I'm 'fortunate' to live near the US 'ground zero' for these and the stinkbug. The lanternfly seems pretty rare now, but those stupid stinkbugs (brown marmorated stink bug) are still everywhere.
From what I understand, the lanternfly is worse for crops, but the stinkbug, in my opinion is a far worse residential pest. They fly like they're drunk; constantly crashing into things with an audible clunk, and they're able to sneak through cracks/holes that don't seem possible. It's almost impossible to actually exclude them from your house, and once they're in, there's not many good ways to kill them without releasing their nasty odor. Even squashing them with a folded-over paper towel, the stink can still get on your fingers.
The best way I've found to kill them is to use an inverted air-duster spray, where the cold liquid propellant instantly freezes them before they release their malodorous oil. They drop off what they were clinging to, and they can be thrown away.
Fingers crossed I have not seen the lantern fly's in Michigan yet. Stinkbugs were more prevalent about 2 years ago, but not as much recently.
The stink bugs are my arch nemesis as their scent chemical is probably the most repulsive scent imaginable for me. It smells exactly like cilantro, too. When I lived in Virginia they were everywhere.
My stink bug weapon is a 2-liter soda bottle filled about 50% with warm water blended with dish soap. I fill a bottle with warm water, drizzle some soap inside, shake it up and it is good to go. I will walk around my home with the bottle slightly squeezed so that once I release the squeeze it creates a vacuum effect. I'll position the nozzle of the bottle right below the bug as I release and it sucks them in every time. They fall into a foamy bubble bath and die a silent death. I've collected hundreds of them with this method. Fortunately this year I have only seen 2 on my property.
protip do not use a vacuum cleaner to suck up stink bugs as it will essentially turn the exhaust port on the vacuum into a cilantro/stinkbug scent emitter machine
I've made the vacuum mistake before, and I had to throw the vacuum bag out well before its time. Same issue if I crush one and throw it in the trash can - now I have that smell until I take the trash out.
Based on some responses, it's clear there must be varying ability to smell/be offended by the stink chemicals. Maybe it is like cilantro in more than just odor, because I am part of the unlucky genetic group that finds cilantro to taste like soap.

This also works instantaneously on all sorts of household pests, including roaches.
In the U.S., these spray cans typically have a bitterant that smells horrible and sticks to your hands. It’s especially bad if you turn them upside down. It’s not worth covering your house in that smelly stuff IMO.
I bought a Bugzooka[1] and it works great to catch stink bugs and similar slow insects. It safely traps them alive, does not stink the house, and allows me to easily catch 10-15 bugs before I need to empty it outside. It is humane, kind of fun, and I can operate it from a safe 2-3ft distance. Plus my 3 year old absolutely loves it!

Same. Never smelled them. I don’t squeeze, just wrap them up so they can’t get out. Maybe I should squeeze one eventually. Sadly my chickens don’t seem overly interested.
Bug a salt. It’s wonderful fun. If you can stomach “assault guns. “ I can and it’s great and wonderfully effective. Also kinda fun too. I hate flys. Stink bugs, meh.
Your options are to put them in a container with a a weak dish- or hand-soap solution (a mug or yoghurt tub with a few drops of detergent + water will do the trick). They'll die in a minute or so. You'll get some smell though it's usually not too strong if you avoid crushing them. Dispose of the dead ones within a day.
You can also use a (diluted) detergent spray, and apply that directly to groups of the insects, particularly where they're gathered on exterior walls, plants, etc. That's effective diluted to 25%, and almost certainly further.
Any detergent seems to be effective, specific brands don't much matter. If you need a specific recommendation, a cheap Dawn detergent should work.
For a passive solution: soapy water + vinegar traps can be used. Tubs, buckets, reused plastic food containers, aluminium foil pans or trays, roasting pans, etc., all make excellent traps.
I've found as soon as I touch/disturb one, it excretes its stink oil onto my fingers. The smell also permeates the room a bit.
I beg to differ on the 'they don't want to be inside' bit. I think that's exactly what they want, since they tend to swarm enclosed structures in the Fall. I assume they prefer a climate controlled house during Winter like most other insects/animals would if given the option.
They want to be inside of your house in the northern US, this time of year when it gets cold they will crawl in any opening. Then they die because they can't get back outside.
