The Australian standards and Queensland Building Service Authority recommends inspecting your home for termites every 12 months. In some cases every 6 months if your home was attacked by termites initially. Even if you have had a termite barrier installed you will still need to have it inspected even though you have had a termite barrier installed. The reason for this is termites may still find a way around them and if you have a qualified termite inspector in you can be assured that the termites barrier is working and if there is termites found they will be treated free of charge.
