Most people book their first termite inspection after seeing something they cannot un-see: a line of mud running up the garage wall, a skirting board that gives way under a thumbnail, or a heap of discarded wings on the window sill the morning after rain. By the time any of those appear, a colony has usually been feeding somewhere nearby for years — which is the entire argument for inspecting a house on a schedule rather than on a fright. This is what an inspection actually involves, what it can and cannot prove, how to read a free one without being sold to, and how often a Malaysian house genuinely needs one.

What happens during a termite inspection?

Less drama than people expect. Nobody drills the floor or opens a wall. A proper inspection is a systematic walk with three simple tools and a fixed order of places, and the order matters more than the equipment.

• A torch. Most termite evidence is in the dark and at ankle height, which is why so much of an inspection happens on hands and knees along skirting boards.
• A probe or screwdriver, for sounding. Tapping along timber and listening for the change from solid to hollow or papery. Sound timber knocks back at you; timber that has been eaten from the inside does not.
• A moisture meter. Subterranean termites carry moisture with them and need humid conditions, so an unexplained damp patch inside a wall is one of the few ways to detect activity behind a surface without opening it. Readings above roughly 20% are the ones that make a technician slow down.

For a normal terrace or semi-D, budget 45 minutes to an hour and a half. A large landed property with a mature garden and a lot of timber takes longer, and an apartment above the podium levels usually takes twenty minutes, because most of the risk simply is not there.

Where does the technician actually look?

In Malaysia the target is overwhelmingly the subterranean termite — mainly Coptotermes gestroi and Coptotermes curvignathus — which nests in or under soil and reaches the building through mud tubes and through the gaps where pipes and cables enter. So the inspection follows the route, not the timber alone:

• The soil line outside. Where render meets ground, along the perimeter, around the porch slab, at the base of pillars, and anywhere a planter box, timber fence post or stack of firewood touches soil against the wall.
• Service entries. Water pipes, air-conditioner drain lines, conduit — the openings that were sealed once, during construction.
• Skirting boards and architraves, room by room, sounded rather than looked at.
• Door and window frames, especially at the bottom 30cm where the frame meets the floor.
• Wet-area walls. Bathrooms, the kitchen sink wall, the utility yard. Moisture and timber together is the combination that matters.
• Built-in cabinetry and the underside of stairs, which are enclosed, undisturbed and made of exactly what termites want.
• The roof void, wherever there is a hatch and it is safe to enter.

The detail that decides where treatment goes. Finding activity is not the end of the inspection — finding the trail is. Nomobug installs baiting stations directly on the active trails, which in Malaysian homes are usually inside the house rather than out in the garden, and a technician who has not traced the trail cannot place them properly.

What can an inspection not see?

This is the part that reputable companies say up front and the rest leave to the small print.

A standard inspection is non-destructive. Nobody is opening a wall cavity, lifting intact floor tiles, or pulling out fixed cabinetry on a first visit, which means a colony working inside a sealed cavity can be genuinely undetectable on the day. The moisture meter helps, but it reads moisture, not termites — a damp wall is a reason to look harder, not proof of anything.

Two more honest limits. Access decides coverage: no roof hatch means no roof void, and a store room packed to the ceiling means the skirting behind it was not checked. And a moisture meter contributes nothing at all against drywood termites, which do not bring moisture with them — they are much less common in Malaysian homes than subterranean species, and they leave hard gritty frass rather than mud tubes. The difference between the two is covered in drywood vs subterranean termites.

So the correct reading of a clear inspection is “no activity was visible or detectable today in the areas that could be accessed” — not “this house has no termites”. Anyone who tells you the second thing is overselling the first.

What should you get afterwards?

A finding, not just a figure. The two are different things and the gap between them is where most complaints about this trade live.

A usable inspection outcome tells you: where activity was found, with photographs; what it looks like — mud tubes, hollow timber, live workers, damage only; which areas were checked; which areas could not be accessed and why; and what is recommended, with the reasoning. If you get a number and a verbal “quite bad already, better do it now”, you have been quoted, not inspected.

A homeowner in Rawang called us after another company told her the whole house needed a soil treatment because of “termites in the walls”. We went through it room by room. There was one active trail running up behind the kitchen door frame from a gap where the water pipe entered, and nothing anywhere else — no tubes on the perimeter, no hollow skirting in any other room, roof void clean. We put baiting stations on that trail, topped them up every two weeks, and it was done in about seven weeks. She had been quoted for a full perimeter job on a colony that was using one pipe entry.

Is a free termite inspection worth having?

Yes, provided you read it for what it is.

A free inspection is a sales visit by a company that would like the treatment job. That is a perfectly normal way for this trade to work — we do exactly that for commercial enquiries, where a business premises cannot be quoted sensibly without walking it. It is not dishonest. It is simply not an independent audit, and it should not be treated as one when the same visit produces both the diagnosis and the quote.

What makes one useful to you:

• Ask for the findings in writing, with photos and locations, whether or not you buy anything. A company confident in its inspection will send them.
• Ask what could not be accessed. The answer tells you how thorough the visit was.
• Ask which species and where the trail runs. “Termites lah” is not a finding.
• Get a second look before a five-figure decision, exactly as you would for anything else at that price.

The one number to be genuinely suspicious of: RM199 the moment you say anai-anai. Corrective termite work does not cost that, and a price offered before anyone has traced a trail is a price for something other than the job you need. More on that in cheap pest control red flags.

And our own position, since this article would be hollow without it: Nomobug does not do free residential inspections. Home quotes are fixed on WhatsApp from photos and a description, with no site visit needed to price the work, and a pre-inspection is arranged on request when the case calls for one. Commercial enquiries get a free site inspection. It is a deliberate split, and it exists so nobody pays for a technician’s travel time inside a treatment price.

How often does a Malaysian house need one?

Once a year is the sensible default, and the reason is climate. In temperate countries termite activity has a season. Here it does not — Coptotermes works through the calendar, which is why an annual check catches things at a stage where a baiting programme handles them rather than a carpenter.

Move it up the list if:

• The house is landed and more than about 15 years old, particularly with timber staircases, parquet or built-in cabinetry.
• Anything timber touches soil — fence posts, a pergola, planter boxes against the wall, a garden shed.
• A neighbour on your row has just been treated. Colonies do not respect the boundary wall.
• You had a swarm indoors, even months ago and even if it stopped.
• An existing soil treatment warranty is within a year of expiring.
• You are buying the house — see checking a second-hand house for termites.

An apartment on an upper floor is the genuine exception. Unless there is a known problem in the block or a lot of timber in the unit, the annual habit is not doing much for you there.

What does it cost — and what does treatment cost?
