Finding out someone in your household has head lice can send shivers down your spine. The immediate thought is often, “How do I get rid of them?!” followed quickly by, “Oh no, are they everywhere?” Your mind might jump to the bedding, especially the properly clean your pillows where infested heads rest every night. It’s a stressful situation, filled with itching (sometimes phantom itching!), worry, and the daunting task of cleaning.
Take a deep breath. While discovering lice is unpleasant, it’s a common issue, especially among school-aged children, and it is manageable. It’s not a sign of poor hygiene, and with proper treatment and some targeted cleaning, you can eradicate the infestation and prevent it from returning. This article will focus specifically on how to handle your pillows and bedding, demystify the process, and hopefully ease some of your anxiety.
Understanding Head Lice and How They Spread
Before diving into cleaning protocols, let’s quickly understand our tiny adversaries. Head lice (Pediculus humanus capitis) are parasitic insects that live exclusively on the human scalp. They need human blood to survive and thrive in the warmth close to the scalp.
- Lifespan: An adult louse can live for about 30 days on a person’s head. Female lice lay several eggs (nits) per day, gluing them firmly to hair shafts, usually close to the scalp. These nits hatch in about 7-10 days, and the baby lice (nymphs) mature into adults in another 7-10 days.
- Transmission: The overwhelmingly primary way head lice spread is through direct head-to-head (hair-to-hair) contact. This is why outbreaks are common among young children who play closely together.
- Survival Off-Host: This is crucial for understanding bedding risks. An adult head louse cannot survive long once it falls off a human head. Without access to a blood meal and the specific temperature/humidity of the scalp, most lice will die within 24-48 hours (1-2 days). Some sources suggest playing it safe and considering up to 72 hours, but survival beyond 48 hours is unlikely. Nits attached to fallen hairs also need scalp warmth to hatch and will typically die within a week if they are off a host.
So, can lice live in your pillows? Temporarily, yes, if one happens to fall off. But they won’t set up a permanent colony there. The risk of getting infested from a pillow, while not zero, is considered very low compared to direct head contact. However, for peace of mind and to eliminate even that small risk of re-infestation, cleaning bedding, especially pillows and pillowcases, is a standard recommendation after treating someone for lice.
How to Properly Clean Your Pillows After Lice
The main goal of cleaning pillows and bedding is to kill any live lice that may have fallen off the infested person’s head before treatment, or any nits attached to shed hairs. Heat is the most effective weapon.
Step 1: Strip the Bed
Remove all bedding immediately associated with the infested person, focusing on items used in the 48 hours before treatment began. This includes:
- Pillowcases
- Sheets (fitted and flat)
- Blankets/Duvet covers
- Any mattress protectors
Step 2: Wash and Dry Pillowcases and Linens
This is the most critical step for items that directly touch the head and hair.
- Wash: Place all washable items (pillowcases, sheets, washable blankets) in the washing machine. Use a hot water cycle – the water temperature needs to reach at least 130°F (54.4°C or roughly 60°C) to effectively kill lice and nits. Use your regular detergent.
- Dry: Transfer the washed items immediately to the dryer. Tumble dry on a high heat setting for at least 20-30 minutes. Again, the high heat is lethal to any remaining lice or viable nits.
Step 3: Dealing with the Pillows Themselves
Pillows require slightly different approaches depending on their type. Check the care label first!
- Machine-Washable Pillows: If your pillow’s care label indicates it’s machine washable (many synthetic fiber and some down/feather pillows are), wash it using the hot water setting (130°F / 54.4°C+) and detergent. Then, dry it thoroughly on high heat. Ensure the pillow is completely dry, as dampness can lead to mold or mildew; this might take more than one cycle or extra time.
- Non-Washable Pillows (Memory Foam, Specialty Fillings): Most memory foam or solid foam pillows cannot go in the washing machine. You have a few options:
- Option A: High Heat Drying Only: If the care label allows drying (even if not washing), place the pillow directly into the dryer on a high heat setting for at least 30 minutes. The heat will kill any potential lice or nits.
- Option B: Sealing/Isolation: If the pillow cannot withstand high heat, seal it tightly in a plastic bag (like a large garbage bag, sealed securely). Store it away for a period where lice cannot survive without a host. While lice die within 1-2 days, nits can take longer. Sealing for two weeks is the most conservative and widely recommended timeframe (CDC included) to ensure any potential nits would have hatched and the resulting nymphs died from lack of food. However, some sources suggest 48-72 hours is sufficient given the low survival rate off-host. Two weeks offers maximum peace of mind.
- Option C: Freezing (Less Common/Practical): Some suggest sealing the item in a plastic bag and placing it in a freezer (below freezing temperatures) for 12-24 hours. This is often less practical for bulky pillows.
