American red cedar has a fragrant aroma that is pleasing to people but repels moths. Therefore, you can keep your clothes moth-free with cedar wood products. Place 2 - 5 cedar pieces up per wardrobe unit in such a way that they are not covered by clothes. In drawers or storage compartments 2 pieces are adequate. Place the cedar items on a piece of paper to protect the clothing from the oils in the cedar. When the scent begins to fade, rough the wood slightly with sandpaper. This type of moth protection is absolutely environmentally friendly, since American red cedar is not an endangered plant cultivated under governmental regulations.
