Hi. I have been finding these tiny bugs in our new condo. I find them on baseboards, windowsills and around our electric breaker box. They are very small (1-4 millimeters, I would say), and are easier to spot with a flashlight. I have found about 50 of them over a 4 week period.
You are being concerned unnecessarily because of this Booklouse, probably a member of the genus Lipocelis based on this BugGuide image. According to the North Carolina State University Department of Entomology: “Booklice feed primarily on microscopic fungi and mold. Therefore, they are most often found in damp, dark areas. Such places may include basements, crawlspaces, kitchens, leaky plumbing, unvented storage areas, and around over-watered houseplants. They may also show up in recently built homes where they entered during construction and were enclosed in a wall after siding and sheetrock were installed. … Booklice are often associated with old books or other papers that are stored in damp conditions. These conditions promote the growth of mold or fungi on the pastes and glues of book bindings. They may also be found in food goods stored in humid conditions that support mold development. While their presence can cause great annoyance, they rarely cause significant damage to items.”
