I am a great fan of organic, herbal solutions for moths, but after my favourite jumper was savaged by moths I decided enough was enough. - this was despite using sack fulls of lavender and cedar blocks.
These moth balls are great! just days after using these ,not one single moth has been sighted in or around my wardrobe.
The smell is quite strong, but reminds me of my childhood, so I am willing to bare with it, knowing that the chemical filled little balls are going to save my precious knitwear, silks and cottons!
