Clothes moths do their harm quietly and out of sight. Knowing the signs helps you catch them before a favourite jumper or a valuable rug is ruined.
The first clue is often a small, slim, buff-coloured moth walking or fluttering weakly when you open a wardrobe or lift a rug. Other signs include fine silky webbing on fabric, little tubes or cases stuck to a wall, and gritty specks of larval droppings. Often the damage is discovered months after it began, when a stored item is taken out for the winter.
Larvae favour natural animal fibres: wool, cashmere, angora, silk, fur, feathers and felt. They are also attracted to fabrics soiled with sweat, food or body oils, which makes unwashed worn clothes in the back of a cupboard especially vulnerable. Woollen carpets, rugs, upholstery, piano felts and taxidermy are also at risk, as are items in museums and collections.
Clothes moths do not bite or sting and are not known to spread disease, so the risk is to property rather than health. Some people notice skin irritation from contact with larval hairs of other fabric pests, such as carpet beetles, but this is a separate issue. The distress comes mainly from lost belongings and the effort of clearing the problem, so it pays to act while the damage is still limited to a few items.
A population that keeps returning despite washing and cleaning may be coming from somewhere you have not looked. Typical sources include an old bird or wasp nest in the loft or eaves, a dead bird or rodent in a void, a stored fur or wool item and thick dust and hair under heavy furniture. Until that source is dealt with, new moths keep appearing.
Isolate any affected items in sealed bags, wash, freeze or dry clean them as appropriate and vacuum the area thoroughly. Record where damage has been found, since it points to where the moths are breeding. If valuable or sentimental textiles are involved, such as a wedding dress or heirloom rug, talk to a specialist conservator as well as a pest technician.
Not every hole in a jumper is a moth's work. Carpet beetle larvae, which are bristly and brown, cause similar damage and are often found in the same places. Snagging, wear on elbows, and damage from silverfish, which graze on starch and sizing on fabric surfaces, can also look alike at first glance. Telling them apart matters because the control measures differ.
Look for signs specific to each pest: silk and cases suggest moths, cast bristly skins suggest carpet beetles, and ragged surface grazing with fine scales may point to silverfish. If you are unsure, keep a sample of the damaged fabric and any insects in a sealed container, and show it to the technician at the survey.

Clothes moths do not bite, sting or carry disease. The harm is to fabrics and stored belongings. Some other fabric pests can irritate skin through their hairs, so it is worth confirming what you actually have. If it keeps happening, it is worth having someone look at the building itself.
Because the larvae do the damage and they stay hidden inside fabric and crevices. A few adult moths can indicate a much larger number of larvae feeding unseen. Check stored woollens and the edges of carpets. Acting early nearly always keeps the work simpler and shorter.
Small holes in knitwear can often be darned or mended by a tailor or repairer, and some valuable textiles can be restored by a conservator. Larger areas of damage usually mean replacing the item. Getting a second opinion costs nothing when a survey is free.
