Body Louse (Nit or Nymph stage)

Exclusively lives in human clothing and bedding, moving to the skin only to feed. Unlike head lice, they lay their eggs (nits) in the seams of clothing.

Hematophagous (feeds exclusively on human blood)

They are obligate parasites that cling to fibers in clothing. They crawl; they cannot jump or fly. Infestations are typically spread through close physical contact or direct contact with infested clothing or bedding.

Risks: Significant health risk. Their bites cause severe itching (pruritus) which can lead to secondary skin infections. More importantly, they are vectors for diseases such as epidemic typhus, trench fever, and louse-borne relapsing fever. Benefit: None to humans or standard ecosystems.
