Some of the "Stink Bugs" can be pests while many others are predators of other insects, so due care in control and proper identification of those that are pests needs to be made. Insecticidal soap has been somewhat effective, Neem oil products also seem to be somewhat effective, and pyrethrin based sprays and dusts have for a long time been the most effective but tend to eliminate the predators as well as the pests.

Thank you, kimmsr. that is a neat website! It is the green one. I have to wonder how much damage they do, or maybe I could get some preying mantis'? Brandy

They will ruin your tomato crop, unless you don't mind cutting out hard white/yellow areas in the fruits. They don't do a lot of damage all on one tomato but rather maybe just one area on many different tomatoes--think of the way squirrels eat chunks out of many tomatoes or birds pecking strawberries--you wouldn't necessarily mind if they spent their time finishing up just one & leaving, but they don't and have a taste test on many! The light spots are hard an inedible.
