Wanzen
In short
Wanzen are small, flat, nocturnal insects that feed on the blood of humans and animals while they sleep.
In plain words
These pests hide in cracks and crevices during the day. They crawl onto people at night to bite, which causes itchy red bumps on the skin. They are very difficult to get rid of once they enter a home.
A simple example
A person wakes up with several small, itchy red welts in a straight line on their arm. This pattern often suggests that bedbugs have been feeding on them during the night.
Why it matters
They are a major health nuisance because they can spread diseases and cause severe sleep loss. Controlling an infestation requires professional help and careful cleaning.
Easy to mix up
People often mistake them for fleas, but bedbugs do not jump and prefer to stay near beds.
