Pharaoh Ants are very small, light yellow, to reddish brown in color, with the abdomen somewhat darker. Female Pharaoh Ants can lay 400 or more eggs in her lifetime. Most lay 10 to 12 eggs per batch in the early days of egg production and only four to seven eggs per batch later. At 80°F and 80 percent relative humidity, eggs hatch in five to seven days. Unlike most ants, they breed continuously throughout the year in heated buildings and mating occurs in the nest. A single queen can produce many hundreds of workers in a few months growing to as large as 300,000, or more members. Nests are often so small it can be contained in a thimble, located between sheets of paper, in clothing or laundry, furniture, foods, etc. Nests usually occur in wall voids, under floors, behind baseboards, in trash containers, under stones, in cement or stone wall voids, in linens, light fixtures, etc. They prefer dark, warm areas near hot water pipes and heating tapes, in bathrooms, kitchens, counter tops, etc. They are “trail-making” ants and often are found foraging in drains, toilets, washbasins, and other unsanitary sites.
