Few pests are as quietly destructive as the common clothes moth (Tineola bisselliella). By the time you spot the damage – holes in a favourite jumper, a bare patch in a wool rug – the harm is already done. And here's the part that catches most people out: it isn't the fluttering moths doing it. The adults don't even feed; it's their larvae that quietly eat through wool, silk, fur and other natural fibres. So swatting the moths you see won't save your clothes – you have to deal with the eggs and larvae too.
We sell clothes moth traps, pads and treatments to households across the UK all year round – clothes moths don't really have an off-season in our centrally heated homes – and wardrobes and wool carpets are equally at risk. The good news is that protecting your clothes comes down to a few simple habits. Here are ten that work.
(If you're dealing with a full-blown infestation rather than protecting your wardrobe, our expert guide on getting rid of moths covers whole-home control.)
📋 Quick summary: protecting clothes from moths
- It's the larvae, not the moths – the flying adults don't feed; their larvae eat wool, silk and fur, so you have to tackle eggs and larvae too.
- Clean before storing – larvae are drawn to sweat, body oils and food traces on worn clothes.
- Store sealed – airtight bags or boxes keep moths off out-of-season clothes.
- Treat anything affected – freeze or hot-wash affected items to kill every life stage.
- Monitor, don't just deter – traps track adult activity; cedar and lavender deter but won't kill larvae.
1. Know Your Moths – and What Actually Does the Damage
If something's eating your clothes, the likely culprit is the common (or webbing) clothes moth – small, beige, with narrow, hair-fringed wings. It prefers dark, undisturbed spots and is seldom seen on the wing. A close relative, the case-bearing clothes moth, leaves tiny rice-grain cases and tends to go for carpets.
The key thing to understand is that the adult moths you spot don't eat fabric at all – the larvae do all the damage. Adults have no working mouthparts; they exist only to mate and lay eggs. So the goal isn't simply catching moths – it's stopping eggs being laid and killing the larvae already feeding.
One quick check: if you find threadbare patches but no moths, and small fibrous shells or shed skins instead, you may have carpet beetles rather than moths. Their damage looks similar, but moth pheromone traps won't catch them – so it's worth confirming which you've got before you treat.
2. Clean Before Storing
Always clean clothes before putting them away, especially natural fibres like wool, silk and fur. Larvae are drawn to the sweat, body oils and food traces left on worn clothes – even lightly worn items – so a freshly cleaned garment is a far less appealing meal. This single habit prevents more damage than any other.
3. Use Airtight Containers or Bags
Store seasonal and rarely worn items in airtight containers or vacuum bags to seal them off from egg-laying moths. It keeps garments fresh and ready to wear, and it's especially worth doing for knitwear, suits and coats over the summer when they're sitting unused.
4. Use Natural Deterrents – as a Supplement
Cedar blocks and lavender sachets help discourage adult moths, and they're a pleasant addition to drawers and wardrobes. Just don't rely on them alone: they deter, but they won't kill eggs or larvae, so treat them as one supplementary layer alongside cleaning, sealing and monitoring – not a fix in themselves. Refresh them regularly (a light sand brings cedar back), as the scent fades over time.
5. Vacuum Regularly
Larvae love dark, undisturbed places – wardrobe floors, under beds, the edges of rooms and beneath heavy furniture. Regular, thorough vacuuming, including wool carpets and rugs (which clothes moths attack just as readily as clothing), lifts away eggs and larvae and breaks the cycle. Empty the vacuum afterwards, ideally straight into an outside bin.
6. Catch and Monitor with Moth Traps
Clothes moth traps use a pheromone to lure and catch adult males, which both tells you how active a problem is and disrupts breeding by removing males before they mate. Moth pads and hangers are the most popular choice for wardrobes and drawers – discreet, non-toxic and easy to refresh. Remember, though, that traps monitor and reduce the adults; they don't kill the larvae doing the damage, so use them alongside cleaning and treating, not instead of it.
7. Keep Your Wardrobe Clean
Give wardrobes and drawers a regular clean, paying attention to corners, seams and hidden spots where eggs and larvae hide. Take everything out occasionally, wipe down the surfaces, and disturb the dark, still conditions moths rely on. A pile of worn-once clothes left sitting is a common starting point, so don't let one build up.
8. Seal Gaps and Check What You Bring In
Keep storage areas well sealed and tidy – fill cracks and gaps where moths can settle undisturbed, and cut the clutter that gives larvae somewhere quiet to feed. Just as important, check anything you bring in second-hand – vintage knitwear, rugs, upholstery – before it joins your wardrobe, as this is one of the most common ways clothes moths arrive in the first place.
9. Treat Anything Affected – Freeze, Heat or Dry Clean
If items are already affected, you can kill every life stage at home:
- Freeze: seal items in a bag and freeze at around −18°C for at least two weeks (colder and longer is safer, as the eggs are hardy). Ideal for delicate knitwear and anything you can't hot-wash.
- Hot wash or heat: washing at 49°C or above for 30 minutes kills eggs, larvae and adults. Check the care label first.
- Dry clean: professional dry cleaning destroys all stages and removes the moisture and soiling larvae need – the safest route for tailoring, heavy coats and delicate wool, silk or fur.
For wool carpets, rugs and curtains that can't go in a freezer or wash, a moth killer spray labelled for clothes moths can treat the affected area – follow the label, keep it away from skin and food, and ventilate well. For a bad or spreading problem, a clothes moth control kit combines monitoring and treatment in one.
10. Stay Vigilant
Check vulnerable items regularly – especially stored woollens, suits and rugs – for small holes, threadbare patches, silken webbing or tiny larvae. Clothes moths breed quietly and year-round in heated homes, so catching them early is the difference between one ruined jumper and a wardrobe-wide problem. A trap left running gives you an early warning.
FAQs: stopping moths eating your clothes
Do clothes moths eat synthetic clothes?
Mostly no – the larvae feed on natural animal fibres such as wool, silk, fur, cashmere and feathers. They can nibble blends or soiled synthetics where sweat or food is present, but pure synthetics are largely safe.
Why do I keep getting moths even though my house is clean?
Because the larvae eat natural fibres, not dirt – a spotless home still has wool jumpers, rugs and dark, undisturbed corners. Warm, centrally heated homes also let clothes moths breed all year, so a clean house is no guarantee on its own.
What actually kills clothes moths?
Freezing (around −18°C for two weeks) or heat (hot-washing or heating to 49°C+ for 30 minutes) kills eggs, larvae and adults; dry cleaning works for delicate items. Traps catch the adults but won't kill the larvae, so they're for monitoring, not treatment.
Does freezing really work?
Yes – sealing items in a bag and freezing for at least two weeks kills every life stage, and it's a method museums use to protect textiles. The eggs are hardy, though, so don't cut the time short.
Do mothballs work, and are they legal?
Traditional mothballs (naphthalene and paradichlorobenzene) are no longer sold in the UK on health grounds. Modern alternatives exist but are for sealed storage only, and cedar and lavender are gentler deterrents that won't kill larvae. Freezing, heat and good storage do the real work.
Are clothes moths and carpet beetles the same?
No – carpet beetles cause similar-looking damage but are a different pest, and moth pheromone traps won't catch them. If you find shed larval skins or small fibrous shells rather than moths, suspect beetles and treat accordingly.
Final Word
Protecting your clothes from moths is mostly about a few good habits: clean before storing, seal what you're not wearing, vacuum the quiet corners, monitor with traps, and treat anything affected by freezing, heat or dry cleaning. Remember it's the larvae, not the moths, that do the damage – so the win is stopping eggs and larvae, not just catching the adults you happen to see.
