Your house can be destroyed by termites, especially when they find their way into the walls, leading to a potential termite attack. Early detection of the signs can help prevent costly repairs. Seven common indicators of termites in walls include hollow or papery sounds, clicking or tapping noises, the presence of mud tubes or tunnels, peeling paint or bubbling wallpaper, pinholes in drywall and plaster, termite droppings, and warped walls.
7 Signs of Termites in Walls and What You Need to Do Next
Common Signs of Termites in Walls
Hollow or Papery-Sounding Walls
One common indicator of termite damage is hollow or papery-sounding walls. Termites hollow out the wood inside your walls and build tunnels, leaving only the outer shell intact. When you tap or knock on the surface, this weakening of the wood produces a distinct hollow sound. The more widespread the damage, the more noticeable the sound will be.
If you believe your walls sound hollow, you should investigate further, as this may point to a major infestation. This kind of damage can spread rapidly, so it’s crucial to have a comprehensive inspection and treatment by a pest control expert to eliminate termites and prevent further harm to your home’s structure.
Clicking or Tapping Noises
Clicking or tapping noises coming from your walls can be a clear sign of termite activity. These sounds are typically caused by worker termites chewing through timber or communicating with each other. Subterranean termites, in particular, create such noises while boring through wooden structures.
Although subtle, these sounds can be heard if you pay close attention to areas with active termites. The clicking sound occurs when termites bang their heads or mandibles against the wood or each other. If you hear such noises, inspect your home for signs of infestation. Early detection and professional termite control will help prevent further damage and costly repairs.
Visible Mud Tubes or Tunnels
Visible mud tunnels or tubes are a sure sign of termite infestation. These structures, built by subterranean termites, allow them to travel from their nest to their food source—namely, the timber in your walls. Typically found on the external foundation of your home or even within the walls, these tubes protect termites from the elements.
Made from a mix of soil, timber, and saliva, the tubes are often brown or grey in colour. If you discover mud tunnels in or around your home, you should act quickly. Contact a licensed pest control company for a professional termite inspection before the infestation causes serious structural damage.
Peeling Paint or Bubbling Wallpaper
Peeling paint or bubbling wallpaper can also indicate termite activity behind your walls. As termites feed on the wooden framework behind the wall surface, they release moisture that can seep through plaster or drywall. This excess moisture causes paint to bubble or wallpaper to peel.
These signs are commonly found in areas where termites have been active for a prolonged period. If you notice unexplained peeling or bubbling, it could point to a termite problem. Immediate treatment by a termite control specialist can prevent further structural damage and preserve your home’s integrity.
Tiny Pinholes in Drywall or Plaster
As termites gnaw through timber inside your walls, they can create small holes in the drywall or plaster. These pinholes may be hard to notice at first, but they’re a sign that termites have been feeding within your walls. Left untreated, the damage could become extensive.
If you spot pinholes, conduct a thorough inspection of your home to assess the extent of the infestation. Early identification allows for targeted treatment before the problem escalates.
Flying termites are a clear sign that a termite colony is trying to establish new colonies. When they swarm, they shed their wings, which can be found in small piles near window sills or skirting boards. These discarded wings are a common sign of termite activity. If you notice termite wings around your home, it’s important to check for termite nests and other signs of an infestation to prevent further damage.
Termite Droppings
Termite droppings, or frass, are a clear indication of termite activity. These small, dark, pellet-like droppings are usually found near termite entry points or feeding areas. As termites consume timber, they produce waste that accumulates in and around their tunnels.
While termite frass may resemble sawdust, it’s darker, more uniform in shape, and contains wood particles. If you discover these droppings, you need to act immediately. Contact a professional pest control company to inspect and treat your property before the infestation worsens.
Warped Walls
Warped walls are often a visible sign of severe termite damage. As termites consume cellulose-rich materials inside your walls, the timber weakens, causing the structure to twist, bend, or warp. This can lead to uneven surfaces, or windows and doors that no longer open or close properly.
Warping usually means termites have been active for some time. If you see signs of warping, you must act immediately. Contact a termite control expert to assess the damage and implement repairs to prevent further structural issues.

How to Prevent Termites from Coming Back
Seal Entry Points
Termites can gain entry through tiny cracks and gaps in your walls, doors, and windows. To keep them out, it’s essential to seal all entry points. Use caulking or weatherstripping to close visible gaps. Regularly inspect window sills, door frames, and your home’s foundation to identify and fix potential weaknesses. Blocking these access routes makes it much harder for termites to enter your property.
Remove Wood and Debris Near Your Home
Termites are attracted to timber, so keep firewood, wooden structures, and debris away from your home. Store firewood off the ground and at least 6 metres (20 feet) from your house. Remove dead branches, logs, or stumps close to your foundation. Eliminating these potential food sources reduces the risk of attracting termites and encourages them to stay away.
Install Termite Barriers
Termite barriers can help stop termites from accessing your home. There are two main types of barriers: physical barriers (like stainless steel mesh) and chemical barriers (using termiticides around the foundation). These barriers provide long-lasting protection and can be part of a wider termite management system. Consult a pest control professional to install barriers suited to your property.
Regular Inspections
Routine inspections are one of the most effective ways to prevent termites from returning. Because termites often go undetected, regular checks by a pest control expert can catch an infestation early. Inspections should be conducted annually, but more frequent checks may be necessary in high-risk areas. Early detection ensures quick action and reduces the risk of expensive repairs.
Control Moisture Levels
Termites thrive in moist environments. To deter them, maintain dry conditions around your home. Repair any roof, plumbing, or foundation leaks, and ensure proper drainage around your house. Keep plants and garden beds away from building edges and weep holes. Also, ensure your gutters are clear and functioning, as blocked gutters can lead to water buildup near the foundation. Reducing moisture is a key step in making your home less attractive to termites.
Conclusion
Termites pose a serious risk to the structural integrity of your home. Early detection of termite activity—such as hollow-sounding walls, clicking noises, mud tunnels, peeling paint, pinholes, termite droppings, and warped walls—can save you from costly repairs.
If you observe any of these signs, contact a professional termite control service immediately to inspect the property and begin treatment. Alongside treatment, preventative measures like sealing entry points, removing timber debris, installing barriers, and conducting regular inspections will help keep your home protected for the long term.
