What Do Termite Droppings Actually Look Like?
Termite droppings, called frass, look like tiny six-sided pellets roughly the size of ground pepper or fine sand, not sawdust. Drywood termites push frass out of small "kick-out holes" in wood as they tunnel, and the pellets pile up in tiny mounds below those holes. Subterranean termites, the more common species across most of Frontline's service area, rarely leave visible droppings at all, since they use their waste to help build the mud tubes they travel through instead.
Drywood Termite Pellets Are Hexagonal and Dry, Not Sawdust
A drywood termite pellet has six flat sides, a rounded shape, and a matte, sandy texture when you look at it closely. The color ranges from light tan to dark brown depending on the wood the termites are eating. Because the pellets are dry and uniform, a small pile of them looks more like spilled coffee grounds or fine sand than the curled, stringy shavings you'd get from a drill or saw.
Myth: Termite Droppings Look Like Sawdust
Sawdust-like debris under a wood surface usually points to carpenter ants, not termites. Carpenter ants don't eat wood, they excavate it to build nests, so the debris they push out contains actual wood shavings mixed with dirt, insect parts, and pieces of dead ants. Termite frass never contains wood fragments, since termites digest the wood rather than discarding it. If the pile looks fibrous or mixed with visible wood chips, an ant colony is the more likely source. The University of Florida's entomology extension has detailed photos comparing drywood termite pellets to other wood-damage signs if you want a closer look.
Subterranean Termites Leave Mud Tubes, Not Pellet Piles
Subterranean termites need constant moisture, so they build pencil-width mud tubes along foundations, piers, and walls to travel between the soil and the wood they're feeding on, rather than tunneling through dry wood and expelling pellets. Finding a mud tube is the subterranean equivalent of finding drywood frass: both are the visible sign of an infestation that's otherwise hidden inside the structure.
| Sign | What's Actually Happening | Most Likely Pest |
|---|---|---|
| Tiny hexagonal pellets, sand-like | Waste pushed out of a kick-out hole in dry wood | Drywood termites |
| Sawdust mixed with insect parts | Wood excavated to build a nest gallery | Carpenter ants |
| Pencil-width mud tubes on foundation | A travel route built between soil and a food source | Subterranean termites |
| Small kick-out holes in trim or furniture | Exit points drywood termites use to expel frass | Drywood termites |
What to Do If You Find Termite Droppings
Leave the pile where it is and photograph it before cleaning anything up, since a technician can often narrow down the species and the likely nest location from the pellets alone. Check nearby wood for small, round kick-out holes, and note whether new pellets appear in the same spot over the next few days. That reappearance is a stronger signal of active feeding than the first pile you find, since an old, undisturbed pile could be left over from a colony that's no longer active in that exact spot.
Worth checking first: frass shows up on horizontal surfaces below the damage, not on the damaged wood itself. Look on windowsills, in furniture drawers, on baseboards, or on the attic floor below exposed rafters.
Common Questions About Termite Droppings
Can I tell how big a termite colony is from the amount of frass?
Not reliably. A small pile can come from a colony that's been active for years in one piece of wood, while a larger pile sometimes just means the kick-out hole is in a more visible spot. A full inspection of the surrounding wood is the only way to gauge the extent of the damage.
Does finding frass always mean I have an active infestation?
Usually, yes, since drywood termites continuously clear pellets from active galleries. A pile that keeps reappearing after you sweep it away is the clearest confirmation. A pile you find once and never see again is worth a professional look, but it's less urgent than active, ongoing frass.
Is termite frass dangerous to touch or breathe?
No. Termite frass isn't toxic and doesn't carry disease, unlike some rodent droppings. It's safe to photograph and sweep up, though wearing gloves is a reasonable precaution any time you're cleaning up pest debris.
Why don't I see any droppings even though I suspect termites?
Subterranean termites, the species most common across Frontline's service area, don't expel visible pellets the way drywood termites do. Look for mud tubes along the foundation instead, or watery, blistered paint on wood surfaces, which often points to subterranean activity underneath.
