Is it safe to use baking soda to kill possible roaches/any bug that may be in kid's books?

I am moving out of a roach infested house in two days- I have not seen ANY roaches on or near the books, but the bookshelf is right next to the fridge, so I'm kind of paranoid they might have gotten into mine and my kid's books. I have read that baking soda will kill roaches, so if I put the books in ziploc bags with baking soda and then cleaned them off with wipes or something after we unpack- if it would be safe. I assume baking soda isn't toxic to people, is it? Provided they're not eating spoonfuls or something.
