Latest Wisconsin Pest: Brown Marmorated Stink Bug

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

A surge of invasive species has washed over our Chittenden neighborhood Pewaukee and Wisconsin in the past 2 decades: the Japanese beetle and Asian beetle to name a few. All are native to foreign countries. All have caused environmental and economic havoc 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 journeying west since being first discovered in Pennsylvania in 2001.

Its name is well-earned. When smushed or crushed, the brown marmorated stink bug emits an awful, overpowering you'd invite into your Chittenden home, right?

Fortunately, the brown marmorated stink bug hasn't arrived in large numbers in Chittenden 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 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 Chittenden your house. If you step on one, you'll figure it out quickly. The nose knows. If you see more in your Chittenden house or yard, don't step on them – contact The Mosquito Guy to address their presence in a safe, non-stinky fashion.  Unlike these bugs, we'll never stink up your joint.
