Pharaoh ant (Monomorium pharaonis)

Pharaoh ant

The origin of the Pharaoh ants is unknown. It is found throughout Australia and indeed in many countries globally.

Typically nests indoors in wall cavities, sub-floors, near heat sources and electrical outlets.

Multiple queens and multiple nests as part of the same colony. Budding can create building-wide infestations, with colonies containing hundreds of thousands of ants.

Colour: Light brown with darker abdomen
Size: 1.5 – 2.0 mm
Nodes on petiole: Two

Highly varied diet (protein, oils and sugar). Known to switch between protein and carbohydrate food sources.

  • Only active during the day
  • Can produce long-lasting trails
  • “Pits” in their cuticle give the head and thorax a dull appearance
  • Pharaoh ants do not sting / bite (humans).

Clearing up food spills, regular cleaning of the cooker and grill, and not leaving petfood out will make the area less attractive to Pharaoh ants.

Can sometimes be confused with the Singapore ant and big-headed ant

Other types of ants.
