insektsbett

Insektsbett, or insect bite, is a skin reaction caused by the mouthparts or saliva of blood-feeding insects. Unlike stings that inject venom, bites typically result from puncture wounds that may become itchy welts or reddened papules. Reactions vary widely; some people develop mild itching, others experience pronounced swelling, blistering, or an allergic response. In some cases, bites may become secondarily infected through scratching.

Common culprits include mosquitoes, which produce small, itchy red papules; bed bugs, which leave bite clusters often in lines; fleas, which commonly bite ankles or lower legs and produce grouped lesions; and ticks, which may bite silently and carry the risk of transmitting diseases such as Lyme disease or other tick-borne infections. Other biting insects include biting midges, sandflies, and gnats.

Diagnosis is usually clinical, based on history and the appearance of the lesions. Consider exposure history, travel, and pest infestations. If multiple bites occur in a linear pattern or if there is fever, swelling around joints, or signs of infection, seek medical advice. Tick bites may require prompt removal and monitoring for symptoms of tick-borne diseases.

Treatment is typically supportive. Most bites resolve within a few days to a week. Self-care includes washing the area, avoiding scratching, applying cold compresses, and using oral antihistamines or topical corticosteroids to reduce itching. Pain can be managed with standard analgesics. Seek medical care for signs of infection or a severe allergic reaction.

Prevention focuses on reducing exposure to biting insects. Use insect repellent containing DEET, picaridin, or IR3535; wear protective clothing; sleep under screened or netted areas; and address environmental factors that attract insects. For bed bugs, professional pest control may be necessary.
