How to Clean Bedding after Lice

In this guide, we’ll explore the step-by-step process of how to clean bedding after lice, pillowcases, and blankets of these pesky parasites. From washing techniques to specialized treatments, we’ll cover everything you need to know to ensure that your bedding is free from lice and their eggs.

Additionally, we’ll discuss preventive measures to minimize the risk of future infestations and offer tips on maintaining proper hygiene practices. With the right approach and attention to detail, you can effectively clean your bedding and create a safe, lice-free environment for yourself and your family.

Importance of Thorough Cleaning

Thorough cleaning of bedding after a lice infestation is paramount not only for eliminating the present pests but also for preventing their potential return. Lice can survive off the human head for up to 48 hours, which means that bedding, pillowcases, and blankets can serve as temporary hosts, posing a risk of reinfestation.

Additionally, lice eggs, or nits, can remain viable on fabrics and hatch if not properly addressed. By ensuring a comprehensive cleaning process, you remove these threats, safeguarding the health and cleanliness of your living environment.

Beyond the removal of lice and their eggs, a thorough cleaning routine helps in reinstating a sense of wellbeing and comfort in your home, making it crucial not just for physical health but for mental peace as well.

Understanding Lice Infestation

Tackling the Cleaning of Bedding

Before tackling the cleaning of bedding after a lice infestation, it’s essential to understand what you’re dealing with. Lice are tiny, wingless parasites that feed on human blood and are most commonly found on the scalp.

They are not a result of poor hygiene but are spread easily through close personal contact or the sharing of personal items such as hats, brushes, and, yes, bedding. There are three forms of lice to be aware of: the egg (also known as a nit), the nymph, and the adult louse.

Nits are hard to see and often confused with dandruff, but they attach firmly to hair shafts. The nymph is an immature louse that hatches from the nit and matures into an adult about 7 to 10 days later. Adult lice can multiply rapidly, laying up to 10 eggs a day, which makes understanding and quickly addressing infestations critical. Recognizing the signs of lice early can significantly reduce the spread and make the cleaning process more manageable.

Types of Lice That Infest Humans

There are three main types of lice that infest humans, each preferring a different part of the body. Understanding these types is crucial for effectively treating and preventing lice infestations.

  1. Head Lice (Pediculus humanus capitis): The most common type found, especially among children. These parasites live and lay eggs on the scalp, feeding on human blood. Symptoms typically include itching and the presence of nits attached to hair strands.
  2. Body Lice (Pediculus humanus corporis): These lice live and lay eggs on clothing and bedding rather than directly on the human body. They move to the skin to feed. Body lice infestations are often associated with poor hygiene and living conditions, and they can be vectors for other diseases.
  3. Pubic Lice (Pthirus pubis), also known as crabs: These lice infest the coarse hair of the pubic region but can also be found in underarm hair, chest hair, and, occasionally, eyebrows and eyelashes. Pubic lice infestations are usually spread through sexual contact but can also be transmitted through contaminated bedding or clothing.
Lice Live and Lay Eggs on Clothing and Bedding

Each type of lice requires a specific treatment approach and meticulous cleaning of the environment, including bedding, to prevent a reoccurrence of the infestation.

Transmission and Common Symptoms of Lice Infestation

Lice infestation occurs through direct contact with an infected person or through sharing personal items and fabrics, such as bedding, hats, hair brushes, and clothing. This proximity allows the lice to move easily from one host to another, emphasizing the importance of personal hygiene and caution in shared spaces to minimize the risks.

Transmission: The primary way lice are spread includes:

  • Direct Head-to-Head Contact: Especially common among children during play at schools, sports activities, or sleepovers.
  • Sharing Personal Items: Such as combs, brushes, hats, and scarves can facilitate the transfer of lice.
  • Fabrics and Upholstery: Bedding, towels, and even furniture that have been in contact with an infested person can harbor lice and nits, awaiting a new host.
Recognizing the Symptoms of Lice Early

Common Symptoms: Recognizing the symptoms of lice early can lead to quicker treatment and less chance of widespread infestation. Typical indicators include:

  • Persistent Itching: The most noticeable symptom, caused by an allergic reaction to lice bites.
  • Red Bites or Sores: These can appear on the scalp, neck, and shoulders, often a result of scratching.
  • Visible Nits and Lice: Nits are tiny, oval-shaped, and often seen clinging to hair shafts near the scalp. Adult lice may be harder to spot due to their size and quick movement but can still be seen upon close inspection.
  • Feeling of Something Moving: A tickling sensation or the feeling of something moving in the hair.

