Workers of the pharaoh ants (Monomorium pharaonis) are approximately 2mm in length and have body colours ranging from light-brown to red. The males are the same size as the workers but are black in colour. The queens are 4mm in length and slightly darker than the workers (Nickerson and Harris 2003).

Monomorium pharaonis the pharaoh ant) is native to Africa and has successfully invaded areas on every continent except Antarctica. It is concentrated in tropical regions but is also commonly found in temperate zones within suitable human infrastructure, especially buildings associated with the distribution or storage of food. Due to Monomorium pharaonis' ability to act as a vector for some bacterial human pathogens, its presence in hospitals is of great concern as it may increase infection rates.
