When you have a skin parasite you'll usually know by experiencing itching and a skin rash.

Scabies infection appears as a red, bumpy, itchy rash on the skin.

It is caused by infection by the human itch mite, Sarcoptes scabiei.

The mites burrow deep into the skin leaving tell-tale red lines (burrows) that are visible with a magnifying glass.

The most common symptoms of scabies, itching and a skin rash, are caused by sensitization (a type of “allergic” reaction) to the proteins and feces of the parasite.

Severe itching (pruritus), especially at night, is the earliest and most common symptom of scabies.

A mite bite will look like small red bumps that are similar to pimples and they will most often be itchy as well.

Signs that you have mites or mite bites include.

Red, rash-like marks on your skin.
Small bumps that can become hard or inflamed.
Irritation, itching, and pain near the mark, rash, or bump.
Swollen or blistered skin near the bite.

The type of mites that live on human skin are sarcoptes scabiei, demodex folliculorum and the Demodex brevis.

Your doctor may be able to tell you have the mites by checking the rash or burrows on your body.

They might also try to remove one of the mites from its burrow.

They'll do this either by scraping your skin or pulling the parasite from its burrow with a thin needle.

When you lay in bed and get itchy you could be itchy as a result of bugs, itchy sheets, bed bugs, or because your skin dries out some when in bed which leads to itchy skin.

The skin naturally loses more water during the night as you're not staying hydrated while you sleep.

This can cause your skin to become dry and dehydrated, leading to itching.

When your skin crawls at night and nothing is actually crawling on your skin you are experiencing formication.

Formication is the sensation that bugs are crawling on or under your skin when they don't really exist.

Causes include mental health conditions such as depression, medical conditions like Parkinson's disease, certain prescription medications, or drug use.

When you feel something crawling in your hair but have no lice it could be that you have another insect called Demodex mites.

Demodex mites are microscopic eight-legged organisms found primarily in the sebaceous and hair follicle glands of your face.

Other causes of feeling something crawling in your hair without lice include delusional infestations, hallucination, substance abuse, a parasitic infestation, side effects from medication, or issues with the neurologic system.

Tiny black bugs on your skin are called body lice or body louse.

The body louse is a hematophagic ectoparasite louse that infests humans.

It is one of three lice which infest humans, the other two being the head louse, and the crab louse or pubic louse.

Despite the name, body lice do not directly live on the host.

Body lice will latch onto you and on your clothing if you've been to an unhygienic dwelling in the summer months.

Body lice will look like specks of tiny black bugs on your skin.

Not taking measures to get rid of them from your clothing and skin will cause severe bites from body lice.

The body louse is a hematophagic ectoparasite louse that infests humans.

It is one of three lice which infest humans, the other two being the head louse, and the crab louse or pubic louse.

Despite the name, body lice do not directly live on the host.

Body lice infestation is diagnosed by finding eggs and crawling lice in the seams of clothing.

Sometimes a body louse can be seen on the skin crawling or feeding.

Although body lice and nits can be large enough to be seen with the naked eye, sometimes a magnifying lens may be necessary to find lice or nits.

You can usually get rid of body lice by cleaning yourself and any personal belongings that may be contaminated.

Wash infested bedding, clothing and towels with hot, soapy water at least 130 F (54 C)  and machine dry them on high heat for at least 20 minutes.

Lice are parasitic insects that feed on human blood and can infest the head, body, and pubic area.

There are three types of lice that infest humans: body louse (Pediculus humanus corporis).
