Whats a pharaoh ant?
Pharaoh ants live in Europe, the Americas, Australasia and Southeast Asia. Pharaoh ants are a tropical species but they thrive in buildings anywhere, even in temperate regions provided central heating is present. Colonies contain many queens (from 2 to over 200). An individual colony normally contains 1000 – 2500 workers but a high density of nests gives the impression of massive colonies. http://en.wikipedia.
