing Stock

San Jose has neighborhoods with housing from nearly every decade since the 1920s. Willow Glen, Japantown, and downtown neighborhoods have craftsman and Victorian homes with significant termite histories. Berryessa, Cambrian, and east side neighborhoods have post-war construction (1950s–1970s) with aging pest barriers. North San Jose and newer developments have modern construction. Multi-family housing throughout the city creates bed bug and cockroach transmission pathways between units.

Why Local Expertise Matters

San Jose's diversity — in neighborhood character, housing age, and industry mix — requires a pest control partner with genuine breadth of experience. We bring our 20+ years of service across four Central California counties to San Jose customers, combining urban commercial pest management expertise with the regional knowledge of a company that understands the larger pest ecology of the Santa Clara Valley.

Warning Signs

Signs You Need Termites Service in San Jose

We perform thorough visual inspections of all accessible structural wood, attic spaces, crawl spaces, fencing, and exterior wood. Our reports clearly distinguish Section 1 conditions (active infestations requiring immediate treatment) from Section 2 conditions (conditions that are likely to lead to infestation). We issue California-required WDO reports for real estate transactions and carry the licensing required by the Structural Pest Control Board.

Hollow-sounding wood when tapped — galleries eaten from inside

Frass (fine sawdust-like pellets) near baseboards or windowsills — drywood termite excrement

Discarded wings near doors or windows in spring — swarmers leaving to start new colonies

Blistering or bubbling paint on wood surfaces — subterranean tunnel activity underneath

Mud tubes running up foundation walls or piers — subterranean termite foraging trails

Soft or sagging flooring near walls — severe structural damage to subfloor joists

Small holes in wood with discoloration around the edges

Common Questions

Termite Control FAQs for San Jose

Do San Jose homes get drywood termites, subterranean termites, or both?

Both, and which one you have usually tracks with when the house was built. Drywood termites (Incisitermes minor) dominate the pre-1970 stock around Japantown, Willow Glen and the East Side, living inside the framing and dropping frass. Subterranean termites (Reticulitermes) come from the soil and show as mud tubes on stem walls and piers, and they turn up more often on the slab-built tracts near Coyote Creek and the Guadalupe River. Treatment differs by species, so identification comes first.

When do termites swarm in San Jose?

Drywood swarmers fly in late summer and fall; subterranean swarmers fly after the winter rains. In practice that means San Jose homeowners find discarded wings on a windowsill in September, or after a wet stretch in February or March. Swarmers inside the house mean a colony is already established in or under the structure — not that one just arrived. Save a few wings or insects in a bag; they make species identification straightforward.

My San Jose house is on a slab — can it still have termites?

Yes. Slab-on-grade construction is standard in the ranch tracts built over the old orchards in Cambrian Park, Berryessa and Evergreen, and it does not stop termites. Subterranean termites travel through slab cracks, expansion joints and plumbing penetrations to reach the sill plate and wall framing above. Drywood termites need no soil contact at all — they enter through exposed wood at the eaves, fascia and attic vents.
