Homeowners, landlords and anyone buying or selling a house in San Jose, whether you've spotted something or just want to know what to watch for.
What to look for
Termites work quietly. A colony can feed inside a wall for years. Winters around San Jose stay mild, with average lows near 42°F, so colonies keep feeding all year. Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs.
- 1Blistered or bubbling paint on wood surfaces.
- 2Screwdriver sinks easily into sills or trim.
- 3Piles of identical shed wings on windowsills.
- 4Small kick-out holes in exposed wood.
- 5Live pale insects inside a broken mud tube.
- 6Winged swarmers indoors, especially in spring.
Why it’s worth acting soon
- Colonies grow and spread every year they go untreated.
- Damage hides behind drywall, flooring and trim.
- Homeowners insurance usually doesn’t cover termite damage.
- An active infestation can complicate a home sale.

Local termites conditions in San Jose.
San Jose sits in a mediterranean climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south. In San Jose, the area is mostly urban, so termites pressure can differ from one block to the next depending on how tight the entry points are and how much food, water, or shelter is close by. An inspection in San Jose usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing San Jose's seasonal timing lets you schedule treatment before the busy stretch rather than after it, which usually means faster service and a more accurate quote. A provider who works San Jose and California every day can point out the specific conditions that matter most here, and getting the scope, price, and follow-up terms in writing makes it easier to compare options.
Subterranean termites don't stop in winter; they just go deeper. A quiet season is a good time for a non-urgent inspection.Which termites live around San Jose.
The termite you're most likely to meet in San Jose is the western subterranean termite. It nests in soil and builds mud tubes to reach wood. It needs steady moisture. Drywood termites are common around San Jose as well, flying straight into attic framing, eaves and furniture without any soil contact. Look for tiny piles of pellets that look like coarse sand.
When termites swarm here.
Swarm season is when termites show themselves. In San Jose, western subterranean termites usually swarm in spring, and again in fall after the first good rain. Drywood termites around San Jose tend to swarm in late summer and fall. A swarm outside means a colony is nearby. A swarm inside usually means it's in the house. Save a few in a bag, or snap a clear photo.
Where to look around your house.
Plenty of homes in San Jose have basements, so check where the wood framing sits on top of the foundation wall. Look around window wells and unfinished walls. Outside, check porches, steps and decks that touch soil. Wood should stay several inches above the ground. The same advice applies across the area, from San Jose out to Sunnyvale and Fremont.
A year of termites in San Jose.
- Spring and fall: swarm seasons. In San Jose, swarms often follow the first warm days and the first fall rain. - Summer: with highs around 82°F in San Jose, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 17 inches of rain a year in San Jose, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in San Jose, before swarm season starts.
Ways to keep the cost down.
- Get two or three quotes, and compare what each one covers. - Fix leaks and drainage first. Moisture brings termites back. - Ask about both bait and liquid options for your house. - If you already have a warranty, keep the renewal current. - Book before swarm season, when schedules fill up.
What happens at an inspection.
Most inspections take an hour or two. The inspector walks the outside of the house first. They check the foundation, the soil line and nearby wood. Inside, they check the garage, baseboards, plumbing gaps and the attic. They'll check the basement walls and sill plate. A moisture meter and a probe help them find hidden activity. Afterward, ask them to show you what they found. Photos help.
Termites or ants?
- Wings: termite wings are all the same length. Ant wings aren’t. - Waist: termites are thick through the middle. Ants are pinched. - Antennae: termite antennae are straight. Ant antennae bend like an elbow. - Debris: termites leave mud. Carpenter ants leave sawdust. - Tunnels: termite galleries are packed with mud. Ant tunnels are clean and smooth.
Getting ready for treatment day.
Soil treatments and bait stations need little prep. Clear a path along the outside walls. Move stored boxes away from garage walls. Mark sprinkler heads and any buried lines. Keep pets and kids inside while the crew works outside. Ask how long to stay off treated soil. Any drill holes in a slab or patio get patched.
Mulch and termites.
Keep mulch thin and pull it back from the foundation. A dry strip along the house lets you spot mud tubes. Wood chips right against siding hold moisture termites like.
Questions to ask before you sign.
- Which termites did you find, and where? - What product or system will you use? - Is the whole foundation treated, or just one spot? - What does the warranty cover, and for how long? - What does the yearly renewal cost? - What do I need to do before and after treatment?
What affects the price
- Warranty type: retreatment only or damage repair.
- Annual renewal and monitoring fees.
- Time of year and how booked up local companies are.
- Number of bait stations required.
- Attached garages, decks, and additions.
- Local labor rates and licensing requirements.
- Slab, crawl space, or basement construction.
- Cubic footage under the tent for fumigation.

What's your biggest concern about termite control costs?
When to call for help
Call if you see mud tubes, pellets or an indoor swarm. Hollow-sounding wood is another clue. Buying or selling? Get a wood-destroying insect (WDI) report either way. Lenders often ask for one. It's also the cheapest termite service. Carpenter ants leave clean tunnels and sawdust. Termites leave mud.
What you can do yourself
Treating an active colony is harder. The product has to reach the whole colony. It also needs even coverage around the entire foundation. Store-bought sprays usually kill only the termites you see. Some of the work is yours. Pull mulch back from the foundation. Fix leaks and clear gutters. Keep firewood away from the house.
Termites in San Jose
San Jose only sees about 17 inches of rain a year, so local termites gather wherever water collects, like sprinkler zones, hose bibs and AC drain lines. Termite activity in California is above average. Most houses will see termites at some point. With summer highs around 82°F, San Jose's mediterranean climate decides when local termites are busiest. A typical home in San Jose is worth around $1,350k, which puts a few hundred dollars for an inspection and prevention in perspective.

Usually $75–$250. Some companies credit it toward treatment if you go ahead. It's worth asking.
Why do termite quotes vary so much?
Companies measure differently and use different products. Some include a warranty or yearly checks. Drilling through concrete adds labor. Compare what's included, line by line.
Do I have to leave my house during termite treatment?
Not for a soil treatment or bait stations. Fumigation is different. Everyone leaves for two to three days, pets and houseplants included.
What does a WDI report include?
It lists any termites or damage found. It also notes conditions that invite them, like wood touching soil. It only covers areas the inspector could reach.
Does fumigation kill subterranean termites too?
Not reliably. Tenting clears termites inside the house. It doesn't reach a colony living in the soil.
Do most homeowners know termites can damage their house?
In San Jose, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. In San Jose, a professional inspection looks for mud tubes, damaged wood, and swarming activity, and treatment targets the soil and the colony rather than just the visible wood.
Are termites common in California?
Around San Jose, the usual culprit is the western subterranean termite.
