The short version
Termite treatment in Los Angeles falls into two families. Drywood infestations are handled by whole structure fumigation, heat, or localized treatment of infested wood. Subterranean colonies are handled by a liquid soil barrier or an in ground bait system. Because UC IPM notes drywood control products are not sold to the general public in California, every one of these is licensed professional work.
- Termite damage in Los Angeles is slow, hidden, and rarely covered by insurance.
- Drywood termites in a Los Angeles home need wood treatment or fumigation, not soil treatment.
- Typical published ranges put whole-home treatment in Los Angeles between $1,200 and $3,500.
If you have not had anything identified yet, get that done before reading the price sections. Condo owners coordinating with neighbors will want the shared structure notes. Written for Los Angeles homeowners who already have an inspection result and are choosing between proposals, owners deciding whether tenting is necessary, and sellers who need work completed before a closing date.
What to look for
The reason there is no single termite treatment in Los Angeles is that the local species live in fundamentally different places. UC IPM describes the western drywood termite as California's second most important termite pest, commonly found along the Pacific coastal region, and it lives entirely inside dry wood with no ground contact. Reticulitermes, the western subterranean group, can be encountered in nearly all regions of the state and lives in soil. That difference decides which treatments can physically reach the insects. A treated soil zone is a wall a soil dwelling forager has to cross, which is useless against a colony inside an attic rafter. Fumigant gas penetrates wood throughout a sealed structure, which does nothing about a colony living in the yard. Los Angeles conditions extend the working season for both. Winter lows averaging around 48F never shut anything down, average humidity near 71 percent keeps exterior wood conditioned, and 15 inches of annual rainfall means subterranean swarming clusters around a few wet stretches rather than a long spring.
- 1Pellet piles that keep coming back in the same spot after you sweep them up, which suggests active drywood feeding above.
- 2New kick out holes appearing in fascia or a door casing that were not there last season.
- 3Fresh mud tubes rebuilt within days after you knocked the old ones off a stem wall.
- 4Swarmers appearing indoors, which means the colony is inside the structure rather than in the neighborhood.
- 5Wood that has gone hollow along an eave or patio cover and flexes under hand pressure.
- 6Paint blistering in a line along trim, with only a paper thin surface left over the damage.
- 7Damage appearing in a second area of the house after a previous localized treatment.
Why it’s worth acting soon
- Buying a narrower treatment than the infestation warrants often means paying twice within a couple of years.
- Scheduling matters in a sale, and fumigation requires days of displacement that a tight escrow may not allow.
- With Los Angeles median home value near $912,000, deferring treatment risks structural repair costs on an expensive asset.
- Drywood colonies reproduce inside a structure, so untreated areas can seed new infestations in the same roof.
- Skipping the repair of damaged wood leaves weakened members in place even after the insects are gone.

