Stink bugs appear in spurts and when they appear, they infest.
With their ability to rapidly increase in population, stink bugs can destroy
crops in mass quantities. They have been known to all but wipe out certain
crops in some mid-Atlantic states.
In addition to destroying crops, the brown marmorated stink bug is also
a common nuisance pest for homeowners in the fall and spring.
Watch out for stink bugs in the fall and spring, especially around doors
and windows.
In the fall, these stink bugs will congregate around windows and doors
as they try and make their way inside to shelter for the winter. Unlike
most other insects, their sturdy build allows them to force their way
through door and window seals. In the spring, they emerge from their hiding
places in walls and floors and congregate around the windows and doors
again as they try to make their way outside.
