How can I exterminate black widows in a library?

I am scared to bug bomb because of the rare books but all the storage boxes are full of spiders so there's no moving them. Is there a way to fumigate that does not endanger the books? If they weren't Widows and Recluse I'd just dump and sweep them out but not dying is preferable.
