To get rid of clothes moths, empty the wardrobe completely, vacuum every surface including the corners and the underside of shelves, wash or freeze affected garments to kill eggs and larvae, wipe the interior down, and then store clean clothing with cedar or lavender in a well ventilated unit. Pheromone traps tell you whether adults are still flying. The insects doing the damage are the larvae, not the moths you see, so surface cleaning alone will not end an infestation.
Two species cause most problems in British homes: the common clothes moth and the case bearing clothes moth. Both are small, buff coloured and reluctant to fly toward light, which is how they differ from the larger moths that come in through an open window. Those are harmless to clothing.
Before treating anything, look for the evidence.
Irregular holes in wool, cashmere, silk or anything with animal fibre. Larvae feed on keratin, so cotton and synthetics are usually untouched unless blended.
Fine silky webbing or small tubular cases stuck to fabric, often in folds, cuffs and under collars.
Gritty specks that look like sand or fine dust, which are the droppings.
Small cream coloured larvae, a few millimetres long, in dark undisturbed places.
Adults that scuttle rather than fly, usually in the corners of the wardrobe or along skirting boards.
If the holes are neat and round, the cause is more likely wear or a snag. Clothes moth damage is characteristically ragged and concentrated where the fabric has been in contact with skin oils.
Half measures fail. Take every item out and put it in one place where you can inspect it. Check under collars, inside cuffs, along waistbands and in the folds of anything stored folded.
Separate what you find into three groups: clearly infested, natural fibre and worth treating as a precaution, and synthetic or cotton items with no sign of damage.
Bag the infested items straight away so larvae cannot move to anything else while you work. This is also a good moment to be honest about what you no longer wear, since a wardrobe carrying half a household’s unused clothing is far harder to keep clean. Our guidance on paring things back sits alongside our range of modern wardrobes UK sale units, where interior layout makes a real difference to how easily a space can be inspected.
Vacuum first, with a crevice tool. Concentrate on the joints between panels, the shelf pin holes, the rail sockets, the corners of the base and any gap behind a drawer. Larvae hide in crevices, not in the open.
Empty the vacuum outside immediately. Bagless cylinders should be washed out.
Wipe every internal surface with warm soapy water, then dry it completely. Pay attention to the underside of shelves, which almost everyone misses.
Vacuum the room too. Skirting boards, the carpet under and around the wardrobe, and any carpet edges near the unit. Larvae feed on wool carpet as readily as wool jumpers, and an untreated carpet edge will reinfest a clean wardrobe within weeks.
Take out any loose drawers and check behind them. If the unit has a plinth or a recess at the base, vacuum inside it.
Heat and cold both kill every life stage. Choose according to the garment.
Washing at 60 degrees kills eggs and larvae outright. Most cotton and many blends take this comfortably.
For wool and cashmere that cannot be washed hot, freezing works. Seal the item in a bag, remove as much air as possible, and freeze for at least 72 hours. A second freeze after a few days at room temperature gives extra certainty.
Professional cleaning kills all stages and is the right route for tailoring, coats and anything structured.
A tumble dryer on a warm cycle for thirty minutes deals with items that cannot be washed hot but can take heat. Check the label first.
Brush every treated garment before it goes back. Brushing removes eggs mechanically and is the traditional method for a reason.
Once everything is clean, keep it that way.
Cedar blocks and rings discourage adults from laying. Their effect fades as the oils dry out, so sand them lightly every few months to refresh the surface.
Lavender sachets work similarly and need replacing once the scent has gone. Neither cedar nor lavender kills larvae already present, so they are prevention rather than cure.
Pheromone traps attract male moths and give you a reliable indication of whether adults are still active. Put one in the wardrobe and check it weekly. A trap that stays empty for a month is good evidence the problem is over.
Breathable garment bags protect stored woollens well. Avoid plastic, which traps moisture and invites a different problem.
