Single ants don't have any idea, but anthills as a system probably have some kind of a working model of human activity. For example ants often feed off garbage cans so they know how the amount of garbage changes daily and weekly. I don't know how good ant systems are at generalizing and noticing patterns but if they are any good they probably know at least that about human civilization. Do they "think" of humans as another kind of anthill - probably not. But they certainly notice and react to changes in environment caused by human activity.
