Latest WI Insect: Brown Marmorated Stink Bug

The hits just keep coming, in the form of more unwelcomed six-legged visitors whose real home is across the oceans.

A tide of invasive insects has washed over our Muskego neighborhood Pewaukee and Wisconsin in the past two decades: the emerald ash borer and Asian beetle to name a few. All are native to foreign countries. All have caused environmental and economic mayhem in the United States, where no natural predators exist to control them.

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

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 traveling west since being first discovered in Pennsylvania in 2001.

Its name is well-earned. When smushed or stepped on, the brown marmorated stink bug emits a strong, creature you'd invite into your Muskego home, right?

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

Farmers dislike them for more than their stink. The stink bug 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 U.S. The insect 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 Muskego your house. If you smush one, you'll figure it out quickly. The nose knows. If you see more in your Muskego house or yard, don't step on 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.
