Found Termites in Your House? Here's What to Do First

The single most useful thing you can do in the first ten minutes is nothing. Don't spray it, don't break it open, don't scrape it off the wall. What you're looking at is evidence, and how you handle it in the next few minutes decides how straightforward the rest of this gets.

Timber damaged from the inside by subterranean termites

How to tell it's actually termites

Most people don't find termites. They find something else and work backwards: a skirting board that sounds hollow, paint blistered in a strange line, or a scatter of translucent wings on the floor after a storm. The insects themselves stay hidden, which is precisely what makes them expensive.

Four signs are worth knowing:

Mud tubes. Pencil-width tunnels of soil and saliva running up a wall, a pillar, or the outside of a foundation. Subterranean termites dry out and die in open air, so they build covered highways between the soil and their food. A mud tube is the clearest single indicator there is.

Mud tubes are the clearest single sign of subterranean termites. Leave them intact.

Hollow-sounding timber. Termites eat wood from the inside out, following the grain and leaving the outer surface intact. Tap along a skirting board or door frame with a knuckle. Infested sections sound papery and thin compared with solid ones.

Blistered or rippled paint. Where termites have eaten close to the surface, paint and plaster lose their backing and start to bubble. It's easily mistaken for damp, and in a humid climate it usually gets mistaken for exactly that.

Discarded wings. After heavy rain, mature colonies release winged reproductives to start new nests. They fly, land, shed their wings and crawl off. You rarely see the insect. You see the wings, small and equal-sized and slightly iridescent, collecting along windowsills and under lights.

Shed wings after heavy rain usually mean a colony is swarming nearby.

Termites or flying ants?

This is the most common misidentification, and locally the winged termites are usually called kelkatu. Three features separate them reliably:

If there's a pile of shed wings and no insects to be seen, that's termites. Ants don't shed wings the same way.

What a swarm actually means

The winged termites are called alates. They are reproductives, produced by a colony that has reached maturity, and their job is to leave, mate, and start colonies of their own. Guides written for Europe or North America will tell you this happens in the warmer months. In Sabah there is no cool season for the weather to warm up from, so the trigger here is heavy rain and humidity rather than temperature, which is why swarms tend to follow a downpour.

A swarm indoors tells you a mature colony is somewhere within flying range. That is not the same as saying it is inside your house. It might be under your floor, in a neighbouring unit, or in a tree stump on the boundary. Working out which of those it is takes an inspection, but seeing alates indoors does mean an established colony is close enough to matter.

Why termites are relentless in Sabah

Termite advice written for Europe, Australia or the northern United States assumes a seasonal rhythm. Colonies slow in winter, activity picks up in spring, and inspections get scheduled around it. None of that applies here.

Kota Kinabalu is warm and humid year-round. There's no cold season to suppress colony activity and no extended dry period to make soil inhospitable. A subterranean colony that establishes near a Sabah property feeds continuously, every month of the year. So "we'll look at it after the rainy season" isn't a delay of a few dormant months. It's a delay of continuous feeding.

Colonies also outlast the people worrying about them. Workers and soldiers live roughly one to two years, but the king and queen survive for decades, with the longest-lived queens reported at thirty to fifty years. A colony does not age out or wander off. Left alone, it keeps producing replacements for every worker that dies, and it keeps feeding.

Local context

Building style matters as much as climate. Older kampung houses with timber structural elements in ground contact, shoplots sharing party walls with neighbouring units, and ground-floor condominium units backing onto landscaped soil each present a different entry problem. Shared walls in particular mean a neighbouring unit's untreated infestation is your problem too.

Five things to do right now

1. Leave it alone. Don't spray it, don't break the tubes, don't scrape anything away. Every one of those makes the next step harder, for reasons covered below.

2. Photograph it. Several shots. One close enough to show detail, one wide enough to show where in the room it is. If you disturbed anything before reading this, photograph it anyway. It still helps.

3. Note exactly where it is. Which wall, which floor, how far from an external door or a wet area like a bathroom or kitchen. Termites enter along predictable routes, and the location of what you found narrows down where to look.

4. Check the rest of the property, gently. Tap skirting boards, door frames and window frames on the same floor, especially near bathrooms, kitchens and any wall meeting soil outside. You're building a picture of extent, not attempting a survey.

5. Get it identified before anything is treated. Different termites live differently, and the treatment that suits one is wasted on another. Identification comes first, because everything else depends on it.

Mistakes that make it worse

Spraying what you can see

The termites visible to you are a tiny fraction of the colony, and the nest is usually in soil some distance away. Insecticide kills the foragers in front of you and never reaches the nest. Worse, the colony registers the disturbance, seals that route and reopens somewhere else in the structure, often somewhere you can't see. You've spent money, lost the trail, and made the property harder to treat properly.

Breaking open the mud tubes

Understandable, and counterproductive. Intact tubes tell an inspector the direction of travel and roughly how active the route is. Broken ones tell them very little, and the colony simply rebuilds elsewhere.

Assuming a repair is a solution

Replacing a damaged skirting board or door frame addresses the symptom. If the colony still has access, the new timber is just fresh food. Repairs belong after treatment, not instead of it.

What a professional inspection involves

An inspection is diagnosis, not treatment. The purpose is to establish four things: whether the activity is live or historic, which species is involved, how far it extends, and where the colony is likely accessing the building from. Only once those are known does it make sense to talk about treatment. That is the part where judgement matters, because choosing the wrong approach for the species and the building can mean paying for a treatment that was never going to work.

Common questions

Should I spray termites I find in my house?

No. The termites you can see are a small fraction of the colony, and the colony itself is usually in the soil somewhere else entirely. Spraying kills the visible workers without touching the nest. It also teaches the colony to avoid that area, so they seal off the route and reopen somewhere you cannot see. That makes the infestation harder to trace and harder to treat, and you lose the evidence an inspector needs.

Are the flying insects that appear after heavy rain termites or ants?

Look at three things. Termite swarmers, called kelkatu locally, have straight bead-like antennae, a thick body with no narrow waist, and four wings of equal length that snap off easily. Flying ants have elbowed antennae, an obviously pinched waist, and front wings noticeably longer than the back pair. A pile of shed wings on a windowsill or floor after rain almost always means termites, not ants.

What does it mean if I see flying termites in my house?

It means a mature colony is within flying range and has released reproductives, called alates, to start new colonies. It does not automatically mean the colony is inside your house, because alates travel some distance before landing. In Sabah these swarms usually follow heavy rain rather than a change of season. Either way it is worth having the property checked, because a colony only produces alates once it is well established.

How quickly do termites damage a house?

Damage is gradual rather than sudden, but it is continuous, and in Sabah it does not pause for a dry season. A mature subterranean colony contains hundreds of thousands of individuals feeding around the clock. Most owners only notice once a skirting board gives way or a door frame goes soft, and by that point the termites have usually been active in the structure for many months.

When this needs a professional

If you've found mud tubes, hollow timber, or shed wings indoors, the honest answer is now. Not because the situation is an emergency, but because everything about it gets more expensive with time and nothing about it resolves on its own. A colony doesn't move out.

What you gain by having it looked at early is mostly information: whether it's active, what species, how far it's spread, and whether it needs treating now or monitoring. Sometimes the answer is that it's old damage and nothing is currently living there. That's worth knowing too.
