Stink Bug Season
The life cycle of brown marmorated stink bugs generally involves mating, reproducing and feeding from spring to late fall. Upon the onset of cold weather, they seek shelter to spend the winter in a dormant phase known as diapause.
Stink Bug Season & Activity
However, entering into diapause may not be the complete end to their season of activity. If the weather warms up for a long enough period of time, indoor overwintering stink bugs might be misled into thinking it’s time to exit their diapause period and become active again.
When Are Stink Bugs Most Active?
The most active season for stink bugs is primarily March through September. But, if temperatures rise significantly during the winter, stink bug season can continue well into the winter months.
