Hacienda Heights is a city of established residential neighborhoods, with a mix of older ranch-style homes, mid-century construction, and properties that have been added onto over the decades. That kind of housing stock tends to have crawlspaces, wood-frame additions, and subfloor framing that has not been looked at closely in years. When termite activity shows up in a structure like that, it is often further along than the first visible sign suggests. We inspect the structure from the foundation up, confirm what species is active and how far it has spread, and put together a treatment plan that fits the building. Sellers, landlords, and buyers in Hacienda Heights call for the same reason: they want a clear answer before the problem or the closing date gets ahead of them.
The work here runs the full range. Drywood termites are active throughout the region and can infest framing, eaves, and window casings without any contact with the soil. Subterranean termites come up from the ground and leave mud tubes along foundation walls and crawlspace piers. Both types call for different approaches, and both are present in this part of Los Angeles County. Realtors and homeowners get the same straight answer about what was found.

When subterranean termites are confirmed, the treatment targets the soil they travel through. A liquid termiticide barrier is applied to the soil around and beneath the foundation, creating a treated zone that foraging termites pass through and carry back to the colony. For this treatment to be done properly, the foundation perimeter needs to be reachable. That means clear access along the exterior walls, and in crawlspace properties, enough clearance to treat the soil beneath the subfloor framing as well.
The size of the structure and how it sits on the ground both shape what the job involves. A slab foundation is approached differently from a raised foundation with a crawlspace. Attached structures, porches, and additions that have been built over the years can create areas where access is limited or where the soil treatment needs to be applied through drilled access points rather than a trench. We go over all of that during the inspection so the treatment plan covers the full perimeter, not just the easy sections.
In-ground bait stations are another option for subterranean termite activity, and they are often installed alongside a liquid barrier. Stations are placed at intervals around the property. Termites find them during normal foraging, feed on the bait, and carry it back to the colony. The stations are checked on a regular schedule and also serve as an early-warning system between visits, flagging new activity before it has a chance to spread. For a property with ongoing termite pressure, that kind of monitoring adds a layer of protection that a one-time treatment alone does not provide.
A commercial property or a building with multiple units brings considerations that a single-family home does not. Tenants may need to be notified before a treatment begins. Access to individual units has to be coordinated. Treatments may need to be scheduled around business hours or around the occupancy schedule of the building. We work through those details before the job starts, not on the day of the treatment.
Larger structures also take longer to inspect thoroughly. A multi-unit building with a shared crawlspace or a commercial property with a slab and a wood-frame interior may have active termite damage in areas that are not immediately visible. The inspection covers the accessible areas of the structure and identifies where further investigation is warranted before any treatment is quoted. Property managers who handle multiple buildings in and around Hacienda Heights can call the same number as a homeowner. The process is the same: inspect first, then recommend.
A structure that was treated before and is showing activity again is not unusual. Non-repellent termiticide products work because termites cannot detect them and carry them back to the colony. If a previous treatment used a repellent product, or if the application did not cover the full perimeter, gaps in coverage can allow reinfestation. We inspect the structure, look at what was done before where that information is available, and treat what is actually there rather than repeating an approach that did not work.
A crawlspace is where subterranean termite activity often goes unnoticed the longest. The framing is out of sight, moisture levels can be higher than in the living space above, and wood-to-soil contact is more common in older construction. An inspection of the crawlspace covers the sill plates, floor joists, and any piers or posts, looking for mud tubes, damaged wood, and conditions that make the space more attractive to termites. When treatment is needed, it addresses the soil beneath the framing and any wood that can be directly treated.
Older homes in Hacienda Heights often have original wood framing that has never been treated. That wood can be dense and durable, but it is not immune. An older structure may also have framing configurations that make access more difficult, or wood that has already been compromised by moisture or previous pest activity. The inspection takes the age and construction of the building into account. Treatment recommendations for an older structure are based on what the inspection actually finds, not on a standard package.
A buyer who wants to know what they are purchasing before the sale closes needs a thorough inspection, not a quick look. The WDO inspection, which stands for wood-destroying organism inspection, is what California uses for this purpose. It covers termites and other wood-destroying organisms that could affect the property. If the inspection finds active termites, damage, or conditions that warrant attention, that information is part of the picture a buyer needs before the transaction is complete. Scheduling the inspection early in the escrow period leaves time to act on what is found.
Frass near a baseboard or a windowsill, and swarmers inside the house, are both signs that drywood termites may be active in the structure. Frass looks like small pellets and collects below kick-out holes in the wood. Swarmers are reproductive termites, and finding them indoors points to a colony that is either established inside the structure or very close to it. When either of these appears, an inspection confirms the species, the location, and how far the activity has spread. That answer determines whether a localized spot treatment is the right call or whether the infestation has spread far enough to warrant whole-structure fumigation.
A good inspection isn't complicated, it's just thorough. When you call, we go over what you have noticed and what the property looks like, and we use that to scope the inspection before anything is scheduled. The inspection details, including what the visit covers and what it costs, are confirmed on the call.
If you are working toward a closing date, call early. A WDO inspection for a home sale in Hacienda Heights can be scheduled around the timeline, but a tight escrow period leaves less room to work with. We take short-notice requests and can tell you on the call what the schedule allows. Tenants and households can be worked around with some advance notice, and we explain any preparation that is needed before the visit. One call starts the inspection.
The cost of a termite treatment is not a single number that applies to every property. The size of the structure, the construction type, which treatment fits the termite species confirmed during the inspection, and how reachable the affected framing is all affect what the job involves and what it costs. A liquid barrier treatment on a large raised-foundation home is priced differently from a spot treatment on a smaller slab structure. A whole-structure fumigation for a widespread drywood infestation is a different scope entirely.
The price is confirmed after the inspection scopes the job. When you call, we explain what the inspection covers and what it costs, and you know both before anything is scheduled. Ask what a particular treatment involves and you get a straight answer. There are no numbers to commit to on this page because the right number depends on what the inspection finds. What each job covers is written out on our page of termite control services.

