These little insects can do a lot of very costly damage to woollen carpets, woollen jumpers and even fur coats. The casemaking clothes moth will only attack animal fibre fabrics etc. unlike Silverfish that will only attack synthetic fibres. Customers should be aware that the normal silverfish treatment will not affect these casemaking moths. It is actually the larvae that does all of the damage as you can see by the pests where it emerges out of its case or cocoon, feeds and then goes back into its case. These pests are not as prevalent as in the past years as these days our garments and carpets are now more synthetic fibres compared to years ago our clothing and carpet were more woollen fibres. These casemaking moths are usually found in homes and shops where there are fabrics. The adult casemaking moths are usually around 7-10mm in length, wingspan is approx. 14 mm and brown in colour. The larvae is approx. 10mm long and are light yellow and cream in colour with a brown head. These moths spin a silk cell around itself whilst feeding and they are usually not seen to the naked eye sometimes as the case is the same colour of the interwoven fibres of the material that it has been feeding on. They move about with there head and legs extending out of their case. See photo of a Casemaking Clothes Moth.
