Vacuuming carpets and furniture upholstery is another component of the treatment process for head lice. A bright light and a magnifying glass are useful tools to aid in the detection and diagnostic process. Adults are about the size and shape of a sesame seed with six legs and the same beige to grayish-white coloration. It's difficult to prevent the spread of head lice among children in child care facilities and schools because there is so much close contact.

If a child has lice, a parent or caregiver should notify the school or daycare. They cannot fly or jump, but they can crawl from one head to another. This can happen when people’s strands of hair meet during close contact. Here's all you need to know about what head lice and nits look like. Lice lay nits on the side of the hair strand, as opposed to wrapping around the hair. The analogy that best describes nit location on a hair strand is a flower with a long stem and a single leaf growing from the stem.

What Lice Eggs (Nits) Look Like
Head lice live exclusively in human hair and rarely come off the head unless physically removed. They feed on human blood several times a day, but fortunately do not spread diseases. Head lice are no respecter of persons, and anybody can get head lice, no matter their age, race, or cleanliness. As we just discussed, a common misunderstanding is that nits are white. Nits are colored differently depending on your own hair color, and whether the nits are hatched or unhatched.
Regular Lice Eggs vs. Super Lice Eggs
The idea of bugs crawling in your hair or your child’s hair can be unnerving and upsetting. Contrary to folk wisdom, lice aren’t the result of poor hygiene, and they don’t carry diseases. Then, you’ll want to tackle your home, as lice can live up to two days on inanimate objects.
Check Close to the Scalp for Nits
Lice are tiny parasitic insects found on your head, pubic hair, and body. Even though they are slightly different, they all can attempt to live on your body and feed on your blood to survive. In people with allergies, a history of scalp infections, or an injured scalp, it may not be safe to use over-the-counter lice treatments. Even if successful in killing all the adult lice, it is crucial to remove all the eggs, as they will hatch into nymphs that become adults. If the medicine seems to be working, wait a few days to wash your hair, and keep combing each day for a couple of weeks to ensure you remove all of the lice. You may need to treat again in a week to kill surviving lice that hatched after the first round of treatment.
Bites from live lice, which are a result of the bugs feeding on human blood, sometimes cause an itchy rash on the scalp. Lice on a comb are minuscule insects typically with a brownish hue. Additionally, there may be nits, resembling small oval yellowish or white specks firmly attached to hair shafts.
White and Brown Nits in Hair: What Lice Egg Color Means
Nits take roughly 8-9 days to hatch and aren’t a problem until the lice emerge. In addition to treating the infected person, you can take additional steps to kill lice that may have fallen off. For example, wash bedding and clothing in hot water and dry them on high heat. You can keep items that can't be washed in sealed plastic bags for two weeks, during which time any live lice on the items should die.
Head lice are spread primarily by direct head-to-head contact. So the risk of spreading head lice is greatest among children who play or go to school together. In the United States, cases of head lice most often occur in children in preschool through elementary school. See a health care provider before you begin treatment if you suspect that you or your child has head lice. Your or your child's health care provider can confirm that head lice are present.
If you still don’t find lice but see brown nits within 1 cm of the scalp, they may be live eggs. Consult a doctor about treatment and wet combing for nit removal. Because of this, finding nits alone doesn’t always mean there’s an active lice infestation. In a study from 2001, researchers carefully examined a group of school-aged children who had nits alone and found only 18% developed active head lice.
“You can sometimes see live lice running around,” Dr. Hamilton says. It seems like you’d know if you or a loved one has lice. But, if you’ve never dealt with the creepy scalp crawlers in the past, it can be hard to know what you’re looking for.
The casings left behind by nits that hatch are typically translucent. Being able to identify head lice will also help you make an informed choice about treatment. Usually, you only need to treat your child with a lice shampoo when you see live lice. If you only see lice eggs and no live lice, you just need to carefully remove them.
The glue is what gives the impression that the nit has a tail. You will always find this tail if you’re dealing with lice eggs. Lice treatments and home remedies do not kill lice eggs. Lice eggs that have already hatched will be transparent/translucent in color and usually appear white in the hair. These nits no longer have lice inside of them, so they are not a threat. Unhatched or “viable” nits have color to them, they begin golden brown and then become darker the closer they are to hatching.
