What Do Termite Droppings Look Like?

Key Takeaways

• What it looks like: Termite droppings (frass) are tiny, oval pellets. They can look like sawdust, coffee grounds, or salt and pepper.

• Where to find it: Look for piles near window sills, door frames, baseboards, and attics.

• Is it dangerous?: The droppings aren't toxic but can trigger allergies. The real threat is the termites eating your house.

• What to do next: Don't just sweep it up. If you see frass, call a pest control professional.

Termite frass looks different depending on the species of termite living in your home. Because different species require different treatment methods, knowing what to look for is a critical first step in taking back your space.

Drywood Termite Frass

Drywood termites are the most common culprits when it comes to visible indoor droppings. When these termites establish a nest, they seal themselves inside the wood to find food, water, and shelter. As they consume the wood, they quickly run out of space inside their tunnels. To keep their living quarters clean, they create tiny "kick-out holes" to push their fecal pellets out of the nest.

Drywood termite pellets are incredibly small, usually only about one millimeter in length. If you look closely (or use a magnifying glass), you will notice that each hard, dry pellet is an oval-shaped capsule with six concave sides and rounded ends.

Depending on the color of the wood the termites are eating, drywood frass can range from light tan to dark brown or black. Because they push the waste out of small holes, the droppings typically form small, cone-shaped mounds that look like scattered sand or sawdust.

Subterranean Frass

Subterranean termites generally do not leave behind visible droppings. The first sign of a termite infestation may be wormlike mud tunnels that run up walls or foundations. Subterranean termites use their droppings in the construction of tunnels and mud tubes, so their droppings cannot be distinguished from the nest.

Dampwood Termite Frass

Dampwood termites thrive in wet, decaying wood, meaning they are usually found in areas with existing water damage or plumbing leaks. Their droppings are slightly larger and stickier than drywood frass because of the high moisture content. They often stick to the sides of the termite galleries and clump together, making them harder to spot.

Termite Droppings vs. Other Pests & Items

To the untrained eye, termite frass can look a lot like regular household debris or waste from other insects. Here is how to tell the difference:

• Carpenter ants: While carpenter ants also push debris out of their nests, their waste is a messy mix of actual wood shavings, dirt, and dead insect parts. Termite frass consists of uniform, six-sided fecal pellets.

• Cockroaches: Roach droppings look like small smears or black pepper flakes, rather than hard, dry, oval capsules.

• Sawdust: Normal sawdust looks like thin splinters and shavings of wood. Termite pellets are perfectly uniform in shape and size.

Where to Find Termite Droppings in Your Home

Because drywood termites infest structural timber and furniture, their droppings tend to accumulate in quiet, undisturbed areas where wood is exposed. If you suspect an infestation, grab a flashlight and check these common hot spots:

• Window sills and wooden window frames

• Door frames and thresholds

• Baseboards and the edges of hardwood floors

• Attics with exposed wooden beams

• Crawlspaces and basements

• Beneath antique or wooden furniture

Are Termite Droppings Dangerous to Your Health?

Here's the good news: termite droppings, or "frass," aren't toxic to people or pets. Unlike droppings from rodents that can carry nasty diseases, termite frass is really just digested wood. It’s not poisonous, but the fine dust from frass piles can sometimes irritate your respiratory system or kick up allergies if you're sensitive.

However, just because the droppings themselves aren't dangerous doesn't mean you can relax. Finding termite frass is a sure sign that a colony is actively munching on your home's structure. If you ignore it, you could be facing thousands of dollars in damage. The real danger isn't the droppings. It's the termites that leave them behind.

What to Do If You Find Termite Droppings

It is tempting to simply grab the vacuum, suck up the messy pile of pellets, and pretend it never happened. But cleaning up the droppings only removes the evidence. It does absolutely nothing to stop the termites actively destroying your home.

If you spot termite frass, or notice piles of pellets reappearing after you sweep them away, it is time to call in a professional. Don't wait for the damage to spread. Contact Orkin today for a free, comprehensive termite inspection and stop the destruction before it gets worse.
