Moths, damp basements and permanent creases ruin more clothes than wear does. These six storage habits protect sweaters, coats and boots between seasons.
Quick take
- Clean everything before it goes into storage, because clothes moths are attracted to sweat, skin cells and food particles left on fabric, not just the wool itself.
- Fold sweaters and knits instead of hanging them; flat storage supports the whole garment and prevents stretched shoulders and permanently set creases.
- Vacuum-sealed bags with silica packets are a practical way to store wool when space is tight, and they protect knits from dust, moths and moisture.
- Store clothes somewhere cool, dry and dark, and treat basements with caution because excess moisture is hard on wool.
- Clean road salt off boots before storage and keep them upright so the shafts do not crease over the summer.
A winter coat or a good wool sweater costs real money, and the fastest way to shorten its life is to cram it into a garbage bag and forget about it until November. Off-season storage is where clothes quietly get damaged. Moths, musty smells, permanent creases and crushed boots all happen in the closet, not on your body. The fix takes an afternoon, and the habits below apply whether your wardrobe came from a department store or a thrift shop rack.
Why Off-Season Storage Ruins Some Clothes
Textiles are organic materials that deteriorate naturally when exposed to light, temperature swings, humidity, dust and airborne pollutants, according to the Canadian Conservation Institute (CCI). Preventive measures slow that damage down; nothing stops it completely. Most fabrics are also absorbent and porous, so they readily take on moisture, odours and stains.
Creases are a bigger problem than many people realize. A fold left in place for months can become permanently set, and prolonged creasing can eventually form splits in older or weakened fabric. Then there are pests. Clothes moths are drawn to fabric not only for the wool itself but for the sweat, skin cells, food particles and dirt sitting on it, so an unwashed sweater in a dark bin is an open invitation.
All of this adds up to a simple equation. Clothes that come out of storage in good condition get worn for years, while clothes that come out damaged get replaced, which is exactly the cycle that makes a cheap wardrobe expensive, as we explain in the real cost of a fast-fashion wardrobe.
Clean Everything Before It Goes Away
Soil invites infestation, which is why CCI treats cleaning as a basic requirement before anything goes into storage. Follow the care label on each piece; our guide to reading clothing labels in Canada explains what the fibre content percentages and care symbols actually mean.
For wool, hand washing is often the gentlest method. Use cool or lukewarm water, since hot water can shrink wool, along with a wool-specific detergent and gentle soaking rather than rubbing or wringing. Machine wash only if the care label says the item is machine washable, using the wool or delicate cycle with cold water and, ideally, a mesh laundry bag. Whatever the method, dry the item completely before it gets put away. Wool stored even slightly damp will smell musty by fall.
Before anything is folded, inspect it. Check knits closely along seams and fold lines for moth holes; our checklist for evaluating secondhand knitwear walks through the same warning signs, and they apply to your own closet too. CCI also recommends examining textiles for insects or mould before storage and isolating anything suspect in a sealed, clean polyethylene bag. Finally, pull out pins, staples and coloured tissue paper. Pins and staples put stress on fabric and are almost certain to rust, and coloured paper can transfer dye.
Fold Knits, Don’t Hang Them
Hangers are the wrong tool for knitwear. The weight of a heavy sweater pulls down on the shoulders, and over a season in storage that stretch can become permanent. CCI’s guidance points to flat storage as the ideal for most textiles because it supports the whole piece and frees the fibres from supporting their own weight.
Fold sweaters and store them in a drawer, on a shelf or in a bin, keeping folding to a minimum. If something will be stored for a long stretch, refold it along different lines partway through so no single crease sets in. Flat storage is also the right call for anything heavily decorated, bias-cut, or made with weak shoulder seams or stretchy knits.
Structured items are the exception. Coats and blazers with real construction hold their shape on a sturdy hanger, so hang those and fold the knits.
