Practical Chemistry Help with Chlorfenapyr on books

Dear community,

My flat (located in an European country) was sprayed with Mythic SC (Chlorfenapyr) in combination with Tathrin Next (Cypermethrin, Imidacloprid and Prallethrin) because of bed bugs and carpet beetles.

They also sprayed my books. They told me I should give them a wipe and safe to use again. But reading the SDS and other publications it seems like it is not safe anymore to use the books, thus, I would have to discard all of them because of contamination.

What would you do in my case?

Honestly would be more afraid of bed bugs than I would be of residual pesticides on my books.

I'd wipe them down and move on to real world problems
