Head lice (Pediculus humanus capitis) are wingless insects that live on the human scalp and feed on blood. They lay eggs (called nits) near the base of hair shafts, typically around the nape of the neck and behind the ears. While lice don’t carry disease, their bites cause itching, irritation, and discomfort — not to mention social stigma and missed school days. Lice spread through direct head-to-head contact and — less commonly — by sharing hats, brushes, headphones, or pillows. Children are particularly susceptible due to their frequent and close interactions.[read more]
