Stink bugs are a pest that damage crops and cause economic losses for farmers. They eat fruits, crops, and seeds. While they are generally harmless, stink bugs can cause millions of dollars in damage each year to farms in states like New Jersey, Maryland, Virginia, and Pennsylvania. They are difficult to control because they are immune to common pesticides and have no natural predators. Researchers are working to develop new methods to address the stink bug problem but currently there are no very effective solutions.
