By. Beth Baumann

Scientific Name: Halyomorpha halys

Common Name: Stink Bug

Anatomical Features: shield-shaped; adults are gray-brown in color while nymphs are orange & black  piercing-sucking mouthpart,  white triangles along margin of abdomen  edge of shield behind eye (pronotum) is smooth, not toothed, Last two antennal segments have both dark and white bands

Damage caused by Stink Bug: They suck all the juices out plant which cause punctures and scars the plant tissue. Stink bugs may feed on leaves, stems, or blossoms, but often prefer tender new growth, developing seeds and fruits. This results in distortion of the growing tissue around the feeding scar.

Most attracted plants: Fruit and veggie plants

Most appropriate ways to distinguish them from plants: Natural Pesticides such as mint oil, garlic spray, and diatomaceous earth.

Reproduction: Because stink bugs won’t reproduce indoors and their food is mostly outdoors, they won’t try to move into until it starts to get cold – usually around late September/early October. The insects sneak in through small cracks and openings in chimneys, door and window frames, air conditioning units, attic vents and holes in a home's foundation. They hide out in toasty, dark spots during the winter, and emerge from hibernation late in the Spring. That’s when you’ll notice them become active again.

Interesting facts: The Brown Marmorated Stink Bug is from Asia. It was first reported in the United States in Allentown, Pennsylvania in 1998.

The “stink” that stink bugs give off when they are disturbed is made up of the same components as cilantro.

Stink bugs cause dermatitis in people when scratched by the sharp edges of a stink bug’s shell or exoskeleton. The result is swollen, reddened, itchy skin.
