These small red to yellowish ants can be found trailing anywhere within a structure. They can nest in wall voids, cabinets, boxes of food and any other accessible crevices and spaces. They are known to invade sick rooms and feed on blood plasma and wound dressings. Their colonies have multiple queens and can split into small groups, spreading very rapidly.
In sub-tropical areas pharaoh ants readily nest outside in leaf debris found on or near structures. Re-invasion of the structure can occur throughout warm parts of the year.
