What type of habitat do bed bugs prefer when not feeding?

Bed bugs prefer tiny cracks and crevices near their host when not feeding because these environments provide both safety and proximity to a food source. They are naturally nocturnal and seek out places where they can hide during the day, which makes small, concealed spaces ideal for their survival. The close proximity to their hosts allows them to easily access a meal when they need to feed, typically at night.

Options such as open fields and high trees do not offer the concealment or the immediate access to hosts that bed bugs require. Underwater plants are irrelevant as bed bugs are terrestrial insects and do not inhabit aquatic environments. The choice of tiny cracks and crevices showcases bed bugs' adaptation to living alongside humans, making them effective pests in households and other areas where people reside.
