One of my garden club members has trained her two dogs to eat stink bugs. They love them and tell her when one is too high for them to reach. This is the best answer for these invasive bugs. Her dogs have had no ill effects over the last year.
If your vegetable plants, especially beans, looked green and lush but produced no beans – stink bugs probably ate the flowers. A friend is researching what biodynamic and homeopathic farmers are doing.
This emphasizes, again, the importance of buying locally raised and made products as much as possible. The Stink Bugs came in with containers from Asia. They are the 3rd worst variety of stink bugs there.
