Clean the affected skin with mild soap and water, then apply an over‑the‑counter antihistamine or hydrocortisone cream to reduce itching and inflammation. Simultaneously, wash bedding and clothing in hot water, vacuum the sleeping area, and consider professional pest control to prevent further bites.
What should I do when bitten by a bedbug? - in detail
If you notice a bite that appears after a night in a potentially infested environment, act promptly to reduce irritation and prevent secondary infection.
First, cleanse the area with mild soap and cool water. Pat dry with a clean towel; do not rub, as friction can worsen inflammation.
Apply a topical antiseptic such as hydrogen peroxide or a diluted povidone‑iodine solution. This lowers bacterial load and prepares the skin for further treatment.
To alleviate itching, use an over‑the‑counter antihistamine (e.g., diphenhydramine) or a corticosteroid cream containing 1 % hydrocortisone. Apply a thin layer no more than three times daily.
If swelling or redness expands beyond the bite site, or if you develop fever, seek medical evaluation. Prescription‑strength steroids or antibiotics may be required.
Simultaneously address the source of the infestation:
- Inspect bedding, mattress seams, and headboards for live insects, shed skins, or dark spotting.
- Wash all linens, clothing, and fabric items in hot water (≥ 60 °C) and dry on high heat for at least 30 minutes.
- Vacuum the sleeping area thoroughly, disposing of the vacuum bag or cleaning the canister immediately.
- Encase the mattress and box spring in zippered, bedbug‑proof covers; leave them on for several months to trap any hidden insects.
- Consider professional pest‑control treatment if visual confirmation of an active infestation is found.
Monitor the bite for changes over the next several days. Persistent pain, ulceration, or signs of an allergic reaction (hives, difficulty breathing) warrant urgent medical attention.
