Angelus Termite Control has been protecting homes and businesses in El Monte since 1925. For over a century, we have been the local termite specialist serving the San Gabriel Valley, and we know what termite pressure looks like in this part of Los Angeles County. If you have spotted mud tubes along your foundation, seen swarmers inside your home, or noticed wood that sounds hollow when you knock on it, the path forward is straightforward. We inspect the structure, identify the termite type, treat with the method that fits, and put a protection plan in place so the problem does not come back. Trusted by local homeowners, realtors, and businesses across the valley, we are here when you need us.
One number. One inspector. One protected structure.
We inspect for termites every day, and we know where they hide. Catching the problem early makes a real difference in how much damage a colony can do before treatment begins.
Common warning signs include:
Subterranean termites typically announce themselves through mud tubes and swarmers that emerge from the soil. Drywood termites live entirely inside the wood and often go undetected until frass appears or the damage becomes structural. Because the signs differ and the treatments differ, an inspection is the necessary first step before any work is quoted.
One call starts the inspection.
Every job begins with a thorough inspection. Our inspector examines the structure from the foundation to the rafters, identifies which termite species is present, and maps how far the infestation has spread. No treatment is quoted until that inspection is complete and the findings are clear.
Inspectors who show up on time and ready to work means you are not waiting around for a vague estimate. We walk the property with you, explain what we find, and give you transparent pricing with no surprises attached.
Same-day and fast-turnaround inspections are available for urgent situations. Whether you have just spotted active swarmers or you are under a deadline to close on a property, we can get an inspector out quickly.
We'll be there for the inspection.
A wood-destroying organism (WDO) inspection, sometimes called a WDI inspection or termite inspection, is required by many lenders and escrow officers for home purchases, sales, and refinancing in California. The report documents all wood-destroying organisms found in the structure. Within that inspection context, the report may also note the presence of carpenter ants, wood-boring or powderpost beetles, and wood-decay fungus, because lenders and escrow require a complete picture of the structure's condition.
The completed report produces a termite clearance letter that satisfies lender requirements and keeps the transaction moving. Real estate agents and escrow officers across the San Gabriel Valley rely on us to deliver accurate reports on a schedule that respects closing deadlines.
Fast WDO reports. Honest findings. Closings kept on schedule.
Treating termites takes the right termiticide for the right species. In El Monte and across the San Gabriel Valley, both drywood and subterranean termites are active concerns. An inspection identifies which type is present, and the treatment follows directly from that finding.
Drywood termites live inside the wood and do not need soil contact. A widespread drywood infestation typically calls for whole-structure fumigation, which is the only way to reach every gallery and void throughout the building at once. Subterranean and Formosan termites travel through the soil, and they are handled with liquid barrier treatments and in-ground bait systems. Experienced termite technicians who respect your home will match the method to what the inspection reveals, not to what is easiest to sell.
Here is an overview of the treatment options we use.
We trench and treat the soil around and under the foundation with a non-repellent termiticide, creating a continuous treated zone. Subterranean and Formosan termites foraging through the soil contact the treatment and carry it back to the colony, eliminating it from the inside out. This approach covers the foundation perimeter, slab edges, and crawlspace and subfloor areas where soil-to-wood contact creates the highest risk.
Non-repellent termiticides are undetectable to termites, which is what makes them effective. The colony does not avoid the treated zone; it moves through it.
In-ground bait stations are placed around the property perimeter at intervals that give termites reliable access. Foraging workers find the bait, recruit nestmates to the food source, and carry the active ingredient back through the colony. Over time, the colony is eliminated. The stations remain in place after treatment as an ongoing monitoring network, giving us early warning if new termite activity develops. Bait systems are often paired with a liquid barrier for comprehensive, layered coverage.
When a drywood termite infestation has spread through multiple areas of a structure, fumigation is the recommended solution. The building is sealed and the fumigant penetrates every wall cavity, void, and piece of wood in the structure at once. There is no localized treatment that can match that reach when the infestation is widespread.
We walk you through the process, the preparation steps, and the timeline before any work begins. Pricing is transparent and scheduling is handled with your situation in mind.
For smaller, contained infestations where the affected wood is accessible, localized and spot treatments are an effective option. Borate wood treatment applied to accessible structural lumber kills active termites and provides ongoing protection against reinfestation. Borate treatments also protect treated wood against wood-decay fungus and wood-boring beetles in areas where those conditions exist. When the scope of the infestation is limited and the wood is reachable, spot treatment avoids the disruption of a full fumigation.
For builders, contractors, and property developers, treating the soil before a slab is poured creates a termiticide barrier that protects the structure from the ground up. In a high-activity region like Los Angeles County, pre-construction treatment is a practical investment. We work with construction schedules and coordinate treatment timing so it fits the project.
