Black Ant:

Known as a garden ant usually nests outdoor in flower beds, pots, beneath paving stones. Premises usually invaded by working ants foraging for food. During summer winged females (queens) and sexually matured males will produce from the nest and will emerge in large numbers over a short period. This swarming occurs in many nests at the same time in the afternoon. During the swarming which may last 2-3 hours the ants mate and eventually settle down exhausted.

 The males usually die quickly and a small portion of mated females will survive to find new colonies.
For control if possible trace the worker ants to the nest th en the nest can be removed or destroyed using  insecticide dust or a barrier can be formed using insecticidal spray to keep the foraging ants away or a bate can be used which the foraging ant will take to their nest which causes the ants to destroy the nest after the queen has died.

 Pharaoh Ant:

Unlike the black ants this species of ant will always nest within the foundation of a building have more than one queen. Infestation is spread by “budding”. Groups of workers and sometimes queens leave the main nest with brood to form satellite colonies. The worker ants are much smaller than the black ants they have a yellow/brown colouration and will forage any sweet or protein based organic matters. There is evidence that the pharaoh ants can carry pathogenic bacteria which could spread infection.

For control the use of conventional insecticides are not recommended for pharaoh ants, as this will almost certainly cause the ants to form satellite colonies.

Gel bait or granule bait is available and this should be placed where the worker ants forage. For this species treatment of adjacent properties may also be considered for better control.

Fire Ant:

Red imported fire ants nest in soil and build mound nests. They can infest garages. Red ants will build large mound nests, and will sting humans who come across a nest.

Red imported fire ants will build their nest mounds outdoors in landscape areas or near a structural foundation. The fire ant will gain entry to a building through holes or cracks.

The sting of a red imported fire ant is painful and often results in a raised welt that becomes a white pustule. Often, a person stung by a red imported fire ant receives multiple painful stings from more than one of the ants. Persons allergic to insect stings will react more severely.

Roger ant


Reddish brown in colour.
Workers 2mm long.
1 large segment at the pedicel.
1st two segments of the abdomen are constricted.

Workers forage randomly and lay no trails as live prey are hunted, especially springtails. Rarely seen outdoors.

Swarming characteristics — will swarm all year round. Winged adults are often found in electric fly killers.

Nest locations — damp residues and debris. Crevices around drains and behind broken wall tiles.


Ghost Ant

  Feeding – indoors: sweet substances and grease; outdoors: insects that produce honeydew.

  Nesting – indoors: small spaces, wall voids; outdoors: in flowerpots, under objects on the ground, under loose bark.

  Locations - attracted to high moisture areas, can be found in kitchen and bathroom cabinets.

  Colonies can occupy several different nesting sites.
