Entomologist Brian Kunkel tells The News Journal of Wilmington, Del. that the best thing homeowners can do to keep out stink bugs is seal cracks around windows, doors, dryer vents and other openings.
The bugs showed up in heavy numbers last year from Virginia to New York.
They also pose an agricultural threat, with the risk highest to fruit crops.
