Head lice feeding on our scalp

The head lice feed by using their rough teeth to access scalp skin at the root of a hair or backside of the ears. Lice then insert their snout into a blood vessel, along with anticoagulants and feed much like a fly. So, that feeding style can be a starting place of irritation and will lead to the itching or scratching feature of the infestation. The lice can only manage to survive on human blood and require symbiotic bacteria to give back for nutritional defect in the blood food. Lice can have several blood dinners per day broken up by resting periods between feedings. Even though head lice are feeding on human blood, they don’tspread any microbiological disease agent.

.

Life cycle of public lice

Life cycle is running approximately 23 days from laying eggs to mature adults. They can live only a maximum of two days outside of the host due to the fact that they are parasites, feeding on hosts’ blood.

Life cycle of lice

They can be found not only public areas, but also the armpits, chest, in the beard or mustache, even rarely on the eyebrows and eyelashes.
There are three stages on complete life cycle of public lice. They are nit, nymph and adult.
Nits are the eggs of lice. They can be found firmly wrapped around the hair shaft of the affected area and hatched within at least 6 – 8 days. Nits like oval shape and normally yellow to white in color. They can alive for up to 14 days only, once removed from a host.
The baby louse is called as a nymph, while leading hatching. They mature about 7 days after hatching.  They must feed on human blood to continue their life. Nymphs molt three times before they become adults.p

Adult public lice cannot live even 2 days, without a host. Adult lice are tan to grayish white in color and ranges from 1-2 mm in size. Generally, the female louse larger than the male louse. She can lay up to 40 nits at a time or 30 – 90 nits in her life period.Adult crab lice live approximately 30 days while on the host.

Adult public lice on host

Adults and teenagers are most prone to these crab lice problems than children. But, if they can be found on children it could be a sign of child abuse or medication.

Their infections give redness, inflammation and itchiness in the genitals or public area. You can be visible lice or crowded lice; however, they never travel in great numbers. But, lack of those crawling lice could be a sign of a person is heavily affected by the nits or eggs before hatching. And also, it can be observed that they have a custom to attach themselves to one hair follicle and the speed in which they crawl is much slower than their mates, the body and head lice.

This can get worse during nighttime when lice becomes functioning and lay to rest their heads inside public hair follicles to feed on a person’s blood. At times, inflamed and discoloredness of the infested area can be a result of lice biting due to a reaction of protein in the saliva of the lice. As well as, small, red bumps or sores came from scratching. Continuous scratching and itching can make the area to become raw which leads to another bacterial infection. However, scratching can lead the public lice to spread. Your doctor may be identified that case at the beginning, he or she may treat the infection with an oral antibiotic.
