"So, do you have lots of stink bugs?"
"Oh, yuck, yes. Thousands of them. A lot more than last year. They're all over the screens and we're keeping all the windows and doors closed to keep them out."
A good idea, one much touted on the news, but impractical when one has indoor/outdoor cats who always want to be where they're not. Even against stink bugs, nine cats and their annoying requests win the day.
And below the cut, I describe my battles with the bugs and my conclusions about how to deal with them.
So. Two years ago we had a few and weren't sure what they were. They were mostly on the produce on the counter. Weatherdude thought they were "potato bugs." Mindseas told us they were shield bugs. Whatever they were, they were butt ugly. One year ago there were more of them. Weatherdude eventually discovered they had taken up residence in our chimney and he started a fire, which took care of that problem. We also had a 'broken' heat pump (which actually wasn't broken at all, see posts from a over a year ago http://birdhousefrog.livejournal.com/120708.html) and the repairman found the stink bugs were in there, too. They like electricity and they like heat and dark spaces. So they're in your heating ducts all winter in the attic. Occasionally, they fall out. Onto unsuspecting humans sitting beneath the duct. Ugh. As the weather gets colder and winter unfolds, they get slow and old and easy to catch. We spent a lot of last year catching them and tossing them outdoors into the cold. bwah, ha, ha.
And now this year. Stink bugs have infested this area enough to be all over the local news, much as bedbugs are in NYC. (I'd rather have a stink bug problem.) Suddenly I was seeing them in several rooms of the house. And I wasn't sure where they were coming from. And then one day, much to my disgust I discovered they covered the back side of my lined floor length drapes in the dining room. Oh, ugh! And they were all over the walls. And all over the glass door and screen. And all over the lamps. And all over the windows in my office which is right above the heat pump they seem to love so much. I closed my windows, but that meant they were between the screen and the glass, inside. Ugh, ugh.
Stink bugs get their name from the stench of crushing them. Stink bugs can be vacuumed. Then your vacuum cleaner smells like stink bugs. For a long time. Even with a hepa filter. So Maralton and I vacuumed the stink bugs, took the bag off and disposed of it outside in the trash barrels. And two days later, we did it again. And two days later, again. By this time, G-Dude was doing work around the place and couldn't believe the number of stink bugs. Which made me roll my eyes, because, yanno, I'd already vacuumed up a cool thousand of them at least. No lie. And a few days later, there they were again. I discovered them in new locations, such as the cabinets, hiding on the back side of a rolling door for hanging file folders. How did I find out? I accidentally let go of the door, it slammed down and a whole bunch of stink bugs fell to the bottom of the cabinet when I opened it again. Oh, ugh. So I did it lots more times and vacuumed them all up. They scurry like anything now when we turn on the vacuum.
So here's G-Dude and it's like Tom Sawyer and white-washing the fence. He wants to borrow the vacuum and he vacuumed them up off the side of the house and the garage and inside the wood shop and everywhere he could find them. And he went to the hardware store (we have a REAL one in town, the old-fashioned kind that carries everything and has a wall of little drawers with no labels on them) and they were selling some Ortho product they claimed would kill them. And at my wit's end, I reluctantly agreed to let G-Dude use some on them. Only it doesn't really stop them or kill them in their tracks. And I hate using pesticides because they're indiscriminate. I let him coat the side of the house where the heat pump is and a few other places and then I asked him to stop because he was getting carried away, as he does, with the attack on anything. G-Dude hates things like wasps and bees and snakes, beasties that Weatherdude and I actually like. And then he heard that vinegar works. And rubbing alcohol. And soapy water. And I heard that you should drown them. But they just kept moving and climbed back out of the cats' water bucket. And all I could think of was MIB and the bug alien and that they were already here, the alien bugs. And G-Dude said he'd seen some program about what the world would be like if humans were gone and only animals remained and he thought about my house and yes, it would be open to the elements with lots of feral cats living in it along with a mighty mass of stink bugs.
Then it got colder and no stink bugs for a week. That was nice. Then it got warmer again. And Weatherdude came home from where he was and he got the vacuum out and got them off the back of the drapes again and found them on the back of other hangings and behind pictures and all that ugly stuff. He discovered that if you walk away for 10 minutes after vacuuming, they all come out of the cracks they're in and you can vacuum them up. He shook out the plastic cover for his grill on the deck and it had a few thousand stink bugs in it. And when they came back up out of the cracks in the deck (he shook before he had the vacuum ready), he vacuumed them up too. He went through a couple of very full vacuum bags. And showed me how they were all crawling all over the shingles on the roof, too.
But. We were actually beginning to make a dent in them. There were fewer and fewer. The problem, though, was what to do about them when there were only a few at a time. I had been waiting for critical mass to bring out the vacuum, but that wasn't a really viable option when they were acting like buzz bombs and dropping out of the air while one sat on the couch. We were noticing that the hunting spiders were congregating, but there weren't enough spiders around and I really prefer it when the spiders work outdoors. I needed a solution for a smaller number inside the house and it was overkill to toss them into the drain and run the disposal. Sometimes they just climbed back out. By accident I found the solution when I flipped one into a plastic container that was soaking in the sink with some dishwashing liquid in it. Aha. Soapy water does work, but not as a spray. Flip them into it and they don't climb back out. They die. Their little wings open up and that's the end.
So there you go. How to control stink bugs.
1. Seal your house against the siege, which really doesn't reduce their numbers and guess what? next year a lot more will be back trying to get inside.
2. Vacuum, wait 10 minutes, vacuum again, rinse and repeat for an hour. This works. Seal up the bag immediately and get it out of the house into the trash barrel. Otherwise, they will crawl back out.
3. Keep a soapy dish in the sink and grab them one or two or three at a time and flip them into it with a good flick of the wrist.
Note that items 2 and 3 will hopefully keep them from increasing in numbers the next season. Presumably, they don't lay their eggs indoors. The rumor is that they lay them in your gutters. Which should be cleaned out with a bleach solution to kill the eggs. Time will tell if that's true. And by next year, we expect that someone will have developed a trap, like we have for japanese beetles.
As for me, I've come to like the smell. No, I'm not kidding. It's like that line from "Apocalypse Now." Yes, that one. "I love the smell of napalm in the morning. It smells like...victory." That smell is the smell of dead or maimed stink bugs. It's a great smell, the smell of victory.
