How To Spot The Early Signs Of A Termite Infestation

Termites are one of the most destructive pests in Australia, quietly causing damage that can go unnoticed for months. When visible signs appear, the structural impact on your home or business may be extensive and costly. Catching the early warning signs of an infestation can help protect your property and save thousands in repairs.

What attracts termites and the damage you can’t see

Termites are expert hiders, feeding on timber from the inside. That’s why early-stage infestations often escape notice, especially in high-risk regions like the Shoalhaven and Illawarra, where the climate and building styles create ideal conditions for termites.

Here’s what makes your property a magnet for termite activity:

• Timber touching soil – fences, retaining walls or garden edging
• Excess moisture – leaking pipes, poor drainage or garden beds against the house
• Stored timber or mulch – especially if it’s close to external walls

Older homes in areas like Nowra, Kangaroo Valley and Shellharbour are particularly vulnerable, especially if they haven’t had a recent termite inspection.

How to spot an infestation early

Catching the signs early could be the difference between a minor treatment and major repairs. Here’s what to look out for:

• Hollow-sounding wood – Tap on skirting boards, door frames or walls. If they sound thin or papery, termites could be feeding inside.
• Mud tubes or tunnels – These pencil-sized tunnels on walls, stumps or subfloors are how termites travel and stay protected.
• Tight doors and stiff windows – Termite activity inside the frames can cause timber to warp, swell or stick.
• Discarded wings – Winged termites swarm and shed their wings near lights, windowsills or sliding doors.
• Small piles of dirt or sawdust – This could be termite frass (droppings) or a sign of tunnelling beneath woodwork.

Even one or two of these signs should prompt a closer look, because where there’s one termite, there are usually many more hidden nearby.

Why DIY checks often fall short

It’s good to stay alert, but most termite damage starts out of sight — inside wall cavities, under floors or in roof spaces. Without training or tools, it’s easy to miss early-stage infestations.

Superficial checks might pick up obvious damage, but they rarely uncover the full extent of the problem or its source. Termites are highly adaptive and can enter a property through concealed access points, including gaps in slab edges, foundation cracks or soil-covered garden beds.

A professional termite inspection goes beyond surface-level signs. Experienced technicians know how and where to investigate, using specialised equipment to detect subtle clues the untrained eye would miss. They also assess structural vulnerabilities, environmental conditions and entry points contributing to infestations.

Professionals help you catch what DIY methods can’t and give clear advice before damage spreads.

What a professional termite inspection includes

Licensed pest technicians know where to look and what to look for. A thorough termite inspection usually includes:

• Internal and external assessment, including subfloors, roof cavities, timber fences and surrounding areas.
• Specialist tools like moisture meters or thermal imaging to detect hidden nests or damp spots.
• Tailored reporting with treatment or prevention recommendations based on your property’s unique risk factors.
• Many pest companies also utilise termite detection dogs. These dogs are trained to sniff out termite activity without the need for invasive or disruptive search methods. Harry, our resident termite detection dog at Affordable Pest Control, will be more than happy to assist in determining if a termite infestation is lurking within your property.

It’s not just about what’s already there, a professional inspection helps prevent new infestations before they begin.
