Since I only use natural fibers and I don't buy yarn as most are dyed and dipped into pesticides to keep the moths away... well many people might find they are not allergic to wool or lanolin but to the chemicals used at the processing mills while dying.
I simply buy few planks of red cedar, I put those in the closets and use lavender sachets in the drawers, you can always use some lavender essential oil to refresh the sachets. The bugs won't bug you and won't feast on your wool, better be safe than sorry, this is very simple and natural no harmful chemicals.
It's not very expensive or complicate and it's working great.
