In San Diego, CA, termite control comes down to two questions: which termite is it, and where is it feeding? Subterranean termites nest in the soil and move through mud tubes, while drywood termites live inside the timber they consume, so the two call for different methods. Describe what you have seen, for example mud tubes, discarded wings or pinhole-sized frass, using Call Now and our team serving 76 ZIP codes around San Diego will take your call.
Signs of termites in a house
- Bubbling or buckling paint, warped doors and windows that suddenly stick, and soft spots in baseboards
- Mud tubes: pencil-width tunnels of soil on foundation walls, piers or sill plates
- Swarmers: winged termites near windows and lights, usually in spring, and piles of shed wings
- Hollow-sounding or sagging wood that sounds papery when tapped with a screwdriver handle
- Frass: tiny six-sided wood pellets from drywood termites, kicked out of small holes
What a termite inspection should cover
An inspection covers the perimeter of the foundation, the crawl space or the edges of the garage slab, framing in the attic, window and door frames, decks, any fence posts touching the house, and wood that is in contact with the soil. The inspector works with a flashlight, a moisture meter and a probe.
In a home sale, the lender may ask for a wood-destroying insect report. That report records what was seen and what was not accessible. It is not a guarantee about the future.
Termite treatment methods compared
| Method | How it works | Typical use |
|---|---|---|
| Moisture and wood-to-soil fixes | Removing wood contact, repairing leaks and improving drainage | Every case, because it removes what termites need |
| Liquid termiticide (soil trench and rod) | A treated zone in the soil around the foundation stops termites from reaching the structure | Subterranean termites around slab and crawl space foundations |
| Spot and localized wood treatment | Foam, dust or injected product placed into the infested wood | Small drywood infestations in accessible wood |
| Structural fumigation (tenting) | A gas fills the whole structure for a set time while the home is vacated | Widespread drywood termites in several areas of the house |
| Bait stations | Stations in the ground hold a slow-acting bait that workers carry back to the colony | Subterranean termites when soil treatment is hard, or alongside it |
Subterranean, drywood and Formosan termites
Because subterranean termites nest underground and depend on moisture, they construct mud tubes to get up to the wood above the soil, and across much of the country they are the leading wood-destroying insect. Drywood termites take a different route: they get in through attic vents, eaves and cracks, then live wholly inside dry timber and leave frass behind. The Formosan termite, found in Gulf and southeastern states, is an aggressive subterranean species whose colonies grow very large.
Naming the species and pointing out where it is active is the first thing a good company does. Picking a treatment before that identification is guesswork.
What happens after treatment
Treated soil and bait stations work over weeks, not hours, and mud tubes may stay visible even when termites are gone. Our technician should tell you what to watch for, when the next inspection will be, and what any written guarantee does and does not cover.
Do not knock down or scrape active mud tubes ahead of the inspection; a photograph does the job without disturbing the evidence.
Prevent termites around the house
- Fix leaking gutters, hose bibs, AC condensate lines and irrigation spray against the wall
- Seal cracks around pipes and utility penetrations
- Store firewood, lumber and cardboard off the ground and away from the foundation
- Schedule an inspection every year, and after any flood or major plumbing leak
- Keep mulch, soil and plants a few inches below siding and out of contact with wood
Questions to ask before you agree to any termite control
- What will you write down for me: scope, exclusions, follow-up and product list?
- What will you seal, remove or fix, and what stays my job?
- What species or problem did you find, and what did you see that proves it?
- Which products, baits or devices will you use, and where will they go?
- Who is on site, and can you show the state licence or applicator ID for the work?
What makes termite control different in San Diego
Mild year-round weather keeps pests active in all seasons. Argentine ants are a constant in San Diego yards and kitchens; drywood termites are a structural concern.
Roof rats use palms and canyon edges; Norway rats appear near restaurants and the waterfront. Urban canyons and hillsides give pests wildlife corridors close to homes. What works in one climate or housing style can fall flat in the next, so ask us to explain how these local details shape the plan for your property.

Termite Control in San Diego: common questions
When is termite swarm season?
Swarms of winged termites usually appear in spring after warm rain, though timing varies by species and region. A swarm inside the house suggests a mature colony nearby and deserves an inspection soon.
Is termite damage covered by home insurance?
Standard homeowner insurance generally leaves out termite damage on the grounds that it can be prevented with maintenance. Go through your own policy and ask us which problems the treatment guarantee covers.
How do I know if I have termites?
Check foundation walls for mud tubes, windowsills for shed wings, the floor for tiny wood pellets, and any suspect wood by tapping it to hear whether it sounds hollow. Because other insects and moisture damage can look much the same, a professional inspection is what confirms the species and the extent.
Can I treat termites myself?
A whole colony is out of reach for most over-the-counter products. Professional soil treatments and bait systems go in around the structure's perimeter and depend on specialist equipment and label training. Tiny, visible drywood spots are the one place DIY may work, and an inspection should decide whether yours qualifies.
How long does termite treatment last?
A treated zone of soil can keep termites out for years if it is left undisturbed, while bait systems keep protecting only as long as the stations are looked after. How long protection lasts depends on the product, the soil, how the house was built and the inspections that follow. Have the guarantee terms put in writing.
What is the difference between subterranean and drywood termites?
The difference lies in where they live. Subterranean termites nest in the soil and use mud tubes to get to wood, whereas drywood termites stay inside dry wood and push out pellet-like frass. Each is treated differently, which is why the species has to be identified before a product is chosen.
