A termite inspection exists to answer one question before anyone spends money on treatment: which termite is it? San Diego County has two that matter, they live completely differently, and they are not treated the same way. Guessing wrong wastes the job.

Call 619-277-4796 to arrange an inspection.


The two you are choosing between

Drywood termites

The western drywood termite nests inside the wood itself and needs no contact with soil at all. That is why it turns up in places a soil treatment could never reach: attic sheathing and rafters, fascia, eaves, window and door frames, trim and siding.

Colonies are small, usually fewer than a thousand insects, and they mature slowly over years. A single structure can hold several separate colonies at once, and an infestation found today may well have started five or ten years ago.

What you can actually see: fecal pellets with six flat sides, which nothing else produces, pushed out through kick-out holes under two millimeters across.

Subterranean termites

The western subterranean termite needs soil contact and moisture, and maintains a connection to the ground. Statewide, UC identifies subterranean termites as California's most destructive termite, and they occur in nearly every region of the state.

What you can actually see: mud shelter tubes running up a foundation, a pier or through a crawl space. Damage follows the wood grain and is contaminated with soil, which looks quite different from the clean galleries drywood termites leave.

They are favored by wood in direct contact with soil, damp crawl spaces, leaking plumbing and poor drainage. The general benchmark is keeping structural wood at least twelve inches clear of soil.


One thing you can do before we arrive

If you have found a small pile of what looks like coffee grounds or sawdust, sweep it up and check the same spot again a few days later.

Fresh pellets mean the colony above is active. No new pellets suggests old activity. That single step tells us a great deal before the inspection starts, and it costs nothing.


What we inspect

  • Substructure. Crawl space where accessible: piers, sill plates, subfloor, wood-to-soil contact, moisture and drainage.
  • Attic and roof structure. Sheathing, rafters, and the fascia and eave line where drywood activity concentrates.
  • Exterior. Grade level, siding, trim, window and door frames, decks, fences and any wood touching soil.
  • Interior. Accessible woodwork, sills, door frames, and any area where evidence has been reported.
  • Conducive conditions. The things that invite the problem back even after treatment: drainage, irrigation against the foundation, stored wood, and ventilation.

Where access is unsafe or blocked, we will tell you that rather than guess. An honest note about what could not be reached is more useful than a report that implies the whole structure was seen.


The La Mesa footnote

Worth knowing, and worth keeping in proportion. In February 1992 the Formosan subterranean termite was found in La Mesa, the first non-native termite established in California. The eradication program lost its funding in 1997 and the same population was confirmed again in 2018, about a third of a mile from the original site.

Every confirmed colony in the published record sits within a very small area, and UC's own language is that it remains restricted to a small pocket. Most La Mesa homes will never encounter one, and the overwhelming majority of termite work anywhere in this county is ordinary drywood and western subterranean work.

What it does change is one practical thing. Formosan swarmers fly at dusk and are drawn to lights, roughly late May to early August. Our native subterranean termites swarm in daylight, on clear afternoons after rain. An evening swarm around a porch light in early summer is worth identifying rather than assuming, and it is the reason we identify species rather than guess.


When to book one

  • Buying or selling. You want to know before the decision, not after.
  • You have seen swarmers or wings. A scatter of discarded wings on a sill is worth a look.
  • You have found pellets. Do the sweep-and-recheck test first, then call.
  • The house is old and has never been inspected. Drywood colonies stay hidden while they mature, so no visible evidence is not the same as no termites.
  • You are planning structural work. Better to know what is in the wood before it is opened up or closed in.

Common questions

How do I tell the difference myself?

Six-sided pellets and small kick-out holes in above-ground wood point to drywood. Mud tubes on a foundation point to subterranean. If you have both, that is possible too.

My house is stucco. Can it still have termites?

Yes. Stucco is a finish over wood framing. Drywood termites live inside that framing without ever touching soil, so the stucco hides the evidence rather than preventing the problem.

Nothing has ever been found in eighty years. Do I need this?

Colonies mature slowly and stay concealed while they do, so absence of evidence is not evidence of absence. Age and exposed wood are the two factors that matter most.

Will an inspection find everything?

No inspection can see inside every wall and void, and we will not pretend otherwise. What it does is establish what is present where it can be reached, identify the species, and record the conditions that make recurrence likely.
