Bed bugs are small, parasitic insects that feed on the blood of humans and animals. They are often found in mattresses, bedding, and other furniture, and they can bite people while they are sleeping. Bed bug bites can cause itching, redness, and swelling, and they can also lead to more serious health problems, such as allergic reactions and infections.
There is a common misconception that bed bugs only bite people on their faces. However, this is not true. Bed bugs can bite people anywhere on their body, but they are most likely to bite exposed areas of skin, such as the face, neck, arms, and legs.
