Moths and what helps

Sep 12, 2026

Short answer: Moths go for animal fibres and for stains of sweat and food. Clean clothes in a tight box carry almost no risk, and cedar only works in a closed space where the scent is concentrated.

What moths are after

Moths lay eggs where the larvae can find food. They go mainly for animal fibres, but also for stains of sweat, food and skin oil in the fabric. So the material alone does not decide whether a garment is at risk. How clean it is matters at least as much when it is stored for a long time.

Moths go for stains

A clean garment is far less interesting to a moth. Even small stains you cannot see may be enough to attract them. So wash everything before it is packed away for the next season. That includes pieces you have only worn once, because skin oil and sweat are in the fabric anyway.

A tight box is the best protection

If the moth cannot get in, it cannot lay eggs. A plastic box with a lid that seals all the way round keeps them out. Then the contents carry no risk, as long as they were clean when packed. A pair of men's bamboo joggers can lie folded in such a box all season.

Cedar only works when shut in

In an open wardrobe the scent fades and has no effect. Cedar and similar scents only work when shut inside a small space where the scent builds up. So put a block in the tight box or a closed drawer, not on an open shelf. And remember that the scent fades over time.

Clear out the wardrobe regularly

Moths thrive where it is dark and quiet and nobody disturbs them. A wardrobe that is cleared and vacuumed now and then is a poor place for them. Take the clothes out, shake them and vacuum the corners and shelves. It does not take long and removes the spots where eggs can hide.

Air and light keep them away

Moths dislike light and movement. Clothes that are worn and washed regularly are rarely a problem. It is the pieces that hang untouched for months that are most at risk. Take them out now and then, shake them and let them hang in the air. It is a simple habit that makes a difference.

If the damage is done

If you find small holes or webbing, empty the wardrobe straight away. Wash what can be washed and vacuum thoroughly, including cracks and corners. Then pack the clean clothes in tight boxes. Light pieces like a bamboo tank top for men wash quickly and dry fully.

Small pieces count too

Socks and other small items are often forgotten during a clear out. Yet they can also carry stains that attract moths. Gather them in a small bag or box and wash them before storing. If you need new ones, have a look at bamboo socks for men and women.
