Abstract
This paper briefly reviews the activity of clothes moths and carpet beetles and methods of protecting woollen materials against them It describes the properties of Mitin FF and DDT and their effects on various stages of the insects.
A minute amount of Mitin‐treated wool suffices to kill moth larvae and newly‐hatched carpet beetle larvae. It repels older carpet beetle larvae, which find it unpalatable.
DDT kills adult clothes moths slowly by contact. It rapidly destroys newly‐hatched larvae, probably by contact alone, whereas death of older larvae is possibly due to combined contact and stomach poisoning. It repels and adversely affects half‐grown larvae of carpet beetles.
