Itchy after a bedbug bite, what should you do? - in detail
When itching follows a bite from a common household pest, immediate measures aim to reduce inflammation, prevent infection and limit further exposure.
First‑line care includes cleaning the affected area with mild soap and lukewarm water. Pat the skin dry, then apply a cold compress for 10–15 minutes to diminish swelling and numb the sensation. Over‑the‑counter topical agents such as hydrocortisone 1 % cream or calamine lotion may be spread thinly, adhering to product directions. Oral antihistamines (e.g., cetirizine 10 mg or diphenhydramine 25 mg) can alleviate systemic itching, especially when multiple lesions are present.
If the rash persists beyond 48 hours, intensifies, or shows signs of infection—redness spreading, warmth, pus, or fever—medical evaluation is warranted. A healthcare professional may prescribe stronger corticosteroids, topical antibiotics, or systemic antibiotics based on clinical findings.
Concurrent steps to prevent re‑exposure are essential:
- Inspect bedding, mattress seams and furniture for live insects, fecal spots (dark specks) and shed skins.
- Launder all linens, clothing and removable fabrics in hot water (≥ 60 °C) and dry on high heat.
- Encase mattress and box‑spring in zippered covers designed to trap pests; leave in place for at least one year.
- Reduce clutter, vacuum floors and upholstered items thoroughly, discarding vacuum bags promptly.
- Consider professional pest‑management treatment if infestation evidence is extensive.
Hydration and adequate rest support skin healing. Avoid scratching, as this can break the skin barrier and introduce bacteria. If scratching occurs unintentionally, keep nails trimmed and consider wearing gloves at night.
Monitoring the lesions for changes in size, color or discharge guides further action. Documentation of bite locations and timing assists both medical providers and pest‑control specialists in identifying infestation patterns.
