This is why we use Kordon Termite Barrier in every Unicus Home…


The Kordon Termite Barrier is a unique Australian designed and made building product that functions as both a termite and moisture barrier.Kordon has been extensively tested over 2 decades by Bayer Environmental Science, the CSIRO, State Forestry Departments and State Building Authorities. In all evaluation work carried out by Bayer Kordon has achieved 100% performance as an effective physical barrier to termites.

The Kordon Termite Barrier is backed by a $250,000 Lifetime Timber Replacement Warranty.

Termites are one of Australia’s most destructive natural forces. They cause over $900m damage to Australian homes annually. 

How does Kordon work?

Kordon is a flexible laminate that is installed in the building during the construction process to prevent concealed access by subterranean termites.  Kordon contains deltamethrin which is highly repellent to termites.

Subterranean termites (termites) are social insects that live in a colony like bees and ants. Typically they form a nest in the soil or near ground level in a stump or trunk of a tree. They eat cellulose which is found in timber and timber products such as paper. Attack by termites originates from the nest. Foraging termites will seek cellulose up to 50 m or more from their nest. Wood or timber lying or buried is reached by underground tunnels built by the termite workers. Timber above ground may be reached inside the timber or via mud walled tubes plastered to exposed surfaces. These tubes are built by the termites to shelter them from the light and maintain humidity. There are more than 350 species in Australia and about 30 are classified as economically important – that is they attack timber in buildings.

As well as eating timber, termites can damage non-cellulose materials such as soft concrete, soft metal and plastic, building sealants and foam insulation.

Cracks in concrete and the gap around pipes penetrating through the concrete slab offer easy access to termites. Kordon is installed where termites may attempt to gain access to the timber in a building. The deltamethrin in Kordon is highly repellent to termites and they will avoid close contact with it. Where Kordon is installed the termites will seek cellulose elsewhere or seek to go around the Kordon. When seeking to go around the Kordon the termites will build their mud tubes which will be detected during an inspection by a suitably qualified Timber Pest Inspector.  Steps can then be taken to eliminate the termite colony before significant damage can be done. When termites get concealed access, such as when Kordon is not installed, access is gained for a long period resulting in significant and expensive damage


Some Information on Termites

Termites are small, pale white to brownish in colour, insects that feed on wood.

Termites are social insects. This means they have different looking individuals, called castes, to carry out the tasks or jobs of the colony. These tasks include reproduction done by the king and queen, defence conducted by soldiers, and workers who conduct most the activities of the colony; finding food, building nests, and taking care of the eggs and young termites.

Termites are commonly referred to as white ants purely by the colour of their bodies and they are similar
looking to an ant.

Termites eat cellulose, the basic building block of wood.

There are many variables involved in how much damage termites can cause to a home.

Termites can travel 100 metres or more to access a food source such as your home. It is recommended by Australian Standards to have inspections at least annually and treatments if needed once the inspection is done.

When a termite inspection is conducted you will be supplied with a report that lists recommendations to reduce the risk of termite attack. These could be poor drainage, timbers in contact with the ground, leaks in plumbing etc. These are called conducive conditions and should be rectified.

Most homeowners will rarely see termites. These are secretive, cryptic insects that hide deep in wood or soil. However, during the spring , termite colonies produce alates – winged reproductives. These alates are new kings and queens. Their job is to start new colonies.

Sometimes you may notice their shelter tubes. These tubes are about the diameter of a pencil (sometime larger) and are made of soil. If you break one open, you may see a live termite inside!

Where possible, treatment should be directed towards eradication of the termite colony from which the infestation is originating.

Where the Nest is Found destruction using physical / chemical means should be undertaken.

Where the Nest is Not Found but active termite workings are found, it is possible to eradicate the attacking colony with the use of termite baiting systems remote from the nest.

Once the colony is eliminated a monitoring system or a chemical soil barrier is recommended.

The best treatment for your home will depend on many factors that are unique to your home, your termite problem and your personal preferences.


The Australian Standards recommend that all homes should be inspected at least once per year. ..
