Figs tempt a range of scavengers. You'll see a wire fence in the background. That protects the figs from the dog (or the dog from the figs--these sweet fruits have devastating digestive impact). The foil strips glitter and are meant to keep away hungry birds (nice theory, shame about reality). Finally, the plastic bottles hold a mixture of Vegemite, sugar and water that manages fruit fly infestation--and now you know why Aussies are crazy about Vegemite! we're part drunk fruit flies.
