Ants have the most advanced form of social life amongst the insects. Ants live in colonies that range from a few hundred to thousands. Most nest outside, but may venture inside in their never ending search for food. Ants feed on almost anything, carrying food back to the nest to feed the colony while leaving behind a pheromone trail for others to follow to the food source.

The life cycle of an ant consists of four stages: egg, larva, pupa and adult. Eggs are small and ovoid in shape. Fertilised eggs become females (usually sterile workers), but at certain times also fertile females (which can potentially become queens). Unfertilised eggs become males. The development from egg to adult may take from six weeks to very long periods, depending on the species, season and food availability.

Of all the species of ants, only a few have become pests of humans.

Black Ants

Black Ant (Ochetellus glaber)

Black house ants are 2.5-3.0 mm long, and intensely black with a sometimes subtle, purplish-green iridescence. They usually nest outside against paths, in rockeries and other cracks and crevices but will readily nest indoors between walls, ceilings, doors, fences and other unusual places, but rarely do they nest in the soil. A sign for locating nests is the fall out of black droppings on floors, window sills and benches which indicate nests above or near the droppings. Preference is for sweet foods but will eat seeds, plants, fats and grease. They are commonly found in homes due to their need for access to water. 

Coastal Brown Ant

Coastal Brown Ant (Pheidole megacephala)

Coastal Brown Ants are 1.5-2.5mm long. Their colour varies from light yellowish brown to brown. They nest mainly in soil and builds along pathways, in gardens, against walls, under houses and if in large enough numbers can cause damage to lawns. They prefer sunny, dry areas to nest but will nest above ground if soil is available. Can be found nesting in termite tracks. Have been known to invade external electrical appliances such as hot water systems. Preference is for fatty foods but will attack seeds, meats, insects, fruit, honeydew from aphids, sweet foods, fats and grease. This ant is spread mainly by human activity, such as the transfer of infested pot plants and landscaping materials to uninfested houses and gardens.
