These termites belong to the Termitidae family, the largest termite family in the world. Within this family, they’re part of the Nasutitermitinae subfamily. Let’s break down the most notable Australian species in this extended family.
If you notice any of these signs, it’s worth getting a professional inspection to avoid further damage.

In the Melbourne region and other areas of southern Australia, they occur in both natural and urbanised landscapes, particularly where there is an abundant source of fallen timber or buried wood waste. Their foraging galleries may run from the mound through the soil to an adjacent building, fence or timber landscaping, allowing them to feed without being in the open.
Although they do not rely on decayed heartwood as do some other species, they favour timber in ground contact and will attack both hardwood and softwood if the conditions are right. The distance they can travel underground, along with their nesting behaviour, means that infestations can take place where the mound is several metres from a building.
Nasutitermes exitiosus is found throughout much of southern Australia, including suburban and urban areas. They are commonly found nesting in open woodland and grassland and also in suburban gardens in soil mounds. The termite is also frequently found in garden beds, fence posts, retaining walls, and under lawns.
N. exitiosus, unlike some mound-building species, does not need a cover of undergrowth or vegetation to survive, and they can manage in quite open areas so a property with few trees doesn’t necessarily mean you are safe.
Trees and properties surrounded by other structures may mask the presence of mounds in urban areas as they can be hidden in the landscape or behind sheds, garages, garden sheds and other garden features.
Nasutitermes exitiosus are not as aggressive as the Coptotermes frenchi termite but can still be very destructive to timber. They have been known to attack softwoods and occasionally any timber that is wet or weathered such as fences, decks, pergolas and occasionally house stumps and subfloor timbers. If left untreated feeding by these termites can weaken the structural integrity of affected timber and lead to expensive repair bills.
Termite mounds can sometimes be several metres away from the structure being attacked, so it may not be apparent there is a colony present that is causing the damage. Inspection is important, especially for properties with untreated timber or that are in areas where N. exitiosus has been previously identified.

Nasutitermes exitiosus primarily forms large soil mounds in gardens and lawns or in open woodland, however, they may forage into timbers in contact with the ground such as fence posts, decking, retaining walls and garden sheds. Continued feeding in these timbers can weaken structural timbers with the potential for collapse. This can lead to potential safety concerns if the affected timber is untreated and supporting weight.
Their activity also traps moisture in the timbers which is a perfect environment for mould and fungal growth. Mould spores can have a detrimental effect on people who have respiratory issues such as asthma, allergic reactions, and other long-term lung conditions. Children, the elderly and those with a compromised immune system are most at risk.
N. exitiosus are not commonly known to cause significant infestations within indoor timbers, however, moving or disturbing infested mounds and timber can release fine soil and wood particles that may contribute to localised dust and minor air quality concerns.
The first step in the early detection of Nasutitermes exitiosus is a thorough inspection of the property, especially open areas where the soil mounds are likely to be found. We also inspect neighbouring timber structures, garden beds and fence posts for mud tunnels, pellets and damaged timber.
After the nest is found we use our preferred treatment method of direct nest elimination, where the mound is dismantled and removed safely. In some cases, we may apply a chemical soil barrier around the site to prevent any remaining termites from re-establishing the colony or spreading to other structures.
We can install termite monitors near these high-risk areas to help detect any future termite activity. By combining our field experience, reliable treatment methods and ongoing monitoring, we protect your property from Nasutitermes exitiosus now and in the future.

Although not typically regarded as an overly destructive species, the adaptability and wide distribution of this species means that they commonly require curative treatments from termite experts. In addition, the fact that Nasutitermes responds poorly to modern bait methods, the range of treatment methods available to termite managers is reduced, making even a small infestation challenging to control.
Our licensed technicians at Specialist Termite Control understand the habits and hiding spots of Nasutitermes exitiosus. With decades of hands-on experience, we know how to locate nests, monitor activity, and apply the right treatments to keep your property safe.

Nasutitermes exitiosus is a type of mound-building termite found in southern Australia. They nest in soil and forage for timber that is in contact with the ground. Nasutitermes exitiosus are less aggressive than some subterranean species, but they can still damage fences, decking, and garden furniture if left unchecked.
Nasutitermes exitiosus is widespread across southern Australia. They are found in Victoria, South Australia, and parts of New South Wales. They nest in open areas, grasslands, gardens, and parks. Colonies can build dome-shaped soil mounds up to several metres from their nest, which gives them access to timber structures.
Workers are pale and soft-bodied, and soldiers have the characteristic pointed snout (nasus) of this species. They use their strong mandibles to defend the colony. The other signs of an infestation include dome-shaped soil mounds in your yard, mud tubes from the soil to timber, or damaged wood that sounds hollow when tapped. Swarming winged termites (alates) may appear in late spring or early summer, leaving behind discarded wings around windows or doors.
The good news is that Nasutitermes exitiosus does not bite or sting. So, they are not directly harmful to people. However, their activity can create conditions for mould and fungal growth, leading to respiratory issues and allergic reactions. This is especially true for children, the elderly, or those with compromised immune systems. Handling the affected timber or soil can also cause fine dust or particles to irritate your skin or airways.
