Can You Get Lice From Second Hand Clothes?

Yes, you can get lice from second hand clothes, but the risk is generally low. Lice cannot survive long without a human host, and most second hand items sit on shelves or in bags long enough for any lice to die off. However, if clothing was recently worn by someone with an active infestation, there is a real, if small, chance of transmission. Understanding exactly how lice spread through fabric helps you protect yourself without having to give up thrift shopping entirely.

The Three Types of Lice and How They Relate to Clothing:

Not all lice behave the same way when it comes to clothing. There are three main types: head lice, body lice, and pubic lice, and each has a different relationship with fabric and garments.

Head lice (Pediculus humanus capitis) are the most common and prefer to stay close to the scalp where warmth and blood supply keep them alive. They can fall onto clothing, but their claws are designed for gripping hair shafts, not fabric fibers.

This makes it harder for them to cling to a shirt or coat and crawl back onto a new host. That said, hats, scarves, hair ribbons, and hooded garments carry a higher risk than regular shirts because they contact the hair directly.

Body lice (Pediculus humanus corporis) are actually the type most closely linked to clothing. Unlike head lice, body lice live in the seams and folds of garments and only move to the skin to feed.

They can survive in clothing for up to one month, making second hand clothes a more realistic route of transmission for this particular type. People living in crowded or unsanitary conditions are at a higher risk, but anyone who wears unwashed second hand clothing without laundering it first could be exposed.

Pubic lice (Pthirus pubis), sometimes called crabs, are typically spread through close person-to-person contact but can also transfer via contaminated underwear, towels, or bedding. They survive on fabric surfaces for up to 24 hours, which is enough time to transfer if someone wears recently discarded clothing from an infested individual.

How Long Do Lice Actually Survive on Clothes?

This is the key question when assessing the real risk from second hand clothing. The survival time of lice off a human host varies by type, and understanding these windows tells you a lot about when the danger is real and when it is minimal.

Head lice typically survive for only 24 to 48 hours without a blood meal from a human scalp. Nits, which are lice eggs, require the heat and moisture of the scalp to hatch properly, and even if they are dislodged onto clothing, they will not hatch under normal conditions.

This means that a coat hanging in a thrift store for several days already carries a very low risk by the time you pick it up. Body lice are a different story. They are uniquely adapted to living in clothing and can survive in the seams and folds of garments for up to one month.

This is why unwashed second hand clothes, particularly items worn close to the body like underwear or thermal layers, carry a more meaningful risk when it comes to body lice specifically. If you are buying these types of garments second hand, washing them before wearing is absolutely essential.

Pubic lice fall somewhere in between, surviving up to 24 hours on fabric. The window is short, but not zero, and this is why laundering all second hand clothing before wearing it is the single most effective protective step you can take.

Which Second Hand Clothing Items Carry the Highest Risk?

Not all garments are equal when it comes to lice risk. Some items naturally come into closer contact with hair or skin, which makes them more likely to harbor lice if the previous owner had an infestation.

Hats, beanies, and scarves are the highest-risk items for head lice. These sit directly on or around the hairline, and a louse on someone’s scalp can easily fall or crawl onto these items. If you try on a hat at a thrift store or purchase one without washing it first, you are taking on more risk than you would with a regular garment.

Underwear and close-fitting base layers carry the highest risk for body lice and pubic lice. These garments sit directly against the skin for long periods and are exactly where lice prefer to live, feed, and lay eggs.

Many secondhand shopping experts advise against buying underwear at thrift stores for this reason, or at minimum insist on thorough washing before any use.

Coats, hoodies, and clothing with fur or fabric trim around the neck and hood also deserve attention. Hair can rub directly against these areas, and lice can be transferred to or from them more easily than with lower-body garments or items made from smooth, non-hair-contacting fabric.

Children’s clothing should also be washed before use since children are statistically the group most commonly affected by head lice, and their used clothing may carry a higher chance of exposure than adult items.

Do Thrift Stores Wash Their Clothes Before Selling?

This is something many shoppers assume but should not. Most major thrift stores, including well-known chains, do not wash donated clothing before putting it on the sales floor. Items are typically sorted, inspected for damage, priced, and displayed, but laundering is not a standard part of the process.

This means any lice present at the time of donation could still be present when you pick the item up, assuming enough time has not passed for them to die naturally.

