Someone was in the shop asking have you got anything good for moths? to which I replied no – but I have something bad for moths. Am I really irritating? I couldn’t help it. Anyway these moth balls are superior in that normally they are a ball impregnated with camphor which in time loses its smell whereas cedar wood (which these are) are cedar all the way through: if the lovely smell fades give em a light sanding and off we go again.
