Seems when I fire up the wood stove, those darn "stink bugs" come out of nowhere. Flexible LED strip gets cut and installed on the inside ring of the ramp. (LED's facing the sloped side.) A little hot melt glue adds to holding the strip in place. I used 9 LED's from the strip. Soldered the wires to a 9Vdc wall wart. The light attracts the pest and they slide down, trapped inside. A little dish soap will make the sides slick also. Add a lil' water with dishsoap in the cup. You can modify the top to hold it in place better. (I didn't want to spend a lot of time on it). I also made another one scaled down .8 and the LED's fit the ring perfectly. Flip the Ramp part for a better print. All I can say is it works...
