Can I somehow treat wood with active silverfish colony?

Help

Long story short, my grandfather was a lifelong wood worker but passed away a few months ago. A few years before he passed we moved stuff into a storage space. This included some beautiful live edge slabs and rough cut boards of oak, cedar, and walnut. I was going to use the wood to build some shelves out of and use the live edge stuff for a bar in my home. When we went to take it out of storage I noticed a lot of piles of dust and silverfish in between the oak boards. There was no indication that they were in the cedar and walnut but they were stacked adjacent to each other with edges touching.

Is this wood still usable? If so how do i make sure that I kill the infestation so I don’t bring them into the house? I would really like to save what I can but don’t want to destroy my home in the process.
