The Nature of the Beast

The head louse, latin name Pediculus humanus capitis,
is a globally prevalent blood-sucking ectoparasite. It feeds on human blood several times a day. The female lays its eggs (nits) and cements them onto the hair shaft. The immature louse moults three times after hatching from the egg and is ready to mate 11 to 18 hours after the last moult. Eggs are laid 11 to 18 hours after mating.


Itching is a reaction to louse saliva and faeces.
Secondary infection of scratches may occur. Long-term infestation can lead to an impetigo-like bacterial infection or low-grade flu-like symptoms in extreme cases.

Catching lice

This takes place by head-to-head contact, during play
or when working or reading together.


This will often follow treatment unless you synchronize treatment with everyone else!
