Human itch mite (Scabies)

Natural Habitat

Human skin, specifically within the stratum corneum (the upper layer of the epidermis)

Diet & Feeding

Human skin cells and extracellular fluid

Behavior Patterns

The female mite burrows into the skin to deposit eggs, creating characteristic small, thread-like zig-zag lines. They are most active at night, which is when itching typically worsens. Transmission usually occurs through prolonged skin-to-skin contact.

Risks & Benefits

Causes scabies, a highly contagious skin infestation characterized by intense itching and a pimple-like rash. If left untreated, scratching can lead to secondary bacterial infections like impetigo or cellulitis. There are no known benefits to humans or the ecosystem.
