Lice

What are the symptoms?

While lice infestations do not usually cause illness, there are certain signs and symptoms to look for:

  • Lice?The physical appearance of lice on the scalp, the body (pubic or other body hair), and clothing may look similar to tiny fruit flies. Lice are a rusty yellow color, and can be up to 1/8 inch (2 to 4 millimeters) in size.

  • Nits?Nits resemble tiny flower (willow) buds. Nits can be mistaken for dandruff, but unlike dandruff, they can't be easily brushed out of hair.

  • Louse droppings? Droppings look like a fine black powder and may be seen on bed linens.

Additionally, in some individuals, a lice infestation can cause itching and a rash, which is often worse behind the ears or on the back of the neck (for head lice), in genital areas (for pubic lice), or wherever lice is on the body. Small red bumps may appear where lice have bitten the skin.
