Bed bugs are small, parasitic insects that feed on the blood of humans and animals. They are often found in beds, bedding, and other furniture, and their bites can cause itching, swelling, and redness. While bed bug bites are not typically painful, they can be uncomfortable and can lead to secondary infections if they are scratched or broken open.
The severity of a bed bug bite can vary depending on the individual’s sensitivity to the insect’s saliva. Some people may experience only mild discomfort, while others may develop severe reactions, such as large, itchy welts or even anaphylaxis. Bed bug bites can also cause psychological distress, as they can be a sign of an infestation and can lead to feelings of anxiety and shame.
