What do bed bug bites look like and how are they treated? - briefly
Bed‑bug bites manifest as tiny, red, flat or raised welts, frequently arranged in rows or clusters and accompanied by itching or a mild burning sensation. Treatment includes gentle cleansing, topical corticosteroids or antihistamines to alleviate inflammation, and medical consultation for prescription options if reactions persist.
What do bed bug bites look like and how are they treated? - in detail
Bed‑bug bites appear as small, raised welts typically 2–5 mm in diameter. The central area is often pale or slightly red, surrounded by a darker, inflamed halo. Individual lesions may coalesce into linear or clustered patterns, especially when several insects feed in succession along a skin fold.
The eruptions differ from mosquito bites, which are usually isolated and more rounded, and from flea bites, which often present as multiple punctate marks with a distinct central puncture. Bed‑bug lesions commonly occur on exposed skin such as the face, neck, arms, and hands, but may also be found on concealed areas like the torso and thighs where the insects can access the host while resting.
The physiological response includes pruritus that intensifies within a few hours and may persist for several days. Secondary excoriation can lead to erythema, swelling, and, in rare cases, allergic dermatitis. Systemic symptoms such as fever or malaise are uncommon unless an extensive infestation triggers a hypersensitivity reaction.
Effective management comprises several steps:
- Clean the affected area with mild soap and water to reduce bacterial contamination.
- Apply a cold compress for 10–15 minutes to alleviate swelling and itching.
- Use over‑the‑counter topical corticosteroids (1 % hydrocortisone) or antihistamine creams to suppress local inflammation.
- Oral antihistamines (e.g., cetirizine 10 mg) may be taken to control persistent pruritus.
- For severe or persistent lesions, a short course of prescription‑strength corticosteroids can be considered under medical supervision.
- Eliminate the source by inspecting bedding, furniture, and cracks for live insects and their fecal spots; employ heat treatment (≥ 50 °C) or professional pest‑control methods to eradicate the infestation.
Prompt removal of the insects and thorough decontamination of the environment prevent further bites and reduce the risk of secondary infection.
