The contraption consisted of an insulated one-third-gallon jug (you can find them in camping stores) filled with about 2.5 lbs. of dry ice pellets. The spout was left open, allowing carbon dioxide — the telltale sign of a breathing, blood-filled meal nearby — to seep out, enticing the nocturnal insects for some 11 hours.

The creatures don’t discriminate in the places they infest — they’ve been found in apartment buildings, hotels, dorms, schools and even [subway stations](http://cityroom.blogs.nytimes.com/2008/05/09/where-bedbugs-ride-around-besides-just-beds/).
