Mothballs or camphor balls that contain napthalene can be fatal to small children who swallow them, according to the University of California at Berkeley Wellness Letter.
Some mothballs contain potential carcinogens, and all kinds pollute the air.
Instead of using alternative products, such as cedar chips or dried lavender which may not work, take the woolens to the dry cleaner and wash the washable garments. Moths are attracted to spots of food and perspiration on clothes. Then store clothes in a sealed box or bag.
