Pharaoh Ants are often mistaken for the Argentine and Thief ant-they are slightly smaller, less than 1/16th inch, and are a yellowish to brownish color. The also have a stinger, even though it is very small and not effective, which the Argentine Ant lacks. This ant will nest inside buildings, trying to find a location near food. It will eat just about anything that people eat-especially fatty, greasy foods, meat, and sweets. It is also a predator to many insects, and will spread bacteria. The unusual name comes from its original habitat in Egypt. The Pharaoh Ant seeks to establish nests in warm and inaccessible locations. A colony contains many queens and can have hundreds of thousands of workers!
