Brooke Borel, author of the forthcoming book Suck: The Tale of the Bed Bug, has also responded to Saint Louis’s article. She points out that Saint Young is outright wrong in declaring that bedbugs have only just “discovered a new way to hitchhike” through books. “This is an ancient pest, and it has been doing its thing for at least thousands of years. Probably far, far longer.” She also reiterates what entomologists have been telling me over the past two days. The risk is low. “You aren’t very likely to pick up bed bugs in these types of public spaces. The bugs are far more highly concentrated in residences, where they can breed and multiply in close proximity to their food source.”