Before the colony does another season of damage, a service agreement locks in your coverage and keeps the structure protected year after year. After treatment is complete, an annual inspection confirms the structure remains termite-free. If termites return within the coverage period, we retreat at no additional charge.
The warranty is renewable, which means coverage does not lapse as long as you keep the agreement current. It is also transferable, which adds value if you sell the property. Buyers and their lenders look favorably on a home that comes with documented treatment history and an active service agreement.
For any homeowner in a region where termite pressure is a year-round reality, an annual inspection and renewable warranty is the smart long-term move.
Let us take care of the colony.
Whether it's one mud tube or a colony under the whole slab, we approach every job the same way: inspect thoroughly, explain clearly, and treat with the right method for what we find. Our reputation is local, so every inspection matters to us.
We serve El Monte and the surrounding communities throughout the San Gabriel Valley and eastern Los Angeles County, including Baldwin Park, West Covina, Azusa, Arcadia, Rosemead, Temple City, Monrovia, and Duarte. Transparent pricing with no hidden fees means you know what the job costs before any work begins.
If you are a homeowner, landlord, property manager, real estate agent, or business owner, we are the local termite company that shows up prepared and gives you a straight answer.
The dry climate in the Los Angeles basin does not reduce termite pressure the way many homeowners expect. Drywood termites thrive in exactly this kind of warm, low-humidity environment, and subterranean species are active throughout the region wherever soil and wood come into contact. El Monte properties face genuine, year-round termite pressure, and an inspection is the only way to know whether your structure is currently affected.
Call us at (626) 532-8789 and we will get you on the schedule. We offer same-day and next-day availability for most locations in El Monte and the surrounding San Gabriel Valley. The call takes a few minutes, and we will confirm the appointment time before we hang up.
Swarmers indoors are a strong indicator that a colony is already established somewhere in or near the structure. They do not fly in from outside looking for a place to start. An inspection after a swarm event is the right next step because the colony that produced them is likely already at work.
A wood-destroying organism (WDO) inspection is the report lenders and escrow officers require for most home purchases, sales, and refinancing transactions in California. It documents active termites, prior termite damage, and other wood-destroying organisms found in the structure. If you have a closing deadline, call us early so the report does not hold up your transaction.
Same-day and next-day inspections are available in most cases for El Monte and the surrounding communities. We work around your schedule, and urgent situations, including active swarms or real estate deadlines, get priority attention. Call (626) 532-8789 and we will find the earliest opening.
The quote comes after the inspection, not before. We inspect the structure, identify the termite species and the extent of the infestation, and then walk you through the findings and the recommended treatment before any number is put in front of you. That way the quote reflects what the job actually requires.
Yes. After the inspection we give you a clear quote based on what we found. That is the number you plan around. There are no surprise line items added after the work begins, and pricing is transparent with no hidden fees.
Subterranean termites enter through the soil, moving up through cracks in the slab, foundation gaps, or any point where wood contacts the ground. Drywood termites enter through exposed wood surfaces, cracks in trim, or gaps around windows and doors, often during a swarm. Both types can be active for a long time before the signs become visible.
Not the loudest termite ad in town, just the most thorough inspection.
Angelus Termite Control has been doing this work in El Monte and across the San Gabriel Valley since 1925. That kind of track record is built one inspection at a time, and we take every one seriously. Work is performed by experienced termite technicians who respect your home and treat the property the way they would want their own treated.
Same-day and emergency scheduling is available when the situation calls for it. Pricing is transparent and quoted after the inspection, so you know exactly what you are paying for and why. The process is simple: call, schedule the inspection, and get a clear quote before any work begins.

Every termite problem starts with an inspection, because the species present determines the treatment. Subterranean and Formosan termites travel through the soil and call for a barrier or bait approach, while drywood termites live inside the wood and a widespread infestation requires fumigation to reach every gallery at once. We identify what is active in your structure before we quote anything, and we match the method to what we find. The table below walks through each option so you know what to expect before we arrive.

How do I tell whether I have subterranean or drywood termites?
The signs are different enough that a close look usually points in the right direction. Subterranean termites build mud tubes, the pencil-width tunnels of soil and debris you see running along foundation walls, crawlspace supports, or exterior concrete. They need moisture and soil contact to survive. Drywood termites live entirely inside the wood and leave frass behind, small pellet-like droppings pushed out of tiny kick-out holes in the wood surface. Swarmers from both types may appear indoors, but the mud tube or frass tells us which one we are dealing with. An inspection confirms it and determines how far the activity has spread.
What do mud tubes on my foundation actually mean?