Understanding these modes of transmission and being vigilant for symptoms can play a crucial role in early detection and treatment, ultimately reducing the impact and spread of lice infestations.

Identifying Signs of Lice on Bedding

Detecting lice on bedding can be challenging due to the parasites’ small size and the complexity of bedding textures. However, there are a few telltale signs that can indicate their presence. Firstly, while adult lice may be difficult to spot due to their quick movement and small size, nits can be more easily identified. Look for tiny, white or yellow specks that resemble dandruff, yet unlike dandruff, these specks are difficult to remove because they are firmly attached to fibers.

Another sign is the presence of small, rust-colored stains on your bedding. These stains can be the result of crushed lice or a reaction to lice bites. Additionally, if you experience itching or notice red bites on your body upon waking, this could be a response to bite exposure during the night, suggesting that lice or nits are present in your bedding.

Rust-colored Stains on Your Bedding

Regular inspection of your bedding, especially if you or someone in your household is currently dealing with a lice infestation, is essential. Pay close attention to the seams, edges, and corners of your mattress, pillowcases, and bed linens, as these are areas where lice and nits are likely to hide and lay eggs. Identifying and addressing signs of lice on bedding swiftly can prevent the spread and aid in controlling an infestation effectively.

Preparing for Cleaning

After identifying a lice infestation in your bedding, preparation is key to effectively eliminate the parasites and prevent their return. The first step involves gathering all bedding, including sheets, pillowcases, blankets, and comforters, and sealing them in plastic bags to contain the infestation. Before laundering, vacuum all areas around the bed thoroughly, including the mattress, bed frame, and even the floor, to remove any lice or nits that might have fallen off.

It’s crucial to use the hottest settings permissible for your fabrics when washing and drying the items, as high temperatures are lethal to lice and nits. For items that cannot be laundered, such as pillows or stuffed toys, placing them in sealed plastic bags for a minimum of two weeks can help ensure any remaining lice and nits are no longer viable.

Key to a Successful Cleaning Process

Remember, the key to a successful cleaning process lies in meticulousness and attention to detail to ensure all traces of lice are eradicated from your bedding and bedroom environment.

Gathering Necessary Supplies

Before commencing the cleaning process to eradicate lice from your bedding and surrounding areas, it’s important to ensure you have all the necessary supplies on hand. Here’s a list of items that will aid in thoroughly cleaning and treating the infested zones:

  • Vacuum Cleaner: Essential for removing lice and nits from mattresses, bed frames, carpets, and any upholstered furniture.
  • Plastic Bags: Large enough to seal bedding, clothing, and other fabric items that may be affected. These bags will contain the infestation until items can be washed or stored long enough for lice and nits to die.
  • Laundry Detergent: A good quality detergent for washing all fabric items. Consider a detergent that contains enzymes, as it can be more effective in breaking down biological matter.
  • High Temperature Laundry Settings: While not a supply, it’s crucial to have access to a washing machine and dryer that offer high-temperature cycles to ensure the elimination of lice and nits.
  • Garbage Bags: For the disposal of vacuum cleaner contents and any items that cannot be saved or properly cleaned.
  • Lice Killing Spray: Optional, for use on items that cannot be washed but might benefit from chemical treatment. However, use with caution and prefer non-toxic options if available.
Disposal of Vacuum Cleaner Contents

Having these supplies ready before you start the cleaning regimen will streamline the process, making it more efficient and less stressful. Proper preparation ensures that once you begin cleaning, you can continue without interruption, significantly increasing your chances of completely removing the lice infestation from your home.

Safety Precautions

When undertaking the task of eradicating lice from your bedding and home, it’s imperative to follow certain safety precautions. Firstly, when using vacuum cleaners and washing machines, ensure they are in good working condition to avoid any potential hazards. If opting to use lice-killing sprays or chemical treatments, always read and follow the manufacturer’s instructions carefully.

It’s crucial to use these substances in well-ventilated areas to prevent inhalation of fumes, which can be harmful. Wearing gloves during the cleaning process can protect your skin from both the chemicals and any potential irritation caused by handling contaminated materials.

