In the UK there are over 4 main species of moth that cause damage to textiles like carpets, clothes, and soft furnishings.
All textile moth species are after a protein called keratin which is a protein found in all natural fibers. Finding the source to the infestation is key, it might not be where you are actually noticing them or where they have caused damage so far. We find in most cases there is an underlying problem that has not yet been addressed. For example old carpets stored in attic spaces can be the source of moth infestations.
