The reason termites are so destructive isn’t that they eat fast — it’s where they hide. So when people ask where do termites hide in a Malaysian home, the honest answer is the same five spots almost every time: roof trusses, door and window frames, under parquet flooring, behind skirting boards, and inside hollow doors and built-in cabinets. Subterranean termites travel up from the soil through your wall cavities and eat timber from the inside out, so the surface looks perfectly fine until the day it doesn’t. By the time most homeowners notice, the colony has usually been feeding for 3 to 5 years.

First, a quick distinction that changes where you look. Two kinds of termite matter in Malaysia. Subterranean termites (mostly Coptotermes) live in a soil-based colony with a queen, build mud tubes to reach your timber, and do the overwhelming majority of structural damage. Drywood termites live entirely inside the wood they eat, need no soil contact, and leave tiny pellet droppings called frass. Most of the hiding spots below are about the subterranean kind — the ones quietly working through the bones of your house.

1. Roof Trusses and Rafters

Almost nobody climbs into their own roof space. That’s exactly why termites love it. In older terrace houses the roof is held up by timber trusses and battens, and subterranean termites will track all the way up an internal wall cavity to reach them. Up there it’s warm, undisturbed, and full of cellulose.

The damage hides above your ceiling boards until a truss weakens and the ceiling starts to sag or stain. If you have roof access, look for mud tubes running along the brickwork into the timber, and tap the rafters near the wall plate — that join is where they usually start.

2. Door and Window Frames

Timber door and window frames are built right into the wall, often with the bottom of the frame close to the floor slab. That makes them an easy bridge from the soil into your home. Both subterranean and drywood termites go for frames, and it’s one of the few spots where you can actually catch them early.

The tells are practical. A door that suddenly sticks in its frame when it used to swing freely. Paint on the architrave that ripples or bubbles. A frame that gives slightly when you press it with a thumb. If pressing it leaves a dent or breaks through, the timber inside is already gone.

3. Under Parquet and Timber Flooring

Parquet sits directly on the floor slab, often with a layer of adhesive termites are happy to eat through to reach the timber. Because the slab is in contact with the ground, subterranean termites can come straight up through an expansion gap or a hairline crack and start on the underside of the wood — the side you never see.

What you’ll notice first is a few blocks that feel spongy underfoot, or that lift slightly. Sometimes a faint hollow sound when you walk a certain patch. By then the layer beneath is usually honeycombed. Parquet damage is a classic late catch, which is why floors are part of any proper inspection.

4. Behind Skirting Boards

The join where the floor meets the wall is a termite motorway, and the skirting board covers it like a curtain. Behind it, termites build mud tubes straight up out of the slab and into the wall, completely out of sight. It’s one of the most common places we find live activity on an inspection.

Run your eye along the bottom of your skirting, especially in bathrooms, the kitchen, and any room that backs onto a garden or drain. Look for thin lines of dried mud, small bubbled patches in the paint, or a section that sounds different when tapped. A skirting board that flakes away in papery layers has already been hollowed.

5. Hollow Doors and Built-In Cabinets

Built-in wardrobes, kitchen cabinets, and hollow-core doors give termites two things at once: cellulose to eat and a dark, still place to do it. Kitchen and bathroom cabinets are the worst because they add moisture — and moisture is what subterranean termites are always chasing.

Open the cupboards you rarely use and look at the back panels and the corners against the wall. Drywood termites give themselves away with little piles of pellet frass that look like fine sawdust or coffee grounds. If you sweep it up and it returns in a day or two, something is living in that timber.

The Early Signs to Watch For

You don’t need to find the termites themselves — you need to spot what they leave behind. Across all five hiding spots, the same handful of signs keeps showing up.

The five tells. Mud tubes (pencil-thin mud trails on walls or foundations). Hollow or papery sound when timber is tapped. Rippled, bubbling or sunken paint. Doors and windows that suddenly stick. Discarded wings or pellet frass near windowsills and skirting after rain. Spot any one of these and it’s worth an inspection.

One rule matters more than the rest: if you find a mud tube, do not break it open. It tells the technician where the termites are travelling and roughly how active the colony is. Breaking it just sends them deeper and loses you the evidence. For a fuller read on this, see our guide on termite treatment and how it works.

What Treatment Costs

Termites are not a DIY job — a shop spray does nothing to a colony living in the soil and your walls. Treatment is priced separately from general pest control, and there are two main approaches.
