When thinking about allergens in our homes, we may think to dust our bookshelves including the tops of our books. But, did you know that potent allergens can actually lurk in and even be fed by books?

Cockroach allergy affects up to 60 percent of urban residents who suffer from asthma, according to the Allergy and Asthma Foundation of America. But what do cockroaches have to do with books? As many know, cockroaches are hardy survivors who can go for a long time without eating and who feed on unlikely food sources – including the glue of your books' bindings! According to NaturalSciences.org, "Cockroaches live where humans dwell. They prefer warm, undisturbed areas with high humidity near a source of water—under sinks, around toilets, and in showers. They eat human food and also non-food items like soap, toothpaste, and glue."

Mildew is another allergen that can hide in your books, contributing to your total allergen load and triggering attacks upon exposure. Because mildew can spread from book to book, we recommend getting rid of any books that smell musty or have visible signs of mold.

Knowing about hidden allergens and routing them out of your living environment makes your home allergy-friendly and helps you and your family breathe better. Stay tuned for more tips.
