Next door, Josh is the only one seemed to his business. All he feels is an itch 1, but invisible to the naked eye, a mite 2 has get to go, too. Bloated with human skin, one mite can defecate about 20 pellets every day.And judging by the state of Danny's hair, she's having a louse start to her day. It's a life with head lice. It's a myth that head lice like dirty hair. Clean hair is less likely to be greasy 3 and easier to move around, and long hair provides more places to hang on to. Head lice have six grasping legs, each with a cl* to help them stick to the hair shafts 4. There are usually fewer than a dozen lice on an infected head, but they can be a mountain of litter. The discarded shells hunderds of eggs. Female lice can survive on the same skull 5 for nearly a month and lay up to 60 eggs. And once one member of a household has lice, without treatment, everyone is at risk of invasion. These lice punch skin to feed at least once a day, draining blood for its nutrients 6, and inject s* to stop clotting 7. A young lice's transparent 8 body takes on the family colors after its first meal.
Body lice are much hard to brush aside. Human body is a hard place for body lice to live. There's nothing to grab onto, no place to hide. So instead, they take refuge in the folds and creases 9 of dirty clothes.
