Termites rarely give much warning. By the time a homeowner in Walnut notices hollow-sounding wood, a scattering of small pellets near a baseboard, or a cluster of wings by a window, the colony has usually been working for some time. We inspect first, confirm what is there, and explain the treatment options before anything is scheduled.
Call (626) 532-8789 to get an inspection on the calendar, and we will handle the rest.
Walnut is a city of single-family homes, and the housing stock here is exactly the kind of construction that rewards a careful termite inspection. Wood-frame structures, attached garages, covered porches, and older additions are all places where termites establish themselves quietly. Whether you have noticed something specific or simply want to know the condition of the structure, the inspection is where every job starts.
Timing is the thing that drives most calls. A buyer or seller needs a WDO inspection before a closing date. A homeowner has spotted swarmers and wants answers before the weekend. A landlord has a tenant asking questions. The inspection can be arranged quickly, and the details are settled on the call: what the property involves, what you have noticed, and when a visit can happen.
In California, the inspection that comes up during a home sale or refinance is called a WDO inspection, which stands for wood-destroying organism inspection. It covers active termites, evidence of past activity, other wood-destroying organisms, and conditions that raise the risk of infestation. Sellers arrange them before listing. Buyers request them before closing. If you are in that situation, ask about a WDO inspection when you call and we will explain what it covers and confirm the rate.
We work around households, tenants, and businesses. If the property is occupied, we ask the right questions beforehand so the visit does not disrupt more than it needs to. The scope and the timing are both confirmed before anything is booked.
Protecting a structure starts with knowing what you are dealing with. The inspection covers the foundation perimeter, accessible framing, crawlspace and subfloor where present, sill plates, and attic space where entry allows. We look for active termites, mud tubes, frass, swarm evidence, and the conditions that make a structure more attractive to a colony.
In this part of California, drywood termites and desert subterranean termites are both active. They behave differently and require different responses. Drywood termites live inside the wood itself, with no soil contact needed. Subterranean termites come up from the ground and build the mud tubes that are often the first visible sign. The inspection identifies which type is present before any treatment is recommended.
The inspection may also note other wood-destroying insects, such as carpenter ants or wood-boring beetles, where they are found. Those are recorded as part of the inspection findings. They are not standalone services, but knowing they are present gives a complete picture of the structure's condition.
When a drywood infestation has spread through multiple areas of a structure and localized treatment cannot reach every gallery, whole-structure fumigation is the appropriate response. The building is tented and treated so the entire structure is covered at once. This is not the first step for every situation. It is the right call when the infestation is widespread, and the inspection findings tell us whether that is what the property needs.
Products are applied according to the label. Before the visit, we explain what preparation is required, what re-entry timing looks like, and what the household should do beforehand. Any questions about a specific product can be answered on the call.
For subterranean termites coming up from the soil, a liquid termiticide barrier is the standard approach. The soil around and under the foundation is trenched and treated with a non-repellent termiticide. Termites moving through the treated zone carry the product back to the colony over time. It is a direct method for addressing termites that are working their way up from the ground, and it is well suited to the slab foundations and crawlspace construction common in this area.
Where the infestation is smaller and the affected wood is accessible, a localized spot treatment or borate wood treatment addresses the problem without the scope of a full fumigation. Borate products penetrate the wood and protect it in the treated area. The inspection findings determine whether this is the right fit or whether a more comprehensive approach is needed.
Some jobs come from a specific part of the property rather than a whole-structure concern. Others come from a business rather than a homeowner. A few examples of what we take on:
Bait and monitoring stations are placed in the ground at intervals around the property perimeter. Foraging termites find the stations, feed, and carry the active ingredient back through the colony. Colony elimination happens gradually rather than all at once, and the stations remain in place between inspections as an ongoing early-warning system.
The difference between a bait system and a liquid barrier comes down to how each works. A liquid barrier treats the soil so termites moving through it are affected. A bait system draws termites to a specific point and uses their own foraging behavior to reach the colony. In some situations, one approach is the right fit on its own. In others, both are used together for broader coverage. The inspection findings and the property's construction are what determine the combination.
Checking the stations at each annual visit tells us whether new activity is present, whether the stations need attention, and whether the surrounding conditions have changed. That information shapes what happens next, and it is why ongoing monitoring is worth more than a single treatment and no follow-up.
The price is confirmed before anything is scheduled. When you call, we scope the job on the phone, ask about the property and what you have noticed, and give you the rate before a visit is booked. You are not committed to anything until you have heard the full picture.
What moves a quote is straightforward. The size of the structure matters. So does the construction type: a crawlspace property involves different access than a slab foundation. The extent of the infestation, the termite type, and the treatment the inspection calls for all factor in. A contained spot treatment and a whole-structure fumigation are priced differently, and we explain why.
