What Do Termite Droppings Look Like? How to Spot Drywood Termite Frass

Small piles of hard pellets on a windowsill, floor, or beneath wooden furniture can be a sign of drywood termites. The material may resemble sawdust or ordinary debris, making it easy to overlook.

These pellets are called termite frass. Recognizing what they look like and where they collect can help you decide when to arrange an inspection. A professional assessment can confirm whether termites are responsible and help determine the next steps.

What Drywood Termite Frass Is and Where It Comes From

"Frass" is the term commonly used for drywood termite droppings. Drywood termites live and feed inside the wood they infest. As they digest the wood, they produce small, hard pellets that they push out through tiny openings in the wood surface.

These openings are often called kickoutholes. The pellets can accumulate beneath the opening, sometimes forming a small pile on a windowsill, floor, or other surface.

Subterranean termites differ in how they live and leave evidence. They travel between the soil and their food source and may create mud tubes along foundations or other surfaces. A pile of loose, hard pellets is more consistent with drywood termite frass, although the material should be assessed in context.

The University of California Statewide Integrated Pest Management Program's guide to drywood termites describes the characteristic shape of drywood termite pellets and explains how these termites infest wood. Knowing these differences can help homeowners recognize a possible problem, but visual clues alone do not confirm an active infestation.

What Termite Droppings Look Like Up Close

Drywood termite pellets are tiny, firm, and usually uniform in shape. They are often compared to grains of sand because of their small size. Under closer inspection, the pellets typically have distinct sides rather than the soft, irregular texture associated with ordinary dust.

Their color can range from pale tan to brown or darker shades, depending partly on the wood being consumed. Pellets may appear in a compact pile directly beneath a small opening or scatter across a nearby surface.

Several clues can help you distinguish possible termite frass from other debris:

• Distinct pellets: Frass consists of small, separate particles rather than fine powder.

• A small, repeated pile: Pellets may collect beneath an opening in wooden material.

• A nearby kick out hole: A tiny hole above the pile may indicate where the termites expel the pellets.

• Evidence that returns: If pellets reappear after being cleared, termite activity may be ongoing and deserves assessment.

Sawdust usually looks more fibrous or powdery and may contain irregular wood fragments. Other insects and household debris can also leave particles that look similar to termite frass. Avoid relying on color or appearance alone to identify the source.

If you discover suspicious pellets, take a clear photo and note where they appeared. Leaving the material undisturbed until an inspection can preserve useful evidence for the specialist.

Where to Look for Termite Droppings in Your Home

Drywood termite frass may appear anywhere infested wood is present. Some locations are easier to check because pellets fall onto visible, horizontal surfaces.

Windowsills and window frames

Windowsills can collect pellets expelled from nearby wooden frames. Check for small piles, tiny openings, or changes to the surrounding wood.

Baseboards and door frames

Wooden trim and door frames may conceal termite activity. Inspect the surrounding floor and the base of the trim for unusual pellets or signs of deterioration.

Attics and exposed framing

Roof framing and other exposed wood can provide useful areas to inspect. If you can access the attic safely, look for piles beneath wooden components. Do not enter unsafe or restricted spaces to investigate.

Wooden furniture and cabinets

Drywood termites can infest furniture and other wooden items. Small piles below a piece of furniture may warrant a closer look, especially if there are tiny holes or signs of damaged wood.

Floors and shelves beneath wooden features

Pellets may fall onto nearby floors, shelves, or other surfaces. Their location can offer a clue about the source, although a specialist may need to inspect the wood above them to confirm the cause.

If you find a suspicious pile, look for nearby openings without scraping or cutting into the wood. Our guide on what termite damage looks like on wood explains other signs that may help you recognize a potential infestation.

What to Do When You Find Drywood Termite Frass

Finding possible termite droppings does not automatically tell you how extensive the activity is. The next step is to preserve the evidence and arrange an inspection.

1. Photograph the pellets and their location.

Take a clear picture of the pile and the surrounding wood. Include nearby windowsills, trim, furniture, or other features that may help the inspector understand where the material appeared.

2. Avoid disturbing the suspected source.

Try not to fill, seal, or scrape away the suspected kickout holes before the inspection. If you have already cleaned the pellets, note where they were found and whether they returned.

3. Schedule a professional termite inspection.

A termite inspection can help determine whether the pellets are consistent with termite frass, identify accessible evidence, and assess the likely location of activity. The inspector may also look for other signs of drywood termites and damage to nearby wood.

4. Review the treatment options.

Treatment depends on the termite species, the location of the infestation, and how widely the activity extends. Localized activity may be suitable for a targeted method, while more extensive infestations may require a broader treatment approach.

A tailored termite treatment plan should explain the recommended method and any preparation requirements. If the inspection identifies weakened wood, a separate termite damage repair assessment can help determine whether structural components need repair or replacement.

Protect Your Home With Early Termite Identification

Recognizing possible termite droppings gives you a reason to investigate before more evidence or damage appears. Look for small, hard pellets, check the surrounding wood for tiny openings, and keep a record of where the material appears.

Because frass can resemble other household debris, professional identification is the most reliable way to understand what you have found. Attack Pest Management provides termite inspection, treatment, and damage repair services throughout Los Angeles County.

Frequently Asked Questions

What do termite droppings look like?

Drywood termite droppings are tiny, hard pellets with distinct sides. They may appear in small piles beneath openings in infested wood and can range in color from light tan to brown.

Are termite droppings a sign of an active infestation?

Frass can indicate drywood termite activity, but a pile alone does not confirm whether termites are currently active. Pellets that reappear after cleaning are a reason to arrange a professional inspection.

Where do termite droppings usually appear?

Common locations include windowsills, baseboards, door frames, attic areas, and surfaces beneath wooden furniture. The location can help an inspector identify nearby wood that needs closer examination.

How can I tell termite frass from sawdust?

Termite frass typically consists of small, firm, relatively uniform pellets. Sawdust is often finer, powderier, or more irregular. Since other debris can look similar, have suspicious material assessed by a termite specialist.

Do subterranean termites leave droppings?

Subterranean termites produce waste, but they are more commonly recognized by signs such as mud tubes and damaged wood. Loose piles of hard pellets are more characteristic of drywood termite frass.

Should I clean up termite droppings?

If possible, leave the pellets in place until the inspection and take a photo of the surrounding area. If you have already cleaned them, tell the inspector where they appeared and whether the material returned.
