Signs of Termites in Your House: Key Indicators to Notice

Common indicators of termite infestation in a home include mud tubes on walls or piers, timber that sounds hollow when tapped, doors and windows that suddenly stick, bubbling paint, discarded wings, and clicking or rustling noises emanating from within the walls.

These signs can often go unnoticed. Termites consume timber from the inside, meaning a skirting board or door frame may appear undamaged while being compromised internally. Here’s what to observe and listen for.

How Can You Identify Signs of Termite Infestation in Your Home?

Termites tend to remain concealed, leaving behind telltale signs. A single indicator does not confirm an infestation. For example, doors may stick in humid conditions, and bubbling paint can indicate simple dampness. the City of Gold Coast’s termite guide warns that termites can inflict extensive damage before detection, making regular inspections crucial for early identification of activity. If you notice any signs, avoid disturbing them and seek professional assessment.

Eight Key Indicators of Termites to Observe and Listen For

#1 Identifying Termite Mud Tubes on Walls, Piers, and Stumps

Mud tubes, also referred to as shelter tubes, are slender trails of dried mud constructed by termites. They blend soil, timber particles, and saliva, allowing termites to traverse between their nest and their food source while remaining protected from air and light.

Be vigilant for these tubes ascending external walls, foundations, brickwork, piers, stumps, and fence posts, as well as crossing concrete paths. Many people misinterpret them as dirt splashed up by rain. Victoria’s Department of Health observes that properly installed metal ant caps on subfloor stumps prompt termites to create visible mud tubes over the cap, making the tops of the stumps prime locations for inspection. If you discover a mud tube, refrain from breaking or removing it.

#2 Listening for Termite Clicking or Rustling Sounds in the Walls

Termites can be quite noisy. The City of Gold Coast highlights clicking or rustling sounds within walls or timber as a frequent indicator of termite activity.

Certain termite species communicate through vibrations. Research conducted by the University of Technology Sydney in 2018 on Sebastian Oberst’s studies indicates that Coptotermes acinaciformis, a significant pest, employs vibrations to assess food, monitor competitors and predators, and alert their colony. A 2017 study by Joseph Lai, Sebastian Oberst, and Theodore Evans further notes that soldier termites emit vibratory alarm signals to warn workers. This research pertains to vibrations transmitted through timber, though it does not specify which vibrations may be audible through walls.

If you suspect you’ve heard clicking or rustling within a wall, take note of the location and avoid disturbing it. Termites are not always audible, which is why our termite inspections incorporate audible testing using a donga tool, along with thermal and moisture imaging, and Termatrac radar to detect activity beneath the surface.

#3 Observing Timber That Feels Hollow or Soft

Skirting boards, door frames, and floorboards that sound hollow when tapped are common indicators of termite presence. The Gold Coast guide highlights timber that appears soft or shows signs of damage.

#4 Recognising Sticky Doors and Windows as Potential Termite Signs

Doors and windows that suddenly become difficult to open or close could signal a termite issue. Moisture can also cause frames to swell, making it tempting to attribute the problem to rain. Termites consume the internal structure of door frames and window sills, possibly causing distortion as they hollow out the frame. If you notice doors or windows sticking, particularly in multiple areas of your home, it’s wise to get them inspected.

#5 Identifying Bubbling Paint as a Possible Sign of Termite Activity

Bubbling or peeling paint that resembles water damage ranks among the common indicators of termite presence according to the Gold Coast council. Termites require moisture in addition to timber. The Australian Museum clarifies that subterranean termites typically become problematic in structures with a consistent water source, such as leaking pipes or roofs.

#6 Spotting Termite Holes in Ceilings or Walls

Termites may create small openings in plaster, gyprock, or paint as they consume timber. This results in tiny holes, often accompanied by fine, sandy debris. If you observe holes in a ceiling or wall without an apparent cause, take them seriously, as they may indicate prolonged termite activity within the structure.

#7 Finding Discarded Termite Wings in Proximity to Windows, Doors, or Lights

Flying termites typically leave their nests in warm, humid conditions to establish new colonies, shedding their wings upon landing, as noted by the Australian Museum. Victoria’s Department of Health indicates that discarded wings are a reliable sign of termite presence.

A swarm near your property doesn’t necessarily indicate that your home is infested, as they can originate from nests in gardens, neighbouring yards, or nearby trees. Nonetheless, it serves as a valid reason to schedule an inspection and determine the location of the colony.

#8 Observing Live Termites in Timber or Mud Tubes

Occasionally, you may spot termites themselves within timber, walls, furniture, or broken mud tubes. The Australian Museum describes termites as having pale brown to white bodies with darker heads, bead-like antennae, and a lack of a narrow waist, distinguishing them from ants. Soldiers possess larger, darker heads, and Victoria’s Department of Health notes that Coptotermes soldiers release a white, rubbery, glue-like substance when disturbed. If you encounter live termites, refrain from disturbing them.

