Do I need to be concerned about bugs (moths, etc.)?

No. We apply a minor amount of boric acid (less than 1% by weight), which is all-natural and non-toxic, as an insect repellent. In addition, it is often the lanolin that attracts pests. Our wool comes from New Zealand where the most advanced scouring (cleaning) techniques in the world are employed to ensure a consistent, clean fiber that is provided for our process.
