Emily,
Welcome to Beemaster.
Ants do eat honey and will rob it. Try putting the legs in Coffee cans and add some oil. Make sure the weeds do not make a ladder to your hive.
Feeding is a double edge sward. Not only does it draw ants, it also causes robbing. Are the bees flying a lot or are they pretty much staying home. If they are not flying dry much, then you may need to feed them since they do not have any stored food. Feed inside of the hive, don?t use an entrance feeder or use a feeder that is at one hundred feet of away from your hive.
