Books, papers and the like will give birth to bookworms with small flesh color if they are kept for a long time. Is there any way to get rid of them? Better avoid them. Thank you.

There are basically no moths in the newly bought books, and the bugs you see may just be "passing by". Generally speaking, moths don't like the smell of fresh ink and won't eat books until the smell disappears. Insect books can be put in sealed plastic bags and some mothballs. All insects can be completely killed in a few days.
