Louse

Natural Habitat

Typically found on a host organism (human or animal hair/clothing) or in nesting/sleeping areas.

Diet & Feeding

Obligate parasites that feed exclusively on the blood of their host.

Behavior Patterns

They are wingless, crawling insects that move between hosts via direct contact or shared items like brushes, hats, or bedding. They lay eggs (nits) that glue to hair shafts or clothing fibers.

Risks & Benefits

Risks include intense itching, skin irritation, and secondary bacterial infections from scratching. Some species can transmit diseases like epidemic typhus. There are no ecological benefits to humans.
