The first sign of lice is frequent scratching and itching of the head. They are often found at the nape of the neck or behind the ears.
Head Lice are small (sesame seed-sized) yellowish-white insects that live on the human scalp and feed off human blood from the scalp.
The female head louse can lay up to 10 eggs per day and over 100 eggs in her lifetime. Lice attach the eggs to the host’s hair shafts with a cement-like glue. These eggs can be seen by the naked eye in proper lighting. Eggs hatch approximately one to two weeks after they are laid.
注意: Head Lice are uncomfortable and can be embarrassing, but they do not carry infections or cause health problems.
While lice cannot jump or fly, they can move rapidly and are transferred by direct contact.
头虱可能潜伏在梳子等物品上, 刷, 帽子, 外套, 发带, 发夹, 耳机, 头盔, 填充动物玩具, 服装, 枕头, 还有剧院里的软垫座椅, 公共汽车, 或飞机.
提示: Encourage your family to avoid sharing personal care items and head wear. Head Lice and nits on bedding and clothing can be killed by washing, 浸泡, or drying items at a temperature greater than 130°F.
Removal of head lice typically involves a treatment process in which a product is applied to the infested person’s scalp to eliminate all live lice. Many treatments involve a secondary treatment to eliminate any lice hatching from eggs laid after the first treatment.
Removal of all nits after successful treatment with a pediculicide (lice killing product) is not necessary to prevent further spread. 然而, because lice killing products do not kill all the egg stages, Wyandot County Public Health recommends the manual removal of all nits, especially those that are attached within ¼ inch of the base of the hair shaft.
Complete removal of nits is common for aesthetic reasons and to reduce diagnostic confusion and the chance of unnecessary retreatment. Nit removal is often a lengthy process that can take more than one day.
注意: Treatments for head lice are generally safe and effective when used correctly. 有些治疗可能会引起瘙痒, or a mild burning sensation caused by inflammation of the skin on the scalp. Most products used to treat head lice are pesticides that can be absorbed through the skin. 因此, all medicines used for the treatment of lice should be used with care and only as directed.
Using shampoos and conditioners that list Sodium Lauryl Sulfate as an ingredient should act as a preventative and protect people from re-infestation. Be sure to follow treatment instructions about usage of shampoo and conditioner products before and after pediculicide treatments to ensure product effectiveness. Common product options including Sodium Lauryl Sulfate are Suave, 白色的雨, 草本精华, 和海伦皇后调理霜.
Head Lice can live for up to a week on furniture, clothing, and 填充动物玩具. Eggs can still hatch when not on the scalp but will soon die without the nutrients of human blood.
洗, 浸泡, or drying items at a temperature greater than 130°F can kill both head lice and nits. Routine vacuuming of floors and furniture is sufficient to remove lice or nits that may have fallen off the head of an infested person.
虽然很少需要, some experts recommend that items that may be contaminated by an infested person and that cannot be laundered or dry-cleaned should be sealed in plastic bag and stored for 2 weeks to kill any lice that already are present or that might hatch from any nits that may be present on the items.
头虱不会寄生在宠物身上. 宠物不会在头虱的传播中起作用.
注意: Use of insecticide sprays or fogs is NOT recommended. Fumigant spray and fogs can be toxic if inhaled or absorbed through the skin and they are not necessary to control head lice.
