Pharaoh ants are tiny invasive ants commonly found in homes, apartments, hospitals, restaurants, and commercial buildings around the world. These small ants are known for their rapid colony growth, hidden nesting behavior, and ability to spread through walls, insulation, and plumbing systems. Although they are tiny, pharaoh ants can become serious indoor pests because colonies often contain multiple queens and thousands of workers. Different types of pharaoh ants may vary slightly in color, habitat preference, and nesting behavior. Learning to identify these ants can help homeowners understand infestations and improve indoor pest prevention strategies.
1. Pharaoh Ant
