Ants belong to the family Formicidae within the order of Hymenoptera – This group of insects include ants, bees, wasps, sawflies and wood wasps. In Australia, about 3000 species of ants are known.

Ants are social insects that live in more or less permanent nests. Being very common intruders in and around buildings, ants tend to be very familiar insects. They are commonly observed around and in foundations and in walls, roof voids, kitchens, lawns and gardens. As a group, ants are the most successful of all insects.

The most common small black ants are:
