Clothes moths: protecting a cashmere and wool wardrobe

A cashmere jumper taken out of the wardrobe in November, riddled with small irregular holes: it is a familiar scene on the Côte d'Azur. Here, woollens stay packed away for months on end, often in heated or air-conditioned dressing rooms, and that is exactly when the larvae feed. Here is how to spot them, treat them without damaging your pieces and store your wardrobe properly.

Why cashmere and wool attract moths

The culprit is almost always the common clothes moth, Tineola bisselliella. The adult, a small golden-beige moth 6 to 8 mm long, does not eat: it is the larvae, white with a brown head, that feed on animal fibres (wool, cashmere, alpaca, silk, felt, fur). The female lays several dozen eggs directly on the clothes, preferably where traces of sweat, skin oils or food remain, which supplement the larvae's diet.

Heat speeds up the whole cycle. In a Monaco flat that stays mild all year, breeding never takes a winter break: in the warmth, a generation can develop in about two months, compared with sometimes more than a year in a cool interior.

Watch out for carpet beetles too, small beetles whose hairy larvae attack the same fibres. If, on the other hand, small moths are flying around the kitchen, they are more likely pantry moths, which do not damage clothing.

The signs of an infestation

The clothes moth shuns light and flies little: you will rarely see one in the middle of the living room. Inspect instead:

• the hidden areas of garments: under the collar, at the armpits and cuffs, in folds and seams;
• silk threads, small tunnels or cases clinging to the fibres;
• a fine granular powder the colour of the fabric: this is larval droppings, or frass;
• the back of drawers, the skirting boards of the dressing room, the underside of wool rugs and clothes that are rarely worn.

A pheromone trap in the dressing room catches males and gives you early warning, but it does not protect your jumpers: it reaches neither the females, nor the eggs, nor the larvae.

What to do right away

1. Isolate affected items in sealed bags so as not to spread the eggs.
2. Empty and vacuum the wardrobe thoroughly: corners, shelves, rails, skirting boards, under the furniture, then throw the vacuum bag away outside.
3. Clean each garment according to its care label: professional dry cleaning or a delicate wash.
4. Freeze fragile pieces: in an airtight bag, for one to two weeks at -18 °C, then let them return to room temperature without opening the bag, to avoid condensation.
5. Brush and air your woollens in daylight: brushing dislodges eggs and young larvae.

What not to do

• Rely solely on lavender or cedar: at best they deter adult moths a little, but they kill neither eggs nor larvae, and their effect fades quickly.
• Spray a household insecticide directly on cashmere: you risk stains and residues against the skin, without reaching the larvae hidden in nooks and crannies.

Storing your wardrobe well on the Riviera

The warm season is long here. To make sure your woollens come out intact in the autumn:

• clean everything before storing it, even a piece worn only once;
• keep each precious piece in a zipped garment bag or an airtight box rather than in cardboard;
• choose a dry, dark place that is as cool as possible, never a damp cellar or an overheated loft;
• inspect and shake out your jumpers every four to six weeks: moths love anything that is never disturbed;
• keep an eye on the rugs, throws, cushions and felt items around the house too: a forgotten source can reinfest a clean wardrobe.

If your clothes travel between several homes or spend time aboard a yacht, check suitcases and garment bags when you return: this is how moths move from one dressing room to another. Our advice on seasonal cashmere storage complements these rules.

When to call in a professional

If new holes appear despite cleaning, if the traps catch moths week after week, or if the infestation also affects fitted carpets, rugs and armchairs, the source is often outside the wardrobe: a rug under a bed, the carpet in a dressing room, a bird's nest under the roof. Fashion boutiques and hotels, with their stock and their drapes, are permanently exposed.

Monaco Pest Solutions starts with a free on-site audit: species identification, and a search for the source and the entry points. The action plan follows our graduated treatment method: mechanical measures first, then biological ones, and targeted chemical treatment of the room only if necessary, using approved products applied by Certibiocide-certified technicians. The intervention is discreet, and the report with photos is waiting for you in your client area. Our textile moths page details the insect's life cycle.
