7 Signs of Termites in Your Home (Singapore)

Termites are among the most expensive pests a Singapore home can face, precisely because they work out of sight. They eat timber from the inside out and can do serious structural damage long before anyone notices a thing. In Singapore’s warm, humid climate they stay active year-round — there’s no cold season to slow them down — so knowing the early warning signs of termites can save you thousands in repairs and a great deal of stress. This guide walks through the seven signs every homeowner should recognise, explains what each one tells you, and sets out exactly what to do if you spot them. Catching termites early is the whole game; the damage compounds quietly the longer they’re left.

1. Mud tubes

Pencil-width tunnels of dried mud running up walls, across skirting or along foundations are the classic signature of subterranean termites — the most common and destructive type in Singapore. They build these tubes to travel between the soil (where they nest and stay moist) and the timber they’re feeding on. If you find a mud tube, break a small section open: if it’s repaired within a day or two, the colony is active. Subterranean termites are also why the soil around and beneath a building matters so much in treatment — more on that in subterranean vs drywood termites.

2. Hollow-sounding wood

Tap along door frames, skirting boards, parquet and wooden furniture. Because termites hollow out timber from within while leaving a thin outer layer intact, affected wood gives a hollow, papery sound rather than a solid knock. You may also find that a screwdriver pushes easily into wood that should be firm. This is one of the most reliable DIY checks, and worth doing periodically around the parts of the home where timber meets the floor or wall.

3. Discarded wings

After a colony swarms to start new nests, the winged termites (alates) shed their wings, leaving small piles of equal-length, translucent wings near windowsills, light fittings and door frames. Often these piles appear *before* anyone has actually seen the insects, making them an early tip-off. Swarming usually follows rain, and seeing winged termites or their shed wings indoors suggests a colony is mature and nearby — see flying termites in Singapore for what a swarm means and how to respond.

4. Frass (drywood termite droppings)

Tiny, ridged, pellet-like droppings — often the colour of sawdust or coffee grounds — collecting beneath furniture, skirting or timber point to drywood termites, which live inside the wood itself rather than in the soil. They push this frass out of small “kick holes”, so a little pile that keeps reappearing after you sweep it away is a strong clue. Drywood termites are common in furniture and roof timbers; our guide to drywood termites in Singapore covers how they differ from the subterranean kind.

5. Bubbling or cracked paint

Paint that blisters, bubbles or cracks for no obvious reason can signal moisture and termite activity in the wood beneath — termites bring moisture with them, and the surface distorts as a result. It’s easy to mistake this for ordinary damp, so it’s worth investigating rather than just repainting over it, especially if it appears alongside any of the other signs here.

6. Tight-fitting doors and windows

Doors and windows that suddenly stick or feel tight can be a symptom of termite damage and the moisture that comes with it, as frames warp out of true. Singapore’s humidity swells timber anyway, so this sign is only meaningful in combination with others — but a door that’s newly hard to close, paired with hollow-sounding wood nearby, deserves a closer look.

7. Live termites

Finally, the termites themselves: pale, soft-bodied, ant-like insects found in damp areas, behind skirting or inside affected timber. The most common mistake is confusing them with ants. Termites have straight, bead-like antennae, a thick waist and two pairs of equal-length wings, whereas ants have elbowed antennae, a pinched waist and unequal wings. Our guide to termites vs ants makes the distinction clear, because treating one as the other wastes time while the colony grows.

What to do next

Termite damage compounds quickly, and DIY surface sprays don’t reach the colony — they kill a few workers while the nest carries on. If you spot any of these signs, the right move is a professional termite inspection before the colony spreads, followed by proper treatment such as baiting or a soil barrier rather than a can of insecticide. It’s also worth understanding what an inspection involves and what treatment costs depend on, so you know what to expect rather than being surprised — see termite inspection: what to expect and termite treatment cost in Singapore, which depends on the species, the size of the property and the extent of the infestation. And once you’re clear, our guide on how to prevent termites helps keep them from coming back.
