Les poux sont extrêmement agiles et rapides pour se déplacer sur les cheveux. Leurs pinces leur permettent de solidement s'agripper aux cheuveux.

Les poux se nourrissent exclusivement de sang humain, toutes les 3 ou 4 heures. Ce sont les morsures des poux lorsqu'ils se nourrissent qui provoquent les démangeaisons et l'envie de se gratter la tête.