Moths are drawn to soiled fabric, because skin oils, perspiration and food traces are what the larvae feed on most readily. Clean wool is far less attractive to them.
Store everything clean, never worn once and put away. Fold knitwear rather than hanging it, and keep it in a closed box or a breathable bag with a cedar block.
Choose a cool, dry, well ventilated place. A cold spare room is better than a warm airing cupboard. Where a bedroom is short on capacity, a lidded ottoman or a blanket box handles seasonal woollens neatly and keeps them separate from everyday clothing. There are practical options among our modern blanket boxes UK sale pieces for exactly this purpose.
Check stored items once mid season. Ten minutes of inspection prevents the discovery of a ruined jumper in October.
Most recurrences have one of four causes.
The carpet was not treated. Wool carpet under and behind furniture is the most common reservoir in British homes.
A single garment was missed. One folded scarf at the back of a shelf is enough.
Items came in already infested, often second hand woollens or stored boxes from a loft.
The wardrobe is too full to inspect and clean properly, so the corners never get reached.
That last point is worth taking seriously. A unit packed to capacity is a habitat. If the answer is more storage rather than fewer clothes, the wider range at Furniture in Fashion covers everything from tall single units to wide four door pieces, and pairing a wardrobe with drawers usually makes both easier to keep clean. A piece from our modern chest of drawers UK sale range takes folded knitwear out of the wardrobe entirely, which also makes seasonal checks quicker.
Vacuum inside the wardrobe every couple of months, and behind it twice a year. Rotate stored items so nothing sits undisturbed for a full year, since darkness and stillness are exactly what larvae need.
Air the wardrobe when you air the room. Moths dislike disturbance and light, and simply opening the doors regularly makes a space less hospitable.
Keep one pheromone trap running permanently in a house that has had an infestation. It is the cheapest early warning available.
Vintage knitwear, charity shop coats and inherited blankets are among the most common routes an infestation takes into a home. Treat everything before it goes near a wardrobe.
Keep the item sealed in a bag from the moment it enters the house. Wash it at the highest temperature the label allows, or freeze it for 72 hours if it cannot be washed hot. Only then should it join the rest of your clothing.
The same applies to boxes brought down from a loft or collected from storage. Open them outdoors or in a garage rather than in the bedroom, and inspect the contents in daylight before deciding what comes inside.
Antique and second hand furniture deserves the same caution. Vacuum every crevice of a used chest or wardrobe thoroughly before putting clothing in it, paying attention to the runners, the joints and the space behind any drawer. Where a piece is beyond that kind of rescue, the wider selection across our modern bedroom furniture UK sale range offers a clean start.
Clothes moth larvae feed on any animal fibre, so the wardrobe is rarely the only site. Wool rugs, felt underlay, upholstered seat pads, sheepskin, taxidermy and even the felt inside a piano are all viable food.
Check under furniture that is never moved, since larvae favour dark undisturbed places. The strip of carpet beneath a wardrobe or a heavy chest is the classic hiding place.
Treat any wool carpet in the affected room at the same time as the wardrobe. Vacuuming the edges thoroughly, including along the gripper rods, removes the reservoir that otherwise reinfests everything you have just cleaned.
Traditional moth balls have largely been withdrawn and the modern equivalents smell strongly and taint fabric. Thorough cleaning, correct storage and cedar or lavender deterrents are a better approach.
The larvae. Adult clothes moths do not feed on fabric at all, so seeing adults matters only because it means eggs are being laid somewhere nearby.
Yes, if the item is sealed and left for at least 72 hours at freezer temperature. Repeating the process after a few days at room temperature adds certainty for valuable knitwear.
Larvae feed on animal fibres such as wool, cashmere, silk and feather. Pure cotton and synthetics are generally safe, though blends containing wool are vulnerable and soiled fabric is targeted first.
Allow a full life cycle. After a thorough clean and treatment, expect to see nothing new within a few weeks, but keep a pheromone trap in place for two to three months before declaring it over.
