Re: carpet/clothes moths!do they really eat our clothes?-how to ID them

Clothes moths primarily attack animal materials such as wool, hair, 
feathers, silk and furs.   This is also true of most carpet beetles, 
although some will eat cereals as well.  Synthetics and cotton are almost 
never attacked.  Silverfish will nibble on plant fibers (including paper) 
although they seem to prefer glue or starch (thus starched clothing will 
often be attacked).  Some tropical book lice may be a problem and termites 
will eat plant material, if their colony has contact with it.
