We're completely invaded in NH - best trick I've learned is leave a shallow pan of water in kitchen with desk light shining on it all nite - rinse and repeat every day :-(

There are a few different similar approaches around the web if you dig. You simply chop the top segment off a large plastic soda-type bottle (2 or 3 liter), invert it inside the body segment, tape it in place, put an LED light in the bottom, and set it out at night (or ideally in an attic where they may be entering). They go into the trap and can't get back out. Automatic stink bug collection device.
