For me the question is were the holes because the bugs were getting in or out? Did some get in then lay eggs?

If I think some of my wool has an infestation, I will put it in a bag and in the freezer for a week or so to kill the bugs. I think insects can survive up to 3 days in the freezer but no more (I am sure there are some exceptions).

Thanks for the reminder to protect our seeds, and to see something positive out of these learning experiences.
