The stink bugs are my arch nemesis as their scent chemical is probably the most repulsive scent imaginable for me. It smells exactly like cilantro, too. When I lived in Virginia they were everywhere.
My stink bug weapon is a 2-liter soda bottle filled about 50% with warm water blended with dish soap. I fill a bottle with warm water, drizzle some soap inside, shake it up and it is good to go. I will walk around my home with the bottle slightly squeezed so that once I release the squeeze it creates a vacuum effect. I'll position the nozzle of the bottle right below the bug as I release and it sucks them in every time. They fall into a foamy bubble bath and die a silent death. I've collected hundreds of them with this method. Fortunately this year I have only seen 2 on my property.
protip do not use a vacuum cleaner to suck up stink bugs as it will essentially turn the exhaust port on the vacuum into a cilantro/stinkbug scent emitter machine
