Boric acid and pest control

I would like info about pest control (insects) using boric acid for
paper based material (library collections). The Truly Nolen is now
operating in Portugal and they use boric acid to eliminate
silverfish (Ctenolepisma Longicaudata/Escherich, 1905, the most
common Lepismatidae at library/archives/museum in south europe ).
I've asked them if they had worked for libraries/archives in USA but
I guess not. I would appreciate any suggestions,
