In Europe and Asia, Japan and South Korea have experienced successive outbreaks of bed bug crises, which are blood-sucking creatures commonly known as “bed bugs.” In the past five years, bed bugs have gradually become more common in China due to factors such as international tourism and foreign workers. Dermatologists revealed that bed bugs tend to bite people in the same area of skin, causing small, red, itchy bumps to appear in rows or groups on the face, neck, arms, etc. following a few hours or days. Exposed areas of skin such as the back and legs.
Dermatologist Chen Yucong said that bed bugs, also known as bed bugs (scientific name: Cimicidae), are small parasites that are mainly active at night. They suck human blood and leave red marks on the skin. Bed bugs are very small, regarding 1.5 to 5 millimeters, and are light brown or dark red in color. They have no wings, but can crawl. Their bodies are shaped like a flat oval, and they become swollen following sucking blood.

Doctors point out that when bed bugs bite a person, they inject a saliva that contains anesthesia, vasodilation and anti-coagulant functions to facilitate continuous blood sucking. Therefore, the bitten person may not feel pain or itching immediately, so bed bugs are easy to bite at the same time. Biting movements on an area of skin, causing small, red, itchy bumps to appear in rows or clusters hours or days later on exposed areas of skin such as the face, neck, arms, back, and legs .
Chen Yucong explained that being bitten by bed bugs can cause allergic reactions of varying degrees. Fortunately, most people only experience mild discomfort and itching. A few people may experience severe redness, swelling and inflammation, or even severe allergic reactions. “If you suspect that there is a bug in your home, If bed bugs are infested, you can use a flashlight or magnifying glass to check the gaps in bedding or furniture to see if there is bed bug excrement and peeling skin, such as black or brown dots, empty shells or dander, which are left behind by bed bugs. Check for traces of blood on the bedding, or look for blood spots on the bedding.”
