Case Bearing Clothes Moth


The case bearing moth is a silvery grey/brown moth. Adults can reach a wingspan of 16 millimetres. The forewings are spotted – one large spot and several other smaller ones. The forewings are plain. Both sets of wings have a fringed edge.

Habitat / Diet

This moth is a pest when it makes its home in your home – in the larvae stage. These pests feed on your clothing, furniture and carpets. They also consume cobwebs and wallpaper!


Egg – larvae – pupae – moth

After mating, the female case bearing moth will lay around 50 eggs over around a week. These will then hatch into the larvae - which is the destructive stage as they can stay this way for three months feeding on your textiles, causing much damage. When they are sufficiently provided, and at the optimum size, they will begin to pupate. This involves spinning a cocoon. Metamorphosis can take from 9-19 days when they will discard their cocoon and become moths. The case bearing moth itself only lives for a matter of days – long enough to reproduce and start the cycle again.

Identification of an Infestation

It is easier to identify with their fringed wings. Another sign is seeing the small cases that emerge from – about the size and appearance of a grain of rice. The other obvious sign is damage to your possessions.

Generally seen from around June to September, they can be prevalent all year round due to our centrally heated homes.


This is one for the professionals. Finding the source of the eggs and larvae source can be difficult, and if they are not all treated, you are right back at square one.

This pest will be treated with insecticides, and so it is best to leave the preparation, treatment and aftercare to us.
