| 🔑 Key Takeaways |
| Chigger bites are intensely itchy, small red bumps caused by an immune reaction to the mite’s digestive enzymes. The severe itching typically lasts for several days and the visible bumps usually take 1 to 2 weeks to fully heal. Treatment focuses on immediate removal of any lingering mites with a prompt shower and subsequent aggressive control of the itching using oral Antihistamines and topical Hydrocortisone cream to prevent scratching and subsequent bacterial infection. |
Treatment Protocol (Symptom Management is Key)
Chiggers (larval mites) fall off the host long before the intense itching begins. Therefore, treatment focuses entirely on calming the body’s prolonged immune response and preventing secondary infection.
Immediate Action (The First Hour)
Shower Immediately: Take a bath or shower using soap and water. Gently but thoroughly scrub the skin to wash off any unattached chiggers that may still be migrating or attached to the skin.
Wash Clothes: Remove and wash all clothing worn during exposure in hot water and dry on high heat to kill any mites clinging to the fabric.
Symptom Management (Itch Relief)
Anti-Inflammatory Cream: Apply 1% Hydrocortisone Cream (OTC topical steroid) to the individual bites 2–3 times a day. This is the most effective way to suppress the intense local inflammation.
Oral Relief: Take an Oral Antihistamine (e.g., Cetirizine or Diphenhydramine) for systemic relief, especially for intense itching that disrupts sleep.
Drying/Soothing: Apply Calamine Lotion or a Baking Soda Paste (3 parts baking soda to 1 part water) to soothe the burning and dry out the small bumps.
Do NOT Scratch: This is the most crucial step. Scratching breaks the skin, inviting bacterial infection (Cellulitis) which drastically delays healing and causes scarring.
2. Duration and Healing Timeline
The severity of the itching and the total healing time are highly variable depending on the individual’s sensitivity.
| Symptom | Typical Duration | Notes |
| Itching Intensity | Peaks at 24 to 48 hours after the bite. | The itch is intense and often the reason people seek medical care. |
| Visible Bumps (Papules) | Usually persist for 1 to 2 weeks. | The hard, small red bumps will slowly flatten and fade if they are not scratched open. |
| Severe Cases | Can last 3 weeks or longer. | If the skin breaks due to scratching, the resulting bacterial infection will prolong the healing process and may require prescription antibiotics. |
3. When to Seek Medical Care
While chiggers do not transmit disease in the U.S., complications from scratching are common and require medical intervention.
Infection: If the bites show signs of spreading redness, warmth, pus drainage, or if the patient develops a fever or swollen lymph nodes.
Extreme Discomfort: If the itching is so severe that it cannot be controlled with over-the-counter medication and significantly interferes with sleep and daily life.
