Ants, like all other animals, produce organic waste. If left to sit in their homes, it may lead to attracting predatory insects, disease, or parasites. To make sure this isn’t the case, some of the ants are assigned the task of taking out the garbage, including excrement, carcasses of previous prey, and all of the dead. This is not a safe job, as in the human world. They are unable to interact with food on their own and are confined to the area which has been designated as the landfill.
