Where do head lice and crabs (genital) come from???

Question

Do they originate in dirt? In grass?? Where???

Please don't tell me from childrens heads!!

Just for the record, I've never had them and I don't plan on getting them.

Answer 1

They are spread person to person. They live well on skin sediments in blankets, rugs, hats (hence the children's heads), and therefore if one has them in their home the whole home needs to be thoroughly cleaned. The eggs last for a long time, therefore watch areas closely.
Lice spread the original killer plague in England by living in rugs and drapes and then jumping on to people to bite and infect them.

Answer 2

Lice (Crabs) are small, insect-like parasites. Parasites are animals that live off other animals. Lice live on the human body, most commonly on the skin, hair, and genital area. The originate from hair dirts and uncleaned areas for many days. They feed on human blood and lay their eggs on body hair and in clothing. The word "lice" is plural for the word "louse."

The three common types of lice infestation are head lice, body lice, and pubic lice. Head lice can be transmitted by sharing hats, combs, or hairbrushes. Epidemics of head lice are very common among school-age children. An epidemic is the rapid spread of a disease across a wide geographical area. Head lice do not cause typhus or other serious diseases.

Lice do not cause dangerous infections. However, they may carry organisms that cause more serious diseases, such as trench fever and typhus. Lice tend to be a problem primarily in overcrowded areas or areas that have inadequate facilities for bathing and laundry. They are often a problem among the homeless or in military or refugee camps. All humans are equally at risk to attack by lice, but elderly people are more prone to develop complications from lice attacks.

Treatment for lice involves two steps. First, a chemical is used to kill the adult lice. Two common products used for this are lindane (trade name Kwell) and permethrin (trade name Nix). Both products are strong chemicals and care must be used in applying them to the hair or skin.

The second step in treatment is removing nits. If left in place, the nits may survive and mature to become young lice. The easiest way to remove nits is with a fine-tooth comb or tweezers. In most cases, a single treatment destroys all lice and nits. If necessary, a second treatment can be applied a week later.

Treatment also involves washing the patient's clothing and bedding in hot water. These objects should then be ironed with a hot iron. Clothing and bedding can also be treated with an insecticide, such as malathion powder.-

Lice are at their best when attached to a host... you for example. Although they can fall off of someone and therefore be anywhere. They normally will live, and breed, without ever leaving your body. Eggs are attached to the hair and will not normally fall off. Once hatched, they will feed from you, causing an itchy, irritating sensation.

A bottle of RID shampoo will work wonders killing the adult as well as the eggs. You will also need to launder your clothing and bedding or set off an insect fogger in the areas you reside in. Lice are easily transfered during sex because the motion makes them become active.
