If you have owned a home in Long Beach, Seal Beach, or anywhere along the coast for more than a few years, you have probably been told you should get a termite inspection every year. It is fair to wonder whether that is real advice or just something pest control companies say.
The honest answer: in most of the country, an annual inspection is a reasonable precaution. In Southern California, it is closer to genuinely necessary — and the reason has to do with which termites live here and how they behave.
Southern California has two termite problems, not one
Most of the United States deals primarily with subterranean termites, which nest in soil and travel up into a structure. We have those too. But coastal Southern California is also prime territory for drywood termites, and that second species is what changes the math on inspections.
Subterranean termites nest underground and need soil contact and moisture. They build mud tubes up foundation walls to reach wood. Because they leave visible evidence at ground level, a homeowner has a reasonable chance of noticing them.
Drywood termites do not need soil contact at all. They fly directly into exposed wood, seal themselves inside, and live entirely within the timber they are eating. A colony can establish itself in a roof eave, a window frame, an attic rafter, or a garage header and remain completely invisible from inside the house. There are no mud tubes. There is often no sign at all until you see frass, which are the small pellets they push out of the wood.
That second species is why the annual advice is stronger here than it is in most places. You cannot reliably spot drywood termites by living in the house. Nobody can. They are inside the wood.
Why swarm season matters more than the calendar date
Both species send out winged reproductives, called alates, to start new colonies. In Southern California, drywood swarms typically run from late summer into fall, and subterranean swarms tend to follow rain.
This has a practical implication most homeowners miss. If a swarm lands on your house in September and a new colony establishes itself in a rafter, that colony will spend the next several months quietly eating. An inspection timed after swarm season is far more useful than one timed randomly. It catches new activity while the damage is still small.
If you are going to do this once a year, doing it in the fall is more valuable than doing it in the spring.
What actually happens during an inspection
A real termite inspection is not someone glancing at your baseboards. It should cover:
- The attic, including rafters, sheathing, and any exposed framing. This is where drywood colonies are found most often — and it is also where an inspector will notice signs of rodent activity, since the two problems share the same spaces.
- The garage, especially the header above the door and any framing that meets the roofline.
- Eaves, fascia, and trim — the exposed wood a swarm can reach directly.
- The perimeter foundation, checking for subterranean mud tubes.
- The crawlspace or sub-area, if the home has one.
- Window and door frames, particularly on the sun-exposed and weather-exposed sides.
- Any wood-to-soil contact — fence posts, deck supports, planter boxes against the structure.
An inspector is looking for frass, hollow-sounding wood, blistered or bubbled paint, discarded wings near windowsills, mud tubes, and small kick-out holes. We cover these in more detail in our guide to the early warning signs of termites.
The case for skipping it
To be fair, there are situations where an annual inspection is less urgent:
- Your home is newly built and still under a builder’s termite warranty.
- You completed a full fumigation recently and have documentation.
- Your home is entirely slab-on-grade with minimal exposed wood, stucco throughout, and no attic access issues.
Even in those cases, “less urgent” means every two years rather than never. Southern California’s climate does not give any structure a permanent pass.
The case for doing it every year
The stronger argument comes down to how termite damage behaves over time. It does not progress in a straight line — it compounds. A colony that has been active for one year is a localized repair. The same colony after four or five years may have moved through structural framing, and the conversation changes from a treatment to a construction project.
The other factor is real estate. In California, a termite inspection is a routine part of most home sales. Homeowners who have never inspected frequently discover an established problem at the worst possible moment, under escrow deadlines, with a buyer waiting. Finding it on your own schedule is considerably less expensive and less stressful than finding it on a buyer’s.
What to do if an inspection finds something
Not every finding means fumigation. That is the single biggest misconception we run into.
Localized drywood activity confined to an accessible area can often be handled with targeted treatment of the affected wood rather than tenting the entire structure.
Widespread or inaccessible drywood activity across multiple areas is where whole-structure fumigation becomes the appropriate answer, because there is no way to reach every colony individually.
Subterranean activity is treated differently again, typically with soil treatment or a baiting system around the perimeter rather than fumigation at all.
A good inspector should tell you which of these you are dealing with and why. If someone recommends tenting your house without walking you through what they found and where, get a second opinion. Our termite control page explains how each approach works.
How often, in plain terms
For most Southern California homeowners:
- Annually if your home is more than fifteen years old, has an attic, has exposed eaves or wood trim, or has any history of termite activity.
- Every two years if the home is newer, recently treated, or has minimal exposed wood.
- Immediately, regardless of schedule, if you see frass, discarded wings on windowsills, or paint that looks blistered over wood.
Getting your home checked
Dr. Pest provides free termite inspections throughout Long Beach, Seal Beach, Los Alamitos, the South Bay, and Orange County. If we find activity, you get a written report explaining what was found, where, and what the appropriate treatment actually is — before any work is scheduled or quoted.

Frequently asked questions
Are annual termite inspections required by law in California?
No. There is no law requiring homeowners to inspect annually. Inspections are commonly required as a condition of a real estate transaction, and some lenders request them, but there is no ongoing legal obligation for a homeowner.
How long does a termite inspection take?
For a typical single-family home, expect thirty minutes to an hour. Larger homes, or homes with difficult attic and crawlspace access, take longer.
Can I inspect for termites myself?
You can check for the obvious signs — frass, discarded wings, mud tubes at the foundation, hollow-sounding wood. What a homeowner cannot reliably do is assess attic framing and inaccessible areas, which is exactly where drywood colonies tend to establish.
Does homeowners insurance cover termite damage?
Generally no. Standard policies treat termite damage as preventable maintenance rather than a sudden covered loss. This is a large part of why regular inspection matters financially.
What time of year is best for a termite inspection in Southern California?
Fall, after drywood swarm season. A colony that established during a late-summer swarm will be detectable but still small.
