There are many kinds of mite bites

In Insect Identification 254 views

The chiggers or mites of the harvest are probably the most common. They are larvae of ubiquitous mites, except in arid regions; They bite, feed on the skin and then detach. Outside the United States, these mites can be transmitters of Rickettsia tsutsugamushi (see Typhus of weeds). They do not dig into the skin, but because they are small they are not easily appreciated on the surface of the skin.

Mite species that bite and penetrate the skin include Sarcoptes scabiei, which produces scabies (see Scabiosis), and Demodex mites, which cause a scabies-like dermatitis.

Dermatitis is caused by mites that sometimes bite humans but are ordinarily ectoparasites of birds, rodents or pets and by mites associated with plant materials or stored food.

Bird mites can bite people who handle live chickens or birds as pets, or who have bird nests in their homes.

Mites of rodents, cats, dogs (especially puppies) and rabbits can sting people.

The mites of pigs (S. scabiei var suis), from farms or pets, can also bite humans.

The straw itch mite (Pyemotes tritici) is often associated with seeds, straw, hay and other plant materials; It is a soft-body parasite that is present in these materials. These mites often bite people who handle contaminated items. People who work in barns, who handle grass or hay seeds and who make dry plant arrangements are at higher risk.

The allergic dermatitis or itching of the shopkeeper is caused by several species of mites associated with stored grains, cheese and other foods. These mites do not sting, but cause allergic dermatitis because people are sensitized to their allergens or their waste products.

Dust mites in houses do not bite, but feed on flaked skin cells on pillows or mattresses and on the floor (especially carpets). They are important because many people develop pulmonary hypersensitivity to the allergens present in the exoskeleton and the feces of these mites.

Signs and symptoms
Most stings cause a version of pruritic dermatitis; the itching from the bites of the chiggers is especially intense.

Diagnosis
Clinical evaluation

The diagnosis of mite bites that do not penetrate the skin is presumptive and is based on patients’ history (eg, living, working and having fun in contaminated environments) and on physical examination. Mites are rarely found, because they fall off and fall after stinging, the skin reaction is generally late and most patients consult several days later. Injuries caused by different mites in general are indistinguishable and may superficially resemble other skin disorders (eg, bites from other insects, contact dermatitis, folliculitis).

The diagnosis of mites that penetrate the skin can often be presumptively achieved by the background and the presence of a scabies-like pattern in skin lesions. If the diagnosis is not clear or the treatment is ineffective, the diagnosis can be confirmed by skin biopsies.

Treatment
Topical corticosteroids or oral antihistamines

Antibiotic therapy for mites that penetrate the skin

For the treatment of scabies, see Scabies: Treatment.

The treatment of mite bites that do not penetrate the skin is symptomatic. Topical corticosteroids or oral antihistamines are used as needed to control itching until the hypersensitivity reaction resolves. Through the analysis of the possible sources, the doctor can help the patient avoid repeating the exposure to mites. For Demodex bites, a consultation with a veterinarian is required.

Key concepts
Dermatitis is caused by mites that sometimes bite humans but are ordinarily ectoparasites of birds, rodents or pets and by mites associated with plant materials or stored food.

Mites that itch and penetrate include Sarcoptes scabiei, which produces scabies or scabies, and Demodex mites, which cause scabies-like dermatitis.

Mites that itch usually cause pruritic dermatitis.

Diagnose patients by history and, for mites that penetrated, pattern of scabies-like skin lesions.

Treat symptoms and treat burrowing mite bites with antimicrobial therapy.
