George found this online:
Attract natural enemies. Stink bugs have many natural predators who can be invited to hang around the garden. Wildflowers and herbs will attract parasitic flies and wasps. Predators such as birds, toads, spiders, and praying mantises will make their homes in perennial herb and flower beds and small shrubs near the garden.
I also do companion planting were one plant will attract the bugs more than the plants you want saved. You could check that out online too
