What should you do if bedbug bites itch? - in detail
When the skin irritated by bedbug bites begins to itch, immediate relief and prevention of secondary infection are essential.
First, cleanse the affected area with mild soap and lukewarm water. Rinse thoroughly and pat dry with a clean towel. This removes any residual saliva that can exacerbate the reaction.
Apply a cold compress or a damp cloth for 10–15 minutes. The temperature reduction constricts blood vessels, reducing swelling and numbness, which diminishes the urge to scratch.
Topical treatments follow. Use over‑the‑counter hydrocortisone 1% cream or calamine lotion, spreading a thin layer over each bite. For more persistent itching, a topical antihistamine gel may be applied. Reapply according to package instructions, typically every 4–6 hours.
Oral antihistamines, such as diphenhydramine or cetirizine, can be taken if multiple bites cause widespread discomfort. Follow dosing guidelines on the label; avoid exceeding the recommended amount.
Do not scratch. Scratching breaks the skin, introduces bacteria, and can turn a mild reaction into cellulitis. If accidental scratching occurs, clean the wound again and apply a thin layer of antibiotic ointment.
Observe the bites for signs of infection: increasing redness, warmth, pus, or fever. If any of these appear, seek medical attention promptly.
While treating the symptoms, address the source to prevent recurrence. Remove all bedding, curtains, and clothing from the infested area. Wash fabrics in hot water (≥ 60 °C) and dry on high heat for at least 30 minutes. Vacuum carpets, mattresses, and furniture thoroughly; discard the vacuum bag immediately. Encase the mattress and box spring in a zippered, bedbug‑proof cover and leave it on for several months.
Consider professional pest‑control measures if the infestation persists. Heat treatments, steam, and approved insecticide sprays target hidden bugs and eggs.
Finally, maintain a clean environment: regular laundering, vacuuming, and inspection of travel luggage reduce future bites. These steps collectively alleviate itch, protect skin health, and limit further exposure.