Older homes often have construction details that require closer attention during an inspection, including original wood framing that has never been treated, areas where wood contacts the soil, and additions that may have been built without the same foundation clearance as the original structure. These conditions do not change the inspection process itself, but they do affect where the inspector focuses and what the report is likely to note. The treatment recommendation that follows is based on what the inspection actually finds in that structure, not on a standard approach applied to every home of a similar age.
Some disturbance to the soil around the foundation is part of the process, since the treatment involves trenching along the perimeter. Established plantings close to the foundation may be affected during that work. The extent of any disturbance depends on the specific layout of the property and is something we can walk through when the inspection is complete and the treatment plan is confirmed.
Mud tubes are a reliable sign that subterranean termites are active, even when the wood inside the structure looks intact from the surface. Termites can be well into the framing before any interior damage is visible. The right step is to call and schedule an inspection, which will confirm whether the colony is actively feeding on the structure and how far the activity has reached. Catching it at the mud-tube stage generally keeps the treatment scope smaller than waiting for damage to appear.
If you have seen swarmers, found frass, or noticed something in the crawlspace that does not look right, the next step is an inspection. We are available every day from 8:30 AM to 10:00 PM.

Not every termite problem calls for the same fix, and applying the wrong treatment wastes time and money. We start with an inspection that identifies the species and maps how far the activity has spread, then match the treatment to what we actually find. The table below lays out each method we use, what it is built for, and what to expect when the work gets underway.
| Treatment Approach | How We Do It | Recommended For | Timeline and Results |
|---|---|---|---|
| Wood and Spot Treatment | Borate product applied directly to accessible wood, Localized treatment targets a contained infestation, No soil work required for this method | Contained drywood termite infestations in accessible wood where fumigation is not warranted | Typically completed in a single visit when the affected area is accessible. Best suited to situations where the inspection confirms the infestation is limited in scope. |
| Liquid Termiticide Barrier | Soil trenched around the foundation, Non-repellent termiticide applied to treated zone, Subterranean termites carry product back to colony | Subterranean termites entering from the soil through the foundation perimeter or crawlspace | Completed in a single visit for most structures. The treated zone remains in the soil around the foundation. Annual inspection recommended to confirm the zone is holding and no new activity has appeared. |
| Annual Inspection and Monitoring | Full structure re-inspected each year, Bait stations checked and refreshed where in place, New activity identified before it spreads | Any property that has been treated and any homeowner who wants ongoing early detection rather than waiting for visible damage | Recurring annual visit. Not a warranty or a bond. A straightforward plan for keeping the structure checked year after year so new activity is caught early. |
