<\/p>\n

A hole in a wool sweater is usually found in October, months after the damage was done. Clothes moths work quietly, in the dark, on garments nobody has touched since spring. Understanding what is actually eating the wool, and what the small moth flying around the room is doing, changes the whole approach to stopping it.<\/p>\n

\"Wool<\/figure>\n

The adult moth is not the one eating your clothes<\/h2>\n

Adult clothes moths do not feed. They have no working mouthparts, they live a few weeks, and their entire job is to mate and lay eggs.<\/p>\n

All of the damage is done by the larvae, which are small cream coloured grubs a few millimetres long that hatch on the fabric and eat their way outward from where they started.<\/p>\n

This changes the approach completely. Swatting the adult you saw across the room achieves nothing, because by then the eggs are already laid, in the dark, on something you own.<\/p>\n

It also means the number of adults you see tells you very little. One female lays dozens of eggs, sometimes a couple of hundred, and the ones doing the damage are never in the air.<\/p>\n

The target is eggs and larvae, and both of those are on fabric rather than flying around, which is why every effective control in this guide is something you do to the clothing and the room.<\/p>\n

What the larvae actually eat<\/h2>\n

They eat keratin, the protein that animal fibre is made of. Wool, cashmere, mohair, alpaca, silk, feathers, fur and felt are all on the menu.<\/p>\n

Cotton, linen, viscose, polyester, nylon and acrylic contain no keratin at all, so a clean garment made of any of them is not food and gets left alone.<\/p>\n

Blends still count. A sock that is eighty percent wool and twenty percent nylon is a meal, and larvae will chew straight through the synthetic to reach what they want.<\/p>\n

The list is wider than clothing. Wool rugs, felt, upholstery stuffing, down filling, feather trim, hairbrushes and the hair and fluff at the back of a wardrobe all support them.<\/p>\n

This is why damage from clothes moths is so concentrated. It shows up on the wool half of the wardrobe and nowhere else, which is often the first clue about what you are dealing with.<\/p>\n

Why soiled fabric is the real target<\/h2>\n

Clean wool is a poor food source. Larvae need moisture and traces of salt and other nutrients that pure fibre does not give them.<\/p>\n

Body oil, sweat, hair product, food and drink residue all supply exactly that, which is why a worn garment is a far better target than the identical unworn one hanging next to it.<\/p>\n

It explains where the holes appear. Cuffs, collars, underarms and the front of a sweater take the damage, while the back panel of the same garment is untouched.<\/p>\n

It also explains the odd cases. A cotton shirt stored with a food mark on it can be damaged even though cotton itself is not food, because the larvae are feeding on what is on the fabric.<\/p>\n

The practical version is short. Clothes moths are drawn to what is on the wool at least as much as to the wool, and that single fact is what makes the cleaning step so effective.<\/p>\n

How to tell you have clothes moths<\/h2>\n

The holes are irregular. Ragged soft edges, uneven shapes, often several close together in one area rather than a single clean puncture.<\/p>\n

Look for fine silky webbing, either threads running across the surface or a small tunnel of it tucked into a fold. Some species build a portable case that looks like a grain of rice or a speck of grit stuck to the fabric.<\/p>\n

There is usually frass as well, gritty specks the same colour as the garment, because the larvae take on the colour of whatever they have been eating.<\/p>\n

You may find a shed skin, thin and translucent and easy to mistake for lint.<\/p>\n

The adults themselves are small, buff or straw coloured, a bit over half a centimetre, and they scuttle into folds rather than flying at a lamp. A moth that flies to a light in the evening is almost certainly a different species and not your problem.<\/p>\n

Where they actually live<\/h2>\n

Dark, still and undisturbed. That is the whole preference, and every hiding place follows from it.<\/p>\n

The back of a wardrobe, the bottom of a drawer, a suitcase, a storage box, the pockets of a coat that has not been worn in a year.<\/p>\n

Under and behind furniture on a wool rug, along the carpet edge under a heavy sofa, and in the pile of a rug that a bed sits on.<\/p>\n

They avoid light, moving air and disturbance, which is exactly why the clothes you wear every week never have holes and the sweater you love and save always does.<\/p>\n

When you find damage, work outward from it. Whatever is nearest and least disturbed is usually where the rest of the population is sitting.<\/p>\n

Washing everything before you store it<\/h2>\n

This is the single most effective control there is, and it costs nothing beyond a normal laundry day.<\/p>\n

