Help. We are overrun with immature stinkbugs. We have identified them from pics at some insect identifier sites. The bugs are all over the exterior of our house, and now coming indoors. We have tried soapy water (Pinesol) with some success, but in a few hours, they are back. It's just like the mature insects, all over the exterior of our house in late summer/fall. In one square foot area, there were at least 60 - 70 of the buggers. I believe they are coming from the ground surrounding our house. Can you recommend anything?
