Bed bug behavior
Bed bugs are built for one thing: staying hidden while staying fed. Understanding how they live and move may help you spot an infestation early:
Habitat
Bed bugs prefer to find hiding places as they hate being out in the open. They can be found anywhere where humans are motionless for a long period. This can include beds (including box springs, mattresses, headboards, and mattress covers); couches (including cushions and pillows); and reclining chairs.
As an infestation grows, bed bugs can spread to curtains, ceiling edges, electrical outlets, and behind pictures.
Feeding
A bed bug’s anatomy is designed to feed on blood. However, bed bugs do not have to feed every night. They can go for several days, even months, without a meal, but they do require a blood meal every time they shed their skins and enter a new life stage.
After a blood meal, a bed bug will become engorged, and its skin color will appear a darker reddish-brown.
