Pharaoh's Ant - Monomorium pharaonis
Transparent - light yellow to light Brown. Two nodes
Usually an indoor pest but can be found both indoors and outdoors. They are particularily hard to control due to their ability to split their colonies into 'satellite' colonies and re-breed to bolster their population.
Can create large problems in places where the spread of germs is dangerous e.g. hospitals and restaraunts.
Pharaoh's ants are usually attracted to sweet and greasy food sources