The inspection findings and treatment cost are explained together so the recommendation is grounded in what was actually found. No upsells. No scare tactics. Just the treatment your home needs.
Moisture near the foundation draws termites, so drainage matters. A foundation that collects water, a crawlspace with poor ventilation, or timber framing that sits close to damp soil creates exactly the conditions a colony looks for. Fixing a drainage problem or correcting a ground-contact timber issue does not eliminate a termite problem that already exists, but it reduces the conditions that made the structure attractive in the first place.
The inspection notes conducive conditions alongside any active infestation. That includes standing moisture, wood debris stored against the foundation, poor subfloor airflow, and any place where wood contacts or comes close to the ground. Knowing what those conditions are is the first step toward changing them.
We treat your home the way we would treat our own, and that means the inspection report covers what is there and what is making it worse, not just what the treatment will address. Most of what comes up before a visit is answered on the list of termite services we handle.
We serve Walnut and the surrounding communities throughout Los Angeles County. That includes South San Jose Hills, Diamond Bar, West Covina, Covina, and Valinda. If your property is in this part of the county and you are not certain whether we cover your address, a quick call will confirm it.
The inspection covers the same areas regardless of size: foundation perimeter, accessible framing, crawlspace and subfloor where present, sill plates, and attic space where entry allows. An older property may have more areas of concern, more accumulated wood debris near the foundation, or construction details that give termites easier access. A larger property simply means more ground to cover. Neither changes the approach, but both can affect how long the inspection takes and what the findings include.
Yes. After the inspection, the technician explains what was found, where the activity or evidence is located, and what the treatment options are. The inspection findings and treatment cost are explained together so you understand what you are looking at before deciding how to proceed. You are not handed a report without context.
Drywood termites are a common concern in this part of California, particularly in older wood-frame construction where exposed framing, attic spaces, and eaves give a colony easy access. Desert subterranean termites are also active in the region and tend to show up where soil contacts or comes close to the structure. The inspection identifies which type is present, because the treatment that follows depends on that answer.
The property owner or an authorized representative can arrange the inspection. A tenant does not need to be present as long as access is arranged in advance. If the tenant will be home, coordinating the visit time with them ahead of the appointment avoids complications. We confirm the access arrangements when the inspection is booked.
For a liquid barrier applied to the exterior soil, food and medicines inside the home are generally not affected. Whole-structure fumigation requires specific preparation of food, medicines, and certain other items per the label directions, and the technician explains exactly what needs to be done before the job is scheduled. Nothing is left to figure out at the last minute.
Timing on a real estate inspection depends on the schedule at the time you call, and we confirm what is available when you reach us. Call as early in the transaction as the situation allows, because a WDO inspection that turns up activity may lead to a follow-up conversation between buyer, seller, and agent that takes its own time. We explain the scope and confirm the rate on the call so nothing is left to sort out the day before the closing date.
Termite damage does not hold still while a decision is being made. A colony that has been working through framing for one season is a more expensive repair than one caught early. The call is the point that changes it.
Call (626) 532-8789 any day from 9:00 AM to 8:00 PM.
We will scope the inspection on the phone, confirm the rate, and get it on the calendar. We cover Walnut and the surrounding area, and the first step is a conversation that costs nothing but a few minutes.
Other towns where we treat structures: Diamond Bar, Covina, Rowland Heights, Pomona, Glendora.
The rest are on our full list of areas.
Not every termite problem calls for the same fix, and the wrong treatment wastes time and money. We start with a thorough inspection that confirms the termite type and maps how far the activity has spread before a single treatment option is discussed. The table below lays out each method we use, what it is built for, and what you can expect from start to finish. Match the treatment to the termite, and the work addresses the actual problem rather than guessing at it.
| Treatment Option | How It Works | Best Suited For | What You Can Expect |
|---|---|---|---|
| Liquid Termiticide Barrier |
| Subterranean termites entering from the soil through the foundation perimeter or crawlspace | Single primary application with the treated zone remaining active in the soil. Annual inspection confirms the barrier is holding. Follow-up visits are scheduled if new activity is detected. |
| Termite Inspection |
| Any homeowner with a suspected termite problem, and buyers, sellers, agents, or lenders who need a WDO inspection ahead of a real estate transaction or refinance | Single visit that produces a clear picture of what is present and what is not. Findings are explained before any treatment is quoted. Home sale inspections are booked on a schedule that works around closing dates. |
| Whole-Structure Fumigation |
| Drywood termites that have spread through multiple areas of the structure where spot treatment cannot reach every gallery | Preparation instructions provided before the visit. Re-entry timing set by the label and confirmed in advance. Single treatment event that covers the entire structure at once. Annual inspection recommended afterward to catch any new activity. |
Call (626) 532-8789 to schedule a termite inspection or ask about a treatment quote. We are available every day from 9:00 AM to 8:00 PM.
