Sarcoptes scabiei — what scabies looks like and how to handle it
A tiny mite called Sarcoptes scabiei causes scabies. It burrows into the top layer of your skin and lays eggs. The result is intense itching, often worse at night, and small red bumps or thin tracks on the skin. Scabies is common, uncomfortable, and usually easy to treat if you catch it early.
How to recognize scabies
Typical signs are itching that wakes you up at night, small raised bumps, and short thread-like lines where the mite has burrowed. Common spots are between the fingers, on the wrists, inner elbows, waistline, buttocks, and around the nipples or genitals. Babies and young kids may get scabies on the head, face, palms, or soles. If you notice intense itching plus any of these patterns after close contact with someone who’s itchy, scabies is likely.
Doctors diagnose scabies by looking closely at the skin. They may see burrows with a dermatoscope or take a skin scraping to confirm the mite under a microscope. You don’t always need a scraping if the signs and history match — but it helps when the picture isn’t clear.
Treatment and simple prevention steps
First-line treatment is usually a topical cream called permethrin 5%. You apply it from the neck down (or head to toe for children and older adults) and leave it on for the time your doctor recommends, often overnight. For widespread or crusted scabies, or when topical treatment isn’t practical, doctors may prescribe oral ivermectin. Typical ivermectin dosing is weight-based and sometimes given as two doses one week apart, but follow your prescriber's instructions.
Treat all close contacts at the same time, even if they don’t have symptoms yet. Wash bedding, towels, and clothing used in the previous 2–3 days in hot water and dry on high heat. Items that can’t be washed can be sealed in a plastic bag for several days — mites won’t survive long off a human host. Vacuum cushions and furniture to remove loose mites or skin.
Over-the-counter creams and home remedies rarely kill the mites and can cause skin irritation. Stick with treatments your healthcare provider recommends. If symptoms persist after proper treatment, return to your clinician — sometimes re-treatment or checking for a secondary skin infection is needed.
See a doctor right away if you have severe widespread crusting, a weakened immune system, a baby or elderly person with symptoms, or signs of a bacterial skin infection (like increasing redness, warmth, swelling, or pus). Crusted scabies is more contagious and needs specialist care.
Scabies is annoying, but with the right treatment and a few cleanup steps, you can stop the itching and prevent spread. If you’re unsure, reach out to a healthcare provider — quick action usually means faster relief and fewer people affected.
