Stink bugs feed on a variety of plants, including fruits. Some of their favorite fruits include mulberries, apples, figs, peaches, citrus and persimmons.
In Pennsylvania, these bugs are becoming a serious agricultural pest. They produced some serious losses in peach and apple orchards in 2010.
Stink bugs pierce the skin of the plant to suck out the juices. These bugs also love to eat the seeds and foliage of maple, black locust, ash and catalpa trees.
Some species of stink bugs are actually predators and will eat other insects, including harmful caterpillars or even other stink bugs. In this case, stink bugs can actually be beneficial and will help protect your plants.
