Have you ever tapped on a piece of timber in your home and noticed it sounds a little off?
That hollow sound could be one of the first clues that something is quietly eating away at your property from the inside out. Termite damage is one of the most expensive problems an Australian homeowner can face, and the frustrating part is that it often goes unnoticed until it’s already severe.
At Bug Busters, we’ve seen firsthand what these tiny insects can do to a home when left unchecked. This guide walks you through exactly what termites and termite damage look like, so you can catch the warning signs early.

What Does a Termite Actually Look Like?
Most people have never seen a termite up close, which makes a termite infestation so easy to miss. Termites are small, pale insects, typically creamy white to light brown in colour, and they actively avoid light. That’s why they’re rarely spotted in the open.
There are a few types you might encounter:
- Worker termites are the most numerous. They’re small, wingless, and soft-bodied, roughly 3 to 4mm long. These are the ones doing the actual damage inside your timber.
- Soldier termites have a darker, larger head and strong mandibles. Their job is to defend the termite colony, not feed on wood.
- Termite swarmers (also called alates or flying termites) are the reproductive members of the colony. They’re the ones you’re most likely to spot, especially during warmer months after rain. They emerge in swarms to form new colonies, and they shed their termite wings shortly after landing.
If you find a cluster of discarded wings near window sills, doorways, or light sources inside your home, don’t brush them off as nothing. That’s one of the clearest early signs of termite activity nearby.

The Most Common Signs of Termite Damage in Your Home
Knowing what to look for can save you thousands. Termites have voracious appetites and can cause significant timber damage long before anything visible appears on the surface. Here are the most common signs of termite damage to watch for:
- Hollow sound when tapping timber: Tap along skirting boards, door frames, or wall panels. If the wood sounds hollow, termites may have eaten through the inside.
- Bubbling or blistered paint: Paint that bubbles without any obvious moisture source can be a sign of termites tunnelling just beneath the surface.
- Tight-fitting doors and windows: As termites eat through timber around window frames and door frames, the wood can warp, making them harder to open or close.
- Sagging or uneven floors: Damage to the subfloor can cause sections to feel soft or bounce slightly underfoot.
- Frass (termite droppings): Some species leave behind small, pellet-like termite droppings near exit holes in wood. They look like sawdust or coffee grounds and are easy to miss.
If you’re noticing any of these, it’s worth knowing when to book a termite inspection before the situation develops further.

Mud Tubes: A Telltale Sign You Shouldn’t Ignore
Of all the termite infestation signs, mud tubes are one of the most reliable indicators that subterranean termites are active on your property. These pencil-width tunnels are built from soil, termite droppings, and saliva, and they serve as a protected highway between the termite nest and the timber the colony is feeding on.
A termite mud tube can appear on:
- The exterior or interior of the foundation walls
- Along skirting boards and wall cavities
- On concrete stumps or timber posts beneath the home
- Running up from soil level to above-ground wooden structures
Mud tubes don’t always mean there’s an active infestation, as termites sometimes abandon old ones, but their presence is never something to dismiss. If you break open a mud tube and see live insects moving inside, the colony is still active and feeding.
The critical thing here is to get rid of termites before they spread to other parts of the structure. The longer a termite colony has uninterrupted access to a food source, the more extensive the damage becomes.

Termite Damage vs Water Damage: Key Differences
One of the most common mistakes homeowners make is misidentifying termite activity as water damage. It’s an understandable mix-up because both can produce similar-looking surface symptoms, but there are key differences worth knowing.
Water damage typically causes:
- Staining or discolouration on walls and ceilings (water stains that follow gravity)
- Wood rot that is soft, spongy, and crumbles easily
- Peeling paint with a damp feel to the touch
- Swelling or warping near plumbing lines or roof penetrations
Termite damage typically causes:
- A honeycomb pattern inside timber where channels run along the grain
- Wood that appears intact on the surface but collapses when pressure is applied
- Bubbling paint without any moisture present
- Damage that follows the timber grain in a structured, almost surgical pattern
The real danger is assuming it’s just a bit of wood rot when termites are actually behind it. If you can’t confidently identify the source, a professional inspection is the safest next step.

Where Termites Hide and the Damage They Leave Behind
Termites are experts at staying out of sight. They operate hidden beneath floors, inside walls, behind cladding, and deep within structural elements of your home. This is precisely why considerable damage can accumulate before anything looks wrong from the outside.
Some of the most vulnerable spots in a Perth home include:
- Door frames and window frames: Timber surrounds are a common entry point, particularly where wood meets the ground or masonry.
- Skirting boards: One of the first places termites travel once they’re inside a wall cavity.
- Roof void timbers: Rafters, battens, and ceiling joists are high-risk areas that are rarely inspected by homeowners.
- Subfloor framing: Bearers and joists sitting close to soil are highly accessible for subterranean species.
- Fence posts and decking: Garden structures that have direct ground contact are a prime target and can act as a bridge into the home.
When you identify termite damage in any of these areas, you’re often looking at just the visible portion of a much larger problem. The damage hidden inside walls or beneath flooring can be far more severe by the time it’s spotted.
To prevent termite damage to your home, regular checks of these high-risk areas are one of the most effective things you can do between formal inspections.
Why Early Detection Matters More Than You Think
A fully established termite colony can contain hundreds of thousands of individual insects, all working continuously, 24 hours a day. These insects don’t sleep, and they don’t stop eating. That’s why early signs of termite activity should never be put off.
Left untreated, a termite infestation can cause severe structural damage to a home within 12 to 18 months of becoming established. We’re not talking about cosmetic issues here. Severe structural damage can mean compromised load-bearing walls, failed floor systems, and costly repairs running into tens of thousands of dollars.
The structural integrity of a property can be genuinely at risk when termites have had unrestricted access for a prolonged period. Some homeowners are reluctant to act on early signs because they’re unsure whether what they’re seeing is actually a termite problem. This is exactly the wrong approach. If you suspect termite activity, the cost of investigation is minimal compared to what you could face in repairs if you wait.
Avoid disturbing suspected mud tubes or damaged timber before a professional has assessed the situation. Disturbing the area can cause termites to relocate to another part of the structure, making them harder to treat and potentially spreading the damage.

What Happens During a Professional Termite Inspection
A professional termite inspection is a thorough, systematic assessment of your entire property, not just a quick look around. Our experienced technicians at Bug Busters use thermal imaging, moisture meters, and termite detection devices to locate termite activity that isn’t visible to the naked eye.
During the inspection, we assess:
- All accessible timber in the subfloor, roof void, and interior
- The perimeter of the building and any external structures
- High-moisture areas that create ideal conditions for termite activity
- Evidence of past or current infestations, including mud tubes, frass, and damaged wood
At the end of the process, you’ll receive a detailed report outlining exactly what was found, where the risk areas are, and what treatment options are available. Whether the result is a termite barrier, baiting system, or direct chemical treatment, we tailor a treatment plan based on the specific conditions of your property.
DIY treatment is rarely effective for established infestations. Without the right equipment and knowledge, a DIY approach typically fails to reach the termite nest, which means the colony survives and the problem returns. The reliable termite management professionals at Bug Busters give you a solution that actually addresses the source.
