The following section highlights the most common household ants found in and around our homes.

White Footed Black House Ant (Technomyrmex albipes)

Pest Control Ants

The white footed black house ants are worker ants that are 2.5 to 3.0mm long. As can be seen in the following image, their body is shiny black, elongated and hearts-shaped. Their legs have pale tarsal segments. They have a large, rounded head with mandibles and long antennae. Their eyes are less than half the size of their head and they have no wings.

Often found in wooden stuctures and tree trunks, the white footed black house ant typically nest around buildings and in wall voids near kitchens. They are omnivorous with a preference for sweets and move quite slowly. Electrical switches are often a source of habitat. They can be seen to raise their abdomen (gaster) toward the source of a disturbance when alarmed.

Coastal Brown Ants (Pheidole megacephala)

Pest Control for Ants

These ants are also worker ants that are 1.5 – 3.0mm in length. Coming in two types of morphs, the larger morph functions as a soldier and has a bigger head. It is light yellowish-brown to brown and its body is elongated. With a large and rounded head, the apex sports large mandibles. While its eyes are small and less than half the size of the head, the antennae are longer than the head and prothorax and elbowed.

This species of ant can be located in large nests found in crevices, wall voids, rocks, pavers, under logs and around building foundations. In Australia, these ants can disrupt the natural enemies of citrus pests. Having said this, the coastal brown ants prefer animal protein and fat in comparison to the white footed black house ant (see above) that has a preference for sweet foods.

Another worker ant, these black ants are between 2.5 – 3.0mm in length. With an elongated, black body, they have a large and rounded head with large mandibles at the apex. Their antennae are longer than their head and prothorax and elbowed. Less than half the size of their head, their eyes are small.

Being common to Australia, the black house ant prefers sweet foods and will also eat seeds, plants, fat and grease. They invade kitchens, bathrooms, or other sources of water in order to have access to moisture. Nests can be found in crevices and cavities such as pavers, rockeries and brickwork.
