Found small holes in your clothes or moths in your wardrobe? Learn how to identify clothes moths and larvae, prevent damage and treat suitable textiles through professional freezing.
What Are Clothes Moths and Why Do They Live in Wardrobes?
Have you noticed a small yellowish moth flying around your wardrobe? Found mysterious holes in a wool jumper or tiny larvae among your stored clothing? Clothes moths could be responsible.
Clothes moths are small insects whose larvae can damage textiles, particularly those made from animal-derived fibres. Woollen clothing, wool rugs, fur, blankets and other natural materials can provide food for the larvae. Finding clothes moths does not necessarily mean your home is unclean. They can arrive in second-hand clothing, textiles, furniture and other belongings.
Identifying the problem early can help protect valuable clothing and prevent further damage.
What Do Clothes Moths Look Like?
Adult clothes moths are small, often pale yellow or golden-coloured insects. They tend to prefer dark, undisturbed locations rather than brightly lit rooms. You may find them in wardrobes, storage rooms, attics and areas where clothing or textiles remain untouched for long periods. However, adult clothes moths are not the stage responsible for eating holes in your clothes. The damage is caused by their larvae.
What Do Clothes Moth Larvae Look Like?
Clothes moth larvae are small, pale or cream-coloured caterpillars, usually with a darker head. They can be difficult to spot because they hide in folds, seams and sheltered areas of textiles. Depending on the species, you may also notice fine silk-like webbing, protective cases or irregular damage to fabric.
Not every hole in your clothing is caused by clothes moths. Carpet beetle larvae can also damage textiles, making correct identification important.
Five Common Signs of Clothes Moths
- Small holes in clothing. Irregular damage may appear in wool and other animal-based textiles.
- Small moths near wardrobes. Pale yellow or golden moths may appear around clothing storage areas.
- Larvae among textiles. Look for larvae in seams, folds, drawers and rarely used garments.
- Webbing or larval cases. Some clothes moth species leave behind silk-like material or protective cases.
- Damage to stored belongings. Infestations are sometimes discovered when seasonal clothing is taken out of storage.
One sign alone may not be enough to confirm the species. If you are uncertain, photograph the insect or larva and seek identification from a pest professional.
What Do Clothes Moths Eat?
Clothes moth larvae feed primarily on animal-derived materials containing keratin, a protein found in wool, fur, feathers and hair. Mixed-fibre fabrics containing animal fibres can also be vulnerable. Soiled textiles may be more attractive under some circumstances. Purely synthetic fabrics are generally not a comparable food source, although damage may still occur in blended or contaminated materials.
This is why clothes moth problems are often associated with wool jumpers, rugs, suits and other valuable textiles.
How to Get Rid of Clothes Moths
The most important steps are identifying the source of the infestation and treating affected or potentially exposed belongings appropriately.
1. Inspect Wardrobes and Textile Storage Areas
Check woollen garments, blankets, rugs and other animal-derived textiles. Pay particular attention to seams, folds, the bottoms of drawers and rarely used belongings. Avoid carrying potentially infested items around your home without protection. Place suspicious textiles in securely closed bags before moving them.
2. Vacuum and Clean Storage Spaces
Thoroughly vacuum shelves, drawers, skirting boards and other sheltered areas. Dispose of the vacuum contents appropriately immediately afterwards. Cleaning may remove loose larvae, eggs and debris, but it may not be enough on its own to eliminate an infestation.
3. Wash Suitable Clothing According to the Care Label
Some garments can be treated through laundering if the material and care instructions allow it. However, wool, silk and other delicate fabrics require special care. Excessive washing temperatures can permanently shrink or damage clothing.
4. Consider Professional Freezing Treatment
Not every garment can be washed at high temperatures, and some valuable textiles are difficult to treat using conventional methods. Professional freezing may provide an alternative for suitable belongings. Freezing can be appropriate for many garments and textiles when the characteristics of the material and the target pest are properly considered.
At Jäähy, treatment is selected according to the belongings and the pest involved. We do not rely on guesswork: our expertise is built on more than ten years of hands-on experience and extensive in-house research and testing of pest insects and their response to cold.

5. Monitor the Situation After Treatment
Clothes moth pheromone traps may help monitor the presence of certain species, but they do not eliminate larvae or eggs hidden in textiles. Continue checking storage areas to make sure the original source of the problem has been addressed.
Can You Kill Clothes Moths in a Home Freezer?
Freezing can be an effective method of insect control, including in certain household situations. However, successful treatment depends on several important factors. Simply placing a garment in a freezer does not automatically guarantee that insects and all their developmental stages will be eliminated. What matters includes how thoroughly the material cools and whether the required cold conditions are maintained throughout the item. A thick pile of woollen clothing, a tightly packed suitcase and a single lightweight garment do not cool at the same rate.
We explore this subject in more detail in our article Why Thick Materials Cool More Slowly Than Thin Ones.
For valuable textiles or when you want a professionally controlled process, specialist freezing treatment is worth considering.
Can You Freeze Wool Jumpers, Rugs or Fur?
Many woollen garments and other textiles may be suitable for freezing. However, not all materials can be treated without risk. Special care may be needed for delicate finishes, glued components, decorations, leather, moisture-sensitive materials and particularly valuable items. Freezing also cannot repair holes or other damage already caused by larvae.
If you are unsure whether an item is suitable, contact Jäähy before making a booking.

How Can You Prevent Clothes Moths From Returning?
- Clean clothing before placing it into long-term storage.
- Store valuable woollen and other animal-derived textiles in clean, securely closed containers or protective bags.
- Inspect second-hand clothing, rugs and other textiles before bringing them into storage areas.
- Regularly clean wardrobes, storage rooms and seldom-used spaces.
- Watch for new larvae, moths and signs of fabric damage.
Preventing an infestation is usually easier and less expensive than dealing with a widespread problem later.
Clothes Moths or Carpet Beetles – Why Does Identification Matter?
Clothes moths and carpet beetles are different insects, although the larvae of both can damage textiles. A clothes moth is a moth, whereas a carpet beetle is a beetle. Their larvae also differ in appearance and behaviour. Correct identification can help you locate the source of the problem and choose an appropriate treatment.
If you are unsure what is damaging your clothing, do not assume the species based on holes alone.
