Clothes moths are pests that can destroy fabric and other materials. They feed exclusively on animal fibers, especially wool, fur, silk, feathers, felt, and leather. These materials, which contain keratin, are especially tasty to the larvae of clothes moths. Cotton and synthetic fabrics such as polyester and rayon are rarely attacked unless blended with wool, or heavily soiled with food stains or body oils. 

Clothes moths are small, 1/2-inch in size and are beige or buff-colored. They have narrow wings that are fringed with small hairs. They are often mistaken for grain moths that like to get into stored food items in kitchens and pantries. Unlike some other types of moths, however, clothes moths are seldom seen because they avoid light. They prefer dark, undisturbed areas such as closets, basements and attics. This is why you will find them tucked away in the folds of your woolens or deep in your yarn stash!

1. Wash before storing. Moths lay eggs in dirt, so wash your knitwear before storing it to be sure all residual dirt and body oils are cleaned away from the knit.
2. Store in airtight containers. Store your clothes in an airtight bag or plastic container to prevent moths from getting to them. This is a great tip in general for your knits or yarns, even if you don't know if clothes moths are in your area! Better to be safe than sorry!
3. Store in cedar chest. Cedar repels moths, but make sure your clothing is clean and dry before storing it in a cedar chest. Wrap individual pieces in acid-free tissue paper. 
4. Use natural scents. Put dried herbs like lavender, cedar, rosemary, mint, thyme, and cloves in sachets to keep in your drawers. Change the sachets every six months.  Or try putting some of these oils on a cotton ball in a jar without a lid in areas where you store your knits.
5. Freeze. If you spot some moth debris, put your knitwear in a sealed freezer bag and freeze it for 24–48 hours to kill any eggs. 
6. Use moth traps. Place moth traps in every room to kill male moths and prevent them from fertilizing female moths. This can be helpful is you live in areas where clothes moths are very prevalent.
7. Use moth repellents.Use moth repellents. You can use natural moth repellent scent bags, knitwear mists, or wool detergent to repel moths and to keep them from laying eggs in your knits.
