It feels like we are being bombarded by bedbug stories. Turn on the radio, open a magazine, walk by a TV and there is another new story about the bedbug invasion. Especially in big cities, and a lot of them are in hotels.

If you hear enough of these stories, you may get to the point where you are afraid of going to a hotel. You might also be worried that bedbugs are moving into your home. So what are you gonna do? How do you find out if you have bedbugs or not in your home or hotel room?

Mosquito magnets are pretty big and expensive, however. If you want to make an inexpensive trap, you need a cheaper, easier source of carbon dioxide. One possibility is dry ice, as shown here:

Two other techniques for detecting bedbugs involve tape and visual inspections as seen here:
