I can't verify that these tips work, but here's the article anyway!

Now that spring has arrived and warm weather is taking hold, we can pack away our woolens until next year. There is no longer any good reason to use napthalene moth balls to protect wollens from wool moths, now that they have been categorized as carcinogens.
Instead, learn how to compose a sweet smelling sweater chest using the herbs that weavers use to repel wool moths! Weavers can't take the chance of moths eating their skeins of wool, so their choices of repellent herbs really work.
Find out the simple steps to repelling clothing moths naturally, keeping your woolens safe all spring and summer long.
Before packing woolens away, there are a number of important steps to take to prevent moths, including washing the wool. Here you can learn about how to wet clean wool without shrinkage, how to make your own natural moth balls (repellent sachets), and what to do if you already have clothing moths.
How to Repel Clothing Moths
2 ounces each of dried rosemary and mint
1 ounce each of dried thyme and ginseng
8 ounces of whole cloves
Combine the ingredients in a large bowl. Blend. Make sachets by choosing a 4 x 4 inch piece of natural fiber with a tight weave, such as silk. Sew three sides together, then fill with the herbs and sew the fourth side shut. You can adapt this pattern to any size you want (2 x 2 is the traditional size for the undergarments drawer, for example). A good idea for small sachets is to fill cotton teabags sold for making your own tea (these are often sold in health food stores). If you are really in a rush, just tie the herbs up in a cotton bandana or handkerchief; place the herbs in the middle, gather the edges together, and tie with a ribbon.
Variation: Other herbs that are good for repelling moths include lavender, lemon, sweet woodruff, and tansy.
