Louse Nit (Empty Egg Casing) or Skin Debris

Natural Habitat

Typically found on the human scalp, attached near the base of hair shafts. However, the debris pictured is dislodged and on a fabric surface.

Diet & Feeding

Nits themselves are eggs and do not eat. Adult lice feed on human blood. Skin debris is inert.

Behavior Patterns

Nits are cemented firmly to hair shafts by the female louse. Once hatched, the empty casing (which this likely represents if biological) remains attached but appears white or translucent. This object appears to be a dislodged, possibly crushed, casing or simply a piece of dried sebum/dandruff.

Risks & Benefits

Risks: If it is a viable nit, it indicates an active lice infestation which causes itching and potential secondary infection from scratching. Benefits: None.
