Wash the bite with soap and water and apply a cold compress to lessen inflammation. If itching persists, treat with an over‑the‑counter antihistamine or a low‑dose hydrocortisone cream.
What to do about a bedbug bite? - in detail
If a bedbug bite appears, immediate care focuses on reducing irritation, preventing infection, and confirming the source.
First, cleanse the area with mild soap and lukewarm water. Pat dry with a clean towel; avoid rubbing, which can worsen inflammation. Apply a cold compress for 10–15 minutes to lessen swelling and numb itching.
Second, treat the skin reaction. Over-the-counter hydrocortisone cream (1 %) or calamine lotion can be applied two to three times daily. Oral antihistamines such as diphenhydramine or cetirizine help control systemic itching, especially at night. If the bite becomes painful, a non‑steroidal anti‑inflammatory gel (e.g., ibuprofen gel) may provide additional relief.
Third, monitor for signs of secondary infection: increasing redness, warmth, pus, or fever. Should any of these develop, seek medical attention promptly; a clinician may prescribe topical antibiotics or oral therapy.
Fourth, reduce the risk of further bites.
- Wash all bedding, clothing, and curtains in hot water (≥ 60 °C) and dry on high heat for at least 30 minutes.
- Vacuum mattresses, box springs, and surrounding furniture; discard the vacuum bag or clean the canister afterward.
- Encase mattress and box spring in zippered protective covers rated for bedbug exclusion.
- Inspect seams, folds, and crevices of furniture; use a lint roller or sticky tape to capture hidden insects.
- Consider professional pest‑control treatment if the infestation persists or spreads beyond a single room.
Finally, document the bite pattern. Bedbug lesions often appear in linear or clustered arrangements (“breakfast‑lunch‑dinner” pattern) and are typically painless at first, later becoming itchy. Accurate description assists healthcare providers in differential diagnosis, distinguishing bites from other arthropods or allergic reactions.
By following these steps—cleaning, symptomatic treatment, infection surveillance, environmental control, and documentation—individuals can manage the immediate discomfort and limit the likelihood of additional exposure.
