The Brown Marmorated Stink Bugs are found in Asian countries and in the southern United States. They can become agricultural pests as they have the potential to cause widespread damage to fruit and vegetable plants. They commonly invade maple trees, birch trees, apple trees, orange trees and pecan trees. They also target plants such as tomatoes, grapes, cucumbers and sunflowers. They feed on the plants by sucking from the fruits, causing crop necrosis, seed loss and introduction of plant pathogens. During winter, brown stink bugs invade warmer homes, hiding in windows and door frames.
Green stink bugs originate from countries such as China and Japan, earning them the name "Asian Stink Bug." They feed on soybeans, corn, apple trees and cherry trees. Because of their color, they often go unnoticed by blending in with the surrounding foliage. Their natural camouflage provides an additional benefit during mating season. They are able to discreetly lay eggs on plants and increase the population.
