As bed bugs grow they molt, shedding their skin five times before reaching maturity. A blood meal is needed between each successive molt. Adult females also must feed in order to lay eggs. Under favorable conditions (70-80°F), the bugs can mature fully in as little as a month, producing multiple generations per year. Cooler temperatures or limited access to blood prolong the development time.
Bed bugs are small, brownish, flattened insects that feed solely on the blood of animals. Although the common bed bug (Cimex lectularius) prefers feeding on humans, it will also bite other warm-blooded animals, including dogs, cats, birds and rodents. It has done so since ancient times; bed bugs are mentioned in medieval European texts and classical Greek writings back to the time of Aristotle.
The decline of bed bug populations in the 20th century is often credited to potent pesticides that had not previously been widely available. Other contributing factors that are less frequently mentioned in news reports are increased public awareness and slum clearance programs that combined pesticide use with steam disinfection, relocation of slum dwellers to new housing, and in some cases also follow-up inspections for several months after relocated tenants moved into their new housing.
Once you find where they nest. Steam everywhere, you might see them run so be prepared with sticky tape. After you steam and clean your bed, you need to proof it. Get the mattress and pillow covers. Get the wide masking tape and make it into a sticky tape on both sides. Tape around you mattress, around the legs of your bed frame. This will keep them from feeding on you.
Medicated shampoos–both over-the-counter and prescription–can help get rid of them, as can combing and re-combing your hair carefully and disposing of the critters. If you do get head lice, don’t share anything that goes on your head (including hats, brushes, headphones, or hair accessories), and make sure you clean bedding and clothing that could have been infested in hot water.
Blood spots found on one’s sheets, bites and the presence of bed bug feces and cast skins are some of the indications of a bed bug infestation. Bites are commonly found on the parts of the body that are more likely to be exposed to bed bugs during sleep – the hands, neck, face, shoulders, legs and arms. While not always the case, bed bug bites are often grouped together in a small area and at times may occur in a line or a zigzag pattern. Bites normally look like small, flat or raised areas that may become inflamed, itchy, red or blistered. Bed bug bite reactions don’t always appear immediately after you’re bitten and may take a few days to begin causing symptoms. However, not everyone reacts to bed bug bites in the same manner.
