Even the most meticulously cleaned homes can have bedbugs. In fact, you’re just as likely to find them in immaculate homes as you are in homes that are not as well maintained. So just where do they come from? The answer may surprise you: Dorm rooms, hotel rooms, cruise ships, and used furniture. Bedbugs simply hitch a ride in luggage or on clothing, furniture, and a variety of other items. Mature adults are about the size of an apple seed and reproduce three or more times per year.