What Does Termite Damage Typically Look Like?

Termite damage is often concealed behind seemingly normal surfaces. Since termites consume timber from the inside, a wall that appears intact may actually be hollow behind the paint.

Termite damage can resemble wood rot, making it challenging to distinguish between the two. A timber pest inspection conducted according to the Australian Standard AS 4349.3 encompasses subterranean and dampwood termites, borers, and wood decay fungi (rot), providing clarity on the specific issue at hand. Our pre-purchase termite inspection page details what this standard includes.

Where Should You Inspect for Termite Signs in a Sydney Home?

Our termite protection guide identifies much of Sydney, including the Hills District, North Shore, Western Sydney, and coastal suburbs, as high-risk zones for termite activity. Key areas to inspect include:

• The roof void and associated roof timbers.
• The subfloor, particularly around stumps and piers.
• Skirting boards, architraves, and door and window frames, especially in bathrooms, laundries, and other moisture-prone areas.
• Timber fences, retaining walls, and tree stumps.
• Garden beds and mulch adjacent to the home, particularly where they touch the slab edge.
• Wooden furniture and stored timber.

Gum trees located near the house should also be included in your inspection. Victoria’s Department of Health notes that Coptotermes termites prefer nesting in trees, particularly eucalypts, as well as in stumps, beneath concrete floors, and within wall cavities.

What Actions Should You Take If You Discover Signs of Termites?

Avoid disturbing the area. Do not spray, break the mud tubes, or seal openings from which flying termites emerge. Disturbing an active termite lead can cause the termites to relocate, making them even more challenging to locate and treat.

Take a photo, note the location of the sign, and contact us at 0410 244 244. Share what you observed and where, and we will organise a termite inspection. If termites are confirmed, our termite treatment page outlines the methods we employ to eradicate the colony and safeguard your home.

How Does So Pest Off Detect Hidden Termites?

Since termites operate within timber, a So Pest Off termite inspection employs a combination of four detection methods:

• A visual assessment to identify signs of termite activity and damage.
• Audible testing with a donga tool to locate hollow spots in timber.
• Thermal and moisture imaging. A thermal imaging camera detects temperature variations created by an active nest or moisture pocket behind a surface, while a moisture meter verifies if a wall is retaining unwarranted water.
• Termatrac radar, which detects live termite movement behind plasterboard, timber, brick, and masonry without the need for drilling.

Termatrac, designed in Australia, incorporates radar, thermal, moisture, and temperature sensors. When termites are present in a home, our technician employs Termatrac termite tracking to trace them through walls and frames to their entry points and nest locations, eliminating the need to dismantle walls, skirting, and floorboards to locate them. This method is also useful when live termites are found during renovations, allowing us to determine the extent of activity within the walls before further work is undertaken.

The radar detects movement, necessitating a quiet and empty environment during tracking. It does not identify previous damage where termites have vacated, which is why tracking is conducted following a comprehensive inspection rather than as a substitute for it.

You will receive a written report complete with photographs, detailing what was inspected, findings, inaccessible areas, and our recommendations. We recommend scheduling a termite inspection annually for a Sydney home, with increased frequency if termites have been previously identified or if the property contains abundant timber and moisture.

Final Thoughts on Identifying Signs of Termites

Observing mud tubes, hearing clicking or rustling in walls, detecting hollow timber, experiencing sticking doors, noticing bubbling paint, discovering tiny holes, finding discarded wings, and spotting live termites are all compelling reasons to arrange a termite inspection. Termites can inflict considerable damage before they are detected; therefore, it is essential to leave any signs undisturbed and have them professionally assessed.

Frequently Asked Questions About Termite Signs

Is It Possible to Hear Termites in the Walls?

Occasionally. Clicking or rustling noises within walls or timber are listed as common signs of termite activity by the City of Gold Coast. the absence of sound does not guarantee that the house is free from termites, making listening an insufficient substitute for a thorough termite inspection.

What Do Termite Mud Tubes Look Like?

They appear as thin trails of dried mud ascending walls, foundations, piers, stumps, or fence posts, composed of soil, timber particles, and termite saliva. Do not disturb them; instead, arrange for an inspection.

Do Termites Produce Droppings?

Some species do. The City of Gold Coast notes that small, pellet-like droppings, known as frass, often indicate the presence of drywood termites. The WoodSolutions durability guide reports that drywood termites are primarily found in Cooktown, Queensland, and further north, while subterranean termites are the main concern in Sydney, emerging from the soil.

How Can I Differentiate Between Termites and Ants?

Termites lack a narrow waist, exhibit bead-like antennae, and possess pale brown to white bodies, according to the Australian Museum. Although often referred to as white ants, they belong to a distinct insect classification separate from true ants.

How Frequently Should I Schedule a Termite Inspection in Sydney?

We recommend conducting a termite inspection annually for homes in Sydney. Increased frequency is advisable if termites have been previously identified or if the property has significant timber and moisture.
