Body Louse Egg (Nit)

Natural Habitat

Found on fibers of clothing, bedding, and fabric in close contact with human skin.

Diet & Feeding

Eggs do not feed; adult body lice feed exclusively on human blood.

Behavior Patterns

Nits are glued to fabric fibers using a cement-like substance. They typically hatch in 1-2 weeks if kept warm by human body heat.

Risks & Benefits

High risk; body lice can transmit serious bacterial diseases such as louse-borne typhus, trench fever, and epidemic relapsing fever. They often thrive in crowded, unsanitary living conditions.
