What, exactly, is a stink bug?
Oh, I Googled it, never mind. I would light a fire with flue closed, climb on roof, and as someone opened the flue I would pour gasoline down the chimney.
Damn that is gross.
I had to Google stink bug.
Never heard of 'em.
Be careful with your method of extermination…don’t want to have their stink wafting through your house forever.

Before you light any fires, I will gently point out that doing so may have odoriferous consequences. In other words, you currently have a chimney full of stinkbugs–do you want to trade that for a chimney full of boiling stinkbug juice?
Non-flammable solution: throw a couple of stink-bug-lovin’ hens down the chimney.
Count yourself lucky.
Nosy neighbors.
The weird thing is that they don’t actually stink at least in the way raw sewage or a dead body does. Instead, they smell like lotion or soap you would get from the clearance rack at the dollar store. The smell certainly isn’t pleasant if it is concentrated but it isn’t like it would smell like a million bugs are farting in your chimney. It would smell like they are wearing the worst bug perfume imaginable.
I would just light a big fire under them and be done with it. Either that or throw some chickens down your chimney too.
How about lighting a chicken on fire and throwing it down the chimney?
That’s always hilarious, stink bugs or not.
Stink bugs are bad, but should you really be resorting to voodoo? 
This was the summer of the stink bug. I have never seen so many as we’ve had this year.

We never see any during warm weather. Fall and winter we see them indoors.
And forget about harming chickens! My gf loves our hens. When a stray dog tore one up a few years ago, she paid the $300 vet bill to put it back together.
Waldo?
Hold a big bag open in the fireplace, big enough that the opening is bigger than the chimney, then open the flue to drop them into the bag. If necessary, use a broomstick or something to shake them up. Then take the bag away and dispose of them somehow (out to the henhouse, or to someplace far away if there are too many for that, or maybe just seal up the bag well and toss it in the trash).
Only if kayaker wants to perform a ridiculous experiment in an attempt to prove that the Stink Bug Holocaust never happened.
Sounds interesting; flew/flue chicken. Can I haz the recipe? 
Use a shop vac to suck them up. Every time I go out to the garage there are probably 30 or 40 hanging around the windows. The shop vac seems to be the easiest way to get rid of them without getting sprayed.
