Can Head Lice and Nits Live in Pillows and Sheets

Did you know that lice are one of the top 3 reasons why kids miss school?

When a family is affected with lice, one of the first reactions is to change all the sheets and bedding. Dealing with lice is stressful primarily because nobody seems to want to talk about it. Understanding how lice live can make anxiety go away. It can also help us find a solution in dealing with them.

Head lice are very common. Children between ages 3 and 13 are perhaps the most susceptible. Outbreaks are not dangerous but they are contagious and very annoying. Contrary to popular belief, getting lice is not because you don’t wash your hair. Clean hair can get lice too. The good news is that lice can’t fly, jump or swim so getting treatment is easier than you think.

The Life of a Louse

Louse is the singular form of lice and their life starts as an egg or nit. Female lice lay around half a dozen eggs per day. This tiny speck is yellowish in colour and is around 1mm long. They have a glue-like surface which makes them hard to remove. Nits hatch after 7 to 10 days and become immature nymphs and become adults after 10 days.

Just like us, lice need to eat several times a day. This is why they draw blood from the scalp by piercing it. Lice are parasites and can’t live without a human host for more than 24 hours. It is important to know this because there is misconception on how lice are spread and how to respond appropriately.

Lice move by crawling. They cannot fly, jump or swim. They are spread by direct contact with the hair of an infected person. Anybody who has come in head-to-head contact with a person with lice has a good chance of getting it.

Since head lice travel by crawling, they don’t fall on pillows, sheets, stuffed toys and other furniture unless they are attached to a hair that has fallen. The same is true with nits. They need human warmth to fully gestate. Nits that are removed or fall even if they are attached to a hair die before they hatch. This means that lice can’t live on your sheets and pillows for long. The human head is their happy place.

Do I Need to Change My Pillows and Sheets?

Relax because you don’t need to fumigate the house or throw everything inside the washing machine. If your child or family member has head lice you just need to wash their clothes, bedding and towels. Use normal setting for washing but use the hottest drying cycle possible. Lice can’t live underwater for long and the high temperature is usually enough to kill any nits.

Stuffed toys don’t need to be washed. You just need to stick them in the dryer in high heat for 20 minutes. It is important to think where lice might have fallen. Hats, backpacks and head rest of your car should be checked and cleaned. You can try vacuuming these items or using a homemade essential oil spray.

You also need to clean brushes, combs, head bands and other hair accessories. Hair is usually found in these items and it’s always better to clean them than risk a re-infestation. Brushes can’t be machine washed but they can be cleaned. Start by removing all the hair that’s stuck to the brush or comb. Throw them in the sink that’s filled with hot soapy water. Generally, lice can be killed in water around 55°C. Keep them there for at least 30 minutes. Rinse, dry and then use as usual. Other items that can’t be laundered or cleaned this way can be dry cleaned or sealed in a garbage bag for 2 weeks.

Once you’ve washed all the bedding, you need to clean around the person’s room some more. Even though lice can’t live long without a human host, many people cringe at the thought of having them crawl around the room. To avoid this, you need to decontaminate surrounding areas. Start by vacuuming the carpet. Lice can’t live there so this is for your peace of mind. Vacuum the mattresses too.

There are bedding sprays found in the market to kill lice but you can use a homemade one too. You can mix 2 cups of water with 10 drops of essential oil such tea tree, lavender, rosemary and peppermint in a spray bottle. Spray on bedding and other surfaces. Lice don’t like the smell so they are a natural but very fragrant repellent.

Once everything is cleaned to your liking, you can put on clean bedding and pillow cases.

Lice Prevention

Lice are spread through human contact. The sooner they are detected the better. Quick action on your part can prevent them from spreading in your home.

Here are some tips to follow:

  • Screen your child once a week. The first sign of lice is usually the nits and head scratching.
  • Check them thoroughly especially after returning from camp, holiday break or school. These are the places and events where breakouts occur frequently.
  • Promote lice screening at school. This can help limit or prevent outbreaks.

What to Do During Infestation

If an outbreak occurs at school or at home again, follow the cleaning steps directed above. The other thing to do is to treat the person with head lice. There are many treatments available in department stores. There are shampoos, combs and other over the counter remedies. To prevent infestation for the whole family, it is better that everybody uses an anti-lice shampoo until the outbreak is contained.

After each treatment check the hair by using a nit comb. This will decrease the chance of a re-infestation. Continue to check for 2 to 3 weeks to ensure that all lice and nits are dead.

Take Away

Head lice cannot live long if they fall off and cannot feed. You don’t need to spend a lot of time cleaning or buying all the anti-lice products you can lay your hands on.

Lice are nuisance that many children have to suffer through. However, since they can’t jump or fly there’s no need to panic and start replacing pillows and mattresses. Take comfort in the fact that they can’t live long without a human host. Getting rid of them is just a matter of throwing the bedding in the washing machine.
