Below are six warning signs that should push them from “keep an eye on it” to “book an inspection”.
What does it mean if they see mud tubes on walls or foundations?
Mud tubes are one of the clearest indicators of subterranean termites. They build pencil-width tunnels from soil to timber so they can travel while staying damp and hidden.
If they spot these tubes on brickwork, piers, slab edges, skirting boards, or inside garages and crawl spaces, it is time to call a specialist. Even old, dry tubes can mean an active nest nearby or a previous infestation that was never properly treated.
Why would timber sound hollow or papery when tapped?
Termites eat timber from the inside out, leaving a thin outer layer that can look normal. When they tap wood and it sounds hollow, dull, or slightly “papery”, internal damage is already underway.
They should not wait for a piece to collapse or for a door frame to split. A termite specialist can identify whether the hollowing is termite-related, how far it spreads, and whether structural timbers are affected.
What should they think if doors or windows suddenly stick?
Sticking doors and windows are often blamed on humidity or settling, but termite activity can also cause timber to warp. As termites tunnel, moisture patterns change and damaged wood can distort.
If the sticking appears suddenly, worsens quickly, or comes alongside other clues like fine dust or soft skirting, they should arrange an inspection. A specialist can confirm whether it is simple movement or something feeding inside frames and studs.
What are termite droppings (frass), and why is it urgent?
Drywood termites push out tiny droppings called frass. It often looks like pepper, sand, or small wood-coloured pellets collecting in little piles under kickboards, window sills, or along skirting boards.
If they find frass, they should treat it as urgent. It usually means termites are active within the timber above the pile. Cleaning it up without investigating can hide the pattern that helps locate the gallery, so it is best to leave it in place and call a specialist.
When do blistered paint, bubbling plaster, or pinholes point to termites?
Paint that blisters, small bubbles in plasterboard, or pinhole marks in timber can appear when termites tunnel close to the surface. Moisture from their activity can also make walls look slightly swollen or stained.
These signs can be confused with water leaks, which is exactly why a termite specialist is useful. They can tell the difference, check moisture levels, and inspect hidden voids without guesswork.
Why do swarms of winged insects indoors matter?
Termite alates (winged reproductives) swarm when a colony is mature and ready to expand. They are often seen near windows, lights, or spider webs, and they commonly drop wings after landing.
If they notice a sudden indoor swarm or find piles of identical, translucent wings on sills or floors, they should call a termite specialist immediately. Swarming indoors often suggests the nest is in the building, not just the garden.

When should they call even if they are not sure?
They should call a termite specialist as soon as they see any one of these signs, especially if the property is in a known termite area or has a history of infestation. It is also sensible to book an inspection when buying a home, after heavy rainfall, or if there is timber-to-ground contact, leaking plumbing, or poor subfloor ventilation.
Termites do not get better with time. A short inspection now is usually cheaper than replacing structural timber later.

FAQs (Frequently Asked Questions)
What do mud tubes on walls or foundations indicate about termites?
Mud tubes are a clear sign of subterranean termites. These pencil-width tunnels connect soil to timber, allowing termites to travel while staying damp and hidden. Spotting mud tubes on brickwork, piers, slab edges, skirting boards, garages, or crawl spaces means it’s time to call a termite specialist, as they suggest an active or previous infestation.
Why does timber sound hollow or papery when tapped in termite-infested areas?
Termites eat timber from the inside out, leaving a thin outer layer that looks normal but sounds hollow, dull, or papery when tapped. This internal damage indicates termite activity and should prompt an inspection by a specialist to assess the extent and whether structural timbers are affected before visible collapse occurs.
What causes doors or windows to suddenly stick and how is it related to termites?
Sudden sticking of doors or windows can result from timber warping due to termite tunnelling altering moisture patterns and damaging wood. If sticking worsens quickly or is accompanied by fine dust or soft skirting boards, it suggests termite activity and warrants a professional inspection to differentiate from humidity or settling issues.
What are termite droppings (frass) and why is finding them urgent?
Termite droppings, known as frass, are tiny pellets resembling pepper, sand, or wood-coloured particles found in piles under kickboards, window sills, or skirting boards. Their presence usually indicates drywood termites actively feeding within the timber above. It’s urgent to call a specialist rather than clean up immediately, as frass patterns help locate the infestation gallery.
How do blistered paint, bubbling plaster, or pinholes signal termite problems?
Blistered paint, plaster bubbles, and pinhole marks in timber often occur when termites tunnel near surfaces. Moisture from their activity can cause walls to swell or stain slightly. These signs can mimic water leaks; therefore, a termite specialist’s assessment is essential to distinguish between termite damage and moisture issues accurately.
Why are swarms of winged insects indoors a cause for concern regarding termites?
Swarms of winged termites (alates) indoors indicate that a mature colony is ready to expand and often signifies the nest is inside the building rather than just outside. They appear near windows and lights and leave piles of translucent wings after landing. Immediate contact with a termite specialist is necessary upon noticing indoor swarms.
