Psocids (Booklice)
Psocids, often called booklice, are tiny, soft-bodied insects that thrive in moist areas where mold and mildew can grow. They’re especially common in bathrooms that don’t have adequate ventilation, since they feed on fungi found on damp surfaces and inside hidden crevices. To discourage psocids, focus on controlling moisture by running a fan during showers or keeping the bathroom door open afterward to circulate air. Regular cleaning with a mild disinfectant also helps remove the mold these insects rely on. If you notice persistent patches of mildew, tackle them promptly so psocids don’t have a reliable food source.
