How long before bedbugs move out of walls and into beds?

Bedbugs can move out of walls and into beds relatively quickly, often within a few days to a week after they sense a host nearby. They are nocturnal and typically emerge to feed on blood at night, especially when conditions are favorable, such as in the presence of warmth and carbon dioxide from sleeping humans. If infestations are not addressed, they can spread throughout living spaces, making timely detection and treatment crucial to prevent them from becoming a larger problem.
