I would consistently feed a good source of carbohydrates and proteins. Good carbohydrates would preferably be honey but sugar water also works as another alternative as already mentioned above. A good protein source includes that of mealworms and dubia roaches (I use these to feed my ants but since ants are omnivorous and can eat anything you can basically feed them whatever protein or sugar source you want). I would on an average feed them once or twice a week with honey or sugar water on the 1st week and protein on the 2nd week. Although really, It is truly just up to you on when you want to feed them but make sure to switch back and forth on both carbohydrates and protein. Before feeding them though, consider checking the queen and workers gaster’s/abdomens to see if they are filled with any of the food you are giving them. This shows if they are actually liking what you are giving them because some species are picky when it comes to eating especially as young colonies (you’re lucky that it’s not Tetramorium as they are more omnivorous then that of species like carpenter ants in my area at least). Along with this but it also shows you when to feed them and I usually just follow feeding like this (seeing if the workers gaster’s are filled or not filled) instead of making fixed feeding times since it is easier to do this way. All you have to do is this: If the ants gaster’s are full, wait a few weeks (wait till their gasters are not filled) and then feed them either carbohydrates or protein depending on what they ate last. If they are not full then feed them on that day or the following. Whatever you do just make sure you are consistently feeding both proteins and carbohydrates to your colonies to ensure they receive proper health and care. Good luck!
