Female bed bugs can lay 1-5 eggs per day in cracks or crevices. The reason they are called bed bugs is that they readily infest mattresses, bed frames and box springs. Eggs are laid along the edges of or around buttons on the mattresses. Eggs can also be glued to rough surfaces.
Bed bugs are small, flattened red creatures that are about 3/8” long. Their development time is approximately 21 days. During development they go through five nymphal instars. The bed bug does not have a larval stage, and develops by a process known as gradual or incomplete metamorphosis. Development of this kind results in an egg hatching to a form that closely resembles the adult, but in a much smaller form without fully developed reproductive structures. These newly hatched young are called nymphs that will go through several molts to reach adulthood.
Once fertilized, the female will lay eggs in cracks and crevices along the edges of mattresses, box springs and bed frames. Bed bugs will also inhabit other cracks and crevices throughout a room that is infested. These other areas include; behind picture frames, switch plate covers, loose wallpaper, baseboards or along the edges of carpets.
One of the major ways that bed bugs are spread is through human travel. Bed bugs in hotel rooms can pose a particular problem for frequent or even the occasional traveler. Imagine bed bugs entering your luggage as you sleep. One can then transport them to other hotels or back to their own home. Bed bugs peek period of activity is during the early morning hours, and the few hours before sunrise. It is during this time that bed bugs come out of hiding in search of a blood meal. Bed bugs feed almost exclusively on humans, and cause extremely itchy, irritating bites. The reason they are so itchy and irritating is that when the bed bug bites it injects enzymes and anticoagulants into the victim. These prevent the blood from clotting, and allow the bedbug to feed. The victim rarely feels the bite when it happens or during feeding, but several hours afterwards the itching starts.
