Are Annual Termite Inspections Necessary? An Honest Answer for Southern California Homes
You might expect a company that sells an annual termite program to say yes. The honest answer is that it depends on your house, and here is how to tell.
No law requires a yearly termite inspection, and not every home needs one. A yearly inspection is worth it if you are keeping a termite warranty active, if the house has had a localized drywood treatment, if it has in-ground bait stations, or if it is an older home with a lot of exposed wood in drywood country like the San Gabriel Valley. For an older valley home with no warranty to keep, we recommend every two or three years. The University of California’s general guidance is every 3 to 5 years, and every several years for homes with a history of subterranean termites. Between inspections, a few minutes looking for pellets, mud tubes and wings goes a long way.

How often, by situation
Find the line that fits your house:
| Your situation | How often | Why |
|---|---|---|
| Keeping a termite warranty active | Every year | Renewable termite warranties usually depend on a yearly visit; ours extends a localized treatment’s two-year warranty another year at each annual visit |
| Had a localized (spot) drywood treatment | Every year | A localized treatment can’t guarantee every hidden colony was reached; the University of California suggests considering an annual inspection service |
| In-ground bait stations around the house | Every year, with the station service | Stations only protect the house if someone checks and services them |
| Older home with exposed eaves and trim, no warranty | Every 2 to 3 years | Decades of exposed wood plus drywood and subterranean pressure; colonies grow for years before they show |
| Had subterranean termites before | At least every few years; yearly with bait stations | The University of California notes these homes are especially vulnerable to reinfestation |
| Newer stucco home, little exposed wood, no termite history | Every 3 to 5 years | The University of California’s general guidance for catching infestations before they become damaging |
| You are seeing pellets, mud tubes or swarmers now | Now | Signs mean the schedule no longer applies |
Are termite inspections required every year?
No. California law sets the minimum standard for how a termite inspection is done, including a visual search of the accessible areas, and it requires an inspection before any termite treatment. It doesn’t require homeowners to have their house inspected on any schedule. When a yearly visit is required, it is because a warranty or service agreement says so.
When a yearly inspection pays for itself
When there is a warranty to keep. Our localized drywood treatments carry a two-year written warranty, and each visit on the annual termite program extends it another year. Skip visits and the warranty runs down; let it lapse and new activity becomes a new job. If you are paying for a warranty, the yearly visit is what keeps it alive (more in termite warranty explained).
When the house keeps getting new chances to be infested. Drywood termites swarm here every year, so new colonies keep arriving on older houses with a lot of exposed wood. A colony caught in its first year is a couple of drill holes; the same colony found years later can mean wood repairs.
After a localized treatment. The University of California notes that no one can be certain a localized treatment reached every colony in a house, and it suggests considering an annual inspection service. A yearly look is how a missed colony gets caught small.
When every few years is enough
A newer stucco home with little exposed wood, no termite history and no warranty to keep doesn’t need a yearly visit. The University of California’s general guidance is an inspection every 3 to 5 years to catch infestations before they become damaging. For older valley homes with exposed eaves, trim and raised foundations, we recommend every two or three years instead. If your house belongs in the every-few-years group, we will tell you that rather than sell you a yearly plan.
What a real inspection covers
Whatever the schedule, an inspection is only worth it if it is thorough. It should cover the eaves, fascia and exterior trim, the foundation line for mud tubes, the garage, window and door frames, the attic, and the crawlspace if there is one, with any area that couldn’t be reached listed as inaccessible. Here is what a real termite inspection covers, and how to read the report.
What to check yourself between inspections
- Sills, floors and the garage slab for small piles of pellets; sweep them up and look again in a few days
- The foundation, piers and slab edges for mud tubes
- Window sills and light fixtures for shed wings after warm days in spring and late summer (here is when flying termites matter)
- Eaves, trim and patio covers for blistered paint or wood that sounds hollow
- Sprinklers and leaks that keep wood or stucco wet
See the signs of termites guide for what each one looks like.
What our annual program includes
One scheduled visit a year: a full inspection of the structure, treatment attention wherever new activity turns up, service of any in-ground bait stations, and a written warranty extended another year. The renewal date lives on our calendar, not yours. Most visits are timed for late fall or winter, after swarm season, when fresh wings and pellets mark where activity is (more in the best time of year for termite treatment).

Common Questions
Quick Answers.
Are annual termite inspections necessary?
Not for every home. They are worth it if you are keeping a termite warranty active, after a localized drywood treatment, with in-ground bait stations, or for an older home with a lot of exposed wood. Otherwise every two to five years is reasonable, depending on the house.
How often should you get a termite inspection in Southern California?
Every year if you have a warranty to keep, bait stations or a past localized treatment; every two or three years for an older home with exposed eaves and trim; and every 3 to 5 years for a newer home with no termite history, which matches the University of California’s general guidance. Any time you see signs, do not wait for the schedule.
Does California require yearly termite inspections?
No. California law sets the minimum standard for how a termite inspection is done and requires an inspection before termite treatment, but it does not require homeowners to have their house inspected on a schedule. A yearly visit is required only when a warranty or service agreement says so.
Does a termite warranty require an annual inspection?
Usually, if you want it to keep going. Renewable termite warranties generally depend on a yearly visit. Ours works that way: each annual program visit extends a localized treatment’s two-year warranty another year. Read the renewal terms in your agreement.
What happens if I skip a year of termite inspections?
If you have a warranty, it runs down without the visit that extends it, and if it lapses, new activity becomes a new job. Without a warranty, the cost of skipping is time: colonies keep growing quietly until they show.
Do newer homes need termite inspections?
Less often. A newer home with little exposed wood and no termite history can follow the University of California’s general guidance of every 3 to 5 years. Drywood swarmers can still reach exposed wood under the eaves and in the attic, so do not skip it entirely.
Can I inspect for termites myself?
You can check the easy places between inspections: sills, floors, the garage slab, the foundation and the eaves. A professional inspection goes into the attic and crawlspace and sounds and probes the wood, and the University of California recommends a licensed professional because termite signs are often in dark, hard-to-reach places.
When is the best time of year for a termite inspection?
After swarm season is the most informative time, because fresh wings and pellets mark where activity is; for most San Gabriel Valley homes that means late fall or winter. If you find a sign, the best time is now.
Is a yearly termite inspection worth it?
It is when there is something to protect: a warranty, a past treatment, bait stations or an older house with a lot of exposed wood. For a newer house with no history, an inspection every few years and your own quick checks in between are a reasonable plan.
