As bad as stinkbugs are for tomatoes, they are even worse for cucumbers. When they suck the juice out of cucumber leaves, their toxins cause the leaves to shrivel up, and then the stinkbugs hide on the undersides of the shriveled-up leaves where predators can't get to them. Eventually they will kill a cucumber plant by destroying all the leaves.
There is a tiny insect called a Samurai Wasp that lives by parasitizing the eggs of brown marmorated stinkbugs. They managed to hitchhike from Asia to the eastern US a few years ago, and are slowly working their way west. They made it as far as Ohio in 2017, and I hope they make it to Indiana this year.
