Head Lice

If your child returns home from school or an overnight with friends and begins to scratch his scalp because of head lice, there is no need to panic. While head lice can spread, they won’t carry any disease and they don’t mean that you or your children are unclean in any way.

What Are Head Lice?

Head lice are wingless, parasitic insects. They dwell on people’s heads and consume their blood. An adult louse is around the size of a sesame seed, and their eggs which are even smaller are called nits, and are about the size of a knot of thread. Nits and lice are the simplest to detect behind the ears and at the neckline.

Lice are very contagious. Sharing personal belongings like hairbrushes or hats or having close contact can put you at risk for catching lice. Children between the ages of three to eleven get lice most often. Getting lice has nothing to do with personal hygiene and they do not spread disease.

What Are the Signs of Head Lice?

If you’ve never had any experience with lice before and are wondering how to tell if you have lice, don’t worry, it is actually not difficult. There are some signs that you can look for that will alert you to the problem.

1. Lice Eggs

The eggs are tiny tan, yellow or brown dots before they hatch. The nits are laid on the shafts of hair close to the scalp where is warm. They look a bit like dandruff and can’t be removed by shaking them or brushing them off. After one to two weeks, the eggs will hatch and the shell will remains clear or white, staying attached firmly to the shaft of hair.

2. Adult Lice

No larger than a sesame seed, the adult is a brown or grayish-white. Nymphs will be smaller and turn into adults about one to two weeks after hatching. Most lice will feed many times a day, andthey can live as long as two days off the scalp.

3. Scratching

Scratching and itching will follow the bites of the lice. The itching won’t always start immediately, however, as it depends on how sensitive the child’s skin is to the lice. Sometimes it can take weeks before they start itching. The children could, however, complain of things tickling or moving around on their heads.

4. Red Bumps

Some children might have mild irritation, while others will have a bothersome rash. The excessive scratching can lead to a bacterial infection, causing swollen lymph glands and tender, red skin which might ooze and have crusting. Your doctor might in this case treat the infection with an oral antibiotic.

How to Prevent Reinfestation of Head Lice

There are some simple steps that you can take to get rid of lice and their eggs, plus help to prevent a reinfestation.

  • Anything that can’t be washed should be dry cleaned, such as stuffed animals. You can also put them in airtight bags for three days or more.
  • Vacuum any upholstered furniture or carpets in your home and car, then throw away the bag of the vacuum.
  • Soak any items for your hair like barrettes, combs, headbands, hair ties and brushes in rubbing alcohol or shampoo that is medicated for one hour. You can wash them as well in hot water or just get new ones.

Since lice are pretty easily passed from one person to another in the same home, infested family members and bedmates will need treatment as well to prevent the lice from returning.