Additionally, when handling heavily infested bedding or clothing, minimize agitating the items before they are securely bagged to reduce the spread of lice and nits into the air. For items that cannot withstand high-temperature washing and drying, consider non-chemical alternatives such as freezing, but always ensure these methods are safe for the specific materials.

Remember, safety extends beyond the immediate cleaning process. Keep all plastic bags used to contain infested items out of reach of children and pets to prevent suffocation hazards. Lastly, proper disposal of vacuum bags or contents, and any non-salvageable items, is critical to prevent re-infestation and ensure the health and safety of everyone in the home.

10 Methods How to Clean Bedding after Lice

Method 1: Hot Water Washing

Set Your Washing Machine to the Hottest

One of the most effective ways to kill lice and their eggs is by washing bedding in hot water. Set your washing machine to the hottest temperature recommended for the fabric and add a suitable detergent. Wash all bedding items, including sheets, pillowcases, blankets, and comforters, in hot water to ensure thorough cleaning.

Method 2: High Heat Drying

After washing, it’s essential to dry bedding items at a high heat setting to kill any remaining lice or eggs. Use a dryer on the hottest setting recommended for the fabric and dry bedding thoroughly until completely dry. Avoid air-drying, as lice and eggs are more likely to survive in damp environments.

Method 3: Vacuuming

In addition to washing and drying, vacuuming can help remove any lice or eggs that may be lingering on bedding surfaces. Use a vacuum with a hose attachment to thoroughly vacuum mattresses, pillows, and upholstered furniture. Pay close attention to seams, crevices, and edges where lice and eggs may hide.

Method 4: Freezing

Another effective method for killing lice and eggs on bedding items that cannot be washed or dried at high temperatures is freezing. Place items such as stuffed animals, pillows, or delicate fabrics in a sealed plastic bag and place them in the freezer for at least 24 hours. The cold temperature will kill lice and eggs without damaging the fabric.

Method 5: Steam Cleaning

Steam Cleaning is an Excellent Way

Steam cleaning is an excellent way to sanitize bedding items and kill lice and eggs without the use of chemicals. Use a steam cleaner with a high-temperature setting to steam clean mattresses, pillows, and upholstery. Ensure thorough coverage and allow the items to dry completely before use. Repeat the process every few days until lice and eggs are completely gone.

There are also specific steam cleaners designed specifically for sanitizing and removing lice from hair. These devices, often called “lice combs,” emit hot steam that effectively kills lice and their eggs on contact. It is important to use caution when using these devices, as they can get very hot.

Method 6: Mattress Encasements

To protect your mattress from lice and prevent re-infestation, consider investing in a mattress encasement. These zippered covers encase the entire mattress, providing a barrier against lice and other pests. Choose a mattress encasement that is specifically designed to block allergens and bed bugs for maximum protection.

Method 7: Spot Treatment

If you suspect that lice may be present on your mattress or upholstery, spot treatment can help eliminate them quickly. Use a lice treatment spray or a mixture of water and essential oils to spot-treat affected areas. Allow the treatment to sit for the recommended time before wiping or vacuuming away any residue.

Method 8: Washing Bedding Separately

To prevent cross-contamination and ensure thorough cleaning, wash bedding items separately from other laundry. This will help prevent lice from spreading to other clothing or linens and ensure that all bedding receives proper treatment.

Method 9: Sunlight Exposure

Exposing bedding items to direct sunlight can help kill lice and eggs naturally. Hang washed bedding outside on a sunny day to allow the UV rays to penetrate and disinfect the fabric. Sunlight exposure can also help remove any lingering odors and freshen up bedding items.

Method 10: Repeat Treatment and Prevention

After cleaning bedding thoroughly, it’s essential to repeat the treatment process regularly to prevent re-infestation. Continue to wash bedding in hot water, vacuum regularly, and inspect for any signs of lice. Implement preventive measures such as routine checks, educating family members, and maintaining good hygiene habits to reduce the risk of future infestations.


In conclusion, dealing with lice infestation can be a daunting task, but thorough cleaning of bedding is paramount for eradication and prevention. By following the steps outlined in this guide, you can effectively remove lice and their eggs from your sheets, pillowcases, and blankets, ensuring a clean and hygienic sleeping environment.

Remember to wash bedding in hot water, use a hot dryer cycle, and consider using specialized treatments if necessary. Additionally, practicing good hygiene habits and regular inspection of bedding can help prevent future infestations.