Termite Activity by Season
Spring
Activity begins as temperatures rise.
Summer
Peak season — populations grow fast.
Fall
Pests seek shelter; prevention matters.
Winter
Reduced activity; indoor risk remains.
Treatment options and typical costs
Termite Inspection and WDI Report
$75–$250
For a sale or refinance in Los Angeles, lenders often want a WDI report dated within a month or so. The report notes live termites, past damage, and needed repairs.
- Time
- 60–120 minutes
- Best for
- Every job, real estate closings, and yearly peace of mind
Liquid Soil Termiticide Barrier
$1,200–$3,500 (often $3–$16 per linear foot)
The label on the termiticide is federal law, so a licensed Los Angeles applicator follows it exactly. Ask which active ingredient is used and how long it lasts.
- Time
- Half a day to a full day
- Best for
- Active subterranean termites; fast knockdown around the foundation
Bait Station System with Monitoring
$1,500–$3,500 install, plus $300–$500 per year
Baiting is slower than a liquid barrier but reaches deeper colonies. For a Los Angeles home on a well or with a finished slab, it is often the cleaner option.
- Time
- 2–4 hours to install; checked quarterly
- Best for
- Colony elimination, wells and slabs, homes near water
Localized Wood, Foam, and Borate Treatment
$250–$1,500
Foam termiticide is injected into wall voids liquid cannot reach. Across Los Angeles, California this pairs well with a soil barrier around tricky slab construction.
- Time
- 1–3 hours
- Best for
- Small drywood spots, wall voids, and exposed framing
Prices are typical published ranges. Ask what’s included before you compare quotes.
A slow leak under a sink keeps the wood damp, and damp wood is exactly what termites are looking for.What fumigation day actually looks like.
Before the date, you will get a preparation list. Food, medicine, and some other consumables must be removed or sealed in supplied bags. Plants come out. Pets and people leave, including anyone in an attached unit. The company will want to know about roof condition, since tarps need a structure they can seal, and about access to every side of the building. On day one, crews tarp the house, seal it, and introduce the fumigant. Warning signage goes up and the structure is secured. In a dense Los Angeles neighborhood, expect conversations about parking, side yard access, and where equipment stages. On the following days the gas works through the wood, then the structure is aerated and tested before it is released. You do not go back in until clearance is issued. Ask in advance who is responsible for the roof if tarps damage tile or aging composition, and what documentation you receive at the end. That paperwork matters in a sale. Fumigation is more of a logistics project than a service visit, and knowing the sequence removes most of the anxiety.
When localized treatment is enough and when it is not.
A localized treatment with a scheduled reinspection is a reasonable plan. Also ask about follow up. Look for a described inspection process rather than a shrug. The honest question to ask a company recommending localized work is how they satisfied themselves that nothing else is active. Drywood colonies swarm internally, and a colony you never found keeps working regardless of what happened to the one you did. It stops fitting when evidence turns up in more than one area, when framing is hidden behind finishes, or when the attic cannot be fully inspected. The wood is drilled and treated directly, and adjacent accessible wood may get a borate application. It fits when the infestation is confined and reachable: one door frame, a short run of fascia, a single beam in a garage, discovered early with no evidence anywhere else. Localized drywood treatment is appealing because nobody leaves the house, and it is the right answer in a narrow set of cases. A localized treatment with no follow up is a gamble on the inspector having found everything on one visit.
A downspout that dumps water at the foundation keeps the soil wet year-round. Extend it well away from the house.Choosing between a soil barrier and bait stations.
A liquid barrier is fast. Soil is trenched, concrete is drilled where walkways, patios, and garage slabs block access, and the treated zone stops foragers crossing it. On a typical slab home with hardscape close to the walls, expect drilling to be a real part of the job, and expect patched holes afterward. Baiting is slow and quiet. Stations go in the soil, get serviced on a schedule, and the colony declines over months. Nothing is cut. Because western subterranean termites in this region may swarm at any time of year, the running record of station activity is genuinely informative rather than decorative. University of Florida guidance is direct that bait protection continues only while stations are maintained, so treat the annual service cost as part of the price rather than an add on. If a closing date is driving you, ask which option can be completed and documented within your window. That question usually answers itself. If your Los Angeles inspection found subterranean activity rather than drywood, the choice narrows to two approaches with genuinely different profiles.
What you are responsible for before and after treatment.
Then close the loop on conditions: seal the bare wood that let swarmers in, screen the vents, and fix the irrigation that kept soil damp. Keep the completion documentation with your property records. Sweep areas where pellets accumulated and check them again in a few weeks, because a fresh pile is the clearest sign that something was missed. Afterward, the work is verification and maintenance. Before a soil barrier, move vehicles, pull back planters and stored items along the perimeter, and expect landscaping near the wall to be disturbed. Clearing stored belongings away from garage walls and attic hatches also helps the crew reach what they need. Before a whole structure treatment, that means the preparation list: food and medicine removed or bagged, plants out, pets arranged, access provided to every exterior side, and interior doors and cabinets often left open. Every termite method here comes with homeowner tasks, and missing them is the most common cause of delays. Treatment resets the clock, and maintenance is what keeps it from running out early.
Verifying the work and planning the follow up.
Start with the paperwork. You should have a document stating what was treated, by what method, on what date, under which license branch, and what the company's obligations are if activity reappears. In a Los Angeles transaction that document has resale value, so keep it filed rather than loose. Next, set a reinspection interval. If your proposal included reinspections, put them on a calendar rather than waiting for a reminder. If it did not, decide what you will pay annually and treat it as part of the total cost. Then build the seasonal habit. Check under the eaves and along the garage door frame during summer and fall, when drywood swarmers fly in daylight. Check the foundation and stem wall after the first soaking rain of the season, when California Reticulitermes flights follow. repair what was damaged. Killing a colony does not restore a rafter tail, and weathered damaged wood on an exterior in this climate deteriorates quickly on its own. The end of a treatment is not the end of the job, and a few habits keep you from paying for the same problem twice.
What affects the price
- The volume being treated, since fumigation and heat are priced against the size of the space rather than the number of insects.
- How much of the structure is attached to neighbors, because shared framing has to be treated as one unit.
- Roof and exterior condition, since tarps require a structure that can be sealed and some repairs must happen first.
- The number of separate areas needing localized treatment, which adds up quickly past two or three.
- Concrete drilling and patching for soil barriers where walkways and patios sit against the foundation.
- Displacement costs you absorb yourself, including lodging and food removal during a fumigation.
- Follow up terms: how many reinspections are included and what a renewal costs after the first period.