I just grab a sheet of paper, scoop them up, take them outside, then squish as they go into the trash. They’re usually quite content to just walk up onto the paper and go for a ride.
I'm in Pittsburgh, and they are everywhere. Have you ever seen a place overrun during a cicada emergence? There's about that many. Every time I take a half-hour walk around the neighborhood, I kill at least 10, sometimes 50 or so. I've noticed that they like dark things/places and humming noises, like power poles with transformers on top and rail stations.
My strategy: approach them from their front and stomp on them. They like to jump forward, so coming at them from any other direction is less successful.
I figured that I would find one inside my house at some point, and found a dead one under the dining room table a month ago.
In Pittsburgh too. For some reason the back entrance to my building (TCS hall) is a mecca for these little pests--to the point that a brick wall was literally covered in thousands of them. I ninja-side-kicked said wall and hit nothing but lantern fly. I must have killed almost a hundred with just a couple kicks. Crazy.
Clearly natural selection is at work because the left over ones are getting pretty good at jumping out of the way of a stomp.
They may be getting better, but they're still pretty stupid. Also if you decide not to stomp one and instead pick it up by its wings, it just instantly gives up and stops moving. I got too tempted one time and ended up eating one.
The railroad right of way that passes nearly under TCS is packed with the lanternflies favorite host species, ailanthus (tree of heaven). There's a large band of them running all the way from the river up panther hollow to Carnegie Mellon. It's a perfect breeding ground for the lanternflies.
I'm hoping the Tree of Heaven will be controlled. They've found a pathogen (Verticillium nonalfalfae) in Pennsylvania, Ohio, and Austria that seems highly effective at controlling it.
Interesting. I usual try to sneak up on them from behind as they see / sense when I didn't.
They're quick but don't seem to have stamina. That is, first stomp might miss. Second stomp might sometimes misses as well. But by the third the battle is over. I win.
These things are everywhere in Manhattan; a few weeks ago there were so many it took concerted effort not to step on one on the sidewalk. They don’t appear to be particularly intelligent either, and as such the ground is littered with their dead bodies, crushed underfoot by pedestrians. It’s gross.
I lived in Pennsylvania near the initial impact zone when these first arrived, in south Jersey a few years later, and moved to new York city about a year ago. The fly is now present in all 3 of these and was when I lived in those spots, but what's interesting is the amount that I see them has decreased every time I visit back to any of these places, particularly in southeast Pennsylvania where I used to see them all the time.
Anyone know why this would be the case? State eradication efforts were in full tilt for about a year or two in 2019 when I saw them all the time in PA, so I'm guessing it's some kind of combination of new predators emerging or the population becoming less dense as it spread out?
I live in a woodsy suburb in SE PA, and saw that first infestation. It was horrible. Disgusting. The next year was way better, and by this year (I can't remember if this is year 3 or 4) there were hardly any. There are definitely predators catching on--I've seen praying mantises and various spiders eating them. I think I've heard that some birds have caught on, too.
What I don't know is at first we heard that it's a little colder than they like around here, and that we should expect them to move south. I haven't heard that it's bad south of here, but I don't know.
I don't think even the authorities know which of their efforts are most effective. Their numbers do seem to be declining in some places, which is heartening at least.
As far as I know, the authorities have done... nothing? I don't know that I would want them to do anything either, I suspect like stink bugs before them, they will enjoy a season or 2 of rapid population growth followed by a decreased population in subsequent years as they acclimate to their new environment.
For those taxonomists types the taxon in question is here, on a new type of taxon-page. The curators are waiting for official channels (e.g. GBIF, museums) to include vouchers prior to updating the distribution.
Their natural predator in China is a parasitic wasp which, if introduced, would likely decimate native insect populations. The government is considering it as a last resort, but as you can imagine it's not a pretty alternative.
This is true. Actually discovered my first oak gall this season and reading up on the specific wasp that can make an oak make an apple and then the specific wasp that puts parasites into the parasite and so forth. Anyways, fascinating.
Another step you can do is locating any egg husks on trees in your yard and scraping them off. At the very least it'll keep the nymphs from showing up on those next year.
Penn state ag department has some good resources on the fly
If it's otherwise healthy, they won't kill it or even hurt it that badly. They loved the black walnut in our yard and I was worried about it, but by the next year they were mostly gone.
