Pharaoh's Ant

Monomorium pharaonis


Pharaoh's Ant
  • Workers are 1.5–2mm in length, yellow–brown in colour, with brown abdomen.
  • Males are 3mm in length, and are black and winged.
  • Queens are 3.5–6mm in length, dark red in colour, with wings.
  • Pharaoh’s ants have black eyes, and two small segments at the pedicel.


  • The Pharaoh’s Ants are known to have multi–queen ant colonies.
  • Swarming of these ants can take place at any time of the year.
  • Winged adults seldom fly, which is why they are rarely seen. Their wings are soon lost after mating.


  • Well–defined trails are laid which are often associated with heating systems. This type of ant species feed indoors on high protein foods, such as meat, fats, blood, dead insects, etc.
  • Swarming characteristics: a new ant colony is often formed through nests that have been disturbed e.g., as a result of insecticide spray treatments. Each queen produces up to 3 500 eggs in its lifetime.
  • Ant nest locations: Pharaoh’s ants are deep seated in cavities in heated buildings, and are also often found in hospitals. These ants are associated with humid conditions. An ant colony can range from a few dozen to 300,000 individuals.
