I am also a college student who stayed at home for nearly eight months. As for whether there are mushrooms in my dormitory, I'm not worried at all, because the bed board in our dormitory is steel. There is no board. It is definitely impossible to grow mushrooms, but a moldy quilt is a very likely factor. After the quilt is moldy, I suggest changing it directly, or throwing it away and replacing it with a new one. If mushrooms really grow on your bed, first, clean it up. If you don't clean it up, after you remove those visible mushrooms, it is very likely that mushrooms will grow again after a while. Besides, mushrooms grow very fast. Maybe you will sleep, and the mushrooms will grow very long the next day.
After cleaning mushrooms, first of all, ventilation must be kept dry, because many dormitories are really humid, and humidity is a paradise for mushrooms to grow. The first thing to do when returning to the dormitory is ventilation, because the dormitory may not have experienced it for such a long time. The air in the ventilation also has a certain taste. Ventilation contributes to air circulation and our health.
Buy some disinfectant after ventilation, not necessarily 84, such as medical disinfectant. For example, spraying some medical disinfectant on the board of long mushrooms can destroy the spores left by mushrooms, etc., and it can also allow you to carry out thorough disinfection so that some bugs and bacteria cannot survive.
