Discovering new holes in a favourite jumper, suit or other valuable garment can be the first indication of clothes moth activity. However, the damage may have been developing for some time before it becomes visible.
It is the moth larvae, rather than the adult moths, that feed on natural fibres. Wool, cashmere, silk, fur, feathers and other animal-derived materials are particularly vulnerable, especially when stored in quiet, undisturbed areas.
For homeowners and property managers across London, where clothes moth activity is extremely common, protecting clothing starts with understanding which items are most at risk and taking practical steps to make wardrobes and storage areas less suitable for moth activity.
Why Do Clothes Moths Damage Clothing?
Clothes moth larvae feed on keratin, a protein found in many natural, animal-derived fibres. This is why damage is frequently discovered across woollen clothing, cashmere, silk, rugs and other natural textiles.
Several factors can make stored clothing particularly vulnerable:
- Natural fibres provide a food source: Wool, cashmere, silk, fur and feathers can all support developing clothes moth larvae.
- Worn clothing can be more attractive: Garments containing traces of perspiration, skin cells or food residue may be particularly vulnerable when placed into storage without being cleaned.
- Wardrobes provide undisturbed conditions: Dark, quiet areas allow larvae to remain hidden while feeding.
- Damage can develop unnoticed: Eggs and young larvae are extremely small, so activity may not become obvious until holes or thinning fabric begin to appear.
Adult moths do not cause the fabric damage themselves. Their presence can, however, indicate that eggs have been laid and larvae may be developing somewhere nearby.
Which Clothes and Fabrics Are Most at Risk?
Correctly identifying vulnerable items helps you prioritise what needs to be inspected, cleaned and stored more carefully.
Wool and Cashmere
Woollen jumpers, suits, coats, blankets and cashmere garments are among the items most commonly associated with clothes moth damage. Clothing that remains untouched for long periods can be especially vulnerable.
Silk, Fur and Feather-Filled Items
Silk garments, fur, feathers and other animal-derived materials can also provide a food source. This can include occasion wear, vintage clothing and feather-filled household items.
Carpets, Rugs and Upholstery
Clothes moth activity is not always confined to wardrobes. Natural-fibre carpets, rugs and upholstered furniture can also be affected, particularly beneath furniture, around edges or in other areas that are rarely disturbed.
Cotton and synthetic fabrics do not contain keratin in the same way as animal-derived fibres. However, soiled garments, fabric blends and items stored alongside affected materials may still require inspection.
How to Protect Your Clothes From Moths
From our experience, good storage and regular inspection can significantly reduce the risk of clothes moth damage.
1. Clean Clothes Before Storing Them
Wash or professionally clean garments before placing them into long-term storage. Always follow the item’s care label, particularly with wool, silk and other delicate materials.
Even lightly worn clothing can contain perspiration, skin cells or food residue that makes it more attractive to moth larvae.
2. Store Vulnerable Clothing in Sealed Containers
Place clean, seasonal clothing in suitable airtight containers or sealed garment bags. Avoid relying on open cardboard boxes or loosely tied bags, which provide limited protection.
Make sure items are completely clean and dry before sealing them away.
3. Vacuum Wardrobes and Undisturbed Areas
Regularly vacuum wardrobe floors, shelving, skirting boards and the areas beneath furniture. Pay particular attention to corners, carpet edges and places where natural fibres, hair or dust can accumulate.
Empty the vacuum immediately afterwards if moth activity is suspected.
4. Inspect Stored and Second-Hand Items
Check clothing periodically rather than leaving it undisturbed throughout the year. Look closely at seams, folds, collars, cuffs and areas that are less exposed to light.
Vintage clothing, second-hand garments, rugs and upholstered items should also be inspected before being introduced into the property.
5. Rotate and Air Your Wardrobe
Clothes moths favour quiet areas where fabrics remain undisturbed. Opening wardrobes, moving garments and airing suitable items can make these spaces less favourable while allowing you to identify early signs of damage.
Will Cedar and Lavender Protect Clothes From Moths?
Cedar, lavender and similar natural products may provide a limited deterrent, but they should not be relied upon to control an active infestation.
Their effectiveness can reduce as the scent fades, and they will not eliminate eggs or larvae already hidden within clothing, carpets or surrounding areas.
These products are best treated as an additional preventive measure alongside cleaning, sealed storage and regular inspection; not as a substitute for professional control where damage is already occurring.
Signs You May Have a Clothes Moth Infestation
Preventive measures are most effective before an infestation becomes established. Professional identification may be needed if you notice:
- Irregular holes or thinning areas across clothing
- Loose fibres or damage around garment seams and folds
- Larvae, webbing or portable cases inside wardrobes
- Repeated moth sightings near clothing or carpets
- Damage returning after affected items have been cleaned
- Activity spreading across several rooms or storage areas
Cleaning or disposing of one visibly affected item may not resolve the problem if eggs or larvae remain elsewhere within the property.
