Itch mite / Scabies mite

Natural Habitat

Human skin, specifically within the stratum corneum (outer layer) of the epidermis; can also survive briefly on clothing or bedding.

Diet & Feeding

Feeds on skin cells and extracellular fluid by burrowing into the skin.

Behavior Patterns

The female mite burrows into the skin to lay eggs; larvae hatch and migrate to the surface to mature and mate, after which the cycle repeats. These mites are highly contagious through prolonged skin-to-skin contact.

Risks & Benefits

Causes scabies, a skin infestation characterized by intense itching and skin rashes. While not life-threatening, it causes significant discomfort and can lead to secondary bacterial infections from scratching. There are no known benefits to humans or the ecosystem.
