Bed bugs are small, brownish red, oval shaped pests that live on blood (like mosquitoes). They vary in size, between 1 mm (nymphs) to 4 mm (adults) and vary in width (1 mm to 2 or 3 mm). Bed bugs are not nocturnal by nature, the old saying “sleep tight, don’t let the bed bugs bite” is popular only because bed bugs are more frequently known to feed on us at night during sleep, when we are at our most vulnerable.
We have observed bed bugs, quite nonchalantly, out and about during the day time when the sun is out. I also noticed adult bed bugs were less afraid when visually caught by me, whereas bed bug nymphs (babies) were more quick to scurry and seek shelter when I caught them out and about. Although this might be unique to my situation, this may help you in locating them.

Bed bugs are very flat (when unfed) and this allows them to hide in virtually any location in your home – particularly true in older homes where deterioration and wear-and-tear are commonplace. Bed bugs are capable of hiding anywhere, in books, clothes, blankets, pillows, furniture, etc. However, they prefer to hide and seek shelter close by your bed, where they know you will be and where they are accustomed to feeding on you at night.
Bed bugs are attracted to CO2 (Carbon Dioxide), the bi-product of natural human breathing. Bed bugs are also attracted to warmth, because they are aware it is a sign that blood is available.
Bed bugs are “pure” pests, meaning they serve no purpose in the world – other than to live and feed on blood.
