This is what japanese beetles look like, could tell them apart easily.

But sounds like they're working their way west, just like the jap beetle has.

The traps attract more to your garden. The only way I've seen them effective is where you can encircle your garden area by placing them several yards outside of it. They are yucky to clean, change, and keep up with.

I remember the green stink bug since I was a kid but not this one. Anything that would work in the midwest to eradicate both of these pests would be a good thing. In the east they have introduced a parasitic fly that feeds on the female but not before she's laid some eggs.

The U of MI has been working on a virus that will spread from adult to adult, but that was a few years back, and I haven't heard of anything since.

The only pesticide that really works are those in the neocontinoid class which have residual action, even after a rain, but it kills bees and wasps. I sprayed with Sevin, and it washed right off the next rain, used the max recommended by gardeners, and didn't seem to phase the pests.

Milky spore doesn't work well in the midwest.

One thing my neighbor used that might work on the stink bugs, too, is food grade diatomaceous earth, wet down the plants and sprinkle. It's gritty, and they don't like it. Don't know if it would be cost effective for a large growing operation or not.

I have a couple of pounds of the food grade Diatomacious earth and I plan to use it on these guys this summer. Have you actually used it?

Japanese beetles are one of the few* natural attackers of a Japanese botanical pest, “mile a minute” vine (some call it “triangle razor vine” or “tearthumb” which has been spreading across southern Pennsylvania and northern Maryland.

Like the beetle and the stink bug it was a stowaway.

*Whitetailed deer are discovering the vine and will devour it. The deer have become overpopulated but the good unitended consequence is that they are controllng this pest as well as multiflora rose.

Thank you for your very in depth and informative post.

Mine were meant as a /jk.

It must be me.

I thought anyone could tell them apart easily.

BTW, my father is a Grand Master Gardener of The Most High. If you are interested, I could ask him for advice on how to deal with the nasties. He also has his Master's in Agronomy, and spent his whole life in agriculture. So he knows his stuff.

Have you tried Malathion?

I think Parathion was banned. And Monitor 4 Spray may have been banned. Monitor is some nasty stuff. We asked the spray pilot one day how you could tell if you got a dose. He said oh, you just stop breathing.
