Are public lice, pubic lice and head lice the same thing?
Public lice is often a misspelling of pubic lice, but check the intended meaning. Pubic, head and body lice are distinct infestations with different care needs. A provider can identify live lice or eggs and exclude other causes of itching.
Can I use ordinary lice medicine on eyelashes or repeat it after any number of days?
Do not apply ordinary lice products near the eyes. Product, age, pregnancy and site affect treatment. Follow the specific label and professional advice about retreatment rather than a universal three-to-seven-day rule or repeated applications.
Do condoms or shaving guarantee that pubic lice will not spread?
No. Condoms do not cover all affected skin, and shaving is not a reliable treatment. Arrange evaluation of recent sexual contacts, treatment as advised and care for used clothing or bedding. Avoid sexual contact until the treatment plan is completed.
Sources for these answers
Pubic lice are parasitic insects, not bacteria or a virus. This article concerns pubic lice rather than head or body lice. They usually spread through close contact, and diagnosis and treatment should match the affected site, age and health situation.

Pediculosis means a lice infestation. Pubic lice commonly attach to pubic hair and can affect other coarse hair, including eyelashes. They crawl rather than jump or fly. Their presence is not proof of poor hygiene or the timing or source of an exposure.
Symptoms of Pediculosis disease
Itching, visible lice or attached eggs may occur, but other skin conditions can look similar. There is no fixed symptom day for everyone. Scratching can cause secondary infection. Eyelid involvement, significant skin infection or symptoms in a child need professional assessment.
There are 3 stages of lice found in the human body:
Eggs, nymphs and adults are life stages. Identification and treatment follow-up are more useful than trying to date a personal exposure from a general life-cycle chart. A provider can distinguish attached eggs and live lice from other material.
Incubation period of the disease
Itching may not begin immediately and does not establish when or from whom an infestation was acquired. Seek assessment when lice, eggs or persistent symptoms are noticed rather than waiting thirty days.
Causes of Pediculosis Disease
Pubic lice usually spread through close sexual contact and can sometimes spread through shared clothing or bedding. Toilet seats are not a usual route. Condoms do not cover all hair-bearing areas. A child with suspected pubic lice needs sensitive professional evaluation, not a public accusation or a diagnosis from a picture.
Treatment of Pediculosis disease
Use a product appropriate to the diagnosed infestation and follow its label and professional advice. Do not use ordinary pubic-lice treatments near the eyes, repeat them arbitrarily, or substitute pesticides intended for rooms or animals. Arrange contact care and follow-up if live lice remain.
Prevention of Pediculosis
Avoid sexual contact until the treatment plan for the affected person and relevant contacts is completed. Follow instructions for cleaning recently used clothing, towels and bedding. Do not use fumigants or rely on shaving. Discuss any indicated STI testing without assuming that lice diagnose another infection.
