How Long Can Nits And Lice Survive Off Of A Head
A few days: Lice starve to death in 1-2 days off the human host. Nits however survive longer. A nit hatches 7-9 days after the egg is laid. As a result it is recommended to first treat the lice on the "host" then wash clothes, bedcovers and vacume furniture. Also wash brushes and combs. ...Read more
Not by the number...: ...But by their location on the hair shafts. A head louse will attach her eggs (which is what nits are) to hair shafts at the point where they come out of the skin. As the hair grows, the nits move up from the scalp surface. Hair grows about 1 inch per month, on average - so if the nits are a half-inch away from the scalp, lice have been present for about 2 weeks; an inch away, 4 weeks; and so on. ...Read more
Lice: It may take 2 to 3 weeks (or sometimes even longer) to become aware of lice or nits. Itching does not occur for all people. ...Read more
Head Lice: The life span of an adult louse on a host ranges up to 30 days. During this time, the female head louse can deposit about 90 eggs. After incubating for seven to 10 days, the nits hatch and, after another 10 days, mature into adult head lice and the cycle begins again. Off the host, adult head lice can live about two to four days at 74 degrees fahrenheit (f) and one to two days at 86 degrees. ...Read more
I was exposed to a child who had been treated for head lice last wednesday night. I did not hug her but I am concerned. I have been checked several times since then and show no signs. How long should I have people keep checking?
Less than a week.:
Now many head lice are resistant to our traditional therapies. Cheap method which works is to apply gold listerine to the scalp x 1 hour and cover with shower cap. Then apply househould vinegar and comb through the entire head using sections of 10-20 hairs to remove all nits or eggs. Leave the vinegar x 1 hour then wash. Repeat in 1 wk.
New study showed oral Ivermectin works well. Need an rx! ...Read more
One treatment: Generally, one treatment (shampoo, nit comb, hair accessory/brush cleaning and linen/bedding change) should be sufficient to rid one of lice. However, reoccurrence is common due to re-infection from improper cleaning of accessories, brushes or linens. ...Read more

Lice: Tx of lice requires accurate identification of nits & / or lice. A pediculicide is usually used- otc like nix (permethrin) or rid or prescription meds like lindane or malathion. Work carefully through hair & remove individual nits. Purchase a special lice nit comb to aid you. Check for nits & remove as seen over the next 7 to 10 days. If there are nits after 7 to 10 days – a 2nd pediculicide tx may be needed. ...Read more
Define natural????: Some have offered experience that a stout vinegar, like pickling vinegar can be used as a wash over several days to a week and do this. The acidic solution does loosen the nits/egg casings so they can be removed easily with a nit comb. If this did not work one of the OTC or prescription products could be used. ...Read more
No Nit standard: The national pediculosis association (npa) recommends “no-nit” standards. This means that a child would meet reentry standards for schools, daycare, etc when they no longer have lice, nits or egg cases on their head/ in hair. Just to let you know – this is controversial. ...Read more
I have these long tan bugs with brown spots on then I have washed my hair with head lice shampoo and are still there what can I do?
Check every day: The usual plan is to have somebody remove every nit (egg) he can find after the first Nix (permethrin) shampoo. Checking one's hair and head for lice or nits, every day, will prevent lice from gaining a foothold again. Repeating the Nix (permethrin) shampoo in 1 week helps. As long as any and all nits (lice eggs) are quickly removed each day, the lice problem goes away. After 1 month of checking, one can just check weekly. ...Read more
Nix (permethrin) is not...: ...My favorite treatment, as many strains of head lice are now resistant to it. Elimite cream (applied to dry hair & left on overnight under shower cap) works better, although not officially approved for that indication. Malathion (ovide lotion) works fastest, but stinks, and is flammable! Kwell shampoo also works fast (repeat in 1 week), but like nix, (permethrin) resistance is common. ...Read more
Until clear: It is tedious but every last nit must be combed out to ensure cure (hours of combing). ...Read more
Lots of effort: There is a large movement to not coat the head with Permethrin or lindane due to potential neurotoxicity, and the risk is relevant. Non medicated products like licemd or ovid are effective, but nothing works better than the nit-loosening gel (ok, so it's not totally natural), the fine toothed comb, and lots of time and effort getting out all nits and lice. Then repeating the effort. ...Read more

Call your doctor: There are medications that can be used to kill the lice. Use them as directed (very important!). Wash all the bed linens in hot water and remove any stuffed animals, pillows that your child sleeps with until they are cleaned. Comb all the nits until they are no longer appearing- this is very time-consuming, but necessary. ...Read more
Itching, or none: Many children have no symptoms whatsoever, despite a good-sized infestation. Other children may have itching or a rash around the scalp. The diagnosis is made by finding live lice and/or nits in the hair. To check for lice, use a very fine-toothed comb to comb through wet hair section by section, looking for nits and adult lice. ...Read more
New activity: You can be infested with juvenile lice before they start laying eggs & not recognize the activity. If you have removed the egg casings & killed the lice, you must wait out the next 2 weeks to see if you have got them all. Any that were missed or hatching new would take up to 10 days to mature & lay recognizable eggs. ...Read more
