Clean the affected skin with mild soap and water, then apply an over‑the‑counter antihistamine or hydrocortisone cream to alleviate itching and inflammation. If symptoms intensify or do not improve, consult a healthcare professional.
How can you treat bites from household bedbugs? - in detail
Bedbug bites typically appear as small, red, itchy papules, often clustered in a linear or zig‑zag pattern. The skin reaction results from the insect’s saliva, which may cause swelling, redness, and, in some individuals, a mild allergic response. Prompt symptom management reduces discomfort and prevents secondary infection.
Initial care focuses on cleaning the affected area with mild soap and water, then gently patting dry. Applying a cold compress for several minutes eases swelling and numbs the itch. After cleansing, a topical antiseptic, such as chlorhexidine or povidone‑iodine, can be used to reduce bacterial colonization.
Topical agents for itch relief and inflammation include:
- 1 % hydrocortisone cream, applied two to three times daily for up to one week.
- Calamine lotion, providing a cooling effect and barrier against scratching.
- 0.5 % pramoxine or 1 % diphenhydramine creams, delivering local anesthetic action.
If itching persists, oral antihistamines (e.g., cetirizine 10 mg or diphenhydramine 25 mg) may be taken according to package directions. Non‑steroidal anti‑inflammatory drugs (ibuprofen 200 mg) help control pain and swelling.
In cases of extensive lesions, secondary bacterial infection, or an exaggerated allergic reaction, a healthcare professional may prescribe:
- Short‑course oral corticosteroids (prednisone 20–40 mg daily for 5–7 days).
- Systemic antibiotics targeting Staphylococcus aureus or Streptococcus pyogenes, selected based on culture results.
Avoid scratching to prevent skin breakage. If a lesion becomes pustular, increasingly painful, or exhibits purulent discharge, seek medical evaluation promptly.
Long‑term management requires eliminating the source of infestation. Steps include:
- Washing all bedding, clothing, and curtains in hot water (≥ 60 °C) and drying on high heat for at least 30 minutes.
- Vacuuming mattresses, box springs, and surrounding furniture, then discarding the vacuum bag.
- Enclosing mattresses and box springs in zippered, bedbug‑proof covers and leaving them in place for a minimum of one year.
- Applying a certified residual insecticide to cracks, crevices, and baseboards, following label instructions.
- Consulting a licensed pest‑control operator for comprehensive eradication when the problem persists.
Effective symptom relief combined with thorough environmental control eliminates discomfort and reduces the likelihood of re‑exposure.
