What should you do if bedbugs bite? - briefly
Wash the affected skin with soap and water, then apply an over‑the‑counter antihistamine or hydrocortisone cream to reduce itching and inflammation; keep the area clean and seek medical attention if signs of infection appear. Inspect sleeping quarters for insects and arrange professional extermination to stop further bites.
What should you do if bedbugs bite? - in detail
If you discover that you have been bitten by bed bugs, begin by cleansing the affected area with mild soap and cool water. This removes potential irritants and reduces the risk of secondary infection. Pat the skin dry and apply a thin layer of an over‑the‑counter hydrocortisone cream or calamine lotion to alleviate itching and inflammation.
Take an oral antihistamine, such as diphenhydramine or cetirizine, if the reaction is pronounced. Follow the dosage instructions on the package and avoid exceeding the recommended amount. For severe swelling or persistent pain, seek medical evaluation; a physician may prescribe a stronger corticosteroid or a topical antibiotic if signs of infection appear.
Document the bite pattern—small, red, raised welts often in clusters—and keep a record of any changes over the next 24–48 hours. This information assists health professionals in diagnosing the cause and distinguishing bed bug reactions from other arthropod bites or skin conditions.
Simultaneously address the source of the infestation:
- Strip the bed and dressers of linens, pillowcases, and clothing; wash all items in hot water (≥ 60 °C) and tumble‑dry on high heat for at least 30 minutes.
- Encase the mattress and box spring in certified bed‑bug‑proof covers; keep them sealed for a minimum of one year.
- Vacuum carpets, floor seams, and upholstered furniture thoroughly; discard the vacuum bag or empty the canister into a sealed plastic bag and discard it outside the home.
- Inspect cracks, baseboards, and furniture joints; seal openings with caulk to limit hiding places.
- Apply a registered insecticide spray or dust to identified harborages, following label directions precisely.
- Consider professional pest‑control services for comprehensive treatment, especially in multi‑unit dwellings.
Monitor the situation for at least two weeks after intervention. If new bites appear, repeat laundering and vacuuming, and reassess treatment efficacy. Persistent exposure warrants a repeat professional inspection and possibly a more aggressive eradication protocol.
