UPDATE: See the November 22, 2022 post “Fewer brown marmorated stinkbugs in WNY? It seems likely!”
by Connie Oswald Stofko
Gardeners are once again beginning to notice brown marmorated stink bugs flying and crawling in their homes. These invasive pests are looking for a place to spend the winter.
They don’t pose any harm to humans and they won’t damage your home. However, they are ugly and annoying in your house. They make a loud buzzing when they fly and a big thump when they land. When you squish them, they stink.
More important, they feed on a wide range of plants. See a list of plants here that they can feed on.
John Farfaglia, extension educator with Cornell Cooperative Extension in Niagara County, said he hasn’t received any samples of plant damage from home gardeners yet, “but I expect that will change in the coming years.”
The brown marmorated stink bug, an invasive species from Asia, arrived in Western New York in 2010. This pest hasn’t established a large population here yet, so there hasn’t been much damage to plants.
At my house it seems like the number of brown marmorated stink bugs has been decreasing since October 2018 (which seemed like a stink bug invasion).
But we shouldn’t get our hopes up.
“It’s good to hear you have not seen many lately,” Farfaglia said, “but last I heard there has not been any change in the longer term forecast that we should see increasing numbers in the future. I hope that forecast changes, but I have not heard anything to the contrary from entomolgists.”
Are you seeing brown marmorated stink bugs where you live? Please leave a comment.
