Find natural pest control in Australia.

Most Australian homes have timber frames which require protection from termites. The standard method is to lay a reticulated system around the perimiter of the building and pump in a chemical formula. If you want to avoid the use of chemicals, you will need to lay some form of physical barrier that termites cannot penetrate, such as steel or granite. For pest control companies that use chemicals, but aim to use the minimum and least harmful possible, look for companies advertising "integrated pest management".
