Moths love wool and your winter woolen wear is a smorgasboard for these flying pests. The Clothing Moth (Tineola bisselliella) is a species of moths from the Tineidae moth family. The caterpillar (larva) of this moth is recognized as a serious pest. It can derive nourishment not only from clothing – in particular wool – and also, like most moth caterpillars, from many other sources.
Contrary to what most people believe, adult clothing moths do not eat or cause any damage to clothing or fabric. It is the larvae which are solely responsible for this, spending their entire time eating and foraging for food.
Both adults and larvae prefer low light conditions. Whereas most other moths are drawn to light, clothing moths seem to prefer dim or dark areas. If larvae find themselves in a well-lit room, they will try to relocate under furniture or carpet edges. Hand made rugs are a favorite because it is easy for them to crawl underneath and do their damage from below. They will also crawl under moldings at the edges of rooms in search of darkened areas which hold good food.
