You notice a small pile beneath a windowsill, wipe it away, and assume it is sawdust or tracked-in dirt. A few days later, the pile returns in the same place. That tiny mound may be termite poop, one of the most overlooked signs of drywood termites.
Termite poop is also called termite frass. It does not look like the waste most people expect from an insect. Drywood termite droppings are hard, dry pellets that collect below tiny openings in wood. You may find them near baseboards, door frames, attic beams, cabinets, furniture, or hardwood floors.
Finding frass does not reveal how large an infestation is, but it does show that termites have occupied nearby wood. Since termites can remain hidden inside walls and structural materials, even a small pile deserves a closer look.
What Does Termite Poop Look Like?
Termite poop looks like tiny grains of sand or neatly shaped pieces of sawdust. Individual pellets may be tan, brown, reddish, or nearly black. Their color often reflects the wood the termites have eaten, so a single pile can contain several shades.
The shape matters more than the color. Sawdust contains flakes, soft powder, and irregular wood fibers. Termite frass usually looks like a collection of hard, evenly sized grains.
| Feature | Termite Frass | Sawdust | Carpenter Ant Debris |
| Texture | Hard, dry pellets | Soft powder and fibers | Coarse wood fragments |
| Shape | Fairly uniform grains | Irregular flakes and dust | Mixed, uneven pieces |
| Common contents | Pellets only | Wood fibers | Wood, soil, and insect parts |
| Typical location | Below tiny holes in wood | Near drilling or damaged wood | Near nest openings |
| Best next step | Inspect the wood above | Check for recent work | Look for ants and larger openings |
A tiny opening above the pile makes drywood termites more likely. These openings are often called kick-out holes, and they can be so small that they look like pinpricks in painted trim.
Why Drywood Termites Leave Pellets Behind
Drywood termites live inside the wood they eat. Unlike subterranean termites, they do not need regular contact with soil. A colony may occupy a door frame, roof beam, cabinet, or piece of furniture while staying completely out of sight.
As termites tunnel and feed, waste builds up inside their galleries. Workers push the pellets through small openings to keep those spaces clear. The pellets fall and form a pile below the opening. This behavior creates one of the few visible clues of drywood termite activity. You may never see the termites themselves, even while the colony continues feeding inside the wood.
The place where the pellets land is not always the exact location of the damage. Frass can fall from an opening several feet above the floor, roll along trim, or collect in a corner. That is why an inspection should include the wood above and around the pile, not just the surface where the pellets settled.
Where Termite Droppings Appear in Your Home
Termite droppings can appear anywhere drywood termites have access to suitable wood. Windowsills are common discovery points because pellets fall onto a flat, visible surface. You may also find them near baseboards, door frames, cabinets, floor edges, or wooden furniture.
Attics provide plenty of protected wood and often go unchecked for long periods. Frass may collect below rafters, roof supports, stored furniture, or framing. A pile can remain unnoticed for months if you rarely enter the space.
Drywood termites can also infest movable objects. Antique furniture, picture frames, shelving, and stored lumber may carry termites into a home. A pellet pile beneath one object does not always mean the colony started in the building itself.
| Location | What to Check Nearby | Why It Matters |
| Windowsill | Trim, frame corners, and nearby walls | Pellets often fall onto flat ledges |
| Baseboard | Small holes, bubbling paint, and loose trim | Damage may sit behind the visible surface |
| Attic | Rafters, beams, and stored wood | Termites can remain hidden for long periods |
| Furniture | Joints, undersides, and back panels | Infested furniture can introduce termites |
| Cabinet | Shelves, seams, and wall contact points | Enclosed wood gives termites protected space |
| Hardwood floor | Gaps, soft spots, and nearby trim | Frass may fall from wood above or beside it |
Check the area above the droppings for pin-sized holes, cracked finishes, blistered paint, or wood that sounds hollow when tapped. These clues do not show the full extent of an infestation, but they can help identify the most likely source.
Does Termite Poop Mean the Infestation Is Active?
Finding termite poop confirms that drywood termites have occupied the wood. It does not always prove that they are active at the exact moment you discover the pile.
Old pellets may remain in corners, wall gaps, or furniture long after they were expelled. Cleaning, vibration, or moving an object can dislodge material that has been sitting inside a cavity.
A pile that returns after cleaning is more concerning. Fresh frass suggests that termites may still be clearing their galleries. Take a clear photo before removing it, then check the area again over the next several days.
You should not rely on that test alone. A colony may stop using one opening and begin using another. Termites can also remain active without producing a visible pile in a room you regularly use.
Frass means the wood deserves a professional inspection. It should not be treated as proof that the problem is gone simply because the pellets look old or stop appearing.
Termite Poop Versus Other Signs of Termites
Termite poop is closely linked with drywood termites, but Louisiana homes can also face Eastern subterranean termites and Formosan subterranean termites. These groups live differently and often leave different evidence.
