Brown Marmorated Stink Bug

(Halyomorpha halys)


The Brown Marmorated Stink Bug (Halyomorpha halys) is a ‘True Bug’ belonging to the insect order Hemiptera. All true bugs, such as bed bugs or boxelder bugs, have long piercing/sucking mouthparts that are used to drink fluids. The Brown Marmorated Stink Bug gets its name from the brown, marbled markings covering its body. The Brown Marmorated Stink Bug is an invasive species. Although it can be easily confused with native stink bugs, an easy way to identify this species is to look for the white bands on the end of its antennae. This species also has a white and black checkered pattern along the edge of its abdomen.



The Brown Marmorated Stink Bug is a important agricultural and urban pest. It feeds on fruit and vegetables such as apples, tomatoes, peaches, green beans, soy beans, and more. It uses its piercing/sucking mouthparts to puncture the outer skin of the fruit to drink the fluids inside. Its saliva can cause necrosis or tissue death to the fruit that it feeds on, leading to large unappealing blemishes or plant death. Like other stink bugs, the Brown Marmorated Stink Bug can give off a foul odor if disturbed.

These insects are highly attracted to white or light colored buildings, especially in the fall when they are looking to ride out the cold winter months. During the fall they will aggregate on buildings in large numbers, looking to enter into attics, window sills, chimneys, or other openings into the home.


Other than the damage it can cause in your garden, typically the only indication of a Brown Marmorated Stink Bug infestation is when they congregate on houses or buildings in the fall.
