Cashmere is animal hair and will need proper care to control and prevent mold and moth infestation.

Keep knitwear dry and use moth repellent as necessary.

How to Protect Your Cashmere from Insects

We have several customers a year asking us to repair damage caused by insects. There are now fewer insects in the house than in the past, so we sometimes underestimate the risks of insect damage. Still, they do exist, and insects do make holes in our precious cashmere sweaters.

Types of Insects
Many types of insects eat clothing; some major ones include clothes moths and carpet beetles.

Clothes Moths
Found worldwide, the larvae eat silk, wool, and leather. They live in nests and are active all year.

Clothes moths mainly live in houses, not in nature. Their eggs are laid in carpets and on clothing. Because they live closely with people, they will spread globally as international logistics expands.

The larvae are relatively large at about half an inch, and they have a whitish color. Usually, they create protective cases for themselves. They can eat fibers quickly.

Carpet Beetles

The carpet beetle is a drone beetle, quite small at 2 to 3 millimeters.

Its larvae are about 5 millimeters and pass the winters as hairy caterpillars. They damage natural fibers such as wool and silk. Their ecology and life cycle are not well known.

The adult bugs eat flower pollen, not fibers.

Carpet beetles can be found everywhere, and the adult bugs are especially active in spring. When you come back from taking a walk outside, brush off your clothes before entering the house.

Food on your clothes can attract more insects, so clean food off your clothes, too.


There are various types of insecticide. Please read instructions carefully and use insecticides accordingly.

Do not mix or use too many insecticides.

How to Ward Off Insects

Moth Balls
Cedar Wood

Clothes moth eggs will not hatch if steam is applied. We do use some steam during production, so it may prevent some insect damage. You might want to try it at home (but please do not press the garment or use steam for too long, as the excessive heat will damage the fibers).
