Pest Control: Getting rid of the BRown Marmorated stink bug?

I have 25 acres of apples and pears in Oregon, and the Brown Marmorated stink bug has just come in. What are some natural methods to deal with them? Any predators? I've heard there aren't any native predators to the Marmorated stink bug in North America.

Have you tried black walnut tea (spray or sponged on trees)?

Nope. Is that feasible on 25 acres?

Consider Muscovy ducks. I am a fan of the Muscovy anyway, but I am led to understand that they are more than happy to eat any stinkbug they run across with fervor. Unlike other ducks, they are more than happy to get up into trees and perch, so I can't imagine there are many places for stinkbugs to hide from them either.

Don't know much about ducks. Would they try and eat the fruit or any other growing vegetables?

I've never witnessed one eating fruit, but they will graze at plants sometimes. They seem to favor moving targets in my experience. Tadpoles, small fish, frogs, insects from mosquitos to roaches. They probably do eat some of your produce if it is open to them, but with that much space, they are more than likely going to leave plenty for you. If there are a huge number of stinkbugs, those will probably get a lot more attention from Muscovy ducks than the fruits and veggies will. Normal ducks might eat them too, but I don't know about that. I think normal ducks favor slugs and seedlings over other food. Someone else might want to offer a second opinion though. I have observed them and researched some, but the ones I observed were not mine so I never watched them throughout the seasons.
