Larder beetle larvae are appearing in a surprising number of samples we're receiving now. Brooks joked that spring cleaning probably became a tradition because it helps stave off dermestid infestations. Spring also is when vulnerable wools and furs go into storage and people begin to wear frequently washed linens and cottons. Vacuum the inside and outside of furniture, especially any drawers and upholstery. East of the Rocky Mountains, the domestids cause almost all of the fabric damage found in the northern states.
Clothes moths are more likely to be a problem in the south.
Fortunately, however, cleaning and storing fabrics properly also helps prevent damage by either pest. Further protection is possible for specimens in museum cases and for clothes in cedar chests or tight boxes. Even so, I suggest removing susceptible clothing from time to time to inspect it for infestations. Or, with expensive furs and garments, commercial storage may be the best preventative. Clean the infested area thoroughly with a vacuum cleaner and then soapy water.
