How To Determine What Are Mite Bites or Hive Welts
Scabies and hives both cause intense itching, but they have very different causes and treatments. Scabies is a contagious mite infestation; hives are an immune reaction that cannot be passed on.
Side-by-Side Comparison
| Feature | Hives | Comparison |
|---|---|---|
| Cause | Immune reaction | Sarcoptes scabiei mite |
| Contagious | No | Yes, through prolonged skin contact |
| Itch pattern | Any time | Worst at night |
| Look | Raised welts that move | Tiny bumps, burrows, between fingers and wrists |
| Duration | Welts fade in 24 hours | Persists until treated |
Signs of Scabies
- Intense itching, especially at night
- Thin, wavy burrows in finger webs, wrists, waist or genitals
- Other household members itching
Itching can start 2 to 6 weeks after first exposure.
Treatment Differences
Scabies needs a prescription scabicide such as permethrin, treatment of close contacts and washing of bedding. Antihistamines only ease itching. Read about whether hives are contagious.
When to Call 911
Call 911 or go to the nearest emergency room right away if hives come with trouble breathing, wheezing, tightness in the throat, swelling of the tongue or lips, dizziness or fainting. These can be signs of anaphylaxis, a severe allergic reaction that needs immediate treatment.
When to See a Doctor
See a doctor if your symptoms last more than a few days, keep coming back, cover large areas, or interfere with sleep or daily life. Patients with scabies and hives can book an online or in-person consultation at Dr. Tiffany Young’s Hives Treatment Center in San Francisco.
