The best way I've found to get rid of moths is to use cedar chips in the bottom of drawers, wardrobes, cupboards etc. You can even use them as a pot - pourri without anyone commenting adversely (if you care a sh** about what friends, family and neighbours think, anyway !). They need to be refreshed from time to time with cedar oil to keep things active, and the smell is wonderful. Sprigs of dried lavender may also be used if you find cedar too strong or masculine.
