Tiny little clothing moths love to fly around and lay their eggs in wool, cotton, natural fibre clothing in dark places like drawers and wardrobes.  The lavae then start eating their way through the fibres leaving holes or destroying garments.  Instead of using chemicals, a natural defense is to place some freshly cut cedar wood pieces in with the clothes.  Humans like the faint smell of Cedar, but it  seems to persuade moths to fly off and try elsewhere.
