Termite Inspection in Los Angeles: How to Know If Your Home Has a Problem

Author : Alexia Gem | Published On : 15 Aug 2026

If you've ever found a small pile of what looks like sawdust near a windowsill, or noticed a hollow sound when you tap a porch step, you've probably wondered the same thing most Los Angeles homeowners eventually ask: is this termites, or am I overthinking it? It's a fair question, and one worth taking seriously. Termites don't announce themselves. They work quietly, inside walls and under floors, and by the time the damage is obvious, it's often already extensive.

This guide walks through the signs worth watching for, what actually happens during a professional termite inspection, and how to think about timing so you're catching problems early instead of reacting to them late.

The Signs Homeowners Usually Notice First

Termite activity tends to show up in a few recognizable ways, even if you're not looking for it.

Frass is usually the first clue. These are small, wood-colored pellets that drywood termites push out of tiny holes in infested wood. If you find what looks like coarse sand or sawdust near a windowsill, baseboard, or piece of furniture, that's frass, and it means there's an active colony nearby, not just old damage.

Mud tubes are the subterranean termite version of a warning sign. These are pencil-thin tunnels made of dirt and saliva that run along foundation walls, from the soil up to the wood they're feeding on. Termites build these tubes to stay protected from light and dry air while they travel, so finding one on your foundation is a clear signal that a colony is active somewhere close by.

Discarded wings show up seasonally, usually in late summer or early fall in Southern California, when termite colonies send out swarmers to start new colonies elsewhere. If you find small, uniform wings scattered near a window, door, or light fixture, it means a swarm has already happened, and there may be an established colony somewhere on or near your property.

Hollow-sounding wood is something you can check yourself. Tap along exposed wood trim, framing, or a deck board with the handle of a screwdriver. Wood that sounds hollow or papery instead of solid has likely been hollowed out from the inside, which is exactly how drywood and subterranean termites feed.

Blistered or sunken paint, especially on wood trim, can indicate moisture buildup or termite activity just beneath the surface. It's easy to mistake for ordinary weathering, which is part of why so many termite problems go unnoticed until they've spread.

What Homeowners Often Get Wrong

A few common assumptions tend to delay people from getting an inspection, and they're worth addressing directly.

Some homeowners assume that because they haven't seen termites themselves, there's nothing to worry about. In reality, both drywood and subterranean termites operate almost entirely out of sight. A colony can be active inside a wall for a year or more before anything becomes visible from the outside.

Others assume termite damage is covered by homeowners insurance, which it almost never is. Insurance treats termite damage as a maintenance issue, not a covered peril, since regular inspections are considered a homeowner's responsibility. That makes early detection the only real financial protection available, not a claim after the fact.

There's also a common belief that termites are a rural or older-home problem. In Los Angeles, that's simply not accurate. The mild, consistent climate here means termite colonies stay active year-round, in homes of every age and in nearly every neighborhood across the county.

What a Professional Termite Inspection Actually Covers

A proper inspection is more thorough than most people expect. A licensed inspector examines the exterior first: foundation walls, eaves, fascia boards, siding, decks, patios, and any point where wood contacts soil directly, since that's where subterranean termites most often gain entry.

Inside the home, inspectors check window and door frames, baseboards, cabinets, closets, and the garage. In a full inspection, they'll also access the attic and crawl space, two areas that are easy for homeowners to overlook but where termites frequently do the most damage without being noticed.

A more comprehensive inspection goes further, checking for the conditions that invite termites in the first place: water leaks, poor drainage, wood rot, and excess moisture. These conditions don't guarantee an infestation, but they significantly raise the risk, and addressing them proactively is often cheaper than dealing with an infestation later.

After the walkthrough, you should receive a written report, not just a verbal summary. A good report documents exactly what was found, where, the extent of any damage or activity, and clear next steps if treatment is needed. If the inspection is tied to a real estate transaction, the report also needs to meet WDO (Wood Destroying Organism) formatting requirements for lenders and escrow companies, which is a more formal process than a routine homeowner check.

How Often Should You Actually Get One?

Most experts recommend an annual termite inspection, regardless of whether you've noticed any warning signs. This isn't overly cautious advice. Termite colonies are slow-building and patient by nature, and annual inspections are what catch that activity while it's still small and inexpensive to address, rather than after it's spread through multiple areas of a structure.

If you're buying or selling a home, an inspection becomes even more time-sensitive, since it directly affects escrow timelines, lender requirements, and negotiation leverage between buyer and seller.

Why Los Angeles Homes Carry Extra Risk

Termites don't slow down here the way they do in colder parts of the country. There's no winter freeze to interrupt a colony's feeding cycle, which means the window for damage to accumulate never really closes. A home in Los Angeles that goes two or three years without an inspection is carrying meaningfully more risk than the same home would in a region with a real winter season.

Older housing stock across neighborhoods like Eagle Rock, Highland Park, and Silver Lake adds another layer of risk, since much of that construction predates modern termite-resistant building standards. Newer construction isn't automatically safe either, since untreated framing exposed during a remodel is just as vulnerable as an original 1920s beam.

When to Actually Call Someone

If you've noticed any of the signs described above, don't wait for them to get worse. If it's been over a year since your last inspection, that alone is reason enough to schedule one. And if you're in the middle of buying, selling, or refinancing a property, an inspection isn't optional in any practical sense, since it will come up one way or another during the transaction.

A home termite inspection in Los Angeles is a small, manageable step that consistently prevents a much larger, more expensive problem down the road. Catching activity early is almost always faster, cheaper, and less disruptive than waiting until the damage forces the issue.
