Bed bugs are oval brownish insects. They live off feeding on blood. Adults are normally the size of an apple seed, but do swell and become reddish in color after feeding. Bed bugs do not fly but can move quickly across floors, walls, ceilings, and furniture. Immature bed bugs (nymphs) shed their skin for each life cycle. They require a blood meal before each shedding. In favorable conditions nymphs can become adults in as little as one month. A female bed bug can lay hundreds of eggs in her lifetime making bed bugs very quick at increasing population. You can bring bed bugs into your home in many different ways. Luggage, cloths, used furniture, guests, and more. Bed bugs don't have colonies or hives but do tend to live in groups in hiding places. Most common hiding places are box spring, mattress, and bed frame. Bed bugs can spread to behind baseboards, picture frames, couches, dressers, nightstands, and any other crevices in home. Bed bugs live solely on blood so having them in your home is not evidence of a dirty home. Bed bugs are active mainly at night while you are sleeping. Their bites are painless at first but most of the time (not always) will leave a welt and itch. Bites can be anywhere on the body.
