I am not the best housekeeper by far but I do not let garbage such as paper plates, containers with food/drinks of any kind sit. It immediately goes to the dumpster. Same thing goes for dry foods and refrigerator foods. I do keep the dishes up. Pet food goes into a large tote with a lid. I don't want pests in my food or my pets' foods. Just a little at a time is all it takes. When it seriously affects your heath then it really is time to do something. Those hoarding shows just show how dangerous it can be when it goes for too long. when the facilities cannot be used for their intended purposes then hoarding has gone that.
