Head lice cases are on the rise, igniting an epidemic in the UK.

Young children in daycares, crèches, and elementary schools often have a higher risk of head lice infestations. 🏫

These tiny critters thrive on human blood and pose a real challenge to remove.

Lice multiply quickly, are highly resilient, and spread through direct contact. 🪳

Our article has all you need to know about lice and how to get rid of them.

How long can lice live on bedding without a host?

Lice have a limited survival rate without their primary food source: blood.

They can't live on your bedding for more than two to four days.

Still, if you suspect a lice invasion, washing sheets and pillowcases at a scorching 54.4°C (130°F) is wise. 🔥

How long do lice eggs live on bedding?

Lice have the potential to find their way onto your bedding, pillows, and mattresses and lay eggs.

Lice in bed
Lice can get onto your bedding.

However, they can't thrive and hatch in such environments.

This is because they depend heavily on body heat and blood for survival.

Nymphs (baby lice) have a limited life span without food and will die within a week.

💡 Did you know: There is a key difference between nits and lice. Head lice are small insects that live on the scalp, and nits are their oval-shaped eggs that can typically be found on the hair shaft.

Unlike fleas and bed bugs, lice don't have the tendency to venture far from their human host.

Instead, they remain close rather than returning sporadically to feed.

What types of lice can be found in bedding?

There are 3 types of lice that can live on humans and may spread through your bedding:

  • Head lice - Lives on the person’s head and cause itchiness. They spread through hair-to-hair contact. Very common in school-aged children.
  • Body lice - A sesame-sized insect that lives on the body. The infected person may be living in crowded or unhygienic conditions. Severe symptoms include sores and infections.
  • Pubic lice - Usually found in pubic hair around the groin, but can also be found on the chest, armpit, face, or even eyelashes. Pubic lice is typically spread through sexual contact and may need to be treated with medicated creams or shampoos.

Lice need to feed on blood to survive and cannot survive on bedding for more than a few days. 💀

Washing bedding at a high temperature is an effective way to kill all types of lice.

Below, we’ll dive into all you need to know about head lice infestations and how to get rid of them. 👇

What are head lice?

Head lice and nits are small insects that live on human hair and feed off blood from the scalp.

What do head lice look like?

Lice are typically two to four millimetres long, sporting a greyish hue that can turn reddish-black after feeding.

Head lice
Head lice are two to four millimetres long.

Equipped with a head, two antennae, and three pairs of legs ending in pincers, they're adept at clinging to hair.

Nits are a distinctive white and cling near the top of hair strands. Unlike dandruff, they don't easily fall off, thanks to the sticky substance from female lice. Females lay between four to ten eggs daily.

What do lice eat?

Lice feed solely on blood, using a unique biting and sucking mechanism. 🩸

A single lice may bite up to 4 times a day, which can cause the host immense itching.

How do head lice spread?

Lice and their eggs (known as nits) are primarily spread through close contact. 👫

Children having a pillow fight
Children are prone to head lice.

Just one child with lice can sometimes be the catalyst for an entire group getting infested through head-to-head contact.

Kids with long hair are especially vulnerable, as lice can easily latch onto their hair using their specialised pincers. 🦟

Also, sharing items like headphones, hairbrushes, hats, or hair ties can lead to transmission.

Signs of head lice

Lice infestations, or pediculosis, typically result in an itchy scalp.

An itchy head is a symptom of head lice.

Frequent head-scratching is one of the most noticeable physical symptoms of head lice.

🔍 Myth buster: A common misconception is that head lice are a result of poor hygiene. But lice can survive for up to six hours underwater, so regularly washing your hair is not an effective way to combat lice.

With increased lice reports from schools, it's vital to check the scalp on a regular basis. 🔎

Checking for lice
Check your child’s hair regularly.

We recommend checking for lice with a comb in natural daylight, as adult lice despise light and are easier to spot. 💡

Scalp pediculosis

Scalp pediculosis is the most widespread parasitic disease in the world.

