I did not say that the only thing clothes moths like to eat is human skin/sweat. They like clean clothes too, as long as they are fibres like wool, silk and cashmere of animal/insect origin.
This is because they eat keratin. Keratin is a protein of animal/insect origin. But they will attack other fibres too, like cotton, if there is keratin there from other sources e.g. human skin cells.
By the way, clothes in laundry baskets tend to go into the wash soon after. Washing (provided it’s at a sufficiently high temperature) does kill moth larvae.
One of the things leading to the current explosion in clothes moths in the uk, is the increasing use of low temperature washing. A 60C wash will kill moth larvae, a 30C wash won’t. Fabrics unsuitable for a hot wash (wool, cashmere, silk) are more properly treated by an alternative method, such a freezing or dry cleaning.
High standards of cleanliness, proper storage and cleaning of clothing, regular vacuuming of crevices in rooms and furniture and cleaning out drawers/wardrobes etc are all good practices that can prevent or manage moth infestations.
Moths aren’t very prevalent in some areas of the UK. If you live in one of those areas, you could be very lax on a lot of these things and be fine.
Other areas, you could be pretty strict and still be unlucky- the centre of Edinburgh for example is a particular moth hotspot (partly due to all the beautiful buildings, which have horsehair in the wall plaster as that was the building method then- as the old plaster crumbles, it falls into wall cavities and the moths take hold).
When I lived in the centre of Edinburgh, we kept all wool/silk/cashmere items in a second freezer with drawers, in order to minimize dry cleaning and washing. We also kept the number of items of clothing we had to a bare minimum, and everything we had was in regular rotation use.
