What does a bed‑bug bite look? - briefly
A bed‑bug bite appears as a small, red, raised spot that may develop a central puncture point and usually itches intensely. Bites often occur in groups of three or more, forming a linear or clustered pattern on exposed skin.
What does a bed‑bug bite look? - in detail
A bed‑bug bite typically presents as a small, raised welts measuring 2–5 mm in diameter. The initial lesion is often pale or pink, turning reddish after a few hours. The centre may remain lighter than the surrounding halo, giving a target‑like appearance. Itching is common, though pain is rare.
The reaction evolves over 24–48 hours. The redness intensifies, the swelling may become more pronounced, and the lesion can develop a tiny blister or a crust if scratched. In most cases the mark fades within a week, leaving a faint hyperpigmented spot that may persist for several weeks.
Typical distribution follows exposed skin during sleep: face, neck, shoulders, arms, and hands. Bites often occur in clusters or linear rows, reflecting the insect’s movement across the skin. A single isolated puncture is less characteristic.
Variability depends on individual sensitivity. Some people exhibit minimal signs, while others develop pronounced swelling, blistering, or secondary infection from scratching. Allergic responses can produce larger, more inflamed lesions and, rarely, systemic symptoms such as fever or malaise.
Key distinguishing features compared with other arthropod bites:
- Pattern: multiple lesions in a line or group versus isolated mosquito bites.
- Timing: bites appear after a night’s exposure; lesions may be noticed upon waking.
- Location: concentrated on areas not typically covered by clothing during sleep.
If uncertain, consult a medical professional for proper identification and treatment.
