Ants are social insects that are easily identified by their distinctive node-like bodies and elbowed antennae. There are currently about 3000 species of ants known to live in Australia. They usually build their nests amongst rocks, or in soil or in wood. In relation to their feeding habits, ants may be scavengers, or predators, and can vary their diet to suit the available local food supply. They can be commonly observed crawling along foundations and in walls, kitchens, roof voids and gardens
