The holes in these woolen shawls illustrate what moths can
do to a natural-fiber product.
Textiles are an excellent food source for microbes and insects.
Sizing (a process which gives cloth more body), many materials
used in the making of the cloth, and soiled spots or dirt on
the garment all help attract insects. The most common pests are
the clothes moth, silverfish, and carpet beetle. Some damage
is easy to detect but some organisms literally eat their way
from the inside out; this causes the development of weak areas
which are not easily observed until the garment is handled.
