Bed bug
At first sight, bed bug bites look like flea or mosquito bites or an allergic reaction. The skin becomes red, swollen, and starts to itch. However, there is a way to recognize the bed bugs’ “work.” The bites are very close to each other and look like little roads on the skin. Bed bugs’ bites are more painful than mosquitoes’. The numerous roads can be noticed in the morning as bed bugs hunt at night.
