Reading in bed, once considered a relatively safe pastime, is now seen by some as a riskier proposition. That’s because bedbugs have discovered a new way to hitchhike in and out of beds: library books. It turns out that tiny bedbugs and their eggs can hide in the spines of hardcover books. The bugs crawl out at night to feed, find a new home in a headboard, and soon readers are enjoying not only plot twists but post-bite welts.

Ebooks are safer.