Wash or dry clean every animal fibre garment before it goes into storage, including things worn once and things that look perfectly clean. What you are removing is the invisible oil and salt, not the visible dirt.<\/p>\n

For washable wool, that means cool water, a detergent made for wool, as little agitation as the machine allows, and drying flat rather than hanging.<\/p>\n

Temperature is not what matters at this step. Removing the residue is what matters, so a cool careful wash that rinses properly beats a hot one that does not.<\/p>\n

Never store an unworn garment alongside a worn one. One soiled sweater is enough to bring clothes moths into a box of otherwise clean wool and give them everything they need.<\/p>\n

Heat and cold for anything that cannot be washed<\/h2>\n

Some things cannot go through water at all, and for those the answer is temperature.<\/p>\n

Heat is the simpler option. Twenty to thirty minutes in a dryer on a medium setting will finish off clothes moths at both the egg and larval stage on anything that can take the heat, and it works on things that are technically clean but suspect.<\/p>\n

Cold works too, but only if it is done properly. Seal the item in a bag, freeze it for several days, take it out and let it come back to room temperature for a day, then freeze it again. The swing is what does the job, because a slow steady chill lets larvae harden off and survive.<\/p>\n

Sunlight and a vigorous shake outdoors will clear a rug or a heavy coat of a surprising amount, since larvae abandon anything bright and moving.<\/p>\n

Steam works well along carpet edges and on upholstery seams where a wash is not possible and a vacuum cannot reach far enough in.<\/p>\n

Airtight storage, and why cardboard boxes fail<\/h2>\n

Once an item is clean, the aim is a barrier that nothing can get through in either direction.<\/p>\n

Cardboard is not a barrier. Larvae get in through the corners and the flap gaps, and cardboard holds moisture as well, so it fails twice. A garment bag open at the bottom fails for the same reason.<\/p>\n

What works is a rigid plastic box with a gasket lid, a heavy zip closed bag, or a vacuum bag for bulky knitwear. All of them keep adults out and keep anything already inside from spreading.<\/p>\n

Store dry. Sealing wool away while it is even slightly damp trades one problem for another, so make sure everything is fully dry before the lid goes on.<\/p>\n

Put a note on the box with the date and open it once partway through the season. A quick look costs a minute and turns a ruined collection into a single damaged item.<\/p>\n

What cedar and lavender genuinely do<\/h2>\n

They repel rather than kill. Aromatic cedar and lavender can discourage an adult from settling and laying in a confined space, and that is the honest limit of it.<\/p>\n

Neither does anything at all to larvae already in the fabric or to eggs already laid. If damage is happening, a cedar block will not stop it.<\/p>\n

Cedar loses its strength as the oil in the surface dries out, usually within months. Sanding a block lightly brings some of it back. An old cedar chest with no smell left is doing nothing but holding your clothes.<\/p>\n

Lavender behaves the same way and needs replacing every season to have any effect at all.<\/p>\n

Used inside a sealed box after everything has been cleaned, they are a reasonable extra layer. Used instead of cleaning and sealing, they are not a control, and treating them as one is the most common way people lose a wardrobe to clothes moths.<\/p>\n

Vacuuming as a control<\/h2>\n

Clothes moths live on surfaces a vacuum can reach, which makes vacuuming one of the more useful things you can do and one of the most neglected.<\/p>\n

Do the wardrobe floor, the corners, the bottoms of drawers, under the bed and the carpet edges under heavy furniture. Move the furniture rather than working around it.<\/p>\n

Use the narrow tool along seams, skirting and the join between carpet and wall, since that is where the debris they feed on collects.<\/p>\n

Empty the vacuum outside immediately afterwards and take the bag out of the house. Otherwise you have simply relocated the problem.<\/p>\n

Do this while the wardrobe is empty rather than after you have refilled it. The order matters more than the effort.<\/p>\n

When you find an active infestation<\/h2>\n

Take everything out of the affected wardrobe or drawer. All of it, rather than only the damaged pieces, because eggs sit on things that look perfectly fine.<\/p>\n

Sort into animal fibre and everything else. Every wool, silk, cashmere, feather or fur item gets washed, dry cleaned, heat treated or frozen before it goes anywhere near clean storage.<\/p>\n

Vacuum the empty space thoroughly, then wipe down the shelves, the rail and the corners with a damp cloth.<\/p>\n