Drywood termites live inside the wood and commonly leave hard pellets. Subterranean termites usually maintain contact with the soil and build mud tubes to travel between the ground and a structure. You may also notice discarded wings, swarmers, soft wood, or damage that resembles water staining.
| Sign | Most Often Linked With | What It May Look Like |
| Hard pellet piles | Drywood termites | Sand-like grains below wood |
| Small kick-out holes | Drywood termites | Pin-sized openings in trim or furniture |
| Mud tubes | Subterranean termites | Brown shelter tubes on walls or foundations |
| Discarded wings | Drywood or subterranean swarmers | Clear or pale wings near doors and windows |
| Hollow or damaged wood | Several termite types | Weak, blistered, or thin-sounding wood |
| Swarming insects | Reproductive termites | Winged termites near lights or windows |
This distinction matters because the absence of termite poop does not mean your home is free of termites. A subterranean colony can damage a structure without leaving a single pile of frass.
LaJaunie’s internal service guidance also identifies drywood pellets, mud tubes, discarded wings, splintering beams, and honeycomb-like wood damage as signs that deserve attention.
Why This Warning Sign Matters in Louisiana
Louisiana’s warm, humid climate supports long periods of termite activity. Moisture around foundations, leaking plumbing, clogged gutters, damaged wood, and tree stumps near a house can create favorable conditions for subterranean termites.
Drywood termites do not depend on soil moisture in the same way. They can live inside sound, dry wood, which is why a clean and well-maintained room can still develop a small pile of frass.
Formosan termites add another concern for South Louisiana homeowners. The LSU AgCenter reports that mature Formosan termite colonies can contain several million termites. Their large colonies and broad foraging range can make infestations harder to detect from one visible sign.
This does not mean every pile of pellets points to severe structural damage. It does mean that Louisiana homeowners should take termite evidence seriously and avoid waiting for obvious damage to appear.
The Cost of Overlooking Early Termite Evidence
A pile of frass may look minor, but the insects producing it are feeding inside wood. Damage can remain hidden beneath paint, behind drywall, or inside framing until repairs become more involved.
The U.S. Environmental Protection Agency reports that termites cause billions of dollars in structural damage each year. Property owners also spend more than $2 billion annually on termite treatment. Those numbers cover many types of buildings and termite species. They do not mean every pellet pile points to a major repair. They do show why termite evidence should be checked before months or years pass.
Drywood termite damage often follows the grain of the wood. The outer surface may appear normal while galleries expand inside. A beam, frame, or piece of trim can look intact until pressure causes the surface to break. Waiting for obvious damage is not a reliable plan. Frass gives you a chance to respond while the visible clue is still small.
What to Do When You Find Termite Poop
Start by documenting the area before you clean it. Take photos of the pile, nearby wood, and the room where you found it. Place a coin beside the pellets to show their size.
Look directly above the pile for small holes, damaged finishes, loose trim, discarded wings, or cracks in the wood. Avoid prying the surface open because breaking into a gallery can scatter evidence and make the source harder to evaluate.
After taking photos, clean the pellets and note whether they return. Record the date and exact location. This information can help an inspector determine whether new material is appearing.
Check nearby rooms and wooden objects as well. Pay close attention to windowsills, baseboards, attic framing, cabinets, door trim, and furniture. One pile may not be the only sign.
Do not apply household sprays or seal the opening before the area is inspected. Surface products may affect a few exposed termites without reaching the colony hidden inside the wood.
How Professional Termite Treatment Addresses the Source
Termite treatment should match the species and the location of the activity. Drywood and subterranean termites do not live the same way, so a single approach does not fit every home.
Drywood termite treatment may focus on specific boards, beams, furniture, or structural voids. Subterranean termite control focuses on the connection between the colony, soil, and structure. Treatment may involve bait stations, foundation trenching, bath traps, or other measures based on the way the home was built.
A professional inspection also looks beyond the visible pile. Technicians check nearby wood, attics, crawl spaces, foundations, and other areas where termite evidence may appear. This helps determine whether you are dealing with one affected object or a broader structural problem.
Protecting Your Louisiana Home After Finding Termite Droppings
Termite poop is easy to dismiss because it looks harmless. A few small pellets do not create the same reaction as a swarm of insects, but they may be the only visible evidence of termites living inside nearby wood.
Take photos, inspect the surrounding area, and note whether the pile returns. Do not assume the colony is inactive because you cannot see termites, and do not assume your home is clear of other termite species when no frass is present.
LaJaunie’s Pest Control can identify the termite species, locate affected areas, and recommend a treatment that fits your home. A professional inspection turns a small, confusing pile into useful information and helps you address the source before hidden damage has more time to spread.
