If they are exposed to cold temperatures, they typically will go dormant to conserve energy. Even extreme cold will likely not kill bed bugs right away.

Do Bed Bugs Hibernate in the Winter?

Bed bugs do not hide away in a cave for months like bears do or even like Cicadas when they go into the ground but they can enter a state of semi-hibernation, called diapause.  Diapause is an interval of energy conservation and slowed metabolism that enables bed bugs to go dormant, surviving without feeding for months. This is how they are able to stay secluded in an area for so long, making people seem like they have left. Bed bugs may enter diapause at temperatures below 60℉ in an effort to endure suboptimal conditions until said conditions improve. Even in this state, extreme cold can kill bed bugs if temperatures dip low enough.

Winter calls for flannel sheets and cuddling up by the fire. Unfortunately, bed bugs like the warmth too. All of the extra blankets and thick sheets only give bed bugs more places to hide.
