You pull out your favourite wool jumper and notice a patchy hole near the sleeve. Confused, you check your wardrobe, only to find more damaged clothes, with fine fibres and powdery dust. The culprit? Likely clothes moths.
But what do clothes moths eat? And why do they seem to favour your best garments?
Clothes moth larvae feed on keratin found in natural fibres like wool, silk, fur, and feathers. They’re especially drawn to unwashed clothing containing sweat or skin particles. Wardrobes, drawers, and storage areas are high-risk spots. Regular cleaning and professional treatment can protect against costly moth damage.
At Sun Pest Control, we deal with fabric and textile pests like clothes moths frequently. If you’re seeing signs of damage at home or in your business, this guide will help you understand the root cause, and how to stop it.
What Are Clothes Moths?
Clothes moths are small, golden or beige-coloured insects that thrive in dark, undisturbed places. In the UK, the most common species are:
- Common clothes moth (Tineola bisselliella)
- Case-bearing clothes moth (Tinea pellionella)
Despite their name, it’s not the adult moths doing the damage, it’s their larvae. These tiny, white, caterpillar-like insects hatch from eggs and begin feeding immediately on the materials around them.
What Do Clothes Moths Actually Eat?
The larvae of clothes moths feed on keratin, a fibrous protein found in many natural materials. This includes:
- Wool
- Cashmere
- Silk
- Fur
- Feathers
- Leather
- Felt
These larvae digest fibres by breaking down the keratin within them. However, the problem goes beyond just clothing. Moths will also feed on:
- Upholstered furniture
- Carpets and rugs
- Curtains and soft furnishings
- Blankets, cushions, and even soft toys
Clothes moths are also attracted to clothing and materials that have absorbed sweat, body oils, skin cells, or food stains. That’s why garments that haven’t been worn or washed in a while are often the first to be damaged.
What Items Are Most at Risk?
Moth larvae favour quiet, undisturbed areas, so the most vulnerable items are often those tucked away in wardrobes or storage. At Sun Pest Control, we often treat infestations affecting:
- Winter coats and wool jumpers
- Vintage or heirloom garments
- Rugs, especially around the edges or under furniture
- Upholstered chairs and sofas
- Stored curtains or drapes
- Clothing in sealed suitcases or storage bags
Moths can cause considerable and expensive damage, especially if they go undetected.
What Attracts Clothes Moths?
Understanding what draws clothes moths to your home can help prevent infestations. Here are the main triggers:
1. Dark, Undisturbed Spaces
Clothes moths prefer places with little activity, like the back of a wardrobe, under the bed, or inside drawers.
2. Natural Fibres
They’re specifically looking for materials with keratin, which synthetic fibres don’t offer.
3. Dirty or Unwashed Fabrics
Sweat, food residue, and skin cells boost the nutritional value for larvae.
4. Warm, Humid Conditions
Heated homes or poorly ventilated wardrobes offer an ideal breeding environment.
5. Long-Term Storage
Items that haven’t been disturbed for months are prime real estate for moths.
Signs of a Clothes Moth Infestation
A few holes in clothing may not seem like much at first, but they’re often the tip of the iceberg. Watch out for:
- Irregular holes in garments, especially around seams
- Silky threads or webbing inside wardrobes or drawers
- Pale larvae or empty casings stuck to fabrics
- Fine powder or droppings at the bottom of drawers
- Sightings of small moths, usually fluttering near skirting boards or wardrobes
- Damage to carpets, particularly around edges or under furniture
If you’re seeing more than one of these signs, it’s likely there’s an established infestation.
Why DIY Moth Treatments Often Don’t Work
Home remedies like sachets of lavender or cedar can deter adult moths, but they don’t treat the eggs or larvae. And sticky traps may catch flying moths, but not the root problem.
Here’s why most DIY attempts fail:
- Eggs and larvae are hidden deep in fibres, cracks, and corners
- The life cycle continues, with new moths emerging weeks later
- Chemical sprays may miss key areas or pose safety risks in the wrong hands
- Identifying the species and nesting areas is tricky without experience
That’s why many homeowners turn to professionals after repeated failed attempts.
