What to apply to a domestic bedbug bite? - in detail
When a bedbug bite appears, the first step is to cleanse the area with mild soap and lukewarm water. This removes potential contaminants and reduces the risk of secondary infection.
Topical agents that alleviate itching and inflammation include:
- Over‑the‑counter hydrocortisone cream (1 %); apply a thin layer 2–3 times daily for up to a week.
- Calamine lotion; spread lightly to dry skin, reapply as needed.
- Antihistamine ointments containing diphenhydramine; use sparingly to avoid skin irritation.
- Aloe vera gel; soothing properties help calm redness and swelling.
Oral medications may be added if the reaction is extensive:
- Non‑prescription antihistamines such as cetirizine or loratadine; dosage follows package instructions.
- Ibuprofen or acetaminophen for pain relief; adhere to recommended limits.
Natural remedies with documented antipruritic effects:
- A paste of baking soda and water, left on the bite for 10 minutes before rinsing.
- A few drops of tea tree oil diluted in a carrier oil (e.g., coconut oil); apply twice daily.
- Cold compresses; hold a wrapped ice pack on the bite for 5–10 minutes to reduce swelling.
Preventive care after treatment:
- Keep fingernails trimmed to avoid skin damage from scratching.
- Wash clothing and bedding in hot water (≥ 60 °C) and dry on high heat to eliminate remaining insects and eggs.
- Inspect sleeping areas for signs of infestation; consider professional pest control if bites persist or new ones appear.
Seek medical attention if any of the following occur: intense swelling, spreading redness, signs of infection (pus, warmth, fever), or allergic reaction involving difficulty breathing or hives. In such cases, prescription‑strength steroids or antibiotics may be required.
