Mothballs have the function of preventing insects and mildew. In daily life, mothballs can be placed directly in the wardrobe, which can prevent clothes from getting damp and moldy. But if you want to put mothballs in the wardrobe, you must put them in the corner of the upper wardrobe and wrap them with paper or gauze to avoid direct contact with clothes. In this way, the gas of mothballs can slowly spread to the whole wardrobe, and at the same time, it can also prevent children at home from touching it.