What's your biggest concern about termites?
When to call for help
Bring in a licensed company before choosing a method, not after. UC IPM notes that termite control products for drywood termites are not available to the general public in California, so the practical choice is between professional methods rather than between doing it yourself and hiring out. early if a Los Angeles sale is involved, because fumigation dates book out and the treatment itself takes days you may not have late in escrow. Ask which license branch covers the work, whether any of it will be subcontracted, and who signs the completion paperwork. Then ask what the company would do if activity reappeared inside the coverage period.
What you can do yourself
What a homeowner cannot do is treat. Fumigation is licensed separately in California, drywood products are not sold to the public, heat treatment requires equipment and monitoring, and a soil barrier fails if it is not continuous. Spraying a can into a kick out hole reaches a few insects in one gallery and leaves the colony intact. Spend your effort on sealing and water, and buy the treatment. The honest split here is that homeowners handle conditions and professionals handle treatment. Sealing bare exterior wood is genuinely preventive work, since a drywood swarmer that lands on painted, sound trim has a much harder time getting started. Screening attic and gable vents does the same job. Correcting irrigation that soaks a foundation and pulling planting beds down below the stucco weep screed reduces subterranean pressure.
Termites in Los Angeles
With a median home value near $912,000, the arithmetic of prevention and prompt treatment is easier than in most markets, and buyers routinely expect documentation that termite work was completed. Humidity averaging 71 percent near the coast is the detail that keeps exterior wood attractive to drywood swarmers, which is why sealing eaves and fascia is treated as maintenance here rather than as optional. Average summer highs near 84F, winter lows around 48F, and just 15 inches of annual rain mean there is no dormant season to wait out, and work gets scheduled year round. Climate extends the treatment calendar rather than limiting it. Fumigation in that setting takes coordination that a rural property never needs. The city holds about 3,822,000 people at urban density, which means tight side yards, shared driveways, and neighbors within arm's reach of a tarp line. Los Angeles gives termite treatment a distinctive set of constraints.

When termites are busiest around Los Angeles
Reticulitermes swarm in the afternoon in spring or fall on clear days after a soaking rain; drywood swarmers fly in daytime during summer and fall; Heterotermes aureus flies late afternoon/early evening in July–September (UC IPM).
UC IPM: Reticulitermes 'can be encountered in nearly all regions of the state'; the western drywood termite is 'California's second most important termite pest', found along the Pacific coast, Central Valley and Southern California deserts. FDACS lists California among states with Formosan termites. Branch 3 covers 'the control of wood-destroying pests or organisms by the use of insecticides or structural repairs and corrections'; Branch 1 covers fumigation.

Simple ways to keep termites away
- Repaint or seal weathered eaves, fascia, rafter tails, and window frames before swarm season rather than after.
- Screen attic, gable, and soffit vents with fine mesh to keep flying swarmers out of the roof structure.
- Sweep and note any pellet piles rather than just cleaning them, since a pile that returns means active feeding.
- Keep planting beds and decorative gravel below the stucco weep screed so soil dwellers cannot bypass it.
- Retune irrigation so nothing sprays the house, which matters in a city that averages only 15 inches of rain a year.
- Keep patio covers, trellises, and wooden fences that touch the house painted and off the ground.
- Clear the attic and garage perimeter enough that an inspector can actually see the framing.

Questions people ask
Do I have to tent my house for drywood termites?
Ask each company to explain what their method covers and what it does not. A single infested door frame or a short section of fascia found early can be a candidate for heat or localized injection instead. Companies recommend it when evidence appears in several places or in framing that cannot be accessed. Not always, but tenting is the only method that reaches colonies nobody located.
How long do I have to leave the house for fumigation?
In a dense Los Angeles neighborhood you should also expect coordination with neighbors about parking and yard access during setup. You will need to remove or bag food, medicine, and some other items, arrange for pets and plants, and provide access. Plan on two to three days away, including the fumigation itself and the clearance period before the structure is released.
Will a soil treatment stop drywood termites?
Confirm the species on paper before agreeing to any method. The reverse is also true: fumigating a structure does nothing to a subterranean colony living in the yard, which will simply forage back in. Drywood termites fly directly into wood and complete their life cycle inside it without contacting soil, so a treated soil zone never encounters them. No.
Is heat treatment as effective as fumigation?
Ask any company proposing heat how they monitor temperature and which parts of the building are included. Fumigant gas penetrates throughout a sealed structure. Heat leaves no chemical residue and usually lets you return the same day, but it succeeds only where the wood core actually reaches lethal temperature, so even heating and monitoring matter. They work differently and have different coverage profiles.
How long will treatment keep working?
Drywood treatments are not barriers, so future protection depends on sealing wood and reinspection. Bait systems run four to seven years or longer while serviced. For soil treatments, the University of Kentucky notes liquid termiticides must give at least five years of control applied to label directions, and University of Florida describes a range of two to fifteen or more years depending on product and soil.
Who arranges treatment in a Los Angeles condo or duplex?
Read the governing documents to see where common structure ends and unit interior begins, since that line determines who pays for what. Tenting covers an entire structure, so neighbors have to agree and schedule together. Usually the association or the owner, not the resident, because drywood colonies live in shared framing and roof structure that no single unit controls.
What should I ask before signing a treatment contract?
A company comfortable putting its scope on paper is the one worth hiring. Get answers written into the proposal. Ask five things: which species was identified and on what evidence, exactly what area the price covers, which California license branch applies to the work, how many reinspections are included, and what happens if activity returns during the coverage period.
Does treatment include repairing the damaged wood?
Get the repair scope quoted as its own line item. In California, structural repairs and corrections related to wood destroying organisms fall under a specific license branch, so some companies do handle both. Killing the colony does not restore a hollowed rafter tail or a compromised door frame, and the repair is carpentry work priced separately. Usually not by default, so ask.
