Pharaoh ants are small, yellow to light brown ants that are often found in homes and buildings. They are particularly known for their ability to infest areas like kitchens, bathrooms, and hospitals, where they search for food and moisture. Pharaoh ants are notorious for being difficult to control due to their ability to form multiple colonies, and they can quickly spread if disturbed. They feed on a variety of substances, including sugary foods, grease, and proteins. Pharaoh ants can carry bacteria and pathogens, making them a health concern. Professional pest control is often necessary to effectively eliminate these persistent pests.
