While head lice live in your hair and feed on your scalp, body lice usually live in your clothes and bedding. They travel to your skin several times a day to feed on blood. Your clothing seams are the most common places for body lice to lay their eggs (
To survive, adult head lice must feed on blood. An adult head louse can live about 30 days on a person's head but will die within one or two days if it falls off a person. Adult female head lice are usually larger than males and can lay about six eggs each day.
A person gets head lice because the insects crawl from person to person by direct contact or by sharing items — including combs, brushes and hats — with another person who has head lice. Poor hygiene doesn't cause head lice.
To live, adult lice need to feed on blood several times daily. Without blood meals, the louse will die within 1 to 2 days off the host.
Someone without lice has direct contact with the head of someone infested with lice. Head lice do not live on body hair, just head hair. You won't get lice simply being in the same room as someone with lice. You won't get lice shaking hands with an infested person.
The risk of getting infested by a louse that has fallen onto a carpet or furniture is very small. Head lice survive less than 1–2 days if they fall off a person and cannot feed; nits cannot hatch and usually die within a week if they are not kept at the same temperature as that found close to the scalp.
Catching Head Lice in Your Car
This may not sound like a long time, but it can be enough time to find a new host and start breeding. Just as they can fall off an infested person in the house when they're sitting on the couch or laying on a pillow, they can also fall off while they're in the car.
Washing, soaking, or drying items at a temperature greater than 130°F can kill both head lice and nits. Dry cleaning also kills head lice and nits. Only items that have been in contact with the head of the infested person in the 48 hours before treatment should be considered for cleaning.
Pillows? Just like with mattresses, lice can only live on any bedding—whether it's sheets, pillows, or comforters—for 1-2 days. Without a human scalp as a source for food (blood) for longer than 1-2 days, lice cannot survive.
Hairspray makes it harder for the louse to grab hold. The smell of hairspray and the use of solvents (sad but true) in them can also deter creepy crawlies from finding their way in. Not to mention that if you're tying longer hair back, you've got a double whammy.
Head lice most often affect children. The insects usually spread through direct transfer from the hair of one person to the hair of another. Having head lice isn't a sign of poor personal hygiene or an unclean living environment. Head lice don't carry bacterial or viral diseases.
Lice are attracted to the blood they get through your scalp – short, long, clean or dirty.
Common signs and symptoms of lice include: Intense itching on the scalp, body or in the genital area. A tickling feeling from movement of hair. The presence of lice on your scalp, body, clothing, or pubic or other body hair.
While head lice live in your hair and feed on your scalp, body lice usually live in your clothes and bedding. They travel to your skin several times a day to feed on blood. Your clothing seams are the most common places for body lice to lay their eggs (nits).
Lice are most often spread by head-to-head contact with another person who has lice, such as sleeping in the same bed. Although they do not survive long away from a human host, lice may also be spread by wearing another person's hat or clothing, or by using another person's comb, brush, or bedding.
Nits are the eggs of the female head louse. Once mature, she can lay up to eight nits a day, and live for 30 days. If you're wondering if nits can live on pillows and bedding, the answer is no. They need heat and blood to survive.
Nix out lice. From the #1 pediatrician-recommended lice removal brand*, Nix Lice & Bed Bug Killing Spray for Home will kill lice and bed bugs and is effective for up to 4 weeks. It's easy to use – simply spray on affected areas such as bedding and furniture.
Avoid sleeping in the same bed as the person with an active lice infestation. Avoid sitting where the person with lice has sat in the past two days. Wash linens and clothing in hot water and dry on high heat. Place stuffed animals, pillows and items that cannot be washed into an airtight bag for two weeks.
Head Lice Information for Schools. Students diagnosed with live head lice do not need to be sent home early from school; they can go home at the end of the day, be treated, and return to class after appropriate treatment has begun. Nits may persist after treatment, but successful treatment should kill crawling lice.
Heat Method:
Products such as Lousebuster are very effective but even a home hairdryer can successfully treat lice. DO NOT USE HAIRDRYER WITH MEDICATED TREATMENTS OR TREATMENTS THAT CONTAIN ALCOHOL--THESE PRODUCTS CAN CAUSE FIRE AND SEVERE BURNS TO YOUR CHILD!
It is not usually possible to get rid of lice in one day, as an infestation needs to be treated. However, there are treatments that can help get rid of lice and symptoms caused by lice more quickly. Lice infestations must first be treated by improving the hygiene of the infected person.
Machine wash and dry clothing, bed linens, and other items that the infested person wore or used during the 2 days before treatment using the hot water (130°F) laundry cycle and the high heat drying cycle. Clothing and items that are not washable can be dry–cleanedORsealed in a plastic bag and stored for 2 weeks.
Nits and nymphs: 1.5 to 2 weeks.
If you see nits and small, moving lice, you've likely had lice for 1.5 to 2 weeks. This is because you aren't seeing a lot of adult lice but are still seeing small, hatched nymphs along with lots more nits than a person who'd only been affected for a few days.
Clean all hair items by soaking in a lice treatment product for 10 minutes or cleaning with hot, soapy, or boiling water for 5 minutes. Never share towels, bedding, clothing, hats, and headgear. thoroughly. Insecticide sprays are not recommended because this will expose household members to unnecessary pesticides.
Wash items on a hot water cycle and dry on high heat for at least twenty minutes. The heated wash and dry will remove and kill any lice left. Carpets, mattresses, and flooring can simply be vacuumed and cleaned with everyday cleaning products.
