Latest Wisconsin Pest: Brown Marmorated Stink Bug

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

A surge of invasive bugs has washed over our Vernon Hills neighborhood Pewaukee and Wisconsin in the past 2 decades: the emerald ash borer and gypsy moth to name a few. All are native 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 stink.

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 traveling 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, odor guaranteed to wrinkle your nose. Probably not a {visitor you'd invite into your Vernon Hills house, right?

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

Farmers abhor them for more than their smell. The insects 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 Vernon Hills your house. If you crack one, you'll figure it out quickly. The nose knows.
