Bed bugs hitchhike in luggage, cell phones, computers, clothing, diaper bags, furniture, shipping boxes, crates, etc. and on humans and animals. Bed bugs cannot fly but they are capable of moving surprisingly quickly across surfaces including ceilings, carpet, and beds, etc. During daylight hours, bed bugs hide and often commune in cracks and crevices including mattresses and bedding, bed frames, head boards and foot boards, baseboards, behind wall paper and electrical switch plates and outlets, furniture, and basically any place where they can wedge their paper thin bodies. Nocturnal and resilient, bed bugs can withstand temperatures between close to freezing up to 120 degrees Fahrenheit, they can complete development from egg to adult in as little as one month. Bed bugs are attracted to carbon dioxide, an indication of a warm-blooded body. Bed bugs emit an oily-sweet odor from thorax glands.
