What to Expect

What to Expect From Professional Termite Treatment

In California, a licensed termite inspection ends in a standardized Wood-Destroying Organism report: Section 1 for active infestation and existing damage, Section 2 for conditions likely to lead to it. Everything else in professional termite treatment hangs off that document — the inspection of all accessible wood that produces it, the treatment matched to the species it identifies, and the verification that closes it out.

Why Termites Are So Hard to Catch

Termites work from the inside of wood outward, which means the surface often looks fine long after galleries have hollowed the member behind it. Central California hosts all three structural termite species, and the two you are most likely to find in a home behave very differently. Drywood termites live entirely inside the wood they eat — no soil contact, no water source — and a single structure can hold several disconnected colonies at once. Subterranean termites nest in the soil and travel up into framing through mud tubes, so their activity tracks soil moisture rather than the wood itself. Because winters here are mild, neither species goes dormant; activity inside a structure continues year-round. The brief swarm of winged reproductives in spring or late summer is often the only visible event an established colony ever produces — and by the time a colony can swarm, it has typically been present for years.

Signs of Termites and What an Inspection Actually Looks For

The visible signs — piles of equal-length shed wings near windows, six-sided fecal pellets (frass) on sills and attic floors, pencil-width mud tubes on foundation walls, wood that sounds hollow when tapped — each point to a different species and a different problem. A licensed inspector reads that evidence systematically: the attic for drywood activity, the crawl space for mud tubes and moisture conditions, the exterior perimeter for earth-to-wood contact, probing suspect wood for hidden galleries. In California, findings go into a standardized Wood-Destroying Organism report that separates Section 1 conditions (active infestation or existing damage) from Section 2 conditions (situations likely to lead to infestation). Inspectors are also required to note any areas they could not access, so you know exactly what the report does and does not cover.

How the Treatment Decision Gets Made

Treatment method follows from two findings: which species is present and how far the activity extends. A localized drywood infestation in accessible wood may be a candidate for direct wood treatment; drywood activity distributed through a structure generally points toward whole-structure fumigation, because a fumigant gas can reach voids that surface treatments cannot. Subterranean termites are treated at the soil, where the colony actually lives — treating the wood alone leaves the source untouched. This is why matching the treatment to the species matters so much: the right treatment for the wrong species accomplishes nothing. It is also why over-the-counter sprays fall short — surface products cannot reach galleries deep inside wood or colonies below ground, and disturbing mud tubes before an inspection can push activity deeper into the structure. In California, structural termite work is restricted to companies licensed by the Structural Pest Control Board.

Our Process

How It Works, Step by Step

Swarmers, Wings, and Mud Tubes
The process generally starts with what you've observed — swarming insects, shed wings, pellet piles, mud tubes, or damaged wood — and where and when you saw it. Photos of the evidence are genuinely useful here. That context tells the inspector which species to suspect and where to begin looking.
Probing the Accessible Wood
A licensed inspector examines all accessible areas — attic framing, crawl space, exterior perimeter, garage, and interior wood — probing suspect members for hidden galleries. A thorough residential inspection generally takes an hour or more, depending on the size of the structure and how accessible the attic and subarea are.
The Report: Section 1 and Section 2
Findings are documented in writing, identifying the species present, the extent of activity, and any conducive conditions. In California's standard format, active infestation or damage is classified as Section 1, while conditions likely to lead to infestation are Section 2 — a distinction that matters most in real estate transactions.
Wood, Soil, or Whole Structure
The recommended method depends on what was found: localized wood treatment for contained, accessible drywood activity; whole-structure fumigation for widespread drywood infestation; soil-applied treatment for subterranean colonies. Fumigation typically spans several days from preparation through aeration and re-entry clearance; most localized treatments do not require vacating. Specifics vary by property.
Confirming the Work, Certifying Completion
After treatment, the treated areas are re-examined to confirm the work addressed what the report identified. For Section 1 conditions, this is when completion documentation is issued. Because termite pressure in this region is continuous, periodic re-inspection remains the most reliable way to catch new activity while it is still small.

Local Knowledge

All Three Termite Species, One Region

Unlike most inland California counties, where subterranean termites dominate, this coastal region supports all three structural termite species — drywood, subterranean, and dampwood — side by side. The coastal fog belt keeps humidity high and temperatures mild enough that colonies stay active twelve months a year, and the pre-1960 housing stock in Monterey, Pacific Grove, Carmel, and older Salinas neighborhoods was framed with old-growth fir and redwood that drywood colonies can exploit for decades. Meanwhile, irrigated soil on the Salinas Valley floor and the clay soils of San Benito County favor subterranean activity, and moisture-affected structures in Santa Cruz County's redwood zones see dampwood termites. This is why species identification comes before any treatment discussion here — the same house can host more than one problem at once.

Common Questions

Good to Know

Do I need to leave my home during termite treatment?

It depends on the method. Most localized treatments — direct wood treatments applied to contained, accessible infestations — generally allow you to stay in the home. Whole-structure fumigation is different: the building is tented and everyone, including pets, must be out for the full process, which typically spans several days from preparation through aeration and re-entry clearance. Your inspector will explain what applies to your situation, since requirements depend on the treatment recommended.

What if the inspection finds more than one termite species?

It happens more often than people expect in this region — for example, drywood activity in the attic framing and subterranean activity in the crawl space of the same house. Because the species live differently, each requires its own treatment approach: what resolves a drywood infestation does not reach a colony living in the soil. A thorough report documents every species found so the plan can address each one rather than only the most obvious one.

Does seeing swarmers mean my house is infested?

Not necessarily. Swarmers are weak fliers searching for new nesting sites, and they can drift in from a colony nearby. Swarmers emerging from your own walls, windowsills, or attic — or piles of equal-length shed wings indoors — are a stronger indicator of an established colony in the structure, since colonies only produce winged reproductives after maturing over several years. An inspection is what determines where the swarm originated and whether treatment is needed.
