Head lice are tiny, six-legged insects that spend their entire lives on human heads. They are usually spread from child to child when sharing clothing, combs, or brushes. While there are various treatments available for head lice, including over-the-counter and prescription medications, some people have suggested putting a plastic bag on one's head to suffocate the lice. This method is controversial, with some sources advising against it, while others claim it to be effective when combined with the use of petroleum jelly.

What You'll Learn
It is unsafe to put a plastic bag on a child's head
Firstly, it is important to understand that head lice are tiny, six-legged insects that spend their entire lives on human heads. They are usually spread from child to child through shared clothing, combs, or brushes. To prevent the spread of head lice, it is recommended to avoid sharing personal care items such as hats, scarves, combs, and brushes. It is also important to regularly check your child's hair, especially during the school year and when there is a lice outbreak at school.
If your child is affected by head lice, there are safe and effective treatment options available. You can use over-the-counter or prescription medications, such as pediculicides, which are specifically designed to treat head lice. These medications can kill both lice and their eggs, also known as nits, and following the provided instructions is crucial. It is also recommended to treat all household members and close contacts simultaneously to prevent re-infestation.
Additionally, you can implement extra measures to manage lice, such as machine-washing and drying clothing, bedding, and other items used by the affected person in hot water and high heat. Soaking combs and brushes in hot water is also effective. Vacuuming floors and furniture, especially where the infested person has been, can help remove any remaining lice or eggs.
While some sources suggest using a plastic bag to suffocate lice, this method is not recommended by experts. It is essential to prioritize the safety and well-being of your child. Instead, follow the treatment guidelines provided by healthcare professionals and use medications specifically designed to treat head lice effectively and safely.

Seal items that can't be washed in a plastic bag for two weeks
Head lice are tiny, six-legged insects that spend their entire lives on human heads. They are usually spread from person to person when sharing clothing, combs, or brushes. Lice can also crawl onto nearby items such as bedding, towels, and hats. While lice need human blood to survive and don't live long after falling off the body, it is still important to clean any items that may have been contaminated.
The Centers for Disease Control and Prevention (CDC) recommends the following steps to avoid re-infestation by lice:
- Machine wash and dry clothes, bedding, and items used by the infested person in the two days before treatment.
- Wash items in hot water (at least 130°F or 54°C) and dry them in a dryer using the hot setting for at least 15-20 minutes.
- If you can't wash or dry clean items, seal them in a plastic bag for two weeks.
- Soak combs, brushes, and other hair care items in hot water (at least 130°F or 54°C) for 5–10 minutes. You can also soak them in rubbing alcohol for one hour or use a lice shampoo or rinse.
- Vacuum the floor and furniture, especially where the infested person sat or lay.
It is important to note that fumigation and insecticide sprays are not recommended, as they can be toxic if inhaled or absorbed through the skin.
Therefore, if you are unable to wash certain items, sealing them in a plastic bag for two weeks is an effective way to kill any remaining lice or nits.

Lice can be killed by smothering, dehydration, or medication
Lice are tiny insects that feed on blood from the human scalp. They can be killed by smothering, dehydration, or medication.
Smothering
Lice can be smothered using occlusive treatments such as mayonnaise, olive oil, margarine, or butter. However, the CDC states that there is no scientific evidence that these methods are effective. Another way to smother lice is by using wet combing.
Dehydration
Lice can be killed by dehydration using hot air. This method is offered by some professional lice treatment centers and involves using a machine that dries out and kills lice and their eggs. It is important to note that attempting to do this with a hairdryer at home may not be effective and could spread lice to other people.
Medication
Lice can be killed using over-the-counter or prescription medications called pediculicides. Some medications kill both lice and eggs, while others only kill lice, requiring a second treatment to target newly hatched lice. It is important to follow the instructions provided with the medication and to consult a healthcare provider if necessary.

Wash items in hot water to prevent lice infestation
Head lice are tiny, six-legged insects that spend their entire lives on human heads. Nits, or lice eggs, are often found near the scalp, as they require the warmth from the scalp to survive. Lice infestations are particularly common among pre-school and elementary-school-age children.
To prevent the transmission of lice or re-infestation, it is important to wash the affected person's personal items thoroughly. Machine-wash items in hot, soapy water, at a temperature of at least 130°F (54.4°C). The high temperature is crucial for killing lice and their eggs. Wash bedding, clothing, stuffed animals, towels, washcloths, blankets, and sleeping bags.
For items that cannot be machine-washed, consider dry-cleaning or placing them in a tightly sealed plastic bag for at least two weeks. Any lice or nits on these items will die within two days without a human scalp to feed on.
Delicate items that cannot be exposed to hot water or high heat should be soaked in warm water with laundry detergent for several hours to kill the lice. Then, wash them on a delicate cycle in the machine and let them air-dry.
In addition to washing items, it is important to vacuum floors and furniture, especially in areas where the affected person frequently sits, plays, or sleeps. Combs and brushes should be soaked in hot water for at least 5-10 minutes.

Combing is a way to loosen lice eggs
Head lice are tiny, six-legged insects that spend their entire lives on human heads. Nits are the eggs of lice, and they resemble dandruff but do not flake off when touched. While there are medications available to treat head lice, combing is another way to loosen and remove lice eggs. This method is called "bug busting" or "wet combing." It involves combing wet hair with a special fine-toothed comb to pick out lice and their eggs. These combs are supplied with some head lice shampoos, or you can use a regular comb with very fine teeth, spaced no more than 0.3 mm (0.01 inch) apart.
- Begin by combing through wet hair with an ordinary comb to remove any knots or tangles.
- Apply conditioner or olive oil to make it easier for the fine-toothed comb to glide through the hair.
- Comb through every section of the hair, pulling the comb from the scalp to the ends.
- Rinse off any lice from the comb and down the sink as you find them.
- Continue working through the hair until you have combed through each section at least twice, flushing away any lice or eggs you find.
- After each treatment, check the hair and remove any remaining lice or eggs every 2-3 days for the next 2-3 weeks to catch any new lice that have hatched.
It is important to note that the effectiveness of combing in removing lice and eggs may depend on how consistently and thoroughly it is performed. While combing can be a useful tool, it may not be sufficient for everyone. In addition, it is crucial to never place a plastic bag on a child's head, as this is dangerous and will not effectively treat head lice. Instead, seal items that have come into contact with the affected person, such as bedding and brushes, in a plastic bag for at least two weeks to prevent the spread of lice.
