You can see head lice easily although they are pretty small. An adult louse is sort of brown and is about the size of a sesame seed. Once they hatch, louse nymphs reach adulthood in about a week. Lice need to feed about every four or six hours and can live independent of the scalp for as much as three days.

After lice bite, you get the urge to itch or scratch, although the itchiness won't necessarily begin right away. This is dependent upon how sensitive your skin is to head lice. You can see lice by parting the hair a little bit at a time. When you are looking for lice, you should check the scalp, the area behind the ears, and near the nape of the subject's neck.

It is helpful to search for lice using a magnifying glass, lice comb and bright light. It is, however, tough to find a nymph or adult louse. A lot of times, there aren't loads of of them but they're able to move fast so it becomes difficult to find them.

Head lice are extremely contagious especially within group settings. They can spread rapidly from person to person. Even though they cannot fly or jump, they have special claws that allow them to creep and tenaciously stick to hair. The sharing of clothes, hats, bed linens, hairbrushes, and combs helps spread them along.

You can kill lice and lice eggs with lice treatment medications. The itch won't stop for several days. You should redo any treatment in eight or ten days to ensure every egg or nit has been destroyed to make sure they never recur another time.

Body lice are a common problem, world wide. These tiny bugs are capable of transmitting diseases, like typhus, relapsing fever, and trench fever. More than anything, being stricken with body lice is embarrassing for the sufferer and very itchy for them. Body lice are more common during the winter months because people tend to dress in layers, which creates a warm and moist breeding ground for lice growth. Generally speaking, body lice are limited to underdeveloped countries with poor sanitation and serious overcrowding.
