The itch mite, scientifically known as *Sarcoptes scabiei*, is a tiny parasite that burrows into the skin, causing intense itching and irritation. These mites are microscopic, measuring about 0.3 millimeters in size, and are often spread through close personal contact or sharing contaminated items like clothing and bedding. Infestations by itch mites lead to a condition called scabies, characterized by red rashes and sores. Treatment typically involves topical medications that kill the mites and relieve symptoms. Maintaining good hygiene and avoiding close contact with infested individuals can help prevent the spread of these pests.
