What do bed bug bites look like on a person and how to treat them? - briefly
Bed bug bites manifest as tiny, red, itchy welts that may appear in a line or cluster on exposed skin. Treat them by washing the area, applying topical anti‑itch ointments or oral antihistamines, and consulting a healthcare professional if severe reactions develop.
What do bed bug bites look like on a person and how to treat them? - in detail
Bed‑bug bites typically appear as small, raised welts about 2–5 mm in diameter. The central area may be pale or slightly pink, surrounded by a reddened halo that can become darker as the reaction progresses. Bites often occur in clusters or linear patterns, reflecting the insect’s feeding habit of moving along the skin. Common locations include exposed skin such as the face, neck, arms, and hands, but bites may also be found on the torso and legs, especially where clothing is thin.
The reaction time varies; some individuals notice itching within minutes, while others experience delayed swelling that peaks after several hours. The itch is usually intense, and scratching can lead to secondary infection, evidenced by increased redness, warmth, or pus formation.
Treatment focuses on symptom relief and preventing infection:
- Gently wash the affected area with mild soap and lukewarm water to remove irritants.
- Apply a cold compress for 10–15 minutes to reduce swelling and discomfort.
- Use over‑the‑counter oral antihistamines (e.g., cetirizine 10 mg) to control itching.
- Apply topical corticosteroid creams (e.g., 1 % hydrocortisone) two to three times daily for up to one week.
- If signs of infection appear, seek medical attention for possible antibiotic therapy.
Long‑term management requires eliminating the insects:
- Launder all bedding, clothing, and curtains in water ≥ 60 °C, then dry on high heat.
- Vacuum mattresses, furniture, and floor surfaces; discard the vacuum bag immediately.
- Encase mattresses and box springs in zippered protective covers rated for bed‑bug resistance.
- Seal cracks and crevices in walls, baseboards, and furniture to reduce harborage sites.
- Engage a licensed pest‑control professional for chemical or heat treatment of infested rooms.
Monitoring after treatment is essential; new bites or live insects indicate incomplete eradication and necessitate repeat interventions.
