Small black bugs found on white tile in basement and they are usually dead and you can sweep up every day?

The small black bugs you’re encountering on your basement tiles are likely carpet beetles or possibly a type of nuisance insect like ants or spider beetles. Their presence may indicate a food source or nesting site nearby. Regular sweeping is helpful, but it's also important to identify and eliminate their source by checking for any organic material, such as crumbs or dead insects. If the problem persists, consider consulting a pest control professional for a thorough assessment.
