How to Tell If You Have a Termite Infestation: Early Signs Every Homeowner Must Know

Knowing how to tell if you have a termite infestation could be the difference between a minor treatment bill and a five-figure structural repair — and unfortunately, most homeowners only find out they have a problem after the damage is already done. Termites are often called “silent destroyers” for a good reason. They tunnel through the wood inside your walls, floors, and foundation beams without making a sound, without announcing themselves, and without leaving any obvious trace on the surface until the destruction is severe.

In Oklahoma, and especially here in Broken Arrow and the greater Tulsa area, subterranean termites are extraordinarily active. The warm, humid climate creates near-perfect conditions for colonies to thrive year-round. A single mature colony can contain hundreds of thousands — even millions — of individual workers, each one quietly chewing through the wooden structure of your home every single day.

The good news is that termites do leave behind clues. If you know exactly what to look for, you can catch an infestation in its early stages, before irreversible damage sets in. This guide walks you through every early warning sign in detail, so you can protect your most valuable investment before it is too late.

Quick fact: The National Pest Management Association estimates that termites cause over $5 billion in property damage across the United States every year — damage that is rarely covered by homeowner’s insurance.

Why Early Detection of a Termite Infestation Matters So Much

Termites do not cause noticeable damage overnight. A new colony starts small — a queen, a king, and a handful of workers establishing their nest underground or inside a piece of moist wood. In the first year or two, you may notice absolutely nothing wrong. But colonies grow exponentially. By the time you see sagging floors, hollow-sounding walls, or bubbled paint, the colony has likely been feeding for years. It has already compromised structural components that are expensive to replace.

Early detection is not just about saving money — though that is a very real benefit. It is also about protecting everyone living in your home. Termite-weakened floor joists, support beams, and wall studs can fail without warning. Annual inspections and knowing the early signs are the two most powerful tools you have on your side.

The 7 Early Warning Signs of a Termite Infestation

None of these signs alone is a definitive confirmation. But if you spot one — especially in combination with another — you should treat it as a serious red flag and contact a licensed pest professional immediately.

Sign 1: Mud tubes on your foundation or walls

Subterranean termites, the most destructive species found in Oklahoma, cannot survive exposure to open air. They build pencil-width tunnels made of soil, wood particles, and termite saliva to travel between their underground colonies and their food source — your home. These mud tubes most commonly appear along the base of exterior walls, on concrete block foundations, along piers in crawl spaces, and on the inside of garage walls. Run your finger along the base of your foundation every few months. If you find one of these narrow, muddy channels, there is almost certainly an active or recent infestation present.

Sign 2: Discarded wings near windowsills and doorways

Once a termite colony matures and reaches a certain size, it produces “swarmers” — winged reproductive termites whose job is to fly out, mate, and start new colonies. In Oklahoma, swarmer season typically runs from late February through May, peaking on warm days after rain. Swarmers are poor fliers and rarely travel far. They shed their wings almost immediately after landing. Finding a small pile of translucent, equal-length wings near a window, door frame, or light fixture is one of the clearest early indicators that a mature colony is either inside your home or very nearby.

Sign 3: Hollow-sounding or blistered wood

Termites eat wood from the inside out, leaving a paper-thin outer shell intact while hollowing out the structure beneath. Knock on your baseboards, door frames, windowsills, and wooden support structures. Wood that sounds hollow — almost like a drum — when tapped is a strong sign that termites have been at work inside. Similarly, wood that appears blistered or uneven on the surface, like water damage, can indicate feeding activity just beneath. The difference from actual water damage is that termite-affected wood often crumbles or gives way under slight pressure.

Sign 4: Frass — termite droppings

Drywood termites, which live and nest directly inside wood rather than in the soil, push their fecal pellets out of tiny holes in the wood to keep their tunnels clean. These droppings, known as frass, are tiny, sand-like, typically six-sided, and uniform in shape. They range in color from light beige to dark brown, depending on the wood the termites are feeding on. You will often find small piles of frass on window ledges, floors, or surfaces directly below infested wood. Many homeowners mistake them for sawdust or dirt, which is exactly why this sign is often missed.

Sign 5: Doors and windows that suddenly stick

As termites consume the wood in and around door and window frames, the frames warp and shift. This causes doors that previously opened smoothly to feel stiff or require force to open suddenly. Windows may stick or refuse to open cleanly. Homeowners almost always attribute this to humidity or seasonal shifting of the house — and while those causes are real, persistent sticking in multiple spots, especially combined with any of the other signs on this list, deserves a professional look. By the time termite feeding visibly warps the frames, the damage is already substantial.

