Your best bet would be assassin bugs and birds to eat the stink bugs. Also, most species of stick bugs actively hunt each other. But other than that, two thing they hate are garlic and mint. My grandma used to have a planter outside each window with mint plants. Then she would cook up a couple bulbs of garlic in a huge pot of water with a couple sprigs of mint until she got a concentrated mix of the two. She would freeze half of it and use the other as a spray. It's a safe way to get rid of the bugs. You can spray the outside of your windows to keep them outside of your house if you can tolerate the smell. But if you garden, definitely used mint and garlic to protect your plants.
Another solution is to get a soapy solution. Because of the way insects breath, you can cover them is soapy film and they will suffocate. It's a horrid way to die but if you get clusters of stink bugs, it might be a way to maximize killing them and reducing their chances for reproducing more.
Third idea, less popular because there is a risk for spreading some diseases if you get a sick animal. But if you could try to encourage bats to come live by your house. Bats are natural insect predators so they should appear naturally if you have them. I'm not so sure about having them as pets but they are pretty cute.
