I have an extreme infestation. I am in a residential community in the south hills of Pgh and of all the homes mine is the only one that has stink bugs completely covering everything outside. I believe it is the huge tree we have out front that they nest in and have contemplated cutting it down. If you need somewhere to research this would be a researchers dream. I have sprayed every chemical out there, and used a trp but they are still attacking my family as we leave every day and it is getting so unbearable my husband wants to sell our home.
