The lice cannot jump or fly, but can climb from one person to another. You can also catch the lice from clothes, bedding or towels used by someone with pubic lice, but this is rare.
Head lice may be spread by sharing towels or other items that have been in contact with an infested person's hair, although such spread is uncommon. Children should be taught not to share towels, hair brushes, and similar items either at poolside or in the changing room.
Pubic lice are small, crab‑like insects that are grey or brown‑red. They live in pubic hair, but can be on other body parts with hair (like the chest, armpit, face, eyelashes). Crabs can live for up to 24 hours on bedding, towels, and clothes.
Occasionally, pubic lice may be spread by close personal contact or contact with articles such as clothing, bed linens, or towels that have been used by an infested person. A common misconception is that pubic lice are spread easily by sitting on a toilet seat.
A common misunderstanding is that infestation can be spread by sitting on a toilet seat. This isn't likely, since lice cannot survive away from a warm human body. Also, lice do not have feet designed to walk or hold onto smooth surfaces such as toilet seats.
To kill any lice or nits remaining on clothing, towels, or bedding, machine-wash and machine-dry those items that the infested person used during the 2–3 days before treatment. Use hot water (at least 130°F) and the hot dryer cycle.
It can take up to 3 weeks after coming into contact with pubic lice before you notice any symptoms. They are spread through close body contact with someone who has them, most commonly sexual contact. The lice crawl from hair to hair but can't fly or jump.

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.
Lice and nits can live on pillows and sheets. Lice glue their eggs to the hair strands of their host. However, if a piece of hair with an egg falls out while the lice host is sleeping, an egg could end up on pillows or sheets.
For example, hats, scarves, pillow cases, bedding, clothing, and towels worn or used by the infested person in the 2-day period just before treatment is started can be machine washed and dried using the hot water and hot air cycles because lice and eggs are killed by exposure for 5 minutes to temperatures greater than ...
Adult pubic lice will die within 24 to 48 hours if they are away from a human body. Adult pubic lice are tan or gray in color and look like a crab (since the two front legs look like pincher claws). Pubic lice have three life stages and are a different size during each stage.
They hatch after 7-8 days. Over the next 13 to 17 days the larvae will change skin three times before reaching adulthood. Adult lice live for just under a month. Pubic lice can only survive and reproduce on people.
Head and body lice survive 7 to 10 days without a host. Whereas pubic lice (crabs) survive about 2 days off of their host. Any eggs that were laid will hatch after 5 to 10 days.

Never share towels, bedding, clothing, hats, and headgear. thoroughly. Insecticide sprays are not recommended because this will expose household members to unnecessary pesticides.
Females will lay approximately 30 eggs during their 3-4 week life span. Nits are oval and usually yellow to white. Pubic lice nits take about 6-10 days to hatch and become nymphs, which look like a smaller version of the adult louse. The nymphs undergo 3 molts before becoming adults.

Pubic lice move by crawling from hair to hair - they can't fly or jump. Body contact during sex is the most common way pubic lice are passed on. However, if a person has pubic lice it doesn't always mean it was passed on that way. Lice can also be passed on through close body contact like hugging and kissing.
You might notice really tiny dark brown specks in your underwear or your skin - this is lice poo (faeces).
