 Introduction:
Its name resulted from the mistaken belief of Linnaeus that
this ant was one of the plagues of Egypt in the time of
the Pharaohs. Pharaoh ants are thought to be native to the
African region. This ant is found throughout the United
States. Pharaoh ants have been strongly implicated in the
spread of various disease pathogens.
