Moths in bedding: how to recognize them and get rid of them
You open your wardrobe or take out an old duvet and notice that the fabric is damaged. Small holes, as though something has been chewing on it. Or perhaps you find small insects or their larvae. These could be moths — and this is not a problem you should ignore.
Moths in bedding are more common than many people imagine, especially among those who store seasonal duvets or pillows deep inside a wardrobe for long periods. The good news is that you can get rid of them. You just need to know how.
What are moths and why do they appear in bedding?
Moths are small flying insects whose larvae feed on fibres from natural materials. The most important thing to understand is that adult moths themselves do not damage bedding. The damage is caused by their larvae, which feed on keratin-containing materials such as wool, silk, hair, down and feathers.
This means that moths are generally not interested in synthetic bedding. However, a wool duvet, silk bedding, down duvet or pillow with a natural filling can provide an excellent food source for moth larvae.
Moths do not like light or frequently disturbed areas. They prefer:
- Dark, quiet corners
- Items that have not been used for a long time
- Damp environments
- Natural fabrics, especially those containing traces of human sweat or body oils
This is why seasonally stored bedding is particularly vulnerable — it may remain undisturbed for months in a dark part of the wardrobe and is not always stored correctly.
How to recognize moth damage
Visible signs
Small, irregular holes in the fabric — this is a classic sign that moth larvae have been feeding on the material. The holes are usually irregularly shaped and look different from mechanical damage.
Thin, silvery webbing or silky threads — moth larvae may leave behind fine silk-like threads that can sometimes be seen on the surface of the fabric.
Small white or yellowish-white eggs — moth eggs are extremely small, around 0.5 mm, white and usually laid around seams, folds or other protected areas of the fabric.
Larvae — small, up to around 1 cm long, whitish and usually with a darker head. They actively avoid light, so they are more likely to be found in darker or hidden parts of the fabric.
Adult moths — small, approximately 1–2 cm long, golden or brownish moths. If you see them flying around your wardrobe or bedding, it is a clear warning sign.
Moth droppings — extremely small dark specks on the fabric or around it.
Smell
Moth-infested bedding can sometimes develop a distinctive heavy smell resembling mould or something old and musty. This is not necessarily caused directly by the moths, but it can indicate the same conditions that are favourable for moth activity.
How to get rid of moths — step by step
1. Isolate affected items
The first step is to immediately place affected bedding or duvets into a tightly sealed plastic bag. This helps prevent moth larvae from spreading to other items in the wardrobe.
2. High temperature — one of the most effective methods
Moth larvae die at high temperatures. This means:
Washing at 60°C — this is a highly effective method for textiles that can safely be washed at this temperature. It can destroy both larvae and eggs. Always check the care label first, as not every fabric can tolerate 60°C.
Drying at a high temperature — if the item cannot be washed at a high temperature, drying it in a tumble dryer on a high setting for at least 30 minutes may also help destroy larvae.
For silk or down bedding — these materials generally cannot be washed at 60°C. In this case, consider:
- Professional dry cleaning, making sure to mention the moth problem
- Freezing, as described below
3. Cold — an alternative for items that cannot be washed at high temperatures
Moth larvae can also be killed by very low temperatures. Place the bedding in a tightly sealed plastic bag and keep it in a freezer at -18°C or colder for at least 72 hours. Afterwards, allow it to thaw and wash it normally according to the care instructions.
4. Clean the wardrobe
Moth larvae may be present not only in the bedding but also inside the wardrobe itself — in corners, seams, cracks and underneath shelves.
- Remove everything from the wardrobe
- Vacuum thoroughly, paying particular attention to corners and cracks
- Wipe the wardrobe surfaces with a solution of vinegar and water or a suitable insecticidal product
- Allow the wardrobe to dry completely before returning the bedding
5. Moth traps
Pheromone moth traps are a useful way of monitoring whether moths are still active. They attract adult male moths and can help you determine whether the problem has been resolved or whether further action is necessary.
Important: traps do not solve the problem by themselves — they are primarily a monitoring tool. Captured adult males can no longer reproduce, but the traps do not affect larvae that are already present.
How to prevent moths
The best way to deal with moths is to prevent them from becoming established in the first place. Here are some preventive measures that can help.
Proper storage
Bedding is particularly vulnerable to moths when it is stored incorrectly. Before storing seasonal bedding:
- Always wash it before storage, even if it looks clean. Traces of sweat and body oils can attract moths.
- Store it in tightly sealed bags or vacuum storage bags. Properly sealed plastic helps prevent moths from reaching the textiles.
- Use dedicated bedding storage boxes with tightly fitting lids.
Natural moth repellents
There are several natural products traditionally used to help repel moths:
Cedar wood — cedar blocks, balls or hangers placed inside the wardrobe can help discourage moths. The essential oils contained in cedar act as a natural insect repellent. Over time, the cedar scent fades — lightly sanding the surface with fine sandpaper every 6–12 months can help refresh the aroma.
Lavender — dried lavender or lavender essential oil is one of the most popular natural moth repellents. Place a small bag of dried lavender inside the wardrobe or between layers of bedding.
Cloves, cinnamon or sage — the scents of these spices and herbs may also help repel moths. Place a small amount inside a fabric pouch and hang it in the wardrobe.
Essential oils — eucalyptus, rosemary or peppermint. A few drops applied to a small piece of cotton fabric and placed in a corner of the wardrobe can be used as a scented moth deterrent.
Regular airing and light
Moths prefer dark, undisturbed environments. Air out your wardrobe regularly — at least once a month, remove the bedding and allow fresh air to circulate through the wardrobe. If possible, avoid keeping the storage area constantly dark and damp.
Regular inspections
If you own bedding made from natural materials — such as wool, silk or down — inspect it regularly, at least once per season, for signs of moth activity. A problem detected early is much easier to deal with.
Special attention for owners of natural bedding
If you use bedding made from natural materials such as silk, wool or down, it is worth remembering that these materials are more vulnerable to moth damage than synthetic fabrics.
This does not mean that natural materials should be avoided — they offer many desirable qualities for sleep and comfort. However, they do require more careful storage.
Simple rules:
- Always wash or professionally clean bedding before storing it
- Store it in tightly sealed packaging
- Use cedar or lavender as moth deterrents
- Inspect it regularly
You can find a wide selection of bedding made from natural materials — including silk, wool and other options — in the Savashome collection.
Summary
Moths in bedding are a serious but manageable problem. The most important steps are to isolate affected items, destroy the larvae using high or low temperatures, thoroughly clean the storage area and introduce preventive measures for the future.
And the most important rule: always store bedding — especially seasonal bedding made from natural materials — correctly. A few minutes of proper preparation before storage can save you a great deal of trouble later.
