How Long Do Bed Bugs Survive?

Without Feeding: Can live about 20-400 days, depending on conditions. 

Adults: Typically live for 4-6 months, but can survive over a year in favorable conditions. 

Temperature Influence: Thrive in temperatures between 70°F and 80°F; lifespan decreases in extreme temperatures. 

With Regular Feeding: Regular access to blood meals can extend their life. 

Nymphs (Juveniles): Require frequent blood meals to molt and progress through 5 stages over several weeks. 

Dormancy in Cold: Can enter a semi-dormant state in cold temperatures, slowing metabolism and prolonging survival.
