Latest Wisconsin Pest: Brown Marmorated Stink Bug
The hits just keep coming, in the form of more uninvited 6-legged visitors whose real home is across the waters.
A surge of persistent insects has washed over our Caldwell 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 U.S., 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-earned. When disturbed or crushed, the brown marmorated stink bug emits an awful, pungent you'd invite into your Caldwell house, right?
Fortunately, the brown marmorated stink bug hasn't arrived in large numbers in Caldwell 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 smell. 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 United States. 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 Caldwell your house. If you step on one, you'll figure it out quickly. The nose knows.
