Termite activity is not always easy to spot.
A Perth home can look well maintained from the street while evidence of termite activity or timber damage exists in less obvious areas. In some cases, the first clue is not seeing live termites at all. It may be a mud-like trail, damaged timber, discarded wings or an unexplained change around a door frame or skirting board.
For homeowners, the important thing is knowing which signs deserve further investigation without assuming that every crack, sticking door or patch of damaged timber means termites.
Here are some of the termite warning signs Perth property owners should know.
Why Termite Warning Signs Can Be Easy to Miss
Termites can access and affect timber in areas that are concealed, difficult to reach or rarely checked during normal home maintenance.
That is why looking for visible insects alone is not enough.
A professional timber-pest inspection considers evidence of current activity, previous damage and conditions that may make future infestation more likely. Relevant areas can include accessible roof and floor timbers, external structures and other timber elements around a property.
If you want a detailed explanation of the professional inspection process, see our Termite Inspection Checklist: What Engineers Look For.
1. Termite Mud Leads or Workings
Mud-like termite workings are one of the more recognisable warning signs.
Subterranean termites can construct protected pathways between the ground and a timber food source. These may appear around accessible foundation areas, masonry, service penetrations, subfloor components or other building junctions.
They may be narrow and easy to overlook, particularly behind stored items or around less frequently inspected parts of the property.
If you discover suspected termite workings, avoid unnecessarily disturbing them before they can be professionally assessed.
2. Timber That Sounds Hollow or Feels Weakened
Timber can sometimes retain a relatively normal-looking external surface even when deterioration exists internally.
Skirting boards, door frames, window frames and other accessible timber elements that appear unusually fragile, damaged or hollow may warrant further investigation.
However, hollow-sounding timber is not proof of active termites by itself. Timber deterioration can have different causes, so the condition needs to be assessed in context.
3. Unexplained Timber Damage
Common signs of termites in Perth homes can include timber damage, hollow areas, and hidden infestations that require professional inspection.[/caption]
Pay attention to timber that appears:
- Soft or unusually fragile
- Cracked or deteriorated
- Hollowed internally
- Damaged around edges or joints
- Different from surrounding timber
The location of the damage matters.
Damage to decorative timber is different from deterioration affecting load-bearing components such as joists, bearers, rafters or structural framing.
Where significant timber damage is identified, further assessment may be required to determine both the pest issue and the condition of affected building elements.
4. Discarded Wings Around the Property
Small piles of discarded insect wings around windows, doors or other areas can warrant closer investigation.
Winged reproductive termites can leave an established colony and later shed their wings. However, homeowners should avoid identifying an insect species from wings alone because other insects may appear similar.
If unexplained wings repeatedly appear around your property, photograph the area and arrange professional identification rather than relying on guesswork.
5. Changes Around Skirting Boards and Door Frames
A skirting board that suddenly becomes fragile or a timber frame showing unexplained deterioration should not automatically be dismissed as normal ageing.
Possible warning signs include:
- Damaged skirting boards
- Soft timber
- Unusual surface deterioration
- Localised swelling or distortion
- Timber that breaks more easily than expected
These symptoms can also have non-termite causes, including moisture and general timber deterioration.
A professional inspection helps establish what is actually present rather than assuming the cause from appearance alone.
6. Moisture Around Timber Areas
Moisture does not automatically mean termites are present.
However, moisture and drainage conditions are relevant considerations during a timber-pest inspection because damp areas and deteriorating timber can affect the condition of a property and may contribute to environments that deserve closer assessment.
Pay particular attention to unexplained moisture around:
- Bathrooms and laundries
- External walls
- Plumbing penetrations
- Subfloor areas
- Downpipes and drainage points
- Timber adjoining damp areas
The objective is not simply to find a damp patch and label it a termite problem. The source of moisture and the condition of nearby accessible timber need to be considered together.
7. Evidence in the Roof Space or Subfloor
Some important areas of a property are rarely seen by the homeowner.
Where safely accessible, roof spaces and subfloors can contain timber elements that deserve assessment during a timber-pest inspection.
An inspector may look for evidence such as termite workings, timber deterioration, previous damage, moisture-related conditions and other relevant observations.
Access matters. Insulation, stored belongings, restricted openings, low clearances and other obstructions can prevent complete inspection of some areas.
A good inspection report should explain significant access limitations rather than implying that concealed areas have been fully assessed.
8. Previous Termite Damage or Treatment Evidence
Previous termite activity remains relevant even when no current activity is identified.
