Which termite species will an inspector name in San Jose?
Five termite species are on California's list, and San Jose can plausibly see several of them. The western subterranean termite is the workhorse pest: UC IPM says Reticulitermes can be encountered in nearly all regions of the state, and it lives in soil colonies that reach a house through ground contact. The western drywood termite is the other one you will hear about constantly. UC IPM calls it California's second most important termite pest and notes it is commonly found along the Pacific coastal region. It flies into wood and lives there with no soil connection. Pacific dampwood termites need consistently wet wood, so they show up in members that have been leaking for a long time rather than in sound framing. Desert subterranean termites and Formosan subterranean termites round out the state list, and the Formosan has been recorded in California by federal and state sources. Ask the inspector to name the species in writing, or to say plainly that identification is pending. That single line on the report determines whether you are pricing soil work or structure work.
A month by month termite calendar for the valley
Winter is watch season. Lows averaging 42 degrees do not stop a subterranean colony underground, and after a genuine soaking storm the ground stays wet long enough to trigger a flight on the next clear afternoon. Spring is the first Reticulitermes window. UC IPM ties California subterranean swarms to clear afternoons in spring or fall following a soaking rain, which is why so many San Jose homeowners find wings on a sunny sill in March or April rather than at dusk. Summer belongs to the daytime fliers. With average highs near 82 degrees and long clear stretches, western drywood swarmers move during daylight through summer and fall, landing on exposed trim, fascia, and open attic vents. That is the season to check vent screens. Fall doubles up: drywood flights continue and the first serious rain can set off a second Reticulitermes swarm. Late summer and fall is also the Pacific dampwood window per Oregon State, which is worth knowing if you have chronically wet wood somewhere on the property.
What the first inspection should actually cover
A real inspection is slow and physical. Expect the inspector to walk the entire exterior with a flashlight and a probe, checking where soil, mulch, concrete, and wood meet, and stopping at every plumbing penetration and hose bib. If there is a subarea, they should go under it. That is where mud tubes on piers, damaged sill plates, and standing moisture actually show up, and a report written without subarea access is an incomplete report. Ask them to say so explicitly if a section was inaccessible. Inside, they will tap and probe baseboards, window and door frames, and any wood that sounds off, and they should look in the attic for pellets and kickout holes on rafters. Bathrooms and laundry areas get extra attention because those are where slow leaks live. You should leave with a written diagram showing where evidence was found, a species finding, a recommended method, and a clear separation between chemical work and any carpentry.
Why San Jose treatment quotes vary so much
The biggest swing is method, not company. A drywood finding priced as a whole-structure fumigation is quoted on the cubic volume of the building, while a subterranean finding priced as a liquid barrier is quoted on linear feet of foundation and how much concrete has to be drilled. Those numbers are not comparable, so if two quotes look wildly different, check whether they even agree on the species. Access drives the rest. Patios, walkways, planters, and hardscape pushed right up to the wall all mean drilling, and drilling means labor. A house with an open dirt perimeter is a cheaper liquid job than an identical house ringed in concrete. Carpentry is the wildcard. Replacing a damaged sill plate or a run of fascia is a separate trade, and some proposals fold it in while others leave it out entirely. In a city where the median home value sits around $1,350,000, it is worth getting repair scope written down rather than assumed. Finally, a bait proposal carries a renewal, so compare the multi-year total, not the first invoice.
Renters, landlords, and who handles a termite finding
termites are a structural issue, which puts them squarely on the owner's side of the ledger in most rental arrangements. Tenants do not control the foundation, the irrigation timer, or the roof, and those are the three things that most often invite a colony in. If you rent in San Jose and find pellets under a window or wings on the sill, report it in writing with photos and the date. Keep a copy. Written notice matters because a fumigation requires the household to vacate for a couple of days and food to be bagged or removed, and that logistics conversation goes better with a paper trail. If you own rental property here, build the inspection into your cycle rather than waiting for a call. A quick perimeter walk each spring, before the Reticulitermes swarm window, catches mud tubes while they are still on the outside of the stem wall. For multi-unit buildings, remember drywood colonies produce their own swarmers indoors, so treating one unit and ignoring the shared attic tends to fail.
How to compare two termite proposals without guessing
Put both proposals side by side and look for four things: the species named, the method proposed, the scope in measurable units, and the follow-up terms. If either document is vague on any of the four, that is your first question back to the company. Check the license branch against the work. California's Structural Pest Control Board issues Branch 1 for fumigation and Branch 3 for control of wood-destroying organisms by insecticides or structural repairs and corrections. A tenting bid from a company without Branch 1 is a problem you want to catch before you sign. Ask what happens after. For a liquid job, ask what the labeled control period is and what the renewal inspection costs. Kentucky extension notes liquid termiticides should control for at least five years when applied to label directions, so a much shorter promise deserves an explanation. Last, ask what is not covered. Repairs, inaccessible areas, and detached structures are the three exclusions that most often surprise people after the work is done.
