I have been recomended to treat the natural wool with borax to prevent insects, i don´t know if it works with moths too, but I haven´t heard about any problems.

On the subject of sheeps wool insulation, I've been doing some research
because I wanted to know why it was being produced commercially at such a
cost when we could get fleeces so cheaply. The main reason I keep coming
back to is that untreated sheeps wool is completely tasty to moths. I have
spoken to several people now who have used it and say the moths just
completely eat it up, even if it's in a sealed space. The main cost during
processing is in blending in an anti-moth mineral and making it stay in the
wool and not leach out over time. So, I would say to beware of the Moth!
Best wishes
