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 waters.

A tide of offensive species has washed over our Stonebank neighborhood Pewaukee and Wisconsin in the past 2 decades: the Japanese beetle and gypsy moth to name a few. All are innate to foreign countries. All have caused environmental and economic havoc in the United States, 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 journeying 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, nasty you'd invite into your Stonebank home, right?

Fortunately, the brown marmorated stink bug hasn't arrived in great numbers in Stonebank 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 odor. The stink bug feast 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 cousin that is native to the U.S. 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 Stonebank homes. If you crack one, you'll figure it out quickly. The nose knows. If you see more in your Stonebank home or yard, don't step on them – contact The Mosquito Guy to address their presence in a safe, non-smelly fashion.  Unlike these bugs, we'll never stink up your joint.
