Cheyletiella Mites On Humans causes: Symptoms & How To Treat It?

Mites are nuisance pests which inhabit on the external surface of animals and humans. Cheyletiella mites are one such species of mites which live on skin surface of animals such as dogs, cats and rabbits and human beings. In animals cheyletiella mites can cause extreme itching, scaling of skin and sometimes hair loss.

When this mite infests on human being it can produce severe itching, red rash and scaling of skin. The body parts most likely to get affected are arms, buttocks and torso. Unlike many other mites, cheyletiella does not penetrate in skin.

They live on keratin surface of upper layer of skin.

In most cases humans are infected when they come in direct contact with pets carrying cheyletiella. The parasites reproduce quickly and their life cycle is complete in 21 days. Therefore it is necessary to kill them with medications as quickly as possible.

Symptoms Of Cheyletiella Mite Infestation In Humans

Cheyletiella are eight legged pests having claw like mouth. The adult mite measures 0.3 millimeters in length. The characteristic feature of this mite is that it does not burrow deep in the skin. But it remains superficially on the upper layer of skin and thrives on keratin layer.

It cannot live more than 10 days after leaving the host.

Cheyletiella remain within the keratin layer and carry the scales with them. They are fast moving creatures. The scales appear similar to dandruff and therefore some people refer this symptom as walking dandruff. Besides scaling of skin, cheyletiella mites in humans are known to cause severe itching and red bumps on the skin surface. The common site of its affliction is arms, buttocks and torso.

Even though the affected site is severely inflamed, it is well demarcated from the surrounding healthy skin. Severe itching can lead to scratching and there is risk of secondary bacterial infection. Cheyletiella mite infection in humans needs constant animal contact. If the chain is broken by treating animal infected with the mite and vice versa, the symptoms alleviate within three weeks.

How To Treat Cheyletiella Mite Bite In Humans?

Normally infection of cheyletiella mites occurs due to contact with infected animal. Usually the pets like dogs, cats and rabbit get infected. It is necessary to treat the affected pets. The animal as well as the house including carpets and curtains should be disinfected.

Shampoo your pet with selenium sulphide shampoo. Use the shampoo once in a week for four weeks. Lather the pet with the shampoo and wait for half hour before washing. Pyrethrin shampoo is also used to clean your pet. Its effect is similar to that of selenium sulphide shampoo.

Consult the vet if you are finding difficulty even after shampooing for few weeks. Also ask him about the pet food. A healthy diet for pets is effective in dealing with such mites.

    I have dandruff looking things getting on everything in my house and on me. I believe it is this walking dandruff but, I had my vet scrape my dog and he said she doesn’t have it. I went to the dermatologist and she said that I have seborrheic dermatitis.

    I don’t believe it because something keeps getting on everything in my home. I have washed and vacuumed all beddings, furnishings etc. I can’t get rid of it and it is in my car too. It gets on everything that I touch and the items that I put into my car. Please, I need help with this.

    I have a very itchy rash on my legs and ankles. I have read that these mites can get inside a person’s nose. The skin inside my nose is very dry, and scaly. I have been controlling the itching with motrin and sometimes with benadryl. I think that I got this from my five month old puppy but because my vet has been treating her with worm and flea medication, she does not seem to be suffering as I am.

    I am going to mention this to my vet however. I guess I need to see a dermatologist. I am also washing all bedding and clothing in hot water because my cat and puppy play together. I guess I have to assume that the cat has this problem also. From what I have been reading, this does not seem to be serious, just very annoying and uncomfortable.

Also she thinks that these mites are in her pictures frames etc. really almost every where. Please help us to get rid of this problem.

      Yes it is very contagious but, if can clean up yourself with the shampoo before going home. After that be sure to wash your clothes immediately in hot water and borax.

    I found these on my cats and dogs. At first I thought it was scabies because of me. But as I read more I sounded more like something else. Because human scabies wont cause the kind of problems my dos and me were having. I never got burrows. These things love whereever there is water, mucus, sweat, drool, tears, cuts. Its crazy. I got a microscope and thought id seen a scabies mite. No looked again it was a walking dandruff mite. They can go in your pets nasal pasage. They can cause bad infestation in on your scalp and theirs. They can cause red bumps and bullous which is like a small part of skin ballooned up with our own liquid in it. I have one on my stomache. One is big, one is small. They also make baad bumps on my face w pus or without. They like going in my eyes. I am prescribed adderall and it worse when I take it. I break out more, im bit more, my animals get worse. Its been three years now. The vets werent able to find them on the dogs but thats ok I found the mite on microscope finally praise be to God! Now we are saving up money to get what we need to spray our place, use whats needed
    On us so we dont give it back to dogs, and give them stuff that will kill them on dogs. Ive tried frontline, oatmeal shampoo, 10 percent permethrin. They crawl up and look white on the very tip of their hairs. They are bigget than most mited tho. I am so ptsd over this. I never broke out before this. Vets find it hard to find so youll have to find it yourself. It will ruin your relationship. Its trying to w mine. My husband doesnt feel a thing. Mites dont like nicotine!!!! He gets the bites like me. I wish i could get rid of them. Showers are only worse because the more you bathe the worse youll feel them.

    I had gone to the vet on Tuesday and had to put two more cats down. It is worse than ever now. My home was treated with flea spray. I used permethrin 10 and nothing else. My head is shaved now because the longer the hair, the more itchy my scalp gets. I have skin tags on my eyes from rubbing them so much. I have used frontline on dogs, sulphur dip, oatmeal shampoo, dandruff shampoo. May god bless you all. If anything works I will post it.

    You need to take Ivermectin, often prescribed to people for “superlice”. I let my stupid dermatologist go ahead and think it was lice. I just wanted the pills that I knew would kill it. Dermatologists are the most pathetic idiots you will encounter in the world of medicine. Then, put your cat on revolution, a double dose if it is bad. I have read in the package that they did studies and administered 10 times the recommended amount to 6 week old kittens without any bad reactions- again, listed right in the dosing instructions. This will clear it up. My kids and I went through the hell for months. Vets and doctors don’t understand these nasty things are making a comeback.
