Brown Stink Bugs
How do I get rid of Brown stink bugs in my home?
Clackamas County Oregon insect issues
Unfortunately we don't yet have a good solution to this new pest in Oregon. The best advise is to treat it as you would the more familiar boxelder bug to which it is somewhat related. See http://www.livingwithbugs.com/brown_marmorated_stinkbug.html and http://www.livingwithbugs.com/boxelder.html for a review of these options (these are my personal web pages, your county Extension office has additional info).
