S.T.
they're probably actually making their way OUT of your house, having snuggled happily into your walls, nooks and crannies for the winter. they'll be gone soon, as they prefer to be outside in the summer, eating all your tomato and squash plants. then you'll get inundated again in the fall.
so far no eradication methods. they are utterly impervious to insecticides. and our early spring indicates that they will be in biblical proportions this year.
we have a dedicated dustbuster that is used only for stinkers. (once used thus, they're useless to clean with again, obviously.) i put a cotton ball with a few drops of peppermint essential oil on it to help counteract the smell, but of course nothing really combats stinkbug smell. but it means i don't ever have to touch them, and i'm not flushing endlessly.
you can also get humane bug trappers online for $30 or $40.
i used to think mosquitoes and gnats were our worst Bug Overlords......
