A bedbug bit me: how to treat? - briefly
Clean the bite with mild soap, apply an over‑the‑counter antihistamine or hydrocortisone cream to relieve itching, and watch for signs of infection, seeking medical care if swelling or severe reaction develops. Wash all clothing and bedding in hot water and dry on high heat to eradicate any remaining insects.
A bedbug bit me: how to treat? - in detail
If a bed‑bug has pierced your skin, the first step is to cleanse the area. Wash with mild soap and lukewarm water, then pat dry with a clean towel. This removes saliva and reduces the risk of secondary infection.
Apply a cold compress for 10–15 minutes to lessen swelling and numb the itch. After the skin has dried, use one of the following topical agents:
- 1 % hydrocortisone cream – diminishes inflammation and pruritus.
- Calamine lotion – soothes irritation and creates a protective barrier.
- Antihistamine cream (e.g., diphenhydramine) – blocks histamine release that causes itching.
If the bite becomes intensely painful, swollen, or shows signs of infection (pus, increasing redness, warmth), seek medical attention. A physician may prescribe:
- Oral antihistamines (cetirizine, loratadine) for systemic itching.
- Short‑course oral corticosteroids for severe inflammatory response.
- Antibiotics if bacterial infection is confirmed.
For persistent itching, avoid scratching to prevent skin breaks. Keep nails trimmed and consider using a soothing barrier such as a thin layer of petroleum jelly.
After treatment, monitor the site for 24–48 hours. Most reactions resolve within a few days; lingering redness or a hard lump may indicate a delayed hypersensitivity reaction, which also warrants professional evaluation.
Prevent future bites by eliminating the insects: wash all bedding and clothing in hot water (≥ 60 °C), dry on high heat for at least 30 minutes, vacuum carpets and furniture thoroughly, and seal cracks where insects can hide. Professional pest control may be necessary for extensive infestations.
