Species of Liposcelis sometimes occur in large numbers in stored products, houses, ships and merchandise stores; many species are of world-wide occurrence, the traditional 'booklouse' usually being one or other species of this genus. They cause damage to insect collections and may occur in houses in sufficient numbers to be a nuisance. Members of this family are commonly found under bark.
