Likely booklouse (psocid)

Humid indoor locations such as cupboards, stored paper, cardboard, bedding, and moldy materials. The image is too blurry for species-level confirmation.

Feeds mainly on mold, fungal spores, algae, and microscopic organic residues rather than fabric or blood.

Usually crawls slowly and prefers darkness and high humidity; populations increase where moisture supports mold. They may disperse through stored goods and household materials.

Harmless to people and pets, and they do not bite or transmit disease. Large numbers indicate excess moisture or mold and can damage paper products, but they also consume fungal material.