Choose the Right Containers for Each Fabric
No single container suits every fibre, and the right pick depends on how much space you have and what you are packing. Vacuum-sealed bags with silica packets are a widely recommended option for wool, especially in tight closets where bulky bins will not fit. Here is how the options break down:
| Item | Best container | Why it works |
|---|---|---|
| Wool sweaters | Vacuum-sealed bags or lidded bins with silica packets | Sealed storage with a moisture absorbent protects wool from dust, moths and damp |
| Cashmere | Its own bin, separate from wool | The two materials can compromise each other when stored together |
| Cottons and synthetics | Lidded bins | These tolerate airtight storage well |
| Bulky items in tight spaces | Vacuum-sealed bags with silica packets | Saves space, and silica absorbs residual moisture |
Packaging matters as much as the container. CCI advises removing paper wrappings other than acid-free tissue, especially coloured paper, because dyes can transfer onto fabric. Choose storage materials that will have no adverse effect on the fabric itself.
Control Moisture, Light and Pests
Location first. Pick a dry, cool spot, and treat the basement with caution, since excess moisture makes it a poor choice for wool. Light causes deterioration, so dark closet space beats an open shelf near a window. Silica packets or other moisture absorbers add another layer of protection inside bins and bags.
For pests, layer your defences. Clean fabric is the first and most important one, because moths are really feeding on what is left on the garment. Cedar blocks and chips, and sachets of lavender or cloves, are common deterrents people tuck between folded items, and vacuuming the storage area at the start and end of the season clears out lint and stray fibres that would otherwise become food.
Style tip
Low temperature is a recognized method for controlling insect pests in textiles. If you suspect moth eggs in a wool item, seal it in a plastic bag and leave it in the freezer for about a week before it goes into storage.
Storing Boots and Shoes So They Keep Their Shape
Boots need their own routine before they disappear for the summer. Road salt leaves stains on footwear that become far harder to deal with after months of sitting, so clean it off before storage; our guide to removing road salt stains from boots and shoes covers the steps. Let footwear dry fully away from direct heat, then store boots upright where nothing will press on the shafts, since boots left on their sides or under a pile of gear tend to come out creased and slumped. Keep them out of damp spaces for the same reason you keep wool out of the basement.
One thing that surprises people: overshoes and boots are exempt from Canada’s textile labelling requirements, so most footwear carries no care label. With no instructions to follow, a gentle, patient approach is the safe default.
A Simple Rotate-In, Rotate-Out Routine
Put it all on a twice-a-year schedule tied to the weather. When it is time to swap seasons, work through the same sequence every time:
- Wash or dry clean everything going into storage, and dry it completely.
- Inspect each piece for moth holes, mould or damage, and deal with problems before storing.
- Fold knits flat, hang structured pieces, and pack each fabric type in its proper container.
- Vacuum the closet or storage area you are emptying into.
- Note what you did not wear all season and set it aside to donate instead of storing it.
That last step matters more than it looks. Clothing you never reach for does not deserve shelf space, and clearing it out makes each future swap faster and the pieces you keep easier to find. Come spring or fall, the whole rotation takes an afternoon instead of a weekend.
Pick one category this weekend, whether that is sweaters or boots, and run it through the full clean, dry, fold and store routine before the season turns.

Your style questions
Q: Can I use vacuum-sealed bags for wool sweaters?
A: Yes. Vacuum-sealed bags with silica packets or other moisture absorbents are a widely recommended way to store wool, especially when closet space is limited. They also protect knits from dust and moths while they sit for the season.
Q: How do I deal with moth eggs before storing wool?
A: Low temperature is a recognized pest-control method for textiles. Seal the item in a plastic bag and leave it in the freezer for about a week before putting it away.
Q: Can I store wool and cashmere in the same bin?
A: It is better not to. The two materials can compromise each other when stored together, and keeping them apart makes it easier to check each group for moth damage.
Q: Where should I store winter clothes in my home?
A: Choose a dry, cool spot such as an interior closet. Basements tend to have excess moisture, which is hard on wool, and light accelerates fabric deterioration.
