Bed bugs primarily live where their hosts (people or animals) live and spend a lot of time — in mattresses, bed frames, headboards, box springs, and bedding. They like to stay in small spaces in groups and hide in spots where they can easily feed.
Many times, bed bugs enter homes or places by traveling on luggage, clothing, boxes, used furniture, and couches, among others. They can also travel from apartment to apartment, home to home, and room to room.
These insects live all over the world, and date back to ancient times.
