How to Spot a Termite Infestation (and What to Do)

How to spot a termite infestation. Termites cause hundreds of millions of dollars of property damage across Australia every year, feasting on timber structures while racking up serious repair bills for home and business owners.

While the termites themselves can be hard to spot, they often leave behind a number of telltale signs to help you spot their presence. Should you spot any of the following, we suggest you seek expert help from professional pest control specialists who will provide a long-lasting, effective treatment.

Six key signs of a termite infestation 

Swarmers and discarded wings

Flying termites (aka “swarmers”) are usually the first signs of an infestation, emerging from the nest in large groups either to find a suitable mate or a larger home. Some termite species swarm at night and are attracted to light, while others swarm in the day (particularly after heavy rainfall).

Once swarmers land in their desired destination, they twist off their wings as they’re no longer needed. The discarded wings are usually found near common home-access points, for example, next to windows or doors, or around your property’s foundation.

Mud tunnels 

Subterranean termites create mud tubes as they travel through soil to get to food sources, offering protection and humidity to help the termites thrive. Commonly found near building foundations, the pencil-sized mud tubes are made from a combination of soil and termite droppings and are easy to spot with the naked eye.

You can help avoid attracting termites by eliminating moisture-rich environments, and storing any firewood, mulch, or wood chips away from your home.

Cracked, hollowed, or blistered wood 

Termites consume wood from the inside out, leaving behind just a thin veneer of timber. You can spot signs of termite damage through blistered or cracked furniture, skirting boards, floorboards, or timber structural supports—or by tapping on the affected areas to check for a hollow sound. 

You may also notice termites through unexplained cracks in the walls—evidence of these timber-hungry pests consuming the cellulose within your walls.


Termites are sensitive to noise and vibrations, using several organs at the base of their antennae and on the tibia (one of the segments of the leg) to communicate between the colony. If you can hear a quiet, clicking sound coming from the walls, it’s likely soldier termites banging their heads against the wood, signalling danger to the rest of the colony.

Frass (termite droppings) 

Often confused with sawdust, frass is the wood-coloured droppings from dry wood termites. Unlike subterranean termites who use their droppings to create mud tubes, dry wood termites push it out of small holes near the entrances to their nest, leaving behind black marks and a dark powdery substance around any infested areas.

Hard to open windows or doors 

The final sign of a termite infestation often gets mistaken for damp and hot weather: stiff windows and warped doors. When eating and tunneling through doors and window frames, termites produce moisture, causing the wood to warp, and therefore making them tough to open.

What to do if you find termites 

How to spot a termite infestation, don’t panic. Avoid the temptation to try and treat them yourself as the termites may feel the disruption and relocate to another spot in your house. Instead, seal up their workings with tape (to prevent light access) and then seek professional help from a termite control specialist.
