This is a common question. Many people who rent carpet cleaners usually do it to get rid of bed bugs. The truth is that bed bugs do not live in the carpet cleaner. They are killed by the steam. However, some people still fear that some bed bugs will crawl and hide in the machine. It happens rarely and is almost impossible. However, no one can give you a 100 percent guarantee. This is why it is important to use the steam before you enter the room. If you are worried about it, you can always buy a machine instead of renting it.
