how long do bed bugs live

Bed bugs most commonly live for about 4 to 6 months, but under cool conditions and without food, they can survive up to a year or more. In laboratory conditions, well-fed adults at room temperature typically live between 99 and 300 days (approximately 3 to 10 months). Some reports suggest that bed bugs can live as long as a year or even up to 18 months without feeding, but this is less common and usually under specific conditions like low temperatures. In a real-world environment, their lifespan may be shorter due to challenges like finding food, temperature fluctuations, and insecticide exposure. Adult bed bugs usually feed weekly, and they hatch from eggs in about two weeks, passing through nymph stages before becoming adults within roughly five weeks in room temperature conditions.
