Winter clothes are among the most expensive items in your wardrobe — wool coats, cashmere sweaters, down jackets — and they are also among the most vulnerable to storage damage. Moths, mildew, compression damage, and permanent creases are all preventable with a few hours of attention once per year. Here is the correct process for 2026.
What changed in 2026
- Vacuum storage bags got better — thicker material and more reliable seals, but down and wool specialists still recommend against long-term compression for insulated items.
- Under-bed drawer systems (modular, stackable) became the standard recommendation for flat storage over the old cardboard-box approach, which invites pests.
- Cedar became harder to fake — "cedar-scented" sprays have no insecticidal effect on moths; only real aromatic red cedar or genuine lavender essential oil deters them.
- Climate-controlled storage units dropped in price, making off-site storage worthwhile for very large wardrobes in small apartments.
The pre-storage rule: wash everything first
This is not optional. Moths are attracted to body oils, sweat, and food residue embedded in fabric — not to clean fabric. Stored unwashed wool is an invitation for larvae. Invisible stains also oxidize and set permanently in storage.
- Wash or dry-clean every item before putting it away.
- Let everything air-dry completely before folding — even slightly damp fabric mildews in a sealed container.

Hanging (stretches knits) |
How to deter moths
Moth larvae eat natural protein fibers — wool, cashmere, alpaca, silk, down. Synthetic fabrics are not at risk.
- Wash before storing — the most effective deterrent by far.
- Cedar blocks or cedar rings — aromatic red cedar emits oils that deter moths. Sand lightly every season to refresh the scent. Replace every 2–3 years.
- Lavender sachets — real dried lavender or lavender oil on a cotton pad works similarly. Refresh annually.
- Sealed containers — airtight plastic bins with lids keep moths out entirely. Good for items you are confident are clean and dry.
- Avoid mothballs — they are effective but toxic, and the naphthalene smell is extremely difficult to remove from fabric.
Space-saving strategies
| Strategy |
Best for |
| Vacuum storage bags |
Bulk bulky items like fleece or cotton throws — not down or wool |
| Under-bed flat storage bins |
Sweaters, scarves, off-season flat items |
| Over-door organizers |
Accessories, gloves, hats |
| Double hang rods |
Coats on the main rod, empty below for added hanging space |
| Shelf dividers |
Keeping folded stacks from toppling |
How to pick the right container
For wool and cashmere: use either a completely airtight plastic bin (keeps moths out entirely) or a breathable cotton storage bag with cedar inside. The breathable option is better for very long storage (prevents any moisture buildup), but only if cedar is fresh and the item is absolutely clean.
For down jackets: store uncompressed. A large bin or a pillowcase works. Compression for months on end damages down clusters and reduces loft permanently.
For structured wool coats: hang in a breathable fabric garment bag. Plastic dry-cleaning bags trap moisture and should be removed before storage.
Common mistakes
Storing without washing. This is the cause of the vast majority of moth damage and permanent staining. Always wash first.
Using plastic dry-cleaning bags for long-term storage. They trap moisture and create a humid microclimate inside. Remove them before storing.
Over-relying on cedar sprays. Sprays have a brief cosmetic scent but no lasting deterrent effect. Use real cedar blocks or lavender.
Cramming too tightly. Overpacking causes permanent creasing and, for structured items, shape deformation.
What to skip
- Mothballs — toxic, smell-contaminating, and largely unnecessary if you wash before storing and use cedar or sealed bins.
- Cardboard boxes for long-term storage — they are not airtight, attract insects, and can transfer acidity to fabric over years.
- Storing in an attic or basement without climate control — temperature swings and humidity create conditions for mildew and pest damage.
FAQ
How long can I store clothes before they need re-washing?
If washed before storing and kept in clean, dry, pest-free conditions, clothes store well for a full season (6–8 months). Multi-year storage needs recheck for cedar freshness and condition.
Are vacuum bags safe for down jackets?
For short periods (a few weeks), generally fine. For the entire off-season, avoid — prolonged compression damages down clusters and reduces loft that may not fully recover.
What do I do if I find moth holes?
Wash the affected item and everything it was stored with. Deep-clean the container and area. Replace cedar. Damaged items can sometimes be repaired by a tailor.
Do cedar blocks actually work?
Yes, but only real aromatic red cedar (not just cedar-scented products). The volatile oils deter adult moths from laying eggs. They do not kill existing larvae — which is why washing before storing is more important.
