Do paper manufacturers have to battle book lice in their plants? Is it possible to bring home book lice with newly purchased cardstock? The reason I ask is that I just purchased cardstock from another source (nothing to do with your company), and happened to unwrap it outside and immediately saw book lice, so I know for a fact it wasn't from my home. It is such a mystery since when the same paper is examined inside at normal room temperatures, nothing seems wrong with it, but outside in strong sun, the book lice appear. Are the lice embedded in the paper and come out in certain conditions, or are bark lice outside in the air finding it almost right away and settling on it, and that's what I see?
I making greeting cards for a hobby and would hate to give cards with lice in them, so would love to hear your opinion. I remember some years ago making a card and seeing no lice, but when I put it in the hot car to take with me, I was shocked to see a couple book lice on it.

Hello A. Miller,

It would be rather unusual for booklice to be embedded into a new product. Booklice feed off of book binding paste and thrive in warm, humid climates which are more susceptible to mold and mildew.

Our paper mill partners, produce and store their paper in climate controlled environments which prevent the manifestation of booklice. There are always rare exceptions; however, we have not had any complaints of booklice in any of our cardstock, paper rolls or sheets.
