Damage
Stink bugs attack a variety of fruits and vegetables from stone fruits to pears to beans to tomatoes, often leaving blemishes, depressions, or brown drops of excrement. On green tomatoes, damage appears as dark pinpricks surrounded by a light discolored area that remains green or turns yellow when fruit ripen. Areas beneath spots on tomatoes or depressed areas on pears become white and pithy but remain firm as the fruit ripens. On peaches, fruit turns brown and corky.

Solutions
Handpick bugs or their eggs. Eliminate groundcovers or weedy areas in early spring before populations build up. Insecticides are generally not recommended in gardens for stink bugs. Parasites and general predators may contribute to control.
