What is a bed bug?Bed bugs are small wingless insects (they do not jump nor fly) that feed nocturnally upon the blood of warm-blooded animals. They are attracted by the heat and carbon dioxide emitted from your breath as you sleep. There are at least 92 known species of bed bugs found throughout the world; the most common species is the Cimex lectularius, (found in human environments).
What do bed bugs look like?What colour are bed bugs? Adult bedbugs are reddish brown (more red in the abdomen during and after a feeding), flattened, oval, and wingless, with microscopic hairs that give them a banded appearance.
How big are bed bugs? Adults reach 4 to 5 mm (an eighth to three-sixteenths of an inch) in length.
Bed bug eggs are super small, whitish, and difficult to see without magnification. When first laid, the eggs have a sticky covering which enables them to hold tight to wherever their mother is hiding out. Newly hatched bed bug nymphs are light yellow-brown, almost translucent, and become darker as they molt and reach maturity. Bed bug nymphs are no larger than a pinhead. See more pictures of bed bugs.
