Soap and water sprays applied directly to them at dusk is a good control measure which is relatively nontoxic to other insects as long as it is directed at the stinkbugs. You can buy Safers insecticidal soap at any nursery or garden center and it will be safe for plants listed on the label. Commercial insecticidal soaps are safer to use on plants than making your own from dishwashing liquid.
There are more toxic insecticides you can use as long as you don’t spray your fruits or vegetables with them. Be sure to read the labels of pesticides before buying and applying.
