Tips for Detecting Head Lice
Identifying whether or not your child has a case of lice can be difficult. You don’t want to subject him or her to a lice treatment and removal if it’s not necessary. Consider having your child screened by a medical professional or lice technician to get an accurate diagnosis. The technicians at Lice Treatment Center® are available around-the-clock and can come to your location within a few hours.
When determining a case of lice, you’ll need to look for three forms of the insect: nits, nymphs, and mature adults. Nits are lice eggs that get cemented to hair shafts somewhere within the first half inch from the scalp. They are extremely difficult to see and sometimes get mistaken for dandruff or residue from hair styling products. Nits can only be removed by sliding each one down the hair shaft between fingernails or with tweezers.
If not removed, nits hatch into nymphs or baby lice in about a week. Nymphs look like smaller versions of adult lice (with six legs and no wings) and are reddish in color. It takes from nine to 12 days for nymphs to grow into adult lice – which, at full maturity, are about the size of sesame seeds. The color of mature lice is generally grayish-white, but they can sometimes look darker.
Be aware that adult lice travel quickly, anywhere from two to 12 inches per minute. They don’t hop or fly, so they spread by crawling from head to head. Mature lice can live for 30 days on a head. If they don’t have a human host, however, the insects will die within one or two days. Only mature female lice lay eggs – up to about 125 eggs during a lifespan (or from four to 10 eggs per day).
Nits Signal Lice Infestation
Nits are lice eggs. They are extremely small, oval in shape, and get firmly glued by female lice to the hair strands of infected individuals. Nits can be found on the first half inch of hair shafts close to the roots – most commonly at the nape of the neck and behind the ears. Nits may be yellow or white in color, although they sometimes blend with darker hair colors.
It takes about eight or nine days for lice eggs to hatch. After hatching, the remaining shell looks white or clear and stays firmly attached to the hair shaft. This is when it's easiest to spot lice, as the hair is growing longer and the egg shell is moving away from the scalp.
The medical term for a head lice infestation is pediculosis humanus capitis. While anyone who has hair can get lice, contracting the condition is much more common among school-age children. Pediculosis is the second most common communicable disease affecting school children after the common cold.
Lice spread by literally crawling from one head to another or when infected individuals share clothing items (hats and scarves) or grooming tools, such as combs or brushes. Getting hair lice has nothing to do with how clean one’s living environment is or how well a person attends to personal hygiene. Routine screening for lice and early detection are the best and only prevention. Pesticides should not be used to prevent head lice.
How to Check for Lice
When attempting to check for head lice, use a bright light (direct sunlight is best) and a magnifying visor. Separate the individual’s hair into sections and begin by checking the crown of the head. Then check the nape of the neck and around the ears. Look for red scabs caused by scratching, actual nits, and lice that will be crawling through the hair or sucking blood on the scalp. If you find something that you think might be a lice egg or nit, try removing it with your fingers. If it comes off easily, it’s not likely a lice egg or nit.
