Latest WI Insect: Brown Marmorated Stink Bug

The hits just keep coming, in the form of more unwanted 6-legged visitors whose real home is across the seas.

A tide of offensive species has washed over our Oak Knoll neighborhood Pewaukee and Wisconsin in the past 2 decades: the emerald ash borer and gypsy moth to name a few. All are resident to foreign countries. All have caused environmental and economic mayhem in the U.S., where no natural predators exist to control them.

The latest invader winging its way here will literally make a smell.

The brown marmorated stink bug is ¾-inch long, with a wide back side that tapers to a point, and a rectangular head with long antennae. Native to China and east Asia, the insect has been migrating west since being first discovered in Pennsylvania in 2001.

Its name is well-deserved. When disturbed or stepped on, the brown marmorated stink bug emits a strong, overpowering you'd invite into your Oak Knoll house, right?

Fortunately, the brown marmorated insect hasn't arrived in large numbers in Oak Knoll or WI. Stink bug control isn't much of an issue yet. Yet it's only a matter of time.

Farmers hate them for more than their smell. The insects feed on tree fruits, vegetables, sweet corn and soybeans. Mid-Atlantic apple growers sustained an estimated $37 million in crop losses in 2010 to marmorated stink bugs.

The Asian invasive has a relative that is native to the United States. The brown stink bug looks a lot like the brown marmorated version, except the colors of their undersides are different. We somehow doubt you'll get that far identifying them, though.

Brown marmorated stink bugs like to winter inside Oak Knoll homes. If you smush one, you'll figure it out quickly. The nose knows. If you see more in your Oak Knoll house or yard, don't crush them – contact The Mosquito Guy to address their presence in a safe, non-smelly fashion.  Unlike these insects, we'll never stink up your joint.
