Latest WI Insect: Brown Marmorated Stink Bug

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

A tide of invasive bugs has washed over our Algonquin neighborhood Pewaukee and Wisconsin in the past 2 decades: the emerald ash borer and gypsy moth to name a few. All are innate 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 smell.

The brown marmorated insect 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 smushed or crushed, the brown marmorated stink bug emits a strong, overpowering you'd invite into your Algonquin house, right?

Fortunately, the brown marmorated insect hasn't arrived in great numbers in Algonquin or Wisconsin. 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 odor. 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 family member 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 Algonquin homes. If you step on one, you'll figure it out quickly. The nose knows. If you see more in your Algonquin home or yard, don't smush 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.
