What Termite Droppings Look Like in Queensland Homes

Termite droppings, also called frass, look like tiny, hard, oval pellets about one millimetre long, similar to coarse sand or coffee grounds. They range from cream to dark brown depending on the timber eaten, and usually collect in small piles beneath windowsills, skirting boards, door frames or roof timbers.

Finding a small pile of gritty specks on the floor is easy to brush off as dust. In Queensland, though, it can be one of the few visible clues that termites are feeding inside your timber. Our warm, humid climate makes South East Queensland one of the highest-risk regions in Australia for termite damage, so knowing what you are looking at matters.

Below, the Pest-Ex team explains what termite droppings look like, which termites leave them, how to tell them apart from other debris, and what to do if you find some.

What do termite droppings look like up close?

Under a magnifying glass, termite frass has a shape that is quite distinctive once you know what to look for:

• Size: each pellet is roughly one millimetre long, about the size of a grain of sand.
• Shape: oval or slightly elongated with rounded ends, and six flattened sides running lengthways, a bit like a tiny ridged capsule.
• Texture: hard and dry. The pellets don’t smear when pressed, unlike the droppings of many other pests.
• Colour: anywhere from pale cream and tan through to reddish brown and almost black. The colour reflects the timber the termites have been eating, so frass from a pine windowsill looks lighter than frass from a dark hardwood beam.
• How it gathers: in neat little mounds or scattered trails directly beneath the timber, often building up again after you clean it away.

From a standing height, most people describe it as looking like sawdust, ground pepper, coarse sand or spilled coffee grounds. That is exactly why it gets swept up and forgotten.

Which termites leave droppings you can see?

This is the part many homeowners don’t realise. Not every termite leaves visible droppings, and the type you find tells you a lot about what is going on.

Drywood termites leave pellet piles

Drywood termites live entirely inside dry timber and don’t need contact with soil. To keep their tunnels clean, they push their droppings out through tiny “kick-out” holes in the surface of the wood. The pellets fall and pile up below, which is where the classic frass mounds come from.

In Queensland, the main drywood species of concern is the West Indian drywood termite (Cryptotermes brevis). It is a restricted invasive pest under Queensland biosecurity law, and suspected infestations must be reported to Biosecurity Queensland on 13 25 23. Finding pellet-shaped droppings in your home is a good reason to get a professional identification quickly.

Subterranean termites hide their droppings

Subterranean termites cause most of the termite damage in Queensland homes, and they behave very differently. They nest in the soil and travel into buildings through hidden tunnels and mud leads. Rather than pushing droppings out, they mix their waste with soil and saliva and use it as building material.

That means subterranean termites rarely leave piles of pellets. Instead, look for:

• mud tubes running up walls, stumps, piers or slab edges
• soil-like “mudding” packed into cracks, joints or small holes in timber
• skirting boards, architraves or door frames that sound hollow when tapped
• paint that bubbles or cracks over timber

So a lack of droppings doesn’t mean your home is termite-free. In South East Queensland, the more common and more destructive species often leaves no frass at all.

Where to look for termite droppings in your home

Frass tends to collect directly below the timber the termites are feeding in. When checking a Queensland home, pay close attention to:

• Windowsills and window frames, particularly timber frames in older Queenslanders and post-war homes
• Skirting boards and architraves, along the floor line where pellets can gather unnoticed
• Door frames and thresholds
• Timber furniture, especially older pieces or items bought second-hand
• Roof space timbers, where pellets may drop onto ceiling insulation or the tops of cornices
• Exposed beams, decks and timber stairs

Look for small round holes in the timber just above the pile. These are often sealed with a thin paper-like plug, so they can be hard to spot.

Termite droppings vs other things that look similar

Plenty of debris around the house can pass for termite frass. Here is how to tell the difference.

Sawdust from borers. Wood-boring beetles such as the furniture beetle leave a fine, flour-like powder, often with round exit holes in the timber. Borer dust feels soft and powdery, while termite frass feels gritty and holds a distinct pellet shape.

Ant debris. Some ants nest in damp or rotting timber and push out shavings mixed with insect parts. Ant debris looks fibrous and irregular, not like uniform pellets.

Cockroach droppings. Small cockroaches leave dark specks that look like ground pepper, often with brown smear marks along walls and inside cupboards. They tend to appear in kitchens and bathrooms rather than below timber. If that sounds more like your problem, see our cockroach control service.

Rodent droppings. Mouse and rat droppings are much bigger, roughly the size of a grain of rice or larger, dark and tapered at the ends.

General dirt and grit. Dust from outside is uneven in size and shape. If you sweep the area and pellets reappear in the same spot within days, that points strongly to termites.

What to do if you find termite droppings

If you think you have found termite frass, the first steps are important:

1. Don’t sweep it all away. Take clear photos and, if you can, collect a small sample in a sealed bag or container.
2. Don’t spray or poke the timber. Disturbing the area or spraying household insecticide can drive termites deeper into the structure and make them harder to find.
3. Check the surrounding timber for tiny holes, blistered paint or a hollow sound, without breaking into it.
4. Report suspected drywood termites to Biosecurity Queensland if the droppings are pellet-shaped.
5. Book a professional termite inspection so the species and extent of activity can be confirmed.

A licensed technician can tell the difference between active and old activity, and can identify whether you are dealing with drywood or subterranean termites. That decides the right treatment.

How Pest-Ex inspects for termite activity

Termites work out of sight, so what you see on the surface is often a small part of the picture. During a termite inspection, our technicians use Termatrac radar to detect termite movement inside walls and timber without drilling. FLIR thermal imaging also helps pick up the heat and moisture patterns that termite nests and leads create.

We check the interior, roof void, subfloor and the yard, then explain what we found, including any conducive conditions such as moisture problems or timber touching soil. If you have spotted winged insects around your lights as well, read our guide to flying termites and what they mean for your home.

Frequently asked questions

Are termite droppings common in Brisbane homes?

Visible termite droppings are less common than mud tubes in Brisbane, because the subterranean termites that cause most local damage don’t push their waste out of the timber. Pellet piles usually point to drywood termites, which should be identified by a professional and reported to Biosecurity Queensland.

What colour are termite droppings on the Gold Coast?

Termite droppings take on the colour of the timber being eaten, so they can be cream, tan, reddish brown or nearly black. Frass from lighter pine framing in Gold Coast homes often looks sandy, while frass from hardwood looks darker.

Can I just clean up termite droppings and wait?

It is not a good idea. If the pellets come back after cleaning, termites are likely still feeding in the timber. Photograph the droppings, keep a sample and book a termite inspection rather than waiting for damage to show.

Do termite droppings mean my house has active termites?

Fresh piles that keep reappearing usually mean active termites. Old frass from a past infestation can sit in wall cavities or roof spaces for years, so a technician needs to check whether the activity is current.

Are termite droppings harmful to my family?

Termite frass is not considered toxic, though it may irritate people with dust allergies. The bigger risk is the damage the termites themselves can do to your home’s timber.
