Saw this article recently and thought I’d share: http://www.southernsare.org/Southern-SARE/News-and-Media/Press-Releases/Virginia-Tech-Researchers-Exploring-Sustainable-Methods-to-Control-Brown-Marmorated-Stink-Bug
We had a horrible problem with stinkbugs until we took out the two apple trees on our property. The population dropped about 90% from one year to the next, after the trees were removed.
I was amused to discover that someone has a whole blog devoted to their hatred of stinkbugs called StopStinkbugs.com.
The stinkbugs are starting to try to come indoors for the winter. Most people recommend a vacuum cleaner to get rid of them. Empty the vac when you’re done, preferably into a plastic bag you can close and throw into the trash.
The good news is that they don’t bite, they aren’t poisonous, they don’t reproduce indoors, and they don’t feed on much of anything inside, either. The bad news is, of course, they smell if you squash them, and their innards can stain walls and furniture.
The best advice is to try to keep them out by caulking or sealing off any openings near doors and windows, and around pipes, outlets and vents. Also seal cracks under your eaves or in your siding and foundation, and replace any damaged screens.
As far as trying to get rid of them in your yard, there are a few species of parasitic wasps that attack stinkbug eggs, which helps to reduce the number of nymphs. And, there are some botantical insecticide dusts that help control them.
The chemical method is pretty nasty and it’s usually recommended you leave it to the pros.
