text: It depends on what kind of ants.  Mostly they like energy foods - sugar and proteins.   Leafcutter ants for example chew up leaves into pulp and 'farm' fungi, which they eat.  Some (the honeypot breed) like foods like nectar.  Another breed 'milks' aphids hat secrete sugars after they eat.\n\nThey will eat insects and some army ants will eat just about anything that can't get away fast enough.  Plants, critters, the like.  They also sometimes eat their own eggs.
