Installing a Termite Barrier in Sydney can protect your home from termites for many years. But unless you are aware of the differences between the barriers, you may end up installing a less effective barrier and wasting your money!
There are generally two types of termite barriers, Physical and Chemical barriers;
1) Physical Barrier
As the name implies, physical barrier will stop termites from going though undetected entries into your home. They simply can not go any further. These kinds of barriers are usually installed during the construction of the building. One of the most popular products is called Kordon from BAYER. It is a thick plastic orange color material. Sydney pest controllers will usually need to be certified in order to produce the documentation for their termite barrier work. There is an inbuilt pesticides in Kordon. As soon as termites come in contact with it, they will die. It is laid in the cavity between the bricks, between the concrete slab and the brick work, around the penetration and other area where termites can enter undetected.
Granitgard is another popular physical barrier against termites. It consists of heavy sandy granules where termites can not move or crawl through. Like Kordon, we install them as a barrier against undetected termite entry. TermiMesh is another Product that Sydney pest controllers use while installing termite barrier. As the name implies, it is a stainless steel mesh that termites can not chew or go through. The advantage of termimesh and Granitgard is that no pesticides is used in them.
2) Chemical Barrier
Chemical barrier is usually applied to the existing homes. There are 2 kind of chemicals available for this reason. Repellent and non-repellent chemicals.
Repellent chemicals are cheap insecticides! They are generally toxic to other animals and reptiles. Once termites come in contact with them, they die almost instantly. As termites sense the chemicals, they avoid the area and try to find a gap in the barrier. If the barrier is flawless, they can’t come inside your home. If the barrier has gaps, termites may be able to find the gaps and attack the property.
Non-repellent chemicals are much more expensive and much less toxic to other animals and humans. Termites won’t notice them while being infected and the best property of them is the delayed affect. It won’t kill termites strait away, so they have time to pass it to the other termites.
Chemical barriers can last up to 10 years depending on the chemicals and the concentration. If a non-repellent barrier is incomplete, you may still be successful in eradicating a colony that is attacking your home as termites forage randomly and even if part of the colony is being infected, it can still help the demise of the colony.
If your home is on a concrete slab, perimeter barrier is the best recommended barrier. It involves drilling 4 holes a meter and injecting chemicals under slab. In those area where there is direct access to the ground, trenching is possible. We then flood the trench while mixing it with the earth.
If your home is on brick piers and there is access to the subfloor. Subfloor chemical treatment is the best termite barrier practice in Sydney. We always use non repellent chemicals to ensure the best result and safest outcome.
