Book lice, also known as psocids, are tiny insects commonly found in homes, especially in areas with high humidity. Despite their name, these pests aren’t true lice and don’t pose a direct threat to humans or pets. However, they can become a nuisance due to their affinity for paper products and stored food. These soft-bodied insects are often discovered in dark, damp areas such as basements, attics, and bathrooms, where they feed on mold, fungi, and other organic matter. Book lice thrive in environments where moisture is prevalent, making dehumidifying your home a crucial step in preventing their infestation.

In homes, book lice are particularly problematic in libraries, storage rooms, and pantries. They can cause damage to valuable books, papers, and even wallpaper by feeding on the paste or glue that binds them. In kitchens, they may contaminate stored foods, especially those that are improperly sealed, by feeding on the starchy materials. Controlling humidity levels and ensuring proper food storage are essential in keeping these pests at bay. Regularly cleaning and inspecting areas prone to moisture can also help prevent a book lice infestation, ensuring your home remains free from these unwanted invaders.
