How should a flea or bedbug bite be treated? - in detail
Flea and bedbug bites cause localized redness, swelling, and itching. Prompt care reduces discomfort and prevents secondary infection.
First, cleanse the area with lukewarm water and mild soap. Rinse thoroughly and pat dry with a clean towel. Applying a cold compress for 10‑15 minutes eases swelling and numbs the skin.
Topical anti‑itch agents such as hydrocortisone 1 % cream or calamine lotion can be applied two to three times daily. For more intense pruritus, oral antihistamines (e.g., diphenhydramine 25‑50 mg) may be taken according to package directions.
If a bite becomes painful, shows pus, or the surrounding skin turns warm, apply an over‑the‑counter antiseptic ointment (e.g., bacitracin) and keep the site covered with a sterile bandage. Monitor for signs of infection—red streaks, fever, or increasing pain—and seek medical attention if they appear.
For individuals with known allergies or severe reactions, a short course of oral corticosteroids (prescribed by a clinician) may be required. Epinephrine auto‑injectors are reserved for anaphylactic symptoms such as throat swelling or difficulty breathing.
Avoid scratching; repeated trauma can exacerbate inflammation and introduce bacteria. Keep fingernails trimmed and consider wearing gloves when applying creams.
Preventive measures include regular laundering of bedding at ≥60 °C, vacuuming carpets and upholstered furniture, and using approved insecticides or encasements for mattresses and box springs. Early eradication of the infestation minimizes new bites and the need for repeated treatment.
