What specific physical trait does the adult pharaoh ant possess?

The adult pharaoh ant is characterized by a dull yellowish to light orange coloration, which is a critical aspect of its identification. This specific color helps distinguish pharaoh ants from other ant species. Notably, their small size—typically ranging from about 1/12 to 1/8 inch—means they are rather inconspicuous compared to larger ants, which is an important consideration when identifying instances of an infestation. Moreover, their body structure and color can blend with various environments, reinforcing the significance of recognizing their distinct hue when monitoring for pest control.