The good news is that clothing usually spends a significant amount of time in the sorting and display process before it reaches you. For head lice, which die within 48 hours off a host, this gap is often long enough to reduce the risk significantly.

However, for body lice, which can survive in fabric for up to a month, this buffer is not always enough. The safest assumption when buying any second hand clothing is that it has not been washed, and you should treat it accordingly.

How to Safely Handle and Wear Second Hand Clothes?

The good news is that protecting yourself is straightforward and does not require you to give up the sustainability and savings of buying second hand. A few simple steps reduce the risk to near zero.

Wash everything in hot water before wearing it. Heat is the most reliable way to kill lice and their eggs. Washing in water above 130 degrees Fahrenheit (54.4 degrees Celsius) will eliminate any lice present on washable items. This single step removes the vast majority of any lice-related risk from second hand clothing.

Dry on a high heat setting. Running clothes through a hot dryer cycle adds a second layer of protection. The combination of hot washing and hot drying is recommended by health authorities as the most effective way to decontaminate fabric items that may have been exposed to lice.

For items that cannot be machine washed, seal them in a plastic bag for two weeks before wearing. Without a human host, any lice present will die within a few days, and two weeks provides a comfortable safety margin. This approach works well for delicate vintage pieces or items labeled dry clean only.

Avoid trying on hats, scarves, or hooded items in store without checking them carefully first. You can inspect the inner seams and fabric for signs of lice, such as tiny moving insects or small oval eggs attached to fibers. While this is rarely necessary, it is a sensible habit when shopping for high-contact items.

Recognizing a Lice Infestation Early

Even with all precautions, knowing the signs of a lice infestation helps you act quickly if you ever do pick one up. The most common symptom is persistent itching, particularly around the scalp, neck, and ears for head lice, and around the waist, armpits, and groin area for body lice. The itching is caused by a reaction to the saliva the louse deposits when it bites the skin.

You may also notice small red bumps or irritated skin at bite sites, and in some cases, you can see the lice themselves. Adult lice are around the size of a sesame seed, tan to grayish-white in color, and have six legs.

Nits appear as tiny oval shapes attached firmly to hair strands or fabric seams, and unlike dandruff they do not brush off easily. According to MedlinePlus, full-grown lice are typically found in clothing seams in someone with body lice, which is a useful diagnostic detail if you are trying to identify a body lice infestation.

If you suspect an infestation after wearing second hand clothing, see a pharmacist or doctor promptly. Over-the-counter treatments containing permethrin or pyrethrin are widely available and effective for most types of lice.

All clothing and bedding used during the infestation period should be washed in hot water and dried on high heat at the same time as treatment begins.

Common Myths About Getting Lice from Clothes

There is a lot of misinformation around lice and clothing that can cause unnecessary panic or, on the other end, false confidence. Clearing up a few of the most common myths helps you make sensible decisions rather than fearful or reckless ones.

Myth: Lice jump or fly from clothing to your head. This is false. Lice cannot jump or fly. They can only crawl, and they move relatively slowly. Transmission requires fairly direct contact between the infested item and your hair or skin. This is why a coat hanging on a rack away from your head poses very little threat even if a louse is present.

Myth: Only dirty or unhygienic people get lice from second hand clothes. This is also false. Getting head lice has nothing to do with personal cleanliness. Lice are equal-opportunity parasites that do not care how recently you showered. Anyone who wears unwashed second hand clothing from an infested donor is at risk, regardless of their hygiene habits.

Myth: You can always see lice on clothing before you buy it. Unfortunately, lice are small and can hide in seams, folds, and fabric textures. Nits are even harder to spot without magnification. You should never rely on a visual inspection alone as proof that a garment is lice-free.

So, Can You Get Lice from Second Hand Clothes?

The short answer is yes, but it is uncommon and entirely preventable. The risk is highest with body lice, which are uniquely suited to living in clothing, and lowest with head lice, which prefer the scalp and die quickly off a host.

The most important thing you can do is wash all second hand clothing in hot water and dry it on a high heat setting before wearing it, regardless of how clean the item looks or how reputable the store is. Second hand shopping is a genuinely sustainable and budget-friendly choice, and a small lice risk should not discourage you from it.

The Centers for Disease Control and Prevention notes that getting head lice is not related to personal cleanliness, and with the right laundering habits, the chance of picking up lice from a thrift store find is extremely small. A simple hot wash is all that stands between you and a completely safe second hand wardrobe.