Mud tubes are the travel corridors subterranean termites build to move between the soil and the wood in your structure while staying protected from open air. Finding one or more on your foundation wall, slab edge, or crawlspace supports is a strong indicator that a subterranean colony is actively foraging into the structure. The tube itself does not tell you how large the colony is or how far the damage has progressed. That is what the inspection is for. We locate the tubes, trace where they lead, and map the extent of the infestation before any treatment is quoted.
Right Treatment Matched to the Termite Species
We inspect before we quote, and the treatment recommendation follows directly from what the inspection reveals. You will never be sold a method that does not fit the species or the scope of the infestation.
I saw swarmers inside my home this spring. What does that mean?
Swarmers are the reproductive members of a mature termite colony, and finding them indoors means a colony is already established somewhere in or near the structure. They do not fly in from outside looking for a place to start. Seeing them inside, especially near windows or lights, is a sign the colony has been present long enough to produce a reproductive flight. The discarded wings left on windowsills or floors are often the first thing homeowners notice. An inspection after a swarm event is the right next step so we can locate the colony and assess the damage before another season passes.
Do I need a liquid barrier, bait stations, or fumigation?
The answer depends on what species is active and how far the infestation has spread. Liquid barriers and bait systems are the primary tools for subterranean and Formosan termites that travel through the soil. Fumigation is the recommended approach when drywood termites have spread through multiple areas of the structure, because it is the only method that reaches every gallery and void at once. A localized spot treatment may be appropriate when a drywood infestation is small and the affected wood is accessible. We do not recommend a treatment until the inspection tells us which species is present and where the activity is concentrated.
How does a liquid termiticide barrier protect my foundation?
We trench the soil around the foundation perimeter and along slab edges, then apply a non-repellent termiticide to the trench and any sub-slab areas we can access. The treated zone becomes invisible to termites because non-repellent termiticides cannot be detected by foraging workers. Termites move through the treated soil, pick up the active ingredient, and carry it back to the colony through normal social contact. The colony is eliminated from the inside out over time. The treated zone remains active in the soil for years, and an annual inspection confirms it is still doing its job.
Fast Turnaround on Real Estate WDO Reports
Closing deadlines do not wait, and neither do we. Same-day and fast-turnaround inspections are available, and we deliver accurate WDO reports on a schedule that keeps your transaction on track.
Are termite treatments safe for children and pets?
We follow all label directions and application protocols, and we explain any preparation steps or re-entry intervals before work begins. For most liquid barrier and bait treatments, the preparation required is straightforward and the treated areas are the soil around the exterior of the foundation. Whole-structure fumigation requires occupants, including pets, to vacate the structure for the treatment period and until the structure has been cleared and ventilated. We walk you through exactly what is required for your specific treatment before scheduling begins so there are no surprises.
Is a WDO inspection required when buying or selling a home in California?
Most lenders and escrow officers require a wood-destroying organism inspection as a condition of financing for home purchases, sales, and refinancing in California. The report documents active termites, prior termite damage, and other wood-destroying organisms found in the structure, including carpenter ants, wood-boring or powderpost beetles, and wood-decay fungus. The completed report produces a clearance letter that satisfies the lender requirement. If you are working toward a closing deadline, calling us early in the transaction gives us time to schedule the inspection and deliver the report without putting the timeline at risk.
How quickly can you turn around a WDO report for a closing?
We understand that real estate transactions run on tight schedules, and we treat inspection requests with deadlines as a priority. Same-day and fast-turnaround inspections are available for most locations in El Monte and the surrounding San Gabriel Valley. When you call, let us know the closing date and we will schedule the inspection and deliver the report on a timeline that keeps the transaction moving.
Renewable Termite Warranty and Retreatment
After treatment is complete, a renewable service agreement keeps your structure covered year after year. If termites return during the coverage period, we retreat at no additional charge.
How often should a home be inspected for termites?
An annual inspection is the standard recommendation for homes in the San Gabriel Valley and greater Los Angeles County, where both drywood and subterranean termites are active year-round. Annual inspections catch new activity early, before a colony has time to do significant structural damage, and they are required to keep a renewable service agreement current. Homes with prior termite history, older construction, or conditions that favor termite activity, such as wood-to-soil contact or moisture issues, benefit most from consistent annual coverage.
Will termites come back after treatment, and what does the warranty cover?
Treatment eliminates the active colony and, in the case of a liquid barrier, creates a treated zone that deters new subterranean termite entry for years. That said, termite pressure in this region is year-round, and new colonies can establish over time. A renewable service agreement addresses that reality directly. Under an active agreement, we inspect annually and retreat at no additional charge if termites return within the coverage period. The warranty is also transferable, which means it stays with the property if you sell, adding documented protection history that buyers and lenders value.