Sign 6: Paint that bubbles or appears uneven

When termites feed close to the surface of a painted wall, they introduce moisture into the wood as they tunnel. This causes the paint above to bubble, peel, or appear uneven, mimicking water damage from a pipe leak. If you notice paint bubbling in an area with no obvious plumbing above it and the wall has not been exposed to flooding, termites should move to the top of your suspect list. Press lightly on the bubbled area — if the surface feels soft or gives slightly, that is a serious warning sign requiring immediate professional inspection.

Sign 7: Visible damage to structural wood in crawl spaces or attics

Crawl spaces and attics are the most frequently overlooked parts of any home, which is exactly why termites love them. Wood attacked by subterranean termites often has a layered, honeycomb-like appearance on the inside, with tunnels running parallel to the grain of the wood. Drywood termite damage tends to run across the grain, creating a series of galleries that appear hollow and smooth. If you can safely access your crawl space or attic, grab a flashlight and a screwdriver. Probe the wood beams with the screwdriver tip — if it sinks in with minimal resistance, you likely have an active or past infestation that needs immediate attention.

Important note: Finding termite damage does not necessarily mean an active infestation is still present. But it does mean your home has been vulnerable, and a professional needs to assess whether the colony has moved on, gone deeper, or is still actively feeding. Never assume old damage means the problem is solved.

The Difference Between Termite Damage and Water Damage

One of the most common mistakes homeowners make is dismissing what appears to be water damage without investigating whether termites are actually the cause. The two types of damage can look strikingly similar — blistered paint, soft or discolored wood, uneven surfaces — but the underlying causes and the appropriate responses are completely different.

The key distinction is location and pattern. Water damage is almost always traceable to a specific source: a leaking pipe above, a roof penetration, or an improperly sealed window. It follows gravity and tends to stain in a downward pattern. Termite damage, on the other hand, does not follow gravity. It appears wherever termites are feeding, and it is often accompanied by the other signs described above — mud tubes, wings, frass — that water alone cannot explain. When in doubt, call a professional. A licensed inspector can identify the cause definitively and tell you whether you have a plumbing problem, a pest problem, or both.

What Happens If You Ignore the Early Signs

The temptation to wait and see — to hope that strange-looking wood is just age, that the discarded wings blew in from outside, that the sticking door is just humidity — is understandable. Pest treatment costs money and time. But no investment you make in your home comes close to the financial and structural risk of an ignored termite infestation.

Termite colonies do not shrink or move on. They grow. A colony that starts with a few thousand workers grows to tens of thousands, then hundreds of thousands, over the span of three to five years. The damage compounds nonlinearly — the more wood they consume, the weaker the structure becomes, and weakened wood absorbs more moisture, which in turn attracts more termite activity. Homeowners who catch and treat an infestation in its first year typically spend a fraction of what those who wait spend on both treatment and repairs combined. The Oklahoma climate means you are not dealing with a seasonal threat — termites can feed 365 days a year here, and every day you wait is another day they are working against you.

Frequently Asked Questions

1. How quickly can termites damage a home?

A single termite colony of around 60,000 workers can consume roughly one foot of a 2×4 piece of wood in just five months. Larger colonies — some numbering in the millions — can cause structurally significant damage within a year or two if left unchecked. The danger is that most of this destruction happens silently inside walls, floors, and foundations, completely out of sight.

2. What is the difference between termites and flying ants?

Both insects swarm and can look similar at a glance, but there are clear differences. Termites have straight antennae, a broad waist with no pinch between the thorax and abdomen, and wings of equal length. Flying ants have elbowed antennae, a distinctly pinched waist, and wings of unequal length. If you are unsure, collect a sample in a sealed bag and have it identified by a professional before taking any action.

3. Can I treat a termite infestation myself?

DIY termite treatments — liquid repellents, cardboard traps, orange oil — can suppress surface activity but rarely eliminate the colony. Termites nest deep underground or inside structural wood, often in areas completely inaccessible to store-bought products. Professional treatment uses licensed termiticides applied at precise concentrations and in specific placement patterns to reach the queen and the entire colony, the only way to permanently stop the infestation.

4. How often should I have my home inspected for termites in Oklahoma?

Pest control professionals recommend an annual termite inspection for homes in Oklahoma. The warm, humid climate in Broken Arrow and the broader Tulsa metro area makes the region particularly active for subterranean termites, especially from February through May when swarm season peaks. Annual inspections catch new activity early, before repair costs escalate significantly.

5. Does homeowner’s insurance cover termite damage?

In most cases, standard homeowner’s insurance policies do not cover termite damage. Insurers typically classify termite infestations as preventable maintenance issues rather than sudden or accidental losses. This makes early detection and routine professional inspections even more critical — the cost of an annual inspection is a small fraction of what out-of-pocket structural repairs can run once damage becomes severe.
