What does a typical bedbug bite look like? - briefly
A bedbug bite manifests as a tiny, red, raised spot that frequently appears in a linear or clustered pattern and can cause intense itching. The welts are typically 2‑5 mm across and emerge within a few hours after exposure.
What does a typical bedbug bite look like? - in detail
A bedbug bite is usually a small, raised wel‑wheal about 2–5 mm in diameter. The centre may be slightly lighter, surrounded by a reddish‑purple halo that fades to pink or pale skin tone as the reaction subsides. The lesion is often flat or only minimally raised, and the skin around it may appear swollen.
The bite typically appears after a delay of 12–48 hours following the insect’s feed. The latency period varies with individual sensitivity; some people notice a reaction within a few hours, while others experience no visible sign at all.
Common features include:
- Intense itching that can persist for several days.
- A cluster of three or more bites arranged in a linear or “break‑fast‑n‑coffee” pattern, reflecting the bug’s movement along a host.
- Absence of a puncture mark; the feeding tube is too fine to leave a visible scar.
- Possible secondary redness or irritation if the area is scratched.
In many cases, the reaction resolves without medical intervention, leaving only a faint, discoloured patch that may last up to two weeks. Persistent or severe inflammation, signs of infection, or widespread lesions warrant professional evaluation.
