If they can pull an insect into the nest, they also will be able to get rid of it. My ants always throw off remainings of insects they ate. If you don't want mold on food, do not give food directly into nest. Opening nest is always stressful for ants, and moreover, you will be happy to see ants foraging outside nest and gathering food. In general, in small colonies ants forage individually so you should give them insects not much larger than ant. Single Lasius niger worker can handle a mosquito or something of similar size. If foragers find something too big, they will eat it outside and then share food with ants in nest.
