It’s not often I call a critter “unwelcome”. I welcome most critters found in these parts of my yard, and home, knowing they were here before me. I think we should learn to live with them. What would our beautiful yards and gardens be without raccoons, squirrels, bees, butterflies, worms and the like?
But there is one critter I can safely say is unwanted and loathed. Even by me. You can call me Ms. Nature Girl any other time, but I’ve recoiled at them buzzing around me, and flicked them off my arms and clothes. You may have seen them smacked on the outside of your house and windows or crawling on your carpet. The little rogue is called the Mammorated Stinkbug. Shaped like a shield and skinny enough to fit into cracks and other small openings, the stinkbug invasion is here, and they aren’t even close to being a respected native.
A short history: The stinkbug is known to have arrived on these shores, in a box from Asia, about 1998. I opened a box the other day originating from China, and there he was— the dastardly hitchhiker ready to find a feast in his new world, and surviving for almost a month undercover through a long shipment process.

First recorded in Allentown, PA, the stinkbug has reproduced off the charts and is now in most northeastern states. Even western states are starting to see them. There is no known predator for them or their eggs in these parts, and they are reproducing at a fast clip. In some parts of NJ and PA they are epidemic—hordes of them swarming and desperately trying to get into warm houses for the winter. Known to emit a foul or funky smell when squished, these little guys have gotten a lot of attention and caused a bit of panic in some areas. In parts of Pennsylvania, they are starting to impact fruit production. The feed and “suck” on fruits, causing a bruise called “cat-facing” which makes the final product unmarketable to the public. Crops such as apples, pears, peaches, raspberries, cherries, green beans, corn and soybeans have been ruthlessly attacked enough to make an impact.
Long term management of this bug is a tough one. Insecticides inside are really not an option unless you consult a professional exterminator. The only suggestion the experts give is sealing up areas around your home where the little critter can get in—windows, doors and broken screens. Vacuuming them is a help as long as the bags are emptied right away.
There are horror stories from farmers in Maryland, Pennsylvania and NJ about crop damage, and the daily sweeping of thousands of the invaders off porches and house walls. In some parts of these states, the stinkbug has ruined 20% of the apple crop. It’s always something, I say, and I guess we can live with this too. But, who wants to? They stink, fly into your face, and I have wracked my brains and come up with a few homespun solutions since the stinkbug has arrived at my house.
I have seen many of them caught in spider webs as they try to enter the house. Although they look like a big treat for any self-respecting spider, the spider has a tough time breaking this little dude down. But, the stinkbug dies in the web, and that’s all I care about. Leave your spider webs up. Inside and outside. Spiders are ok around the house. Even inside. Ok, you might say “eww” or “yuck”, but, I’m serious. They don’t bother anyone, and the little stinkers get caught in the webs.
Another trick I’ve tried is putting fly tape or packing tape on the window wells with the sticky side up. The legs of the stinkbug aren’t too strong, and they get caught and die on the sticky tape surface. I’m no entomologist, and this is not too professional, but, it works. One by one, that’s all I want.
Beware of internet scams and so called “secrets” to permanently getting rid of this nuisance. They are all over the web, and they charge a hefty fee for pitiful advice.
Never fear though, our beloved Rutgers University is on the case studying the stinkbug and it’s destruction to NJ crops and invasions into our homes. On the Rutgers site page,
Monitoring for the Brown Marmorated Stink Bug they ask for the public’s help in informing them when you see one in your area. Go on the site and learn more. There’s no cure-all, but you’ll always find truthful info there.
There’s a little bit of progress. Researchers are studying a type of parasitic wasp that feeds on the stinkbug’s eggs. This might take years since the wasp may prove to be invasive as well. The red tape goes on, but the Department of Agriculture is trying to get the bug reclassified so farmers can use stronger pesticides. $3 million dollars have been allocated for studying these pests. But, hopefully, this record year of reproducing bugs won’t be repeated. Whether it was the incredible heat, or just their time, scientists are on the case.
When you see the stinkbugs retreat someday, thank a scientist. They are studying this aggravating nuisance all day. Life isn’t as simple as it used to be, we are rampant, impatient consumers. Imports come in from thousands of miles away, and the incredible hitchhiking stinkbug has come in with our pleasures. Farmers say nothing will be done until Mr. and Mrs. “Consumer” can’t find their favorite fruit in the summer. Then there will be help. But, until then, batten down the hatches and squish them or flush them and hope for the best. Maybe China will check for bugs before it ships. Right.
