Stink bugs seem to have an extended lifespan because they enter a hibernation phase in the winter known as diapause. During this phase, stink bugs do not feed nor reproduce. In spring, they re-emerge, and the females begin to reproduce again.

The type of stink bug that flooded Maryland in 2010 and spread across the U.S. was of an Asian variety. Known as the brown marmorated stink bug, it arrived in the U.S. via an overseas shipment and most likely left its natural predators behind. Some predators, such as predatory stink bugs, assassin bugs and two egg parasitoids, do prey on marmorated stink bugs, but because these predators eat other bugs as well, they are not enough to control the stink bug population.
