Interesting Facts About Head Lice

Head lice are a common insect infestation of the human head hair. They lay eggs close to the scalp and move freely around the head without losing their grip, due to their long front legs that are strong and powerful, perfect for gripping to human hair.

Head lice live for up to six weeks and can multiple rapidly, moving from human host to human host colonizing as they go. It only takes one female head louse to start an infestation as they can lay up to two hundred and ten eggs in their lifetime.

In their infancy the head louse, known during this period as a nymph goes through metamorphoses three times, and every time the nymph will shed its exoskeleton to promote its own growth.

The most likely source of an infestation is from children between the ages of four and eleven year of age, they will normally catch an infestation from school or after school clubs and pass the infestation on to their family or other friends.

Due to over a million years of evolving to live on human hair, the head louse is every bit adaptable to what humans use as treatment or how humans run their everyday lives.
