How should you treat a bedbug bite? - briefly
Clean the bite with mild soap and water, then apply a topical corticosteroid or antihistamine cream to alleviate itching and swelling; avoid scratching to prevent secondary infection. If redness expands, fever develops, or an allergic reaction appears, consult a healthcare professional promptly.
How should you treat a bedbug bite? - in detail
Bedbug bites appear as small, red welts, often in clusters. The skin reaction is primarily an inflammatory response to the insect’s saliva. Prompt care reduces itching, prevents secondary infection, and limits discomfort.
-
Clean the area – Wash with mild soap and lukewarm water for at least 30 seconds. Pat dry with a clean towel; avoid rubbing, which can aggravate the skin.
-
Apply an antiseptic – Use a cotton‑tipped applicator to spread a topical antiseptic such as povidone‑iodine or chlorhexidine. This step lowers bacterial colonisation risk.
-
Control itching –
• Over‑the‑counter antihistamine tablets (e.g., cetirizine 10 mg) taken once daily alleviate histamine‑driven pruritus.
• Topical antihistamine creams (diphenhydramine) or calamine lotion can be applied 2–3 times per day.
• For persistent swelling, a low‑potency corticosteroid cream (hydrocortisone 1 %) may be used for up to 7 days. -
Monitor for infection – Look for increasing redness, warmth, pus, or escalating pain. If any sign emerges, seek medical attention promptly; oral antibiotics may be required.
-
Avoid scratching – Scratching disrupts the epidermal barrier and introduces pathogens. Keep fingernails trimmed and consider wearing gloves at night if compulsive scratching occurs.
-
Manage systemic symptoms – If widespread rash, fever, or difficulty breathing develops, treat as an allergic reaction and obtain emergency care.
-
Prevent further bites –
• Wash all bedding, clothing, and curtains in hot water (≥ 60 °C) and dry on high heat.
• Vacuum mattresses, furniture, and floor surfaces; discard vacuum bags promptly.
• Encase mattress and box‑spring in a zippered encasement designed to trap insects.
• Reduce clutter where insects can hide.
Following these steps provides comprehensive care for a bedbug bite, alleviates symptoms, and reduces the likelihood of complications.
