How to Store Silk and Prevent Moths

Store silk clean, dry, cool and dark, in a breathable cotton bag rather than airtight plastic, away from sunlight and damp — and keep moths off with natural deterrents like cedar or lavender. The single most important rule is to always wash or air silk and let it dry fully before you put it away, because it's the body oils, sweat and food traces on worn silk that draw moths and cause yellowing, not clean silk itself. Get that right, fold or hang each piece appropriately, and good silk will come out of storage exactly as you left it. Here's the full method.

How to store silk the right way

The principles are simple and they all point the same way — keep silk clean, dry and able to breathe. Make sure every piece is freshly laundered or aired and completely dry first. Then store it somewhere cool, dry and dark, in a breathable container — a cotton storage bag, a pillowcase, or acid-free tissue for something precious — never sealed in plastic for the long term, which traps moisture and invites mildew. Fold knits and delicate pieces loosely so they don't stretch, and hang structured items like dresses and slips on padded hangers. That's most of the job done before moths even enter the conversation.

Why washing silk before storage matters most

This is the step people skip and regret. Clothes moths aren't actually drawn to clean fabric — they're drawn to the sweat, body oils, skin and food residues left on worn clothes, and their larvae feed on natural protein fibers like silk and wool. Put silk away unwashed and you're effectively setting a table for them. The same residues also oxidize over months into the yellow tinge that ruins white and ivory silk (more on reviving that in how to whiten yellowed silk). So a gentle wash and a thorough dry before storage is both your best moth deterrent and your best anti-yellowing measure, in one easy habit.

How to keep moths away from silk

With clean silk as your foundation, a few natural deterrents do the rest:

• Cedar — blocks, rings or a little cedar oil refreshed now and then; its scent repels moths.
• Lavender — sachets of dried lavender (or a few drops of the oil on a cloth) are a pleasant, effective deterrent.
• Airtight boxes for valuables — for a precious piece you're storing for a long time, a clean, dry, sealed container (with the silk fully dry first) keeps moths out entirely.
• Regular airing — take stored silk out occasionally, shake it, and let it breathe; moths dislike disturbance and light.

You can skip the old-fashioned mothballs — naphthalene is harsh, its smell lingers in fabric, and clean silk plus cedar or lavender does the job far more pleasantly.

Where to store silk — and where not to

Location matters as much as method. Good: a cool, dry, dark closet or drawer, ideally with a little airflow. Avoid: damp basements and laundry rooms (mildew), hot or sunny attics and shelves (heat and light fade and weaken silk), and long spells sealed in plastic (trapped moisture). If a spot feels humid, warm or bright, it's the wrong spot for silk. A breathable bag in a steady, shaded closet is really all good silk asks.

Long-term storage for precious silk

For heirloom or special pieces you're putting away for a season or longer, a few extra touches help. Wrap them in acid-free tissue (ordinary paper and cardboard can yellow silk over time), refold them along different lines every so often so permanent creases don't set, and check on them periodically for any sign of damp or moths. It's the same gentle logic as the rest of caring for silk clothing — a little attention now saves a beautiful piece later.

If you'd like silk worth storing well, our LS Silk US mulberry silk is 22-momme, 100% mulberry silk and OEKO-TEX certified — and, kept clean, dry and cool, it stays beautiful for years.

Storing silk, then, is mostly about what you do before you put it away: wash it, dry it, and tuck it somewhere cool and dark with a little cedar or lavender for company. Do that, and the moths go hungry while your silk waits, perfectly, for the next time you reach for it.
