How to treat a bedbug bite shown in a photo? - in detail
When a bite suspected to be from a bed‑bug appears, immediate care focuses on relieving symptoms and preventing infection.
First, cleanse the area with mild soap and lukewarm water. Pat dry with a clean towel; avoid rubbing, which can aggravate the skin.
Apply a cold compress for 5–10 minutes to reduce swelling and itching. If itching persists, a topical antihistamine cream (e.g., diphenhydramine 1 %) or a corticosteroid ointment (e.g., hydrocortisone 1 %) can be applied no more than three times daily.
Oral antihistamines such as cetirizine 10 mg or diphenhydramine 25 mg may be taken to control widespread pruritus, following the dosage instructions on the label.
For secondary bacterial infection signs—redness spreading beyond the bite, pus, or increasing pain—use an over‑the‑counter antibiotic ointment (e.g., bacitracin) and consult a healthcare professional promptly.
If the reaction includes severe swelling, difficulty breathing, or widespread hives, seek emergency medical attention; these may indicate an allergic response requiring epinephrine.
To minimize future incidents, inspect bedding for the characteristic small, rust‑colored spots and live insects. Wash all linens in hot water (≥ 60 °C) and dry on high heat for at least 30 minutes. Vacuum mattresses, furniture, and floor edges, then discard the vacuum bag or clean the canister. Encase the mattress and box spring in a zippered, bed‑bug‑proof cover and leave it on for several months to starve any hidden pests.
Regularly declutter sleeping areas, seal cracks in walls or baseboards, and consider professional pest‑management services if infestations persist.
Following these steps will alleviate discomfort, reduce the risk of complications, and help control the underlying problem.
