Human Head Louse
Pediculus humanus capitis
- Order & Family
- Order: Psocodea / Family: Pediculidae
- Size
- 2.0 mm to 3.0 mm (approximately the size of a sesame seed).
Natural Habitat
The scalp and hair of humans, primarily near the ears and the nape of the neck.
Diet & Feeding
Strictly hematophagous; they feed on human blood several times a day.
Behavior Patterns
They are wingless and cannot jump or fly; they move by crawling. They lay eggs (nits) firmly attached to hair shafts near the scalp.
Risks & Benefits
They cause intense itching (pediculosis) and scalp irritation due to an allergic reaction to their saliva. They do not spread disease but can lead to secondary skin infections from scratching.
