Dr Ted Edwards, former Australian National Insect Collection (ANIC) Lepidopterist; Honorary Fellow CSIRO's Australian National Insect Collection: 
 "Traditional moth balls are also effective,
but they contain toxic chemicals,
so instead consider using natural alternatives
like sachets of dried lavender... bay leaves."
