How to treat a flea bite at home? - in detail
Flea bites cause localized redness, swelling, and itching. Prompt home care reduces discomfort and prevents infection.
Cleaning the area removes saliva and reduces bacterial load. Wash the bite with mild soap and lukewarm water for 20–30 seconds, then pat dry with a clean towel.
Applying a cold compress limits inflammation. Place a clean cloth soaked in cold water or an ice pack wrapped in fabric on the bite for 5–10 minutes, repeating every hour as needed.
Topical agents alleviate itching and protect the skin:
- Hydrocortisone cream 1 % – apply a thin layer three times daily for up to seven days.
- Calamine lotion – spread gently after each washing session.
- Antihistamine gel containing diphenhydramine – use according to package instructions.
Oral antihistamines help control widespread itching:
- Cetirizine 10 mg once daily.
- Diphenhydramine 25 mg every 6 hours, not exceeding 150 mg per day.
If the bite becomes painful, warm, or exudes pus, consider an over‑the‑counter antibiotic ointment such as bacitracin or mupirocin, applied twice daily for three to five days.
Avoid scratching to prevent secondary infection. Keep fingernails trimmed and consider wearing cotton gloves at night if unconscious scratching occurs.
Monitor for signs of infection: increasing redness beyond 2 cm, swelling, warmth, fever, or foul odor. Seek medical attention if any of these develop.
Prevent future bites by treating pets with veterinary‑approved flea control products, regularly washing bedding, and vacuuming carpets and upholstery. Regular environmental treatment with insect growth regulators further reduces flea populations.
