Garments should not be placed in chests without first having been beaten, brushed, and sunned to remove the larvae. This treatment, advised as a preliminary for all materials intended for storage in cedar chests, if painstakingly done should remove even younger and
smaller larvae. Any larvae remaining, however, and entering the chests with the clothing are apt to be very young or very small. This is a most important fact, as cedar chests kill only very young or small larvae.
Today, many people dry clean or wash woolens prior to winter storage. This also removes the larvae. Clothes moths are active in the warm summer when woolens are not worn or checked regularly and the larvae can damage clothes without much notice.
