Termites cause more damage to homes in Australia than fire, floods, storms and tempest combined. There is a high incidence of infestation in The Northern Territory which creates a serious problem for the NT parks and reserve. Recycled-plastic bollards provide the perfect solution. Timber bollards might create a delicious outdoor dining experience for termites, but it seems they have no appetite for recycled plastic.
If you have termites, take timber off the menu.
