What to apply to a flea bite at home? - in detail
Flea bites usually appear as small, red punctures surrounded by a raised, itchy halo. The skin may become inflamed and develop a secondary rash if scratched.
First, clean the area with mild soap and lukewarm water. Pat dry with a clean towel; avoid rubbing, which can aggravate irritation.
Apply one or more of the following topical agents:
- Cold compress – 10‑15 minutes, several times a day, reduces swelling and itching.
- Hydrocortisone cream (1 %) – thin layer applied 2‑3 times daily; limits inflammatory response.
- Calamine lotion – soothing film; reapply after washing or sweating.
- Antihistamine gel or cream – contains diphenhydramine; eases pruritus for up to 4 hours.
- Aloe vera gel – natural anti‑inflammatory; cools skin and promotes healing.
- Tea tree oil diluted 1 % – antiseptic; apply with a cotton swab, monitor for irritation.
Oral measures may complement skin treatments:
- Cetirizine or loratadine 10 mg – taken once daily; controls systemic itching.
- Ibuprofen 200‑400 mg – every 6‑8 hours; alleviates pain and inflammation.
Avoid scratching; use short fingernails and consider wearing gloves if necessary. Keep the affected region uncovered to allow air circulation, unless a dressing is required to prevent infection.
Seek professional care if any of the following occurs:
- Rapid expansion of redness or warmth, indicating bacterial infection.
- Development of pus, blisters, or ulceration.
- Persistent itching beyond 48 hours despite treatment.
- Signs of an allergic reaction such as swelling of lips, tongue, or difficulty breathing.
Prompt, consistent application of the measures above typically resolves flea bite discomfort within a few days.