Put nothing back until it has been treated. A wardrobe cleaned halfway is recolonised within weeks, and you will conclude that nothing works when in fact the untreated half did the reinfesting.<\/p>\n

Pheromone traps are worth having, but as a monitor rather than a cure. They catch males and tell you whether the problem is still live, which is how you know when you are actually finished.<\/p>\n

Expect to go around twice. Eggs sitting in a crack will hatch after you think you have finished, so plan a repeat vacuum a few weeks later.<\/p>\n

Carpet beetles cause similar damage<\/h2>\n

If the pattern does not quite match, the other common culprit is the carpet beetle, and it is worth telling them apart before you spend a weekend on the wrong problem.<\/p>\n

Beetle larvae are bristly and carrot shaped rather than smooth, and they leave shed skins that look like tiny hollow versions of themselves.<\/p>\n

The damage tends to be grazed and thinned across an area rather than punched through in distinct holes, and it often appears where a rug meets a wall.<\/p>\n

The adults are small rounded beetles usually found at windows, because unlike clothes moths they are drawn to light and they come in from outside on flowers and through open windows.<\/p>\n

The good news is that the control is the same. Clean, seal, vacuum and heat treat, and both problems go away together.<\/p>\n

A seasonal routine that keeps clothes moths out<\/h2>\n

In spring, at the end of the wool season, wash or clean everything before it is put away, treat anything that cannot be washed with heat or cold, and seal it in something rigid.<\/p>\n

In the middle of the warm months, open one box and look. Five minutes of checking is what turns a disaster into an inconvenience.<\/p>\n

In autumn, when the wool comes back out, shake each item outdoors, hang it in moving air for a day, and look it over in good light before it goes on the rail.<\/p>\n

Through the cold months, rotate what you wear. A garment in regular use is disturbed, aired and handled, and it is a poor target for that reason alone.<\/p>\n

Once a year, empty and vacuum the wardrobe itself. Everything else on this list depends on that space being clean to begin with.<\/p>\n

The Chicago part<\/h2>\n

The shape of the year here is what creates the problem. Winter is long and genuinely cold, so wool is in heavy use for months on end. Then the whole lot goes away for an equally long warm season, sealed up and undisturbed. Six months of dark still storage is the ideal condition for clothes moths, and almost every household in the city has that cycle built into its calendar whether it thinks about it or not.<\/p>\n

The humid summer matters as much as the cold winter does. Larvae need moisture, and warm damp air keeps stored fabric from ever drying out fully, especially in a basement or an interior closet with no air movement. A box that went away in April holding slightly damp knitwear is in far worse shape by August than the same box would be in a dry climate.<\/p>\n

The heating season creates the opposite trap. Indoor air goes very dry for months while storage spaces that are not heated stay damp, so anything kept in the least used corner of the building sits at a different humidity from the rooms people live in. Wool put away in a cold back closet is not being stored in the same conditions as the rest of the house.<\/p>\n

The practical adjustment is timing. Do the storage cleaning in spring, before the humid months rather than after them, and get everything sealed while the air is still dry. Wool that goes into a box clean and dry in April will come out in October the way it went in.<\/p>\n

Where to wash wool before it goes away for the season<\/h2>\n

The storage wash is the one that decides everything, and it needs enough water to carry body oil out of the fibre rather than move it around inside the garment.<\/p>\n

The machines at our self-service laundry on West Diversey Avenue<\/a> run a much larger volume of water than a home unit on a gentle cycle, which is what actually rinses sweat and skin oil out of a wool garment before it spends six months in a sealed box.<\/p>\n

Our machines and the store are cleaned daily.<\/p>\n

Nou wash-dry-fold service<\/a> covers the everyday laundry.<\/p>\n

For general guidance, The American Cleaning Institute publishes a fabric care guide<\/a> that is a useful cross-check.<\/p>\n

The short version<\/h2>\n

Adult clothes moths do not eat anything, so the target is always the larvae and the eggs, and both are on the fabric rather than in the air. They eat keratin, meaning wool, cashmere, silk, feathers and fur, and they are drawn to garments carrying body oil, sweat or food residue, which is why holes appear at cuffs and collars. Wash or clean everything before storage, since that one step removes most of what attracts them. Freeze or heat treat what cannot be washed, then seal it in rigid plastic rather than cardboard. Cedar and lavender repel and do not kill. Vacuum the empty wardrobe and empty the machine outdoors.<\/p>\n