If a property has old timber damage, evidence of previous treatment or an existing termite-management system, buyers and owners should understand:
- Where previous activity occurred
- Whether visible damage remains
- Whether repairs are evident
- What areas were inaccessible
- Whether a management system is present
- What future inspection or maintenance has been recommended
A statement that no current termite activity was identified should not be interpreted as a lifetime guarantee.
Can Termites Be Present Without Obvious Signs?
Yes. Some termite activity can occur in concealed or difficult-to-access areas, which means a homeowner may not see obvious surface evidence.
This is one reason a professional inspection involves more than searching for visible termites.
An inspection may consider accessible evidence of current activity, previous timber-pest damage and conditions around the property that deserve attention.
It is equally important to understand the limitation: a non-invasive inspection cannot guarantee the condition of every concealed building cavity.
What Should You Do If You Suspect Termites?
If you find suspicious timber damage, termite workings or other possible evidence, avoid jumping straight to a conclusion.
A sensible sequence is:
- Avoid unnecessarily disturbing the suspected activity.
- Record where the evidence was found.
- Arrange a professional termite or timber-pest inspection.
- Read the entire inspection report, including access limitations.
- If treatment is recommended, engage an appropriately licensed pest-management professional.
- If significant structural timber damage is suspected, obtain appropriate building or engineering assessment.
Inspection and treatment are different services. An inspection establishes and documents the observed conditions; treatment deals with identified termite activity or termite-management requirements.
What About Termites When Buying a Perth Home?
Termite considerations become particularly important when purchasing an established property.
Western Australian Consumer Protection recommends that home buyers obtain a timber-pest inspection report. A report can provide information about current infestation, previous damage, areas that may be susceptible to future infestation and recommendations for future inspection or maintenance.
If you are buying, consider combining timber-pest assessment with a pre-purchase building inspection in Perth.
This allows building defects and timber-pest concerns to be considered as part of your broader due diligence rather than looking at the property from only one perspective.
For a general explanation of the combined service, read What Is a Building and Pest Inspection?.
How Often Should Perth Homes Be Inspected for Termites?
There is no single inspection interval that should be blindly applied to every property.
Appropriate timing can depend on factors such as:
- Previous termite history
- Existing termite-management systems
- Property construction
- Access restrictions
- Moisture and drainage conditions
- Timber-to-ground contact
- Changes made around the property
- Recommendations contained in previous reports

The important point is to follow property-specific recommendations rather than waiting for obvious damage to appear.
Termite Signs vs Structural Damage
Finding evidence of termites and identifying structural damage are not the same thing.
Termite activity is primarily a timber-pest issue. It becomes a building or structural concern when damage affects important building elements such as floor joists, bearers, rafters, beams, posts or structural framing.
This distinction is particularly important for buyers.
A report should help establish what has actually been observed rather than jumping from “possible termite evidence” to “major structural problem”.
You can learn more about this distinction in our guide to structural faults in Perth homes.
Frequently Asked Questions About Termite Signs in Perth
What is one of the most obvious signs of termites?
Mud-like termite workings and visibly damaged timber can be important warning signs. However, not every property with termite activity will show obvious surface evidence.
Does hollow-sounding timber always mean termites?
No. Hollow, weak or deteriorated timber can have different causes. It should be assessed alongside other evidence rather than being treated as proof of active termites.
Should I break open a termite mud tube?
Avoid unnecessarily disturbing suspected termite workings before professional assessment. Document the location and arrange an inspection.
Are moisture problems a sign of termites?
Moisture does not prove that termites are present. However, moisture and drainage conditions can be relevant during a timber-pest assessment and may warrant closer investigation of nearby timber.
Can a newly built home get termites?
A newer property should not automatically be considered immune from future termite activity. Existing termite-management measures, property conditions and ongoing inspection and maintenance recommendations still matter.
Does a termite inspection include treatment?
Not necessarily. Inspection and treatment are separate services. StructSure focuses on inspection and reporting; where treatment is required, an appropriately licensed pest-management professional should be engaged.
Can thermal imaging see termites inside walls?
Thermal imaging does not simply see termites through walls. It can identify certain surface temperature anomalies that may justify further investigation when interpreted alongside other inspection evidence.
Should I get a termite inspection before buying a Perth property?
A timber-pest inspection can provide valuable information about current activity, previous damage, relevant risk conditions and inspection limitations before purchase. It can also be combined with a broader pre-purchase building inspection.
