Inanimate fiber (likely synthetic or lint)

Found in household dust, clothing, upholstery, and on skin surfaces

Does not eat; inanimate

Stationary unless moved by air currents, static electricity, or physical contact; does not exhibit biological life cycles

No biological risk. Fibers like these are common components of household lint. They are often mistaken for parasites (as seen in Delusional Parasitosis) but reflect textile shedding rather than insect activity.