Step 4: Vacuuming Around the Bed
While lice don’t infest carpets or furniture like bed bugs, vacuuming the mattress (especially seams and crevices), headboard, and the floor area around the bed is a good precautionary measure. This helps pick up any stray hairs that might have viable nits attached. Dispose of the vacuum bag or empty the canister immediately afterward.
What About Pillow Protectors?
Investing in zippered pillow protectors can be beneficial, especially if lice are a recurring concern (e.g., young children frequently bringing them home from school). Protectors provide a barrier that lice and nits cannot easily penetrate. In the event of an infestation, you would primarily need to wash the protector (following the hot wash/high heat dry method) rather than dealing with cleaning the entire pillow itself, saving time and effort. They also protect against dust mites and allergens, offering additional benefits.
Preventing Re-infestation: Beyond the Pillow
Cleaning pillows is just one part of tackling a lice infestation. To prevent the lice from coming back, you need a comprehensive approach:
- Treat the Infested Person(s): Follow the instructions for an approved lice treatment (over-the-counter or prescription) precisely. Many treatments require a second application 7-9 days later to kill any newly hatched lice. Comb through the hair with a fine-toothed nit comb daily or every few days for 2-3 weeks after treatment to remove any remaining nits or lice.
- Check Everyone: Inspect the heads of all household members and close contacts. Treat anyone found to have an active infestation (live lice or nits close to the scalp) at the same time. Treating people who share a bed with an infested person is often recommended even if no lice are found on them.
- Clean Other Items: Apply the same cleaning principles (hot wash/high heat dry or sealing for 2 weeks) to:
- Clothing, hats, scarves, coats worn by the infested person in the 48 hours before treatment.
- Towels used by the infested person.
- Hair accessories (combs, brushes, hair ties). Soak combs and brushes in hot water (130°F+) for 5-10 minutes. Alternatively, remove hair, seal them in a bag for 2 weeks, or wash with the hot laundry. Don’t share these items.
- Stuffed animals that have been in recent close contact, especially those slept with. Either wash/dry on high heat or seal in a bag for 2 weeks.
- Vacuum Furniture: Vacuum couches, chairs, and car seats where the infested person may have rested their head.
- Avoid Fumigants: Do NOT use insecticidal sprays or fogs in your home. They are unnecessary for head lice (which need a human host) and can be toxic if inhaled or absorbed.

People Also Ask (FAQs)
Q1: Can lice actually live in pillows? How long?
A: Head lice can end up on a pillow if they fall off someone’s head, but they cannot live or infest the pillow long-term. They need human blood to survive and will die within 1-2 days (48 hours) away from the scalp. Nits (eggs) on fallen hairs generally die within a week without scalp warmth. The risk of getting lice from a pillow is low.
Q2: Do I absolutely need to throw away pillows after a lice infestation?
A: No, you generally do not need to throw away pillows. Cleaning them effectively using high heat (washing/drying or drying alone) or sealing them in a plastic bag for two weeks is sufficient to kill any lice or nits. Replacing them is a personal choice, often for peace of mind, but not a necessity for lice control.
Q3: What temperature kills lice and nits on bedding?
A: A temperature of 130°F (54.4°C or approx. 60°C) or higher is needed to reliably kill both live lice and their eggs (nits). Ensure your hot water wash cycle and high heat dryer setting reach this temperature.
Q4: Is vacuuming enough to get rid of lice on pillows?
A: No. Vacuuming is good for removing fallen hairs with nits from surfaces like mattresses, furniture, and carpets, but it’s not the primary way to treat the pillow itself. Pillows require direct heat treatment (washing/drying) or sealing to ensure any live lice or viable nits within the filling or fabric are killed.
Q5: How often should I wash pillows after lice treatment?
A: You typically only need to clean the pillow (and other bedding/items) once after starting treatment, focusing on items used in the 48 hours prior. However, it’s a good practice to change and wash the pillowcase daily during the treatment and combing period (around 2-3 weeks) to catch any stray lice overnight and prevent re-infestation onto the treated head.

Conclusion: Breathe Easy, Clean Thoroughly
Dealing with head lice is undoubtedly stressful, but remember, it’s temporary. While the risk of lice spreading through pillows and bedding is low compared to head-to-head contact, taking the time to clean these items thoroughly provides crucial peace of mind and helps break the cycle of infestation. Focus on heat: wash pillowcases and linens in hot water and dry on high heat. Treat the pillows themselves with appropriate heat or by sealing them away. Combine this cleaning with effective head treatment and checking all family members. You’ve got this! By following these steps methodically, you can confidently say goodbye to lice and get back to resting easy on clean, lice-free pillows.
