Cheap traps:
Cut the top off a two liter bottle, but inside one of those push button LED lights, and push the top of the two liter bottle down inside with the neck pointing toward. Turn the lights on at night in dark rooms. Those stinkers are attracted to the light and fall down the bottle neck like a slick funnel. They can't figure out how to fly or climb back out.
This works.
I've made them.
