Your alpaca sweaters, scarves, and socks will only survive the winter of 2026 unharmed if you store them correctly – otherwise, clothes moths will have a field day in the spring.
- Store alpaca clothing moth-proof with clean, dry wool in breathable cotton bags – cedar wood is recommended over mothballs.
- Lavender and cedar wood deter moths but do not replace thorough cleaning before storage in 2026.
- Airtight sealed plastic or vacuum bags flatten the fiber structure and are not suitable for alpaca wool.
- Check stored items every 2 to 3 months – moths usually lay their eggs unnoticed in seams and cuffs.
Why this is important
Alpaca wool contains significantly less lanolin than sheep's wool, which makes it slightly less appealing to clothes moths. Less appealing, however, does not mean uninteresting – moths feed on keratin, which is found in every animal fiber, including alpaca.
At Tre Alpacas, every winter we see the same question in our inbox: Why does my favorite scarf suddenly have holes after the summer break? Most of the time, it's not due to poor quality, but incorrect storage – unwashed residues of skin flakes and sweat literally attract moths.
If you're investing in high-quality alpaca clothing in 2026, you shouldn't skip the few steps for storage. It takes you ten minutes per season – and, if in doubt, saves you a piece of clothing that took several weeks of handwork.
What you need
- A mild wool detergent without enzymes
- Breathable cotton or linen bags, no plastic bags
- Cedar wood pieces or lavender sachets
- A cool, dry wardrobe or chest of drawers, not an attic with temperature fluctuations
- A folding board or a flat surface for neat folding
- If necessary, a piece of wool as a test area, such as your Alpaca Scarf made of Baby Alpaca Wool, to try out the storage method before the entire collection is tackled
The steps
1. Clean each item before storage
Moths are attracted to skin flakes, sweat, and food residues, not the wool itself. Wash sweaters, socks, and scarves at a maximum of 30 degrees on a wool cycle or by hand before they go into the wardrobe.
Most common mistake: Clothes still look clean and are put away unwashed. These are precisely the items most often infested in spring.
2. Dry the wool completely
Residual moisture not only promotes moths but also mold. Lay items flat to dry, never hung, otherwise, the shape will distort.
Only when an item feels completely dry inside and out should it be placed in the storage bag. This can take 24 to 48 hours for thick alpaca wool.
3. Fold instead of hang
Alpaca wool is light, but on hangers, it still stretches over months. Instead, fold sweaters, scarves, and hats neatly and stack them flat in the wardrobe or chest of drawers.
Expected effect: The fit is preserved, and you save space compared to hanging storage.
4. Pack in breathable bags
Cotton or linen bags allow air to circulate and prevent moisture buildup. Airtight plastic or vacuum bags, on the other hand, compress the fiber structure and can permanently flatten the typical crimp of the alpaca fiber.
Common mistake: Using vacuum bags for space-saving – practical in the short term, bad for the feel in the long term.
5. Rely on natural moth repellents
Lavender sachets and untreated cedar wood reliably keep moths away without chemically burdening the wool. Place two to three sachets or pieces of wood between the folded items in each wardrobe compartment.
Cedar wood loses its scent and thus its effect after about 6 to 12 months – then light sanding of the surface helps to refresh the effect.
6. Control temperature and humidity
Moths and moisture like it warm and stuffy. Ideal for storing alpaca clothing is 18 to 20 degrees Celsius and a humidity of 50 to 60 percent.
An attic with summer heat or a damp cellar are both poor storage locations, even if they offer temptingly ample space.
7. Regularly check for infestation
Check stored items every 2 to 3 months, even if they are not currently being used. Clothes moths prefer to lay their eggs hidden in seams, cuffs, and turn-ups, where they are easily overlooked.
If you discover small holes or fine webbing, immediately wash the affected item again and then freeze it for 48 hours at minus 18 degrees – this reliably kills eggs and larvae.
Troubleshooting
You find holes even though there was lavender in the wardrobe. Lavender deters adult moths but does not prevent an already existing infestation. Wash the item, freeze it for 48 hours, and replace the lavender sachets, as they lose their effectiveness after 4 to 6 weeks.
The wool smells musty after storage. This indicates residual moisture or a poorly ventilated wardrobe. Ventilate the wardrobe completely for a day and in the future only store fully dried clothes.
Cedar wood no longer smells. The essential oils evaporate over time, usually after 6 to 12 months. Lightly sand the surface with fine sandpaper to release the scent.
You discover fine white webbing in a seam. These are typical traces of moth larvae, even if no hole is visible. Immediately wash the item and check all neighboring items in the same compartment.
Condensation forms in the wardrobe. This often happens on outer walls in winter and promotes mold in addition to moth infestation. Move the wardrobe slightly away from the wall and use a small dehumidifier granulate if necessary.
Tools and Resources
- Mild, enzyme-free wool detergent for basic cleaning
- Cotton or linen bags instead of plastic packaging
- Cedar wood pieces or lavender sachets to add
- A special wool detergent for alpaca textiles that protects the fibers and leaves no residues that could attract moths
- A hygrometer for under 15 Euros to monitor humidity in the wardrobe
What you should do next
If you also store alpaca duvets or pillows, slightly different rules apply than for sweaters and socks, because the filling needs more volume to breathe. A separate guide to duvet storage explains how to maintain fluffiness and loft over the summer without the filling clumping.
FAQ
How can I store alpaca clothing moth-proof?
Wash and dry clothing completely, fold instead of hanging, and store in breathable cotton bags with lavender or cedar wood. Check items for infestation every 2 to 3 months.
Are alpaca products less susceptible to moths than sheep's wool?
Alpaca wool contains significantly less lanolin than sheep's wool, which makes it slightly less attractive to moths. However, it is not completely immune, as moths eat keratin, which is found in every animal fiber.
Are mothballs suitable for alpaca wool?
Classic mothballs with naphthalene are not ideal for alpaca wool because their strong odor clings to the fibers. Lavender and cedar wood work just as well without chemically burdening the wool.
Can I store alpaca clothing in vacuum bags?
Vacuum bags are not a good choice for alpaca wool because the pressure can permanently flatten the fiber structure. Breathable cotton bags protect just as well from moths without altering the feel.
How often should I check stored wool clothing?
Check stored items every 2 to 3 months, even if they are not currently being worn. Moths prefer to lay their eggs hidden in seams and cuffs.
At what temperature should I store alpaca clothing?
18 to 20 degrees Celsius with 50 to 60 percent humidity are considered ideal for storing alpaca clothing. Attics with strong temperature fluctuations or damp cellars are poorly suited.
How often do I need to replace lavender sachets in the wardrobe?
Lavender sachets lose their effectiveness after about 4 to 6 weeks and should then be replaced. Cedar wood lasts longer but loses its scent after 6 to 12 months and then needs to be sanded.
What should I do if I discover moth infestation on an alpaca sweater?
Immediately wash the item on the wool program and then freeze it for 48 hours at minus 18 degrees to kill eggs and larvae. Then check all adjacent items in the same closet compartment.
One more thing
Most moth damage doesn't occur in winter, when clothes are worn constantly – it happens in summer, when no one is looking. Mark a firm date in your calendar for 2026 to go through your stored alpaca clothing, instead of trusting that lavender alone will do the job.
“Moths don't eat wool; they eat what's still clinging to it – washing beats any moth repellent.”
