Bedbugs commonly live close to human sleeping areas and are active at night; they hide in small spaces during the day. They feed on human blood by piercing a person’s skin and sucking blood. Some people are sensitive to bites which can cause skin welts, itching, swelling, and a burning sensation. Bed bugs have not shown to spread disease. While hiding during the day bedbugs can accidentally be moved into homes and lodging facilities with boxes, luggage, secondhand furniture, and clothing.
