WHAT ANTS FEED ON
Fire ants feed on honeydew, sugars, proteins, oils, seeds, plants and insects. Pharaoh ants feed on sugars, proteins, oils and insects. Crazy ants like sugars, protein, and insects; carpenter ants prefer sugars and insects.
Florida carpenter ants feed on honeydew from sucking insects and household food scraps and do not damage sound wood to any extent. They excavate galleries in wood to rear their young.
When a scouting ant finds promising food, she carries it or a piece of it back to the nest. Some ants leave scent trails that others can follow to the food source. Ants require water and will travel some distance for it if necessary.
PREVENTION
Relatively small ants, such as the white-footed ant can fit through extremely small openings to gain access into the home. If these entry points can be located, they can be blocked by application of caulk or some other exclusion device. This can also help to prevent other insects from gaining access into your home.
Any type of food or food particles can attract and provide food for ants. Store food in tight containers. Remove plants that can attract ants or control aphids, whiteflies and other insects that produce honeydew. Reduce moisture sources, including condensation and leaks.
