This is a timely post as I just saw this in the office yesterday...
🐜 Chigger Bites (Trombiculosis)
🐜 What are Chigger Bites?
Chigger bites are caused by tiny mites (larvae of mites) that attach to the skin and feed on skin cells. They are very common in grassy, wooded, or outdoor areas, especially in warm climates like Florida.
What causes it:
Chiggers (larval mites) attach to the skin and inject digestive enzymes that break down skin cells, causing irritation.
Who it affects:
👶 Children who play outdoors
🏕️ Kids in grassy fields, parks, woods, or near lakes
🌴 Very common in the Southeast U.S.
Symptoms parents may notice:
🔴 Small red bumps or welts
🔥 Intense itching (often worse at night)
📍 Clusters of bites, often around:
• Ankles
• Waistline
• Behind knees
• Groin area
⏳ Itching usually starts several hours after exposure
How it spreads:
❌ Chigger bites are NOT contagious
🦠 They come from contact with grassy/brush areas — not from other people
What parents can do at home:
✔ Wash skin with soap and water after outdoor play
✔ Apply anti-itch creams (hydrocortisone)
✔ Use oral antihistamines if needed (per pediatric guidance)
✔ Keep nails short to prevent skin damage from scratching
✔ Cool compresses can help relieve itching
How long it lasts:
⏳ Itching can last several days to 1–2 weeks
⏳ Bumps may take up to 2 weeks to fully resolve
🚨 Red flag symptoms (seek medical care):
• Signs of infection (increasing redness, warmth, pus or blister formation)
• Severe swelling
• Fever
• Persistent worsening rash