This condition arises from a severe lice infestation.

However, anyone can fall victim to scalp pediculosis. 😣

Over-itching can lead to skin lesions, especially behind the ears and neck.

The World Health Organisation revealed that pediculosis impacts several billion people around the world and is often predominant in schoolgoers. 🌍

It’s key to be vigilant before the symptoms of lice become severe.

How to get rid of lice overnight

Lice in the household can be frustrating. 😠

To get rid of lice, you must understand their life cycle and ensure all lice and nits are completely removed from the home.

But the following tips can help you get rid of lice quickly:

  • Don't share clothing items like hats or scrunchies
  • Assign individual pillowcases to each family member
  • Regularly check your child's hair, especially after school or camps
  • Comb the hair with olive, lavender, or tea tree oil

We’ll go into more detail below. 👇

Avoid sharing products

You should ensure each family member uses their own towels, pillows, and bedding.

Do not share brushes, scarves or hats and ensure the child is not sharing these items at school, particularly when there is a lice infestation.

Use over-the-counter products

The best head lice treatment can be bought in the form of anti-lice shampoos containing permethrin or dimethicone 4% lotion. 💊

Removing lice from hair
Use anti-lice shampoos.

Often, these shampoos remove the lice but not the nits.

Running a comb through the hair after using anti-lice shampoo is an important additional step to kill lice and nits.

Repeat 7-10 days later to ensure complete eradication.

Wash bedding and accessories

After treatment, you should wash all bedding and hair accessories using hot water above 54.4°C (130°F). 🧼

Washing sheets
Wash bedding at a high temperature.

Non-washable items should be sealed in a plastic bag for up to two weeks to ensure complete eradication.

Try natural remedies to prevent lice

Olive oil is one of the best natural remedies for head lice.

Combining olive oil with a mixture of lavender and tea tree oil can effectively eradicate lice.

Essential oils
Lavender and tree tree oil is effective against lice.

In fact, studies show a 100% mortality rate after 30 minutes of treating lice with tea tree oil.

You should mix 3 tablespoons of olive oil with 1 tablespoon of tea tree oil and comb through your hair.

Other natural remedies such as vinegar, baking soda and mayonnaise have not proved effective enough to remove lice.

To sum up...

Lice infestations, though common, can be a source of distress for both children and parents. 😓

Regularly checking hair, machine washing clothes and bedding at high temperatures, and using lice-deterring remedies are the keystones to keeping these pesky parasites at bay.

Remember, it's not just about treating lice but preventing their return. 🚫

Frequently asked questions

  • Can lice survive a washing machine?

    Lice can survive in water for up to 6 hours but will be killed in temperatures greater than 53.5°C (128.3°F) for more than 5 minutes. 

    Therefore, we recommend washing bedding and clothes at a high temperature. 

    For items that cannot be washed, seal them in a plastic bag for a minimum of two weeks. 

  • How long can lice eggs live on sheets?

    Nits may land on bedding and pillows, but they can't thrive there due to their dependence on body heat and blood. 

    Unlike fleas and bedbugs, lice typically don't survive more than 48 hours away from their human host. 

  • Do lice stay on pillows?

    Lice do not spread around the house or on your bedding. 

    They are most commonly found on the scalp, behind the ears, near the neck and at the hairline. 

    Luckily, they can only survive for around 2 days on pillows and bedding. 

    However, you should wash your bedding after treating hair lice to ensure you remove any live lice or eggs from the home.

  • How do you know if you have lice in the bed?

    You can tell if you have lice in your bed by carefully inspecting the sheets, pillows and mattress. 

    Lice and nits are very small and will be greyish-brown or white in colour. 

    However, lice present on clothing or bed linen inevitably end up dying on these objects.

  • Do lice live on clothes?

    Lice cannot survive on clothing for long. 

    These insects live exclusively on human hair so it's unlikely they will venture very far from the head. 

    They need to be close to their food source (the scalp) to survive.
