Sweaters are not for eating, but tell that to a closet moth. The worst thing about having moths attacking your wardrobe is you probably won't know until the damage is done. That's why precaution is key. Store clean, off-season clothing in air-tight containers, vacuum your closet regularly, and wipe down its interior once per season. You can also try a natural moth repellent like lavender sachets or these red cedar chips. Like these hanging cedar sticks from Amazon ($19.99).
